BIBLIOGRAPHY

Bibliography: 32

Hey, it’s Chava. I am in my second year at Boston Architectural College as Master’s of Architecture student. I currently work in a mid-size architecture firm which services both residential and commercial clients. The firm I work for is always striving for sustainability. They bring in lecterors weekly who speak about innovate products and methods for designing enviromentaly friendly.

Aside from my profession, I enjoy cooking, fashion, traveling and reading. I’ve been to Singapore, Bali, Beijing, Hong Kong, Italy, Greece, Costa Rica, Israel and Thailand. I love exploring the different cultures, landscapes, people and architecture.

My favorite genre is memoirs followed by pyschological thrillers. It isn’t difficult for

me to finish a book in one sitting! I love shopping and try to practice sustainability in the process. I donate my old clothing and purchase sustainable materials.

I cut my meat consumption to once a week. I eat salads daily and dairy products often. I find many recipes online and like experimenting with ingredients. Sustainibility is important to me and I practice the small measures I can to help the environment.

MY ECOLOGICAL FOOTPRINT

Self- Reflection:

United States average is 5.0 earths, which means the average American is living as if we have the resources of five earths. My average is 4.6 which is just under average. It is frightening to think of the toll we take on earth by going about our daily lives. I would like to adjust my diet so that I can live more sustainability. Measures include, eating less animal products, buying more organic, unprocessed foods and

consuming more renewable products such as fruits and vegetables.

THE SIX

Building Information

ARCHITECT & DESIGN TEAM: BROOKS + SCARPA

LOCATION: Los Angeles, California Meditarian Climate

The six is a 62-unit affordable housing project that offers a home, support services and rehabilitation for disabled veterins. The space is organizes so that the public space is emphasized to create a community environment.

The ground level contains parking, bike storage and support centers, While the second level contains a public courtyard. The uppermost level has a green roof, edible garden, public patio as well as a panoramic view of the area.

The Six is 50% more efficient than the convential building design. Many strategies were emplemented into the building design to ensure energy effiencies in all construction and occupancy phases of the building.

Strategies include: Shaping and orienting the building for exposure to pervailing winds. Windows were designed to increase daylighting. The south facing windows are shaded while west glazing is minimized. Water is conserved with using low flow fixtures and incorporating storm water management. The building’s interior is shaped to maxamize daylight and enhance natural air flow.

INTEGRATED DESIGN SKETCH

INTEGRATED DESIGN

Key aspects of the intergrated design include a water system where the water is consumed and collected from a green roof and then stored in underground basin. Additionally, the building is perforated to allow breeze throughout the building. The roof protects solar gain while also carrying solar panels which stores heat for hot water and building energy.

BUILDING ELEVATIONS

The Six was orientated in order to maxamize efficiency and sustainability. The south of the building is shaded while glazing on the west in minimized.

WIND VELOCITY CHART

Architect’s took advantage of the local wind velocity to use as passive ventilation. They surveyed the wind on site and oriented the building to provide maximum wind penetration. Additionally, the building is punctured to allow airflow infiltration.

RADIATION RANGE CHART

The Six was built to absorb maximum comfortable solar penetration. The solar panels on the roof rely on the radiation as well. The panels heat the building’s water, thus the water relies on radiation as well.

SUNSHADING CHART

Building’s south side windows are all shaded. As the chart depicts it can get really sunny and shades are need during mid noon hours.

PHYSCHOMETRIC CHART

Design Strategies

Designing for 100% comfortability. The top three strategies from the pyschometric chart (see page 14) are internal heat gain (44.6%), sun shading of windows (20.8%) and passive solar direct gain (22%). Other significant strategies include high thermal mass night flushed(15%), heating (17.6%), natural ventilation cooling (7.9%).

INTERNAL HEAT GAIN

The Six was designed for maximum comfortable solar penetration which is a big factor in its heat gain. Solar panels heat the building’s water.

SUN SHADING OF WINDOWS

The south windows are all shaded, while glazing on the west side is minimized. (See page 12.)

PASSIVE SOLAR DIRECT GAIN

The interior of The Six was planned and shapped to increase daylight and natural air distribution. Additionally, an array of solar panels take up 1/3 of the roof and provide energy for heating the building’s water. (See page 11.)

HIGH THERMAL MASS NIGHT FLUSHED

The building’s circulation spaces is made with FSC-certified IPE wood screen shades for air circulation.

HEATING

The building’s perimeter wall are filled with blown-in recycled cellulose insulation. The insulation, reduces thermal bridging and infilteration.

NATURAL VENTILATION COOLING

The six was located and oriented for maximum expose to pervailing winds. The building was shapped to cause buoyancy for natural ventilation. Furthermore, the interior was shapped to increase natural ventilation throughout the building. Windows are designed and placed to maximize natural ventilation. (See page 10.)

DESIGNING FOR SUSTAINABILITY

NATURAL VENTILATION AND DAYLIGHT

The images below display the building design incorporating the daylight and natural air ventilation. The building was built with white concrete, to reflect light and thus increase daylight in the building. Image 3 shows the sun reflecting onto the white blocks on the roof which then gets dispersed into the building. Images 1 and 2 depict the building opening which allows for natural ventilation and daylighting to disperse throughout the building. Image

4, once again illustrates the manipultion of space to maximize the natural ventilation and sunlight. Additionally, it shows the community layout and program of the building.

COTE TOP TEN MEASURES

KEY OBJECTIVES

The Six is designed for community as its main concept is supporting diabled veterans. Included in this is its ground floor with space dedicated for bike racks and parking spaces. Additionally, the Six incorporated many water conserving strategies. The green roof collects water from landscape and there is an underwater basin storing stormwater.

Plants were chosen based on water efficiency. Lastly, the architect managed to cut the cost of construction from the average $300/SF down to $254/SF. They reduced the cost by using a wood-framed prefam system of roof and wall truss framing, and design build floors with performance specification.

RAINWATER CALCULATIONS

Rainwater calculation would be part of the intial site surveying. Important building details such as foundation type relies on the permeability of the soil and local rainful. Additionally, sustainablity measures depend heavily on rainwater for building systems and greywater use.

FIXTURE CALCULATIONS

Fixture calculations allow building owners to see how much water will be used throughout their building. This step would be approached as the plumbing of the building is being set up. If there is a fixture calculation to look out, the owner can see how much water he will save by taking a water efficient approach and using low flow fixtures.

WINDOW-WALL RATIO

During the design phase, when the architect is placing windows, it is important to take note of the window-wall ratio. Optimal window-wall ratio should be 40%. A window-wall ratio too large will

make insulating the building very difficult, while a window-wall ratio too small won’t allow enough sunlight into the building.

In-Class Exercise #08a: Window Wall Ratio

1 - A building has a floor slab that is 20’ x 30’. Each exterior wall is 20’ tall. Windows comprise 25% of the walls. There are two (2) doors and each is 3’ wide by 7.5’ tall. The hip roof is 1,400 sf total. What percentage of the overall building is each component?

2 - A building with a flat roof has the elevations below. What is the WWR (Window Wall Ratio)?

Calculate for each facade and for all walls combined. We are only looking at walls in this case.

SANKEY DIAGRAM

Compared my studio museum project (120,000 SF) to the Demo Building A-structure. The museum has a 34% reduction and its at its acheivable EC target. The Demo Building has a 41% caarbon reduction and it is below its acheivable carbon.

Some ways to offset the embodied carbon is by reusing materials or using highrecycled content materials. Maxamizing structural effiecency, reduces material and thus embodied carbon. Lastly, minimizing material waste can offset embodied carbon substancially.
