PROJECT DAYLIGHT

Project Daylight is a design modification that can be applied to an existing housing typology in Lawrenceville. This transformation, although shown for a specific home can be adapted to any mason’s row house to improve daylighting in the home and minimize utility costs by taking advantage of passive strategies. The implementation strategies presented are designed to provide an affordable path to the realization of renovation that can impact and revitalize the Lawrenceville area.

LAWRENCEVILLE

The Central Lawrenceville neighborhood is one of Pittsburgh’s most diverse districts. The population reflects multiple income levels, ages, races, and family structures. The built environment itself is equally dynamic with industrial areas directly next to single family houses, row homes, apartment buildings, and commercial streets. As with much of the city, the neighborhood suffered from a rapid exodus of population in the last fifty years. However, the city has recently marked it as a “hip” destination for artists and young professionals, reflected by the revitalization of Butler Street businesses and new influx of people.

HOUSING TYPOLOGY

The common features of this mason’s row type include two story constructions with an attic typically defined by a single center dormer facing the street façade.

On the other floors, three bays are defined by equally spaced windows that face the street. Many have been modified over the years. Common modifications found in Lawrenceville include an addition in the rear of one or two stories, and front porches with proper setbacks. Some owners even chose to enclose their porches for more heated indoor space. Historically, heating systems were fueled by coal, and many have a chute in front for coal deliveries.

IMPLEMENTATION

The adaptive transformation of the porch along the front façade will extend the living space and improve the overall daylighting in the house. This glass extension can utilize passive heating strategies in the winter to minimize utilities. In the summer the porch can be completely open, taking advantage of natural ventilation. Collecting rain water and adding plantings will stop flooding and cut back on water usage for irrigation. Ultimately, the approaches defined will improve the quality of life in the Central Lawrenceville neighborhood through sustainable and affordable means.

PROJECT NARRATIVE

PN1.00

POPULATION & RACE (2000, 2008)

KEY Population (2000) White

The current population that resides in Central Lawrenceville (4,654) is the largest of the three when compaired to those of Lower (2,295) and Upper Lawrenceville (2,495).

Relatively, it is nearly double that which can be found in either of the other two. Since 2000, Lawrenceville overall has experienced a significant decrease in population, the majority of which occured in Central Lawrenceville. However, when studying this drop relative to the lower and upper regions, Central Lawrence has exhibited the smallest percetage decrease over time.

African American Asian Other

Overall, studies of the racial demographics that make up Lawrenceville reveals a relatively homogeneous population that is predominately White. A smaller African American and Asian population makes up the remaining demo along with an even smaller population comprised of other ethnicities.

LOWER LAWRENCEVILLE

In comparison to the greater Lawrenceville region, Central Lawrenceville has the greatest number of people in all of the age groups except for those in their sixties to mid seventies. Out of the population of Central Lawrenceville, the majority are in their mid thirties to late fifties, with a similar percentage found to be in their early years to mid thirties, implying a family oriented population make up. Another demographic that can be found in Central Lawrenceville is the elderly, who are in their mid seveties and onwards.

BUILDING PERMIT REQUIREMENTS

Prior to the construction, enlargement, alteration, or repair of any building or structure a building permit is required. A contractor licensed by the City of Pittsburgh must make the application for building permit unless the occupier performs on his/her own one or two-family dwelling and no employees are hired.

The building permit applications must be made by the owner, contractor, or authorized agent. The process includes: zoning counter, file room, engineerâ&#x20AC;&#x2122;s counter, license and cashier counter. The following information is needed: address of the job site, ownerâ&#x20AC;&#x2122;s information, check or money order, contractor registration information, constructions plans (approved by an engineer or architect), and if occupancy permit is needed a plot plan for zoning approval is required. http://www.city.pittsburgh.pa.us/BBI/html/building_permit.html

Central Lawrenceville Topography with 5 foot contour intervals

DAYLIGHT

Because Pittsburgh is located on the windward side of the Allegheny Mountains, there is often cloud cover and many overcast days. In the winter months, only 28% to 30% of daylight hours have direct sunshine. In summer this number climbs to 55%, which is still a fairly low amount of sunshine. This brings into question the feasability of passive solar systems. [source: rssweather.com]

TOPOGRAPHY AND SLOPE

Central Lawrenceville is located on a hillside sloping northwest toward the Allegheny River. The nieghborhood itself has a fairly steep but tranversible grade, while steep slopes exist to the south and north.

The western part is located on the flat lowland adjacent to the river. The direction and grade of slope can affect the exposure to sunlight of buildings, especially that of the Hill District to the south. Also, runoff patterns are directed down the north-south streets due to the slope.

SUN ACCESS

The primary case study house is facing southest. With no houses on the opposite side of the street, this means excellent access to sunlight during the morning hours year-round for rooms in the front portion of the house.

These spaces already have large windows that are acceptable for solar gain the winter, but could present a problem of overheating during the summer months.

The northeast facade of the house recieves no direct sunlight but also has no fenestration. This facade is ideal for allowing indirect light in the summer months while contributing little to overall heat gain. Currently, this strategy is not being utilized.

PREVAILING WIND PATTERNS ON PRIMARY HOUSE

WIND PATTERNS

Winds are primarily from the southwest during summer and winter months but shift more westerly during mid spring and autumn. Average wind speeds vary from around 10 -12 knots in winter to 6 - 8 knots during the summer. Local conditions may modify the prevailing wind patterns and proximity to built structures, open spaces, and orientation have an effect on inidividual structures. A steep hill lies to the southwest of Lawrenceville, directing winds to the west and south. Strongest wind patterns come from the riverfront to the northwest.

WIND ROSES FOR FOUR SIGNIFICANT MONTHS

(METERS PER SECOND)

October

The location of the primary case study house on a relatively isolated hillside makes it highly susceptible to wind, especially southwest winds that come directly up the street. This can affect the required heating of the house in winter, but is desirable in summer for passive cooling.

TEMPERATURE Pittsburgh is a four season climate with warm summers and cold winters. Average temperature in winter ranges from 19 to 35 degrees Fahrenheit, while summer averages 62 to 82 degrees Fahrenheit. The climate is thus heating-based, with 5968 heating degree days versus 654 cooling degree days. A heating system is required in all homes, but cooling may be completed passively to avoid constructing cooling systems. http://www.rssweather.com

PRECIPITATION Annual precipitation is 37.85 inches, falling fairly evenly across the year but slightly more in spring and less in fall. Pittsburgh also recieves around 15 inches of snow per season. Precipitation drains northwest to the Allegheny River. The slope of most of the neighborhood toward this direction as well as proximity to green areas such as the cemeteries and parks allows for several areas for water retention and drainage control. Water falling on the roof can also be collected for grey water usage in the home, further reducing runoff. http://www.rssweather.com

PS2.03

LOCATIONS OF HOUSING TYPOLOGY The focused typology is a two-story, single unit house with three bays of windows and a dormer on the street-facing facade. Some variations include balcony, sizes and position of windows, setback, addition of the back of the house, etc. The houses are scattered across ten streets. Different positions dictate how the owner adept their houses. Because Upper Lawrenceville is centered on industry, the majority of this housing typology can be found in Lower and Central Lawrenceville The primary materials used in this typology are bricks and shingles with various exterior finishing. The prices of the houses are acquired from the Allegheny County tax assessment web site. Prices may not match the present day value since appraisals were taken place in the 1900â&#x20AC;&#x2122;s.

Number twenty is the primary house with east-west axis. Number six is the secondary house with north-south axis. Both houses are detached masons rowhouse with a vacent lot on one side.

Side setback and space utilization A 10 foot side setback in between the house and its neighbor has been partitioned out and paved with the clear intention for it to be used as a carport. However, because the street is more remote and does not see much traffic, people have come to park their cars along the street rather than in the narrow spaces in bvetween each house to allow for easier access. The space has been fenced off and utility lines and air-conditioning units have been allowed to protrude out into the space that once would have been reserved for the automobile.

Side setback and utilization As a detached, single-unit typology, the house has a narrow 5 foot clearance between it and the structure on its adjacent lot. Because of the limited width and accessibility of the space, this alley is rarely inhabited. Instead, it is utilized mainly as a service corridor along which to run utility lines and store garbage so as to keep them hidden when viewed from a street front perspective.

Front and Rear setback and utilization The house is set 10 feet back from the side walk and 20 feet from its neighboring look in the back.

This leaves a decent amount of space to be utilized in both the front and back yards. The front yard is currently being utilized as a garden space, which not only provides shade but also serves to screen the front of the house, creating a good amount of privacy on an otherwise densely packed residential block.

The code requires a 15 foot front yard setback, however only a 2 foot setback exists for the current housing footprint. The side setback is also incompliant with the 5 foot minimum setback requirement as stipulated by land-use code.

Instead the house sits right along the lot boundaries of the vacant piece of city owned land.

EXISTING CONDITIONS With a double brick construction, the building envelope seems stable and sturdy despite its age. The owner of the house replaced the old windows with new double glazed windows within the past ten years, while other openings have been covered up with brick. There are cracks between the old and newly filled in brick. The gutters need to be redirected; currently they extend directly onto the lawn.

Newly installed double glazed windows; no

Lose shingles overhead

The interior of the house has been renovated by the owner and does not require further rennovation. The owner mentioned that the chimney leaks inside the house, which needs to be fixed. Originally there were fire places in every room, but now all of them are blocked from inside.

The porch was constructed by the father of the resident a few decades ago. Its original wood construction was later reinforced with brick. Due to years of exposure to severe weather and the elements, the porch is currently in poor condition. The wood overhead is rotting and warping, and the shingles have come loose. The porch needs to be fitted with a new roof and drainage system.

Grass exists only on the cemetary side of the house, and there are no trees around the house. There is a small stone decoration in front that requires little maintenance. The large backyard is not well maintained, and is currently being used as storage space for garbage and machinery.

However these are not the original materials, they were later added to the house.

The house structure is wood frame construction with brick exterior. The porch, which was later added is also wooden structure.

Majority of the exterior is brick.

ARC48_550 HEATING COAL

Coal Chute

One of our housing studies was constructed around 1900 and originally used coal as the main heating method. A coal chute can be seen from the porch, this was originally designed to have coal be directly transferred to the coal storage area and furnace located in the basement. Most homes that date back to this time would have used coal before updating the homes heating system.

GAS RADIATOR SYSTEM

Radiator

STEAM AND WATER Homes in the Lawrenceville area currently use a gas radiator heating system using.

Either steam (which was specifically used in house 1), or water is circulated through exposed pipes. Radiators installed in these housing typologies usually exist in front of windows to help cut the harsh cold weather air that infiltrates through windows in the winter. Steam radiators are rather energy inefficient because of the time lag between turning on the system and the arriving of steam.

Depending on when the heating system was last maintained, radiators can run at about only 40-50% efficiency. Ways to improve heat transfer throughout the room would be to place a reflector behind the radiator so the hot air reflects back into the room.

Other possibilities for heating in the Lawrenceville area would be electric baseboard heaters. Since most homes date back to the 1940â&#x20AC;&#x2122;s a central air system would not have been in place unless in a major retrofit occurred.

Radiator Reflector

COOLING AIR CONDITIONING UNIT

The main method of cooling in the residences of Lawrenceville is through the addition of a window air conditioning unit. Our first house had one placed on the second floor, the second house had two, one on the first floor and one on the second floor. Window AC units make for an easy retrofit for a home and offer the flexibility of turning on the unit when using a single room.

The front porch was originally wood but was replaced with a brick one and contains a louver system facing the vacant lot for passive ventilation control on the porch.

Heating was originally by coal furnace. The chute that used to deliver coal still exists below the front porch of the house, though no longer in use. There are two chimneys along the eastern wall of the original house and one on the west in the rear addition inferring possible location of the heating system inside. There is no cooling system, except for air conditioning units the owner placed in the windows.

The main case study house is located at 4627 Bancroft Street, near a part of Allegheny Cemetery. It is relatively isolated, at the end of a dead end street with a large vacant area directly next to it. The facade faces southeast and the primary orientation is East-West.

The house was built in 1900 and contains 6 rooms, 3 bedrooms, and 1 bath. It consists of an original house and a later extension to the rear. The original house is three stories over a basement. The third floor is within the eave of the roof with one dormer over the front. The second floor fenestration contains three windows on the street facade.

The original house was expanded at an unknown time to the rear on the first two stories and basement. The large rear extension nearly doubles the living area of the house, to 1,472 square feet. It is made entirely of brick construction, with no insulation except for panels added to the interior of some rooms. While there several windows on the two sides that would normally abut similar row house types, changes in the brick work imply windows were larger at one time, and back doors have been relocated from the side to the rear.
