Touchstone Custom Homes is a proud Builder member of Earthcraft Virginia. Our current project in Vienna, VA is aiming for Earthcraft Gold certification and will be the first in the Vienna market.
What is Earthcraft?Developed in 1999 by the Greater Atlanta Home Builders Association and Southface, EarthCraft is the Southeast’s standard for green building, pairing building science with regional know-how. The result? Exquisitely designed and renovated homes, buildings and communities. Come explore our site, and learn about all that EarthCraft has to offer, whether you’re a building industry professional or a customer looking for a new home! EarthCraft House certifications are determined through a points-based worksheet, which allows builders to select the sustainability measures that are best suited for their project. Worksheet items address proper site planning, energy-efficient appliances and lighting, resource-efficient building materials, indoor air quality, water conservation and homebuyer education, and all are verified during site visits and inspections. EarthCraft-certified homes must also pass diagnostic tests for air infiltration and duct leakage standards, and homes certified at the gold or platinum levels must meet ENERGY STAR requirements. EarthCraft Technical Advisors provide technical assistance to the builder during the initial design review and throughout project design and construction. EarthCraft serves as a blueprint for energy, water and resource-efficient single-family homes, multifamily structures, renovation projects, community developments and light-commercial buildings. To date, more than 13,000 EarthCraft homes, multifamily units and commercial buildings have been certified.
Home Energy Rating SystemThe Home Energy Rating System (HERS) is a tool used in green building construction, as well as in home energy auditing and certification programs. It is a relative scale that measures a home’s energy efficiency and performance, as compared to other homes. The HERS Index scale ranges from zero to 150, and the lower a home’s HERS Index, the more energy efficient it is. A zero indicates ideal energy performance, while a 150 indicates poor energy performance. A typical existing home will generally achieve a HERS Index of about a 130, and a standard code-built home will achieve about a 100. EarthCraft homes must perform 15 percent better than code, obtaining a HERS Index of 85 or less. HERS ratings are highly versatile performance indicators that can be used to:
- Verify that a home meet the requirements of green building programs like LEED® for Homes and EarthCraft
- Fine-tune the projected energy performance of a building prior to construction
- Qualify buildings for ENERGY STAR certification
- Provide verification for Energy Efficient Mortgages (EEMs)
- Benchmark and enhance current building performance
