3. INTRODUCTION/PREFACE
The overwhelming majority of Americans indentlfy with and pursue the American dream. A key element of that dream Is home ownership, which for the greater part of the last 35 years has been defined as proprietorship of the single family detached house. However, during the course of our history other forms of housing have been of equal Importance in fulfilling the American dream. The row house is a form that dates back to the beginning of our nation. Because of the rise of the suburbs and, thus the attraction of the single family detached house it was not until the 1960's that a suburban form of the row house, the townhouse, re-emerged as a housing choice.
With rising housing costs, shrinking energy resources and significant changes in the demographics of those people entering the housing market, clearly forms of home ownership other than the single family detached housing will be tied to the quality of planning and design applied to them.
Good low rise urban and suburban clustered housing Is as hard or harder to design than a good custom built single family house. The individuals whose needs and aspirations should be given built form are unknown, and so the task becomes to provide an empty but flexible stage for them rather than a complete setting.
It is important to remember that housing like houses, is not just about finance or about government, or about technology, or even about architectural art, but it is about people and their simultaneously individual and social selves.
Main goals are two, and in some ways they are opposite of each other. On the one hand built form is given to a set of individual and personal needs and aspirations. On the other the house should express some more general concerns, responding to both its geographical and cultural place--and whenever appropriate adding to it. The former goal is individual and the latter one socialwhich is to say that the house is simply an expression of people, and of their tentative compromise between their own Individuality (which they need) and their own collective social purpose (which they also need).

4. HISTORY
The +own of Amherst, si+ua+ed +o +he north and eas+ of +he city of Buffalo, and having a land area of approximately 54 square miles, was a part of +he Holland Land Purchase in Western New Yorksurveyed In 1798 by Joseph Ellicot+. The town cen+er originated from the in+ersection of +he "Great Iroquois Trail" and "Ellicott Creek" an area later to be incorporated into +he village of Williamsvfile. Amherst was later incorporated into a town in 1818.
Events in Amherst history carefully recorded by Sue Miller Young in her book "A History of the Town of Amherst, New York", cover everything from Amherst's involvement with the War of 1812 against + he British to the opening of the first tavern and arrival of the first circus.
The population has grown from an estimated 3,133 people in 1845 +o its present popula+ion of 110,000, its proximity to +he city of Buffalo being a major catalyst for grow+h.
The land making up the Farber esta+e was originally purchased in the Ia+e 1800's as the Schelkup estate where Mr. Schelkup buil+ a country home for himself along the escarpment. The es+ate was I a+er purchased by a Mr. Wright in 1920 and eventually by Mr. Farber in 1940.
The proper+y then saw major changes with the northern area below the escarpmen+ being utilized as stables and grazing ground for 200 head of cattle. The southern area was sold for the development of homes in a division formed around Lake Ledge Road in 1950, as well as construction of WiI IiamsviIle High School in 1948.
The heads of ca+tle and s+ables have since disappeared and development of the remainder of +he property became possible wi+h the installation of accessible u+ilities in the 1970's.
Development options and concepts have been formed over the past ten years and a master plan has been developed. Cons+ructlon of +he first structure, an office building, was completed in 1981.
Development of the entire site will occur over the next five years.

6. SITE
ANALYSIS
Site Descrip+ion:
The project site and i + s environs lie within the Erie-Ontario Lowlands Physiographic Province of New York State, immedia+ely north of the Village of WiI Iiamsvilie, in the Town of Amherst, New York.
Site Description: The "Farber Property" fronts on the south side of Sheridan Drive a major east/west ar+erial serving the eastern suburbs of the Buffalo metropo!I+an area. The wes+ern boundary of the property lies 1,280 fee+ east of Evans Street, a north/south local road which intersects with Sheridan and continues northward as Hopkins Road.
The Farber property is bounded on the west by a large tract known as the Jacobs proper+y which is being developed and marketed for a mixture of uses. To date, parcels have been sold to +he U.S. Postal Service for a post office, Liber+y Mutual Insurance Company for an office building, and the Jewish Federa+ion for a high rise elderly housing development.
To the south the property abutts a steep escarpmen+ which serves as a buffer between the site and +he predom i nant I y s i ngIe-fam iIy res i dent i a I d i str i cts to +he south. To the east, the Farber property adjoins the Buffalo Country Club.
The Farber property is generally flat with a small lake and low lying sections at +he sou+h end. This lake is a strong focal point and also provides the mos+ aesthetic area of the site wi + h its large ma+ure trees bordering +he northern and eastern shores. The remainder of the site consists primarily of open meadows with a few small groupings of various vegetation.


-1 4-
The Existing Environment
The topography of the area is a direct resul+ of geologically recent glacial and post-glacial erosion and deposition. Typically, upland areas south of the project site have been mantled by glacial +ill deposits, which range in thickness from several inches +o several tens of fee+ and Immedia+ely overlie bedrock of Devonian age. A location map is included in this repor+.
Cl I mate
The climate of the region is classified as humid-con+inentaI, and is marked by seasonal extremes of heat and cold. In general, the mean annual temperature of the area is abou+ 47 F., wi+h extremes of about 95 F. and -35 F. Precipitation is usually well distributed over the year. However, excessively wet springs occur occasionally and summer droughts have occurred on an average of once every five years. The average annual precipitation is about 38 inches annually as recorded at the City of Buffalo. Of the to+al annual precipitation, it is estimated that about 50 percent Is lost as direct runoff, while the remainder is lost in the processes of evaporation, transpiration and groundwater recharge.
See Section 8 "Energy Considera+ions", for more detailed data, charts, and tables.
Site Geology
Geologically, the proposed site area Is one of geologic stability with little or no earthquake activity. However, in spite of the lack of earthquake activity, the Western New York State area is shown to be in an ear+hquake prone zone. Seismic design evaluations were no+ seriously considered during the developmen* of +he proposed plan.
Si+e Topography and Soil Considerations
The Farber proper+y is generally flat and sloping to the north. A small pond and a low-lying section exists at the back (south end). To the sou+h, the property abuts a steep escarpment, which serves as a buffer be+ween the si+e and a predominan+Iy single family district in the Village of
WiI IiamsviIle. Visibility over the entire tract
from Sheridan Drive is unimpaired.


-15-
Bedrock lies in +he range of 4 +o 25 fee+ below +he surface. Soils consis+ of a varie+y of clay, sandy clay, and silts, which should pose few problems for the developer.
See Section "Struc+ure/SoiIs", for more de+ailed data.
Ut iIities
Pub lie:
All public utilities are available to the area. Sanitary sewage can be discharged through an existing 10 Inch facility In Belvoir Road into the Town of Amherst Sanitary Sewer District No. 16 plant. This facility has been extended southerly along International Drive.
Public water is available from a recently constructed 16 inch watermain along the south side of Sheridan Drive. An 8 inch line extension of this also has been built in International Drive.
Private:
Electric power Is available through the existing facilities of the Niagara Mohawk Power Corporation. National Fuel Gas Corpora+ion has facilities that make natural gas available to the site.
Roads and Traffic
The subject site abuts approximately 1300 feet of Sheridan Drive, as shown on the location map. Sheridan Drive is a four land State main+ained roadway, which provides excellen+ eas+ and wes+ accessibility and exposure to the property. About 1280 feet to the west is Evans Stree+, a north/south local road which in+ersects with Sheridan and continues northward as Hopkins Road. This intersection is currently being Improved by the State, which should do much to reduce traffic congestion. In addition, Youngs Road, ano+her north/south local road to the east of +he site has recently been ex+ended. 1 + Is anticipated +h!s will relieve much of +he traffic on Evans S+reet.

Internally, the Farber tract will be connected to the Jacobs tract to the wes+ as Essjay Road by a road parallel +o and about 1100 fee+ sou+h of Sheridan Drive. 1 + will also tie into Evans Stree+ by means of roads within the Jacobs tract. I nternationaI Drive has already been buil + as a four land divided entrance at i+s intersection with Sheridan Drive. It should also be noted that none of the commercial traffic generated on the site will pass through any existing residen+ial areas.

Drainage
Storm water re+ention Is necessary. A drainage plan has been developed for the area by what Is known as the Hydrograph me+hod as outlined in a Storm Drainage Design Manual prepared by the Erie-Niagara County Planning Board. The allowable ou+flow is the amount of wa+er +hat would leave +he undeveloped area during a storm that occurs once in ten years. Detention ponds are based upon tha+ quantity of water that would be genera+ed In +he area after it is developed during a storm that occurs once in 25 years.
The topography of the land Is a uniform slope to the north with a difference in elevation of about nine feet. Because of this, individual on site basins will continue to be used for the remaining 5.84 acres of land east of International Drive. The remaining property west of the road will be served by four re+ention basins along the wes+ property line. These will be at different elevations in order to conform with the slope of the land. All basins will discharge into Town Ditch No. 10, which provided the original drainage, and were approved by the Town of Amherst.

PopuI at ion
The proposed development itself represen+s growth in the Town of Amherst. in +he shor+ +erm i+ will bring in workers who may or may no+ already reside in the town +oge+her w!+h new residents in +he dwellings. Over the long term this development should induce further new growth in the general area.
Additional populations are projected below. Residential residents are based upon 3.5 persons per dwelling unit, office at 250 square feet per employee, and retail stores at 500 square feet per empIoyee.
Residential Off i ces Bank RetaiI

390.000 sq. ft. 3600 sq. ft.
45.000 sq. ft.
546 residents 1560 employees 15 employees 90 employees
Residents will consume about 100 gallons of water per day, and discharge a similar amount +o the sanitary sewer daily. Employees in the office
facilities or retail s+ores contribute about 25 gallons per day. Based on these parameters, wa+er consumption and sewage discharge should be:
Residential 546 residents at 100 54,600 gals, per
day
Commercial 1665 employees at 25 41 ,625 gals, per
day
Total 96,225 gals, per
day
Say 100,000 gallons of wa+er and sewage.
A ten inch sewerline runs north from the property into the Town of Amherst Sewer District No. 16 treatment plant. This line has a theoretical capacity of about 710,000 gallons per day, wi+h only a small flow at present. Obviously the impact on the sanitary sewer system is small.
A new 16 Inch waterline crosses the subject property at Sheridan Drive, and is fully capable of supplying ample water to the si+e, without creating any supply problems elsewhere.


-19-
Traff1c
According to a traffic study made in 1977 by the Town of Amherst, the average daily traffic on Sheridan Drive Is about 22,000 vehicles per day, and about 12,000 vehicles per day on Evans S+ree+. The development obviously will Increase the traffic
flow, which is estimated as follows:
i Land Use S i ze Park i ng Ratio Average Turnover Traffic Generation
1 Reta i1 1 45,000 5.5/1000 10 2500
V Bank 3,600 10/1000 15 540

Residential
156 Units 2/unit 4 1248
Approximate!y 10,500
cars per day 10,528

A basic issue that will ease the traffic inflow to and from Sheridan Drive at its intersection with Internation Drive is an alternate si+e access in addition to the main entrance. The best solution is to secure a right of way in connection wi+h the Jacobs property west to Evans Street, which has been incorporated in the overall plan. The recently constructed Youngs Road extension to the west of the area is expected to relieve traffic on Evans Street.

Lighting should give special emphasis to natural features or accent points of pa+hway or open space.
Care should be given to locate fixtures to eliminate shadow areas or other conditions which could pose a securi+y -!'hrea+.
Amen 1 + ies:
Amenities are comforts or conveniences designed into a residential development. This can include man made recreational facilities as well as a sites preserved natural features.
-Sitting Areas
Benches in special locations with veiws or along circulation routes.
-Jogging Trails and Exercise Area
Jogging has become a national excercise pasttime. The provision of a jogging pa+h with occasional excersice areas Is an attractive amenity could be a possibility within 4'his design if integrated with the entire residential development.

From a land planning standpoint, a single community entry will make the entire communi+y more of a private court than a dangerous thoroughfare enhancing both privacy and security.
Site Lighting:
There are five basic areas within most townhouse developments that require lighting.
1. Streets
2. Courts/CIusters
3. Open Space
4. Unit Entries
5. Unit Entry Walks
With either a linear or cluster road scheme general illumination that utilizes the same type of fixture placed along collector and subcollec+or rou+es is frequently necessary. This is typically required of developments having a density below seven units per acre, where the unit or garage wall mounted lights do not adequately illuminate cour+s or parking bays.
Townhouses should also provide lighting for open systems in order to gain the maximum benefi+ from them.

-Swlmming Pool / Clubhouse
An outdoor swimming pool Is one of J'he mos+ desired amenities for *ownhouses and condominuims. It serves as a place to socialize wi^h neighbors and become a focus for open space and meeting ground for *he whole community. Since the entire residential development will involve 100 200 u n 11- s, these could be a feasible part of the design.
-Water Features
The existing Farber Lake is the best existing amenity of the site. The lake serves as a focal point, as well as a beautiful backdrop for the townhouses.
-Tennis Courts
A tennis court is a desirable amenity whose space requirements are not that demanding.
BUILDING SITE
Parking and Garages:
Good site planning and design will create a livable environment for easibly marketable townhouses.
There should be parking provided for +hree cars per unit. Individual driveways are desirable as well as individual garages which are attached to protect user from harsh winter cold and snow of New York. Attached garages also enhance security.


-23-
Addi^ional parking (guest) may be provided through two design options, on s^ree4- or off stree+. Since on street parking is fostered by streets ^ha* are wider than necessary, it is preferable *0 have narrow streets with parking bays than 4o have wide streets wi^h parallel parking.
Building / Road Relationships;
There are essentially two basic kinds of unit building and parking re I ationships, the use of each type depending on the location of open space, density, amenities, and view. These two relationships are garage court entries and green space entries. Garage court entries have guest entries and garages or parking areas on the same side of the two townhouse unit. This arrangement works well for the central units of a townhouse building. It also avoids having to bring a guest e.itry walk all the way around a building. Green space refers to a 4ownhouse uni* type whose entry is at the side opposite from the garage, parking, or access court. This building type maybe used when open space and amenities are centrally located.
Building Arrangements;
As buildings are first designed through consideration of how they will ultimately fit into the site plan, site placement must be studied in detail. Some of the factors to be considered are as follows:
The shape and scope of buildable land areas
The location of views and amenities Density to be acheived
Orientation to pedestrian and vehicular access
Character of the site's surroundings Street / Roadway:
Within actual residential areas, roads should emphasize character, safety, and convienence, not speed. These streets should signify +heir function through narrower widths and specifications not merely through signs for lower speed limits.


-24-
I
i
A roads function and environmentaI impact are based upon certain standards each of which must be considered in the design of streets for townhouses:
- Character of development Pavement widths Gradients
Edge treatments/curb types Drainage configurations Soil bearing capacities
- Right of way dimensions
The Entry Road:
The approach to a townhouse/condominiurn site is the first encounter with the development and entry placement significantly determine a communities image and visual character. Although a projec4-normally has some flexibility in locating the main road, it's final selection must first consider function and safety. Adequate site distances are the primary consideration. Locations of existing vegetation, etc. should also help to position entry and set the communities image. A well designed townhouse entry road might include earthwork, plantings and signage to create an element of surprise and openness.
For developments under fifty (50) units a single lane pavement width provides adequate access and egress. Proper turning radii are a minimum of fifteen (15) feet.

Service and Emergency Vehicles:
Fire Trucks:
Fire equipment turning radii requirements must be accommodated In ownhouse site planning. Fire engines must go directly to an alarm by the quickest most efficient route.
The high cost of very large fire trucks, their frequently limited maneuverability and high maintenance costs have accelerated the trend toward use of smaller vehicles with smaller turning radii. This is fortunately happening at a time of widespread popularity of the mini neighborhood and the cost efficiency of smaller pavemen+ diameters.
A 70 foot turn around is adequate according to actual turning tests of a typical suburban community pump.
Trash Col lection:
Depending on the make and model, trash and refuse collection, truck may require turning radii of 55 to 57 feet.
For townhouses at grade rather than cen+ralized units, individual garbage cans may be kept in garages or in fence extension enclosures.
Snow Plowing:
Plow mobilization within any size turnaround or col de sac is essent i a I.

7. THE USER
TYPES
The potential users of this townhouse development have been identified by a market study as "Amherst's Existing Retirees and Wealthy Professionals".
In a development report it has been stated tha+ the project shalI be designed as "empty nester luxury housing".
The users can be separated into two groups; one identified as "Mature Families" consisting of married couples where the heads of the household are 35 years or older and having one or more children still living at home; the o+her identified as "Adult Families" consisting of a married couple where the heads of the family are 35 years or older and having no children living at home.

RECOMMENDATIONS
With the interests of the individual in mind, -l-he factors of livibility, including function, safety, privacy security, identity and social interaction, are central to a carefully design, environmentally sound townhouse project.


-28-
Function Safety:
A townhouse community must basically provide shelter in a functional and efficient manner, being organized, understandable, reasonably accessible and safe. Generally these goals are attained by combining compatible community elements and separating conflicting factors. For instance a member of large windows oriented to Farber Lake take advantage of compatible element thus enhancing livibility. Separation of roads from walkways enhances safety. Garbage/trash storage separated from the entries of the home again designs function and livibility into the residential surrounding.
Privacy and Security:
People need the option of controlling their contact with other activities and people at certain times. Besides visual contact, this privacy should Include, as much as possible, control over noises lights, and odors. Private areas within the confines of a home, privacy from neighbors sharing a common wall and private outdoor spaces are vital.
Security is a provision for defense agains^ intruders or strangers that violate a persons privacy.
Separated, private home entries and careful window placement play a significant role in designing privacy in+o a housing unit.


-29-
Identity and Character:
People express their individuality through the ownership of distinctive and unique property. Their homes and surroundings play a central role in this image setting function. A carefully designed community entrance as well as forceful architecture and created si+e features add special character and identity. Also to be considered is the existing character of the village of WiI IiamsviIle. The colonial forms, styles, and details of many of the turn of the century homes and commercial buildings offer a rich context within which one must design carefully.
Community and Interaction:
In a townhouse community interaction need not and should not be forced. As mentioned previously, there should be provisions for privacy. However, those convenient opportunities for social contact that are planned and designed into the community will be recognized and used as desired.
Also, within the home itself a provision for social interaction should be made by designing a "hearth" dining room, country kitchen or family room. The "hearth" or focal point should be planned for maximum family/guest interaction.
View:
The site offers a very aesthetic setting, the main focal point being Farber Lake with the escarsmen'* beyond and with mature trees along it's northern shore.
Orientation to the lake is desirable for as many townhouses as possible. Units unable to front the Lake should be compensated by landscaping or orientation to a pool, common garden, or other amenity.
Market Study:
A market study made of the user groups identified as "Mature Families" and "Adult Families" received the following responses relevant to a townhouse design.

8. ENERGY CONSIDERATIONS AND DATA
Townhouses have an advantage over other forms of housing when It comes to energy conservation. The attached units provide insula+ion on one or more sides. With good climatic planning and design and flexible zoning and subdivision regulations entire buildings consisting of many homes may be oriented to incorporate passive solar energy techniques. This is equally true of proper wind orientation to reduce the negative effects of cold winter winds and to take advantage of the cooling summer breezes.
However, there are problems The ideal of having maximum southern unit exposure cannot be fully acheived when the long axis of the unit faces east west or when the southern facing wall is all or partly shaded by other buildings. Solutions to these problems requires careful consideration, particularly for the trade-offs between passive energy conservations and other design criteria.
One economical and operational opportunity for +he incorporation of active solar is that collection and storage facilities may be readily showed and need not be related to individual units. These collectors could be incorporated unobtrusively in common areas (hillside or berm) or on structures (common garages).


-33-
The location of Amherst, New York and the climate relevent to it will present a real challenge. It does not lend itself easily to passive or active solar design because of it's lower percentage of available sunshine and radiation. However, many techniques may bq incorporated if designed thoughtfully with careful calculations of each system.

NARRATIVE CLIMATOLOGICAL SUMMARY
For nearly 75 years the National Weather Service Office at Buffalo was located downtown overlooking the waterfront. Instruments were exposed high above the ground level. On July 1, 1543, the office was moved to the Buffalo Airpor^. Roof exposures were maintained generally un^il August 1961 when radically lower levels were prescribed to meet aviation requirements. Vertical variability of many weather elements is much more pronounced than is the horizontal; hence, with the establishment of "ground" level exposures, discontinuity in the record has occurred.
The surrounding county is comparatively low and level to the wes-1-, gently rolling to the east and south, rising to pronounced hills within 12 to 18 miles, and to 1,000 feet above the level of Lake Erie at a point some 35 miles south-southeast of the City.
At the present location an escarpment of 50 to 100 feet lies east-west 1-1/2 miles to the north. The eastern end of Lake Erie is now nine miles to the west-southwest, while Lake Ontario lies 25 miles to the north, the two being connected by the Niagara River, which flows north-northwestward from the end of Lake Erie.
Buffalo is located near the mean position of the polar front. Its weather is varied and changeable, characteristic of the latitude. Wide seasonal swings of temperature from hot to cold are tempered appreciably by the proximity of Lakes Erie and Ontario. Lake Erie lies to the southwest, the direction of the prevailing wind. Wind flow throughout the year is somewhat higher due to this exposure. The vigorous interplay of warm and cold air masses during the winter and early spring months causes one or more windstorms. Precipitation is moderate and fairly evenly divided throughout the twelve months.
The spring season is cloudy and cooler than points not affected by the cold lake. Vegetation is retarded, a fact hat protects it from late spring frosts. With heavy winter ice accumulations in the lake, typical spring conditions are delayed until late May or early June.

Summer comes suddenly in mid-June. Lake breezes temper the extreme heat of the summer season. Temperatures 90 and above are infrequent. There is more summer sunshine here *han in any o+her section of the state. Due to the stabilizing effects of Lake Erie, thunderstorms are relatively infrequent. Most of them are caused by frontal action. To the north and sou^h of Ihe City thunderstorms occur more often.
Autumn has long, dry periods and is frost free usually until mid-October. Cloudiness increases in November, continuing mostly cloudy throughout the winter and early spring. Snow flurries off the lake begin in mid-November or early December. Outbreaks of arctic air In December an on through the winter months produce locally heavy snowfalls from the lake. At the same time, temperatures of well below zero over Canada and the midwest are raised 10 to 30 in crossing the lakes. Only on rare occasions do polar air masses drip southward from eastern Hudson Bay across Lake Ontario wi+hout appreciable warming.

Average air temperature conditions identify this region as severely cold and cool most of the year, with only brief seasonal comfort and minimal warm summer periods. It is not unusual for extreme winter temperatures to plummet considerably below zero degrees, often for days and weeks at a time, with snow reaching phenomenal depths in some areas. Summers are mildly comfortable, with cool mornings, warm afternoons, and occasional periods of extreme heat that are broken by heat storms and rainfall. Annual temperature extremes, not shown in the graph, often reach over 120 degrees, making the region one of the most rugged areas of the United States.

AIA RECOMMENDATIONS:
1. Most Important keep heat In and cold temperatures out.
Building homes t'oge^her to share hea^, sluing Into a hill or berming, combined with compact forms and well insulated construction, promises maximum energy savings.
2. Avoid the infiltration and corrective heat losses caused by cold winds.
Plant evergreens, build fences or provide other wind protection to prevent heat loss. Long sloping roofs can lift chilling winds over a hours. Protect en+ries and make use of an air lock entry to stop cold air from rushing through the house.
3. Let the Sunshine in.
Use full southern exposure for living and sleeping rooms. Windows and skylights can face winter sun but should still be well Insulated against heat loss during non sunshine hours. Add storage mass for day and night passive solar heating.
4. Flatten day to night temperature swings when Its too hot for comfort.
Block the sun's energy. Use reflective roof surfaces, vented attics, and shading devices to protect windows and walls. Use decidcious trees to provide cooling shade especially on outdoor living areas.
5. Allow for Natural Ventilation.
Capture summer breezes and allow them to flow through the home for natural cooling.

9. STRUCTURE / SOILS
An advance soil survey done by the USDA Soil Conservation service identified the soil makeup of the site as an ODESSA SILT LOAM. I4- is defined as deep nearly level, somewhat poorly drained soil with fine-textured subsoil formed in reddish colored calcareous glacial lake clay and sil+ deposits. Permeability is slow. A temporary wa+er table comes within 12 18 inches of the surface during part of the year.
Soil CharacterIstics:
Depth to bedrock four foot +
Soli drainage-fair, free water is at one to four foot depths for short periods in the Springs, dropping to greater depths In the late Spring.
Soil Permeability poor 1.0 to .05 inches per hour.
Soli foundation quality poor has inability *o suppor+ great loads and the sides of cuts and trenches will have a tendency to slough-in.
Suitability as Sources of:
- Topsoi1 fair
- Sand unsuitable -Fill fair titter sjpil
Homesites with basements severe-- temporary wetness and soil instability which can result In a wet basement and settling or cracking of wallsand floors if not corrected. Principal soil problems -slowly permeable, seasonal wetness.
Underground utilities installation moderate. Principal soil problem, seasonal wetness. Installing the pipelines during the summer could overcome some of the soil wetness problems.

FI RE-SAFETY REQUIREMENTS PREVENTION OF EXTERIOR FIRE SPREAD General Requirements;
In order to retard the spread of fire, dwellings and accessory sturctures shall be loca+ed and constructed so that the distance between buildings and the fire resistance of exterior walls and of roof coverings are commensurate with the fire hazard involved.
Party WaI Is:
Where buildings are joined at a common lot line, such buildings shall be separated by party walls in conformity with the requirements set forth in this section.
Openings shall not be permitted in party walls. Construction:
Party walls shall form a continuous fire and smoke barrier beetween adjoining buildings from foundations to or through the roof, and in the event of removal or collapse of construction on one side shall not endanger the support of construction on the opposite side, and shall be capable of serving as exterior walls.
Party walls shall be constructed of noncombustible materials and shall extend not less than six (6) inches above roofs of combustible construction. When a roof is of noncombustible construction for a distance of at least 18 inches on each side of the wall, a party wall may terminate at the underside of the roof providing the junction of the wall and roof is made smoke+Ight.


-62-
Party walls shall be made smoketlght at their junction with exterior walls and the exterior wall shall be protected with noncombustible construction for a distance of at least eighteen (18) Inches on each side of the party wall. In lieu of such protection at the end of party walls in type five (5) construction, the party wall shall project through the exterior wall at least six (6) inches.
Where combustible members, such as joists and beams, are framed into party walls, such combustible members shall no+ extend through the wall but shall have at least four (4) inches of solid noncombustible material below and at the sides and ends of such members.
Fire Resistant;
The fire-resistance rating of party walls between one-story one- and two-family dwellings without a basement shall be at least one (1) hour.
The fire-resistance rating of party walls between one- and two-family dwellings shall be at least two (2) hours, except as set forth in paragraph a of this section.
The fIre-resistance ratings of party walls between one- and two-family dwellings and buildings con+aining nonresidential occupancies of low, moderate or high hazard classification shall be at least 2, 3 or 4 hours respectively.


-63-
Enclosure of Exists and Stairways:
Exits, including stairways and passageways forming a part thereof, serving in common *wo dwelling units or passing through or adjoining another dwelling or any occupancy other Ahan residential shall be separated therefrom by a fire separation having a fire-resistance rating of at least 3/4 hour.
ENERGY CODES
Acceptable Practice Method:
The Acceptable Practice Me+hod of the Energy Code provides the easiest method of determining compliance with the insulation requirements for one and two family homes. This method, which is a prescriptive approach, establishes minimum insulation values for various parts of the envelope.
The determination of these minimum insulation values in each area of the State is based upon the number of Degree Days for each county. Thus, these values are more stringent for areas such as the Northern Adirondacks.
This section graphically describes how these minimum insulation values apply to the various elements of one and two family homes. In cases where an element of the building envelope essentially consists of one material, such as concrete floor slab, the required R value of insulation is given. In cases where several materials make up the building envelope, such as an exterior framed wall, the R values of all materials and air spaces are combined and the required U value is given.
Use of the Acceptable Practice Method for determining compliance does not require extensive calculations. However, the Accep+able Practice Method is and a Il-or-none proof. Th i s means +hat all applicable par+s of the building envelope mus^ meet the minimum insulation values of the Energy Code as described in order to be in compliance.


-64-
L imjta-1'ions on Glass Area:
The Acceptable Practice Method establishes shortcuts *0 the calculations required for demonstratIon of compliance wi^h the Insula+Ion requirements of the Energy Code. These calculation shortcuts are possible only as long as the glass area of the house does not exceed certain limits. The Energy Code does not limit +he amount of glass that may be used in a house; the glass area is only limited when the Acceptable Practice Method is used.
The use of these glass area limits to es+ablish prescriptive minimum insulation values varies by Degree Day Zone, as described in the following table:
* If the glass area exceeds these values, Energy Code compliance must be demonstrated through the use of Part 4 Design by Component Performance.
If the glass area is below the limits outlined, the Acceptable Practice Method can be used and a I I sections of this Workbook are applicable for determ In i ng comp Ii ance.

HVAC SYSTEM EFFICIENCY: ELECTRICALLY OPERATED
The Energy Efficiency Rating (EER) is the commonly used rating measure for.the efficiency of cooling systems. EER is the ratio of cooling capacity (in Btu/hr) to input energy (expressed in watts). In other words--how much energy input is required to produce the cooled air.

EER and COP both measure efficiency, the basic difference being that EER measures input in watts and output in Btu/hr and COP measures both input and output in Btu's. For both EER and COP, the higher the number, the higher the efficiency.
The Energy Code requires that electrically operated HVAC systems for heating and cooling meet minimum efficiency standards.

HVAC equipment
HVAC HEATING EQUIPMENTGAS OR OIL FIRED
All gas and oil-fired equipment must meet certain standards for minimum combustion efficiency. This combustion efficiency represents the percentage of net usable heat resulting from the combustion process. Stack heat losses and the loss of heat due to combustion of hydrogen in the fuel are subtracted from the overall efficiency in order to determine this combustion efficiency.
The Energy Code requires a minimum combustion efficiency of 75% for gas and oil-fired combustion equipment. Manufacturer's information should indicate the combustion efficiency at maximum rated output for use in selecting and comparing equipment.
Proper and Routine Maintenance is necessary to maintain a high combustion efficiency. A homeowner should have the unit checked at least once each year before the heating season begins.

code compliance thermostats
For one and two-family dwellings, at least one thermostat must be provided for each HVAC system or each dwelling unit.
Each zone or story also must have either a manual or automatic means to restrict or shut-off the heating or cooling. This may be done through a thermostat, by a damper at the register or by a control valve at the unit.

THERMOSTATS
A therrrostat provides the means to control the heating and cooling of the building. The temperature scale on a thermostat must have at least the minimum range of available settings described below. The temperature scale may also have higher or lower settings as long as the required minimum range is included. The purpose of this requirement is to assure that the building temperatures may be adjusted to suit individual needs.

code compliance water heaters
The Energy Code requires minimum operating efficiencies for gas and oil-fired water heaters. Limitations are also set on allowable standby losses.
ELECTRIC
standby loss not to exceed 4 watt hrs/hr/ sf. (Efficiencies for electric heaters are usually near 100%.)
GAS
standby loss not to exceed 2.3 + 67/volume of tank in gallons.
75% minimum recovery efficiency.
OIL
standby loss not to exceed 2.3 + 67/volume of tank in gallons.
80%'minimum combustion efficiency.
STANDBY LOSSES
As the heater sits with a full load of hot water, heat loss occurs through the jacket or shell of the water heater. These standby losses can be limited by the type of construction and amount of insulation in the jacket.
The Energy Code limits these standby losses. For instance, on a 30 gallon gas water heater, the allowable standby losses would be limited to S = 2.3 + 67/30 gallons or 2.8%, which means that the heat loss/hr cannot be more than 2.8% of the total amount of stored heat. Models that specify meeting the requirements contained in Standard ASHRAE 90-75 will meet the Energy Code standby loss requirement.
COMBINATION SERVICE WATER HEATING/SPACE HEATING BOILERS
Some space heating boilers have a separate heating unit to supply domestic hot water on demand. Often called tankless coils, water is sent through the coil, heated by the space heating boiler and used on demand. To accomplish this domestic water heating, it is necessary for the boiler to be on, even during the summer. The standby loss which occurs from this situation is limited to that standby loss which must be calculated through a specific formula outlined in the Energy Code. It may be difficult for many smaller residential size combination water heating/space heating boilers to meet this requirement, so the specifications should be checked prior to equipment selection.
