Energy efficiency is very important to Rita and me, so the first thing we did when we purchased our current home was to pay for an energy audit to identify opportunities for making the home more air-tight. One result of that test was to blow additional cellulose insulation into walls and ceilings and to caulk around windows. We considered installing an energy recovery ventilator (ERV) to bring fresh air into the home using a heat exchanger that warms outside air in the winter and cools outside air in the summer. Instead we installed a fan in our powder room that runs 24/7 at a very low volume, but higher when occupied.
I love bringing sunlight into a home, with sun tunnels. Rita and I had Mark Lundquist of Design Skylights install a Velux sun tunnel in our garage and another one in our laundry room. (He installed four more at Golden Real Estate.)
Speaking of sunlight, we replaced every light bulb in our home with LEDs which are “daylight” color.
Installing solar photovoltaic panels is a no-brainer now that the cost has dropped so much. Your roof doesn’t have to face due south. Southeast and southwest are good enough. Since everyone will be driving an electric car eventually, install as much solar PV as Xcel Energy allows to cover that future load.
Don’t you hate climbing a curb to enter your driveway? Developers install mountable curbs the entire length of residential streets, because they can’t know where each driveway will be. One of the first things we did at our home was to remove the mountable curb in front of our driveway. It cost about $2,000 for our 3-car-wide driveway, but we love it every time we enter from the street!
When your gas forced air furnace needs replacing, consider replacing it with a heat-pump or hybrid furnace. And when your gas water heater needs replacing, I recommend buying a heat-pump water heater. We bought a 50-gallon Rheem unit for $1,200, but it came with a $400 rebate. Once you’ve replaced both, you will have eliminated the most common sources of carbon monoxide poisoning in your home.
Other improvements I’d recommend: Replacing any bathroom carpeting with ceramic or porcelain tile; replacing regular double-pane windows with Low-E windows on south-facing windows; replacing fluorescent fixtures (as we did in our garage) with flush-mount LED panels sold at Lowes for about $100. Love ’em!
