PASSIVE DESIGN FOR ENERGY EFFICIENCY AND SUSTAINABILITY


Use Site Potential
  • design for solar gain
  • designing to use less, allow light into the home (to blur inside and outside)
  • use orientation and the landscape
  • design big, rather than just building big
  • design for longevity, flexibility and practicality of living.

Eco Materials
  • use materials that are renewable and recyclable
  • use materials that are natural
  • use materials that have low embodied energy
  • use materials that are long-lasting (if you need to replace it in 10 years, it is not sustainable)

Energy Efficiency
  • efficient building envelopes (high-performance insulation and windows/doors)
  • high performance heating and cooling systems
  • on-demand water heaters
  • maximizing benefits with solar orientation to maximize natural light and breezes, while minimizing any unwanted heat gain (designing for different seasons and various climates)
  • use energy efficient appliances
  • use solar gain in conjunction with high thermal mass (slow release of energy back into the home)
  • CFL and LED lighting
  • energy metering systems
  • alternative energy systems such as solar, wind generation and geo-thermal

Water Conservation
  • low-flow showerheads and faucets
  • dual-flush toilets
  • permeable walkways and driveways
  • rain-water harvesting

Environmentally Friendly Products
  • non-off gassing paints and other materials
  • air-filtration systems (combine with heat recovery)
  • use foam insulation (to reduce probability of mold in walls)
  • hard floor surfaces with carpet tiles or rugs placed on them)
