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

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

Reused or salvaged materialsProducts from Habitat RestoreScrap Materials

Facilitation for sorting and reuse of scrap building material. (e.g. provide a central storage area or dedicated bins)

Advanced framing techniques are implemented that optimize material usage.

1)Single top plate walls2)19.2” or 24” OC spacing3)Right sized or insulated headers4)On –site material cut lists5)Building dimensions and layouts are designed

to reduce material cuts and waste6)Precut or preassembled components, or

panelized or precast assemblies are utilized for a minimum of 90% for ; floors, Walls, and roof

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

Certified lumber FSC, SFI, ATFS Recycled- content Building materials1) 25%-75% of the content of material is

recycled2) Siding, decking, flooring, roofing Renewable Materials/Biobased products1) Engineered wood2) Bamboo3) Cotton4) Cork5) Straw6) Natural fiber based products made from

crops (soy-based, corn-based)

Indoor Environmental QualityMinimum 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

require site application

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.

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.
