ARCHITECTURE 2840: SUSTAINABLE DESIGN INTIATIVES 2012 COLLEGE OF DUPAGE
Use: Any exterior wall where drywall or exterior siding has been removed. Floors over unconditioned spaces. Rim joist or anyplace the structure meets the foundation. In attic where interior walls meet attic space.
Brand: Eco Tec Insulation uses Icynene spray foam which are PBDE-free. Made with castor oil rather than petroleum-based polyol.
Blown insulation
Use: Un-insulated attics or adding to existing attic insulation.

RESEARCH TOPIC: HOUSE WRAP
HOUSE WRAP
Housewrap functions as a weather-resistant barrier, preventing water from getting into the walls while allowing water vapor to pass to the exterior. If moisture from either direction is allowed to build up within stud or cavity walls, mold and rot can set in and the insulation will lose its R-value due to heat-conducting moisture.
House wrap will also serve as an air barrier if it is sealed carefully at seams.

RESEARCH TOPIC: SIDING
SIDING
Three types of siding were researched for rehab applications; vinyl, insulated vinyl, and fiber cement.
New siding not only enhances the home appearance, but also provides a maintenance free exterior.
Of all the brands available, CertainTeed was identified as an industry leader in siding.
Manufactured responsibly
Produced, shipped and installed using minimal valuable resources.
Made from recycled materials and recyclable.
Able to meet LEED and NAHB guidelines for sustainability.
Almost 100% of raw material inputs are used in the manufacturing process of CertainTeed’s Vinyl Siding, practically eliminating landfill waste from manufacturing these products.

RESEARCH TOPIC: DRYWALLS
MOISTURE-RESISTANT GYPSUM BOARD
GOLD BOND XP GYPSUM BOARD
100% recycled paper surfaces.
Greenguard Children and School certified.
Heavy mold, fire, mildew and moisture resistant.
Can be used as tile backer in certain dry areas.
National Gypsum Company used to produce greenboard for high moisture areas, but because of the versatility and performance of XP gypsum board, they stopped the production of greenboard in 2006.

RESEARCH TOPIC: Cabinets & Countertops
Cabinets & Countertops
The kitchen is often the most useful part of the remodel and can really help to enhance the home. Because of this, making it an efficient space, easy to clean and maintain as well as a safe environment to be and prepare food in is an extremely important part of the rehab.

RESEARCH TOPIC: Countertops
Laminate
Laminate still seems to be used as the “best practice” available when it comes to countertops. Its cost effective, sufficiently durable, attractive, easy to clean and readily available.
Generally not environmentally friendly, especially through production.
Formaldehyde adhesives and finishes are often still included in finished product manufacturing process.

RESEARCH TOPIC: Countertops
Concrete/Cement/Resin
Depending on the skill level of the volunteers or other experienced crew members, concrete, cement and resin countertops have become a popular sustainable product. For added sustainable purposes, as well as appearance, broken, recycled glass has been mixed into countertops. (This often ends up with a finished look somewhat resembling expensive quartz countertop.)

RESEARCH TOPIC: Countertops
Bamboo
End grain bamboo countertops have become another sustainable option for countertops.
The most important aspect to the sustainability with this type of surface is the way it is assembled, specifically the bonding adhesive used to assemble it. Like all other adhesives, it is best as a formaldehyde-free product.
This type can be cut with any wood-working tools, proving a volunteer friendly material.

RESEARCH TOPIC: LUMBER
FSC LUMBER
•Lumber should be produced in an environmentally responsible manner.
PRESSURE TREATED LUMBER
•The greenest treated-wood option for lumber today involves a sodium silicate and heat treatment. The resulting material is nontoxic and highly resistant to insects and decay.

RESEARCH TOPIC: LUMBER
SUMMARY
•The Forest Stewardship Council (FSC) is the only certification system to offer genuine certainty about responsible forest management.
•Do not let retailers talk you into buying any other certified product.
•There is a FSC product database where you can search for manufacturers and distributors, but not retailers. [www.fsc-info.org]
•During the ACQ and CA treating process, wood becomes saturated with a chemical solution carried in water. After this process, the wood takes several months to dry depending on the climate region.
•Some treated wood has large amounts of copper, standard steel fasteners will corrode up to five times faster than when used in untreated wood.

RESEARCH TOPIC: REUSE OF MATERIALS
SUMMARY
•Materials can be salvaged by the volunteers.
•Some materials may have been exposed to hazardous materials and would require an evaluation.
•Consider making a list of materials usually found in rehabs and have potential to be reused: Old doors, shelves, hardware, furniture, bricks, stones, plants, etc.

RESEARCH TOPIC: LIGHTNING
Light Bulb Selection
Incandescent bulb Wattage 60W
Total Lumens 840
Lifespan Hours 1,000
Annual Energy Cost 8.00
CFL bulb Wattage 11w
Total Lumens 770
Lifespan Hours 8,000
Annual Energy Cost 1.45
LED bulb Wattage 5W
Total Lumens 625
Lifespan Hours 50,000
Annual Energy Cost 0.40
*Energy costs are based on the standard approximation of 10p per kWh, with average usage of 4 hours per day for a modest family home with 30 light bulbs.
