6 Must Haves for Energy Efficient Homes

Whether it’s a new build or a remodel, energy efficient homes are on the rise. More homeowners are turning toward energy efficient products, materials and appliances as they build. This is partially due to rising energy costs, but also because of a renewed focus on sustainability and environmentally-responsible building practices.

There are numerous ways to create a more energy efficient home, but not all of them are suited for every climate or house. These six must-haves for energy efficient spaces work well in nearly all situations, helping you get closer to a net-zero energy home.

1. High Performance Insulation

The vast majority of homes today are under-insulated for their climate and energy usage. There are many types of insulation, but not all of them are ideal for stopping energy transfer or air infiltration.

Using high performance insulation, like the extruded polystyrene insulation made by Kingspan, can help lower energy bills and make your home more comfortable at the same time. Adding insulation to walls and roofing can help keep what energy you’re using right where you want it (and not flowing out the door).

2. Insulated Ductwork

One of the biggest sources of energy loss when it comes to heating and cooling a home starts right at the delivery system. Leaky, uninsulated ductwork can result in as much as a 20% loss of the energy you use to heat and cool your home.

By using pre-insulated ducts, you can prevent this kind of energy loss, which means all of the energy you use will reach its destination. And your HVAC system won’t be as overworked, which can also result in fewer maintenance costs and reduce a loss of efficiency over time, as well.

3. Tight Building Envelope

Air infiltration and heat transfer have been identified as the biggest sources of energy loss in the home. As much as 40% of the energy you use to heat and cool your home could be lost due to a poorly constructed building envelope.

When there are gaps at the studs or joints in the building, insulation, or sheathing, energy can flow out of the home. At the same time, air can infiltrate your home from the outside as well, which means your heating and cooling systems need to work harder to maintain an even temperature.


By creating a tight building envelope, either by using continuous insulation or by identifying and sealing those cracks, you help prevent significant energy loss. That translates into savings on your energy bills each month, and helps to ensure a truly energy efficient home.

4. Moisture Management

One of the components of creating a tight building envelope is to ensure good moisture management throughout the exterior of the home.

Moisture Management plays two roles for the home. First, it helps prevent water from infiltrating the home due to rain, wind and ice. Moisture management will also help prevent condensation and moisture from building up inside the home.

When there is no air infiltration, the differences in temperature and humidity between the interior and exterior of the home may lead to condensation and moisture build up in the interior walls. Over time, this can lead to problems like wood rot and mold growth. So, when creating an energy efficient home with a tight building envelope, it is equally important to implement a moisture management system through the use of continuous foam sheathing or a vapor permeable weather resistant barrier.

5. Lighting

Lighting is also one of the biggest sources of energy usage in the home. Natural light should be used whenever possible, and a home design should incorporate plenty of options for daylighting.

For artificial lighting, using LED light fixtures can help you reduce your energy usage by up to $300 each year when replacing standard incandescent bulbs and fixtures.

6. Energy Saving Appliances

Never underestimate how much switching to energy saving appliances throughout the home can save you, too. Any appliance that gets regular use, from kitchen appliances to hot water heaters to HVAC systems, come in several grades of efficiency.

Choosing both the right size appliance and selecting a model rated for efficiency will produce a significant reduction in energy usage in the home each year.
