Six key elements work together to make this house appealing: insulation for an R-50 SIP wall assembly and an R-60 foundation; triple-glazed windows; diligent air-sealing; minimized risk of thermal bridging; attention to indoor-air quality; and a super-insulated slab foundation that picks up heat during the day and releases it slowly at night.
Waste heat recovery is a possible way to achieve net zero at home. Jeff Wilson investigates a holistic approach.
How LEDs (Light-Emitting Diodes) work, why they are more efficient than traditional lighting, where to install them.
Here are new twists on energy efficiency: eco-friendly demolition, and recycling construction materials as-you-build so there's no waste...
You’ve swapped your incandescent lightbulbs for compact fluorescents, turned down your water heater, and set up your programmable thermostat. These are all good moves toward saving energy in your home, but what else can you do?
In recent years, water issues have become a very hot topic. Water shortages throughout the western United States, as well as severe droughts in the southern, have made water usage a major concern. Many green building experts agree that with a growing global population we can no longer rely only on water conservation. Even for residents in gloomy states, solar panels can greatly reduce power costs, let alone carbon footprints. In fact, because of solar power success in Germany, the state of Washington (a state that receives overcast days 65% of the year) decided to copy Germany’s solar financial incentive programs. Let’s take a closer look at some factors to consider before making a purchase decision.
