Green Building Components
Components of Green Building
Site Selection
- Avoid environmentally sensivitve areas
- Choose an infill site whenever possible
Lot Design, Preparation and Development
- Conserve natural resources
- Minimize slope disturbance
- Align roads with natural topography
- Minimize soil disturbance and erosion
- Stockpile and cover good soil for later use
- Proper management of storm water
- Incorporate pre-existing natural vegetation into the landscape whenever possible
- Utilize permeable materials for parking areas, walkways and driveways
Resource Efficiency
- Use efficient floor plan designs
- Use detailed framing plans and detailed material takeoffs. Provide on-site cut lists for framing and sheathing material
- Use pre-manufactured roof framing package
- Provide a covered entry at exterior doors to prevent water intrusion and subsequent rotting of joists, sills and finishes
- Use recommended-sized roof overhangs for the climate
- Install gutter and downspout system to divert water 5’ away from foundation
- Divert surface water from all sides of building
- Employ flashing around all windows and doors
- Use scrap building materials wherever possible
- Use recycled-content building materials
- Use materials manufactured from renewable resources
- Use locally available, indigenous materials
Energy Efficiency
- Heating system designed and duct system installed in conditioned space using ANSI/ACCA Manual D
- Heating system sized appropriately, according to ANSI/ACCA Manual J edition
- Third party plan review
- Airtight building envelope
- 2x6” exterior walls
- Continuous thermal barrier/exterior insulation (Tyvek)
- Spray applied cellulose insulation
- Caulk bottom plate of exterior walls
- Energy Star Windows appropriate for local climate
- Windows flange sealed to sheeting
- Sheeting and dry wall form air barriers
- Caulk/foam all electrical, plumbing, heating penetrations between floors and to exterior
- All duct work sealed with mastic
- Stack Framing
- 2 ft. on-center wall studs and roof
- Install whole house tank-less water heater
- Install Energy Star-labeled appliances
Indoor Environmental Quality
- Install space heating equipment and water heating equipment in isolated mechanical room or closet with an outdoor source of combustion and ventilation air
- Install direct-vent, sealed combustion gas fireplace or no fireplace installed
- Install carpet, carpet pad and floor covering adhesives that hold “Green Label” from Carpet and Rug Institute’s indoor air quality testing program
- Use low or no VOC indoor paint
- Use low VOC sealants
- Vent kitchen range exhaust to the outside
Implementation
- Identify goals as a team
- Provide training to team members on green development practices that will be used onsite
- Create a checklist to be filled out onsite that contains only those targeted green development practices that will be implemented in each project
Homeowner Education/Operation and Maintenance
- Distribution of handout/flyer stressing importance of maintenance of energy efficient features
- Operation and maintenance instruction for equipment and appliances
- Explanation of the benefits of using compact fluorescent light bulbs in high usage areas
- A list of habits/actions to optimize water and energy use
- User-friendly maintenance checklist
- A list of local service providers
Benefits
- Lower operating costs
- Increased comfort
- Improved environmental quality
- Enhanced durability and less maintenance
