How to Insulate a Garage Door to Stop Heat Loss and Cut Energy Costs

An attached garage usually sits outside the heated envelope of the house, so its temperature swings with the weather. In winter, an uninsulated steel door behaves like a giant radiator, drawing heat out of the rooms next to it and pushing energy bills higher. Insulation slows that heat transfer through the door panels, and the

Solar Power for Lumber Yards and Construction Facilities: Design, Cost, and Payback

A lumber yard in Milwaukee installed a 50.7-kilowatt rooftop solar array in January and beat its production expectations in the first full month of operation.

Energy-Efficient Building Products: Heating, Windows, and Roofing

Heating, cooling, and water heating consume most of the energy used in a typical American home, and the products chosen at design time determine most of that bill. Energy-efficient building products have moved from a premium option to a baseline expectation: better windows, tighter ducts, and high-efficiency mechanical systems now pay back through lower utility

Energy-Efficient Timber Home Construction: Geothermal Systems, SIPs, and Ratings

A 7,000-square-foot timber home near Ann Arbor, Michigan, runs a full year of heating, cooling, and hot water for about $750. The house earned the national Energy Star five-plus rating, became the first home certified as green built in Washtenaw County, and placed in the top seven of nearly 400 entries for a National Association

Energy-Efficient Timber Frame Homes: Passive Solar, Thermal Mass, and Smart Zoning

Designing a home for one person is hard enough. Designing one for two adults, three children, and six pets is a different ballgame, and the house that wins that game earns every square foot. The 2,700-square-foot, three-bedroom, two-and-a-half-bath timber home near Mancos, Colorado that inspired this article fits its family because every system was chosen

15 Energy-Saving Strategies to Plan Into Your New Home

New homes hold a big advantage over existing homes when it comes to energy efficiency: none of the old materials or hidden problems get in the way when you build from scratch. The decisions that matter, from the window schedule to the water heater, all happen before the foundation is poured. If you are still

Halogen, CFL, and LED: Energy-Efficient Light Bulb Options

Traditional incandescent bulbs are gone from mainstream shelves, and the phase-out started with federal legislation on January 1, 2012. The 100-watt bulb went first, with one additional major wattage disappearing each year through 2014. Shoppers who grew up choosing between 40, 60, and 100 watts now face halogen, compact fluorescent, and LED options that differ
