Many projects can be a Passive Solar design, orienting to the sun and incorporating passive cooling.
- Double the minimum amount of insulation required. Use only non-toxic or recycled content insulation.
- Use low/no-VOC and formaldehyde-free paint. Use solvent-free adhesives.
- Use low VOC, water-based wood finishes.
- Use certified wood or finger-jointed wood for all finish trim.
- Expose the structure to avoid the need for additional finishes.
- Avoid wall to wall carpet, or use carpet tiles with a company with a take back program.
- If you must use drywall, use recycled content drywall. Try other natural wall finishes.
- Use composite lumber for all exterior decks.
- Replace up to 35 percent of the Portland Cement in the concrete with fly ash.
- Avoid vinyl products. Alternatives include rubber, turned up carpet, linoleum, etc. As an alternative to vinyl flooring consider linoleum, made from wood flour, resins and linseed oil. It's available in a variety of colors and can be cut and pieced in to any pattern you can dream up.
- Specify a light color roof in warm regions; a non asphalt roof allows for future water catchment.
- Avoid standard particle board cabinets and use formaldehyde-free medium density fiberboard, plywood or wheat board for cabinet boxes.
- Consider bamboo, reclaimed or sustainably harvested wood, and wheatboard for cabinet doors and drawers, and sealed with a no- or low-volatile organic compound clear finish.
- On-demand hot water pumping system rather than a whole house re-circulating hot water loop, which has proven to be inefficient for delivering hot water quickly.
- Any new toilets should be dual flush type. For $20, EcoFlush makes a kit to retrofit existing toilets to dual flush.
- Recycle job site construction and demolition waste. Change your general demolition notes to salvage all removed doors and windows for possible salvage or reuse.
- Use treated wood that does not contain chromium, CCA or arsenic for decking and sill plates.
- Landscaping uses drip irrigation system to save water and indigenous xeriscaping plants that require little water.
- Incorporate permeable paving at all driveways and exterior surfaces.
- Reuse concrete form boards, or reusable slip forms.
- Insulate foundation before backfill.
- Substitute solid sawn lumber with engineered lumber.
- Use OSB for subfloor and sheathing
- If you are going to use stucco siding, use integrally colored stucco.
- Install a whole house water filter.
- Provide conduit for future solar addition.
- Provide dimmers on all light switches.
- South and west facing walls to have a high thermal mass material (concrete, or earthen).
- All appliances to be high level Energy Star models.
- Pre-plumb for solar water heating.
- On demand, tankless water heaters.
- Provide heat reclamation GFX exchangers at all high use showers.
