2.  Objective: after this brief you should have a better understanding of ; 1. Materials that don’t primarily affect energy efficiency 2. Environmentally friendly building methods 3. How these methods reduce landfill waste 4. Healthy indoor air quality

3.  Lot Construction  Intent- Environmental impact during construction is avoided to the extent possible; Impacts that do occur are minimized, and any significant impacts are mitigated. 1) Limits of clearing and grading are staked out 2) Top Soil is stockpiled 3) Cleared vegetation is grounded and used as silt fence

4.  Reused or salvaged materials  Products from Habitat Restore  Scrap Materials  Facilitation for sorting and reuse of scrap building material. (e.g. provide a central storage area or dedicated bins)

5.  Advanced framing techniques are implemented that optimize material usage. 1) Single top plate walls 2) 19.2” or 24” OC spacing 3) Right sized or insulated headers 4) On –site material cut lists 5) Building dimensions and layouts are designed to reduce material cuts and waste 6) Precut or preassembled components, or panelized or precast assemblies are utilized for a minimum of 90% for ; floors, Walls, and roof

6.  Resource-efficient Material are used to achieve the same end-use requirements as conventional products. 1) Lighter, thinner brick with bed depth less than 3” 2) Engineered wood or engineered steel products 3) Roof or floor trusses

7.  Certified lumber FSC, SFI, ATFS  Recycled- content Building materials 1) 25%-75% of the content of material is recycled 2) Siding, decking, flooring, roofing  Renewable Materials/Biobased products 1) Engineered wood 2) Bamboo 3) Cotton 4) Cork 5) Straw 6) Natural fiber based products made from crops (soy- based, corn-based)

8.  Indoor Environmental Quality  Minimum of 85% of wall coverings, hard surface flooring, installed carpet area, carpet cushion, and adhesive are in accordance with the emission regulations certified by a third- party program

9.  Architectural coatings  Site applied interior/exterior products are low zero or low VOC.  Adhesives are low VOC  Products are pre-finished. Don’t require site application

10.  U-Factor (Thermal Transmittance)- The coefficient of heat transmission (air to air) through a building envelope component or assembly, equal to the time rate of heat flow per unit area and unit temperature difference between the warm side and cold side air films. UF-measures how well a product prevents heat from escaping a home or building. U-Factor ratings generally fall between 0.20 and 1.20. The lower the U-Factor, the better a product is at keeping heat in. U-Factor is particularly important during the winter heating season.  Solar Heat Gain Coefficient (SHGC) The ratio of the solar heat gain entering the space through the fenestration assembly to the incident solar radiation. Solar heat gain includes directly transmitted solar heat and absorbed solar radiation that is then released into the space. Lower the number = less transmitted energy. Particularly important during summer cooling months.

11.  Visible Transmittance- measures how much light comes through a product. VT is expressed as a number between 0 and 1. Heavily tinted products have a relatively low VT.  Air Leakage-measures how much outside air comes into a home or building through a product. The lower the AL, the better a product is at keeping air out. AL is an optional rating, and manufacturers can choose not to include it on their labels.
