2012 Earth Advantage Residential Measures Resource Guide 1.3.4 Energy Health Land Materials Water House has detached or no garage 0 2 0 0 0 Description: The garage is designed as a separate isolated structure from the house or there is is no garage built. Benefit: The garage is usually the storage place of a wide range or herbicides, pesticides, fertilizers, paints, adhesives, and petroleum products. It is also a place where internal combustion engines operate in a poorly ventilated space. The best way to prevent harmful fumes from entering the living space is to build the garage as an entirely separate structure. Verification: EA Rater will verify that the garage and house do not share a common wall, ceiling, or floor, or that there is no garage built. 1.3.5 Green Team Meeting Energy Materials Water 0 1 1 1 0 Description: Owner/Developer, Designer/Architect, General Contractor/Builder, Earth Advantage Team Member, and the following subcontractors (framing, electrical, HVAC, insulation, landscaper) participate in a meeting. This meeting must take place before construction begins. At this meeting the builder can emphasize the goals of the project and new building details, and give the subcontractors drawings and instructions on how to accomplish their roles in the project. This meeting will go help people understand their roles and responsibilities. Make sure that the subcontractors are aware that the Earth Advantage team will be conducting inspections. Note that both the ductwork and the building envelope will be tested for air tightness. It may be necessary, especially for the first certified home, to hold additional training sessions with key subcontractors. One meeting per project is required for points. A project could be defined as a custom or development. That is, for production builders this meeting will need to take place before the start of each new subdivision. Additional charges may apply. Health Land Benefit: A meeting where the Green Team gather to review the project goals and specific green building measures helps ensure success of the project. Verification: EA Rater is one of the members of the Green Team and will be able to award this measure once the meeting has taken place. 1.3.6 Moisture Modeling: WUFI Condensation Point Analysis Energy Materials Water 0 0 0 1 0 Description: WUFI is a moisture modeling computer program developed by Oak Ridge National Laboratory (ORNL)/Fraunhofer IBP. It allows realistic calculation of the transient coupled one-dimensional heat and moisture transport in multi-layer building components exposed to natural weather. It is based on the newest findings regarding vapor diffusion and liquid transport in building materials and has been validated by detailed comparison with measurements obtained in the laboratory and on outdoor testing fields. WUFI analysis can be performed by EAI or a credible third party. Contact the Earth Advantage staff for more information on pricing. Health Land Benefit: High performance wall systems can sometimes create moisture issues inside the wall cavity of a home if the point of condensation is not carefully considered. WUFI Analysis allows for a complete analysis of the entire building assembly including thermal barriers, air barriers, vapor barriers, and area weighted U-values. Verification: EA Energy Modeler will perform the analysis and report the results to the builder. 2 Waste Management 2.1 Waste Management Page 8 of 70
2012 Earth Advantage Residential Measures Resource Guide 2.1.1 Develop and implement waste reduction plan Accountability Form: General Energy Health Materials Water 0 0 1 2 0 Description: Develop a waste reduction plan that identifies local options for diverting construction debris from the landfill. A copy of this document will be provided to Earth Advantage to gain credit for the measure. A new plan will need to be submitted with each contract renewal or a minimum of once per year. Land Benefit: Develop and follow a Waste Management Reduction Plan. This is a document that specifically lists the actions the builder and all trades will take to reduce waste. This document is to be provided to the builder by an EA representative. Verification: Builder will provide EA a copy of the Waste Reduction Plan. EA Rater will verify that the plan is being implemented by identifying examples of action items in the field. In addition, the builder or responsible party will complete the Accountability Form for this measure and forward it to the EA Rater. 2.1.2 Recycle 95% of clean wood and cardboard Accountability Form: General Energy Health Land Materials Prerequisite Description: Recycle 95% of all wood scrap and cardboard from the jobsite. Wood scraps can be ground up and uses as mulch or as fuel. Cardboard is generally used in the production of new paper products. Using construction waste for the production of new products or the generation of electricity is the preferred practice but jobsite warming fires are allowed during winter months. Water Benefit: Wood and cardboard are both highly recyclable materials, and recycling facilities are readily available in most urban and rural areas. The intent of this measure is to divert material from the landfill. Material diverted from landfills becomes new consumer products, building materials or fuel for boilers. Verification: The builder or responsible party will complete the Accountability Form stating that this measure was completed. Verifiers will look for material separation on site. 2.1.3 Recycle drywall Accountability Form: General Energy Materials Water 0 0 1 0 0 Description: The intent of this measure is to reward builders who go beyond the required recycling of wood and cardboard. Construction creates a large quantity of drywall scrap. Builder must recycle 90% of each material to gain the points for this measure. Points will not be given for disposing of or burning these items on site. Health Land Benefit: Recycling reduces the amount of material that is shipped to the landfill. Verification: Builder shall provide an Accountability Form. EA with documentation from the recycling facility or waste hauler identifying the material and quauntity diverted. Page 9 of 70
