Saving Energy: It Starts At Home

Like the family featured in the article published by National Geographic (below), a common problem that many older homes face is air leakage ( Up to 40% of energy loss). Releasing your conditioned air and hiking up your energy costs,  air leaks can costs you hundreds of extra dollars per year. When Icynene spray foam insulation is properly installed, it creates an envelope around your home by expanding 100x it application size, filling gaps and sealing your home. This can help save up to 50% on heating a cooling for your home!

Saving Energy: It Starts At Home

We got some help in Week Two from a professional “house doctor,” Ed Minch, of Energy Services Group in Wilmington, Delaware. We asked Minch to do an energy audit of our house to see if we’d missed any easy fixes. The first thing he did was walk around the outside of the house, looking at how the “envelope” was put together. Had the architect and builder created any opportunities for air to seep in or out, such as overhanging floors? Next he went inside and used an infrared scanner to look at our interior walls. A hot or cold spot might mean that we had a duct problem or that insulation in a wall wasn’t doing its job. Finally his assistants set up a powerful fan in our front door to lower air pressure inside the house and force air through whatever leaks there might be in the shell of the house. Our house, his instruments showed, was 50 percent leakier than it should be.

One reason, Minch discovered, was that our builder had left a narrow, rectangular hole in our foundation beneath the laundry room—for what reason we could only guess. Leaves from our yard had blown through the hole into the crawl space. “There’s your big hit,” he said. “That’s your open window.” I hadn’t looked inside the crawl space in years, so there could have been a family of monkeys under there for all I knew. Sealing up that hole was now a priority, since heating represents up to half of a house’s energy costs, and cooling can account for a tenth.

Air rushing in through the foundation was only part of the problem, however. Much of the rest was air seeping out of a closet on our second floor, where a small furnace unit was located. The closet had never been completely drywalled, so air filtered through insulation in the roof to the great outdoors. Minch recommended we finish the drywalling when the time comes to replace the furnace.
