Achieving net-zero is not an easy task, it takes careful attention to detail and intelligent design. All of this home’s energy is produced on-site by an 8,100 Watt solar array. In order to get to net-zero, every energy-consuming feature has to be carefully considered, from the light bulbs to the heating and cooling systems to the windows and insulation. You will learn about energy-saving techniques around every corner in this home.

These are some of the features that this home utilizes to get down to zero energy consumption:

Capturing the Power of the Sun

Every angle and orientation of the home and within the home must be thoughtfully considered in order to allow for the optimal sun exposure.

This home is oriented from east to west, with primary living spaces on the south and the garage on the west and north side. The extra bedrooms and closets must be on the north and the large windows on the south side. There are thoughtful calculations for the depth of the eave to help promote shade in the summer and sun in the winter. And of course, the southern facing roof must be able to accommodate PV panels to reach the goal of net-zero.

Building an Incredibly Insulated, Air Tight, Durable Home Shell

In order to build a net-zero home, the house must be insulated extremely well and have air tight seals around the entire house so cold air doesn’t escape in the summer and warm air in the winter.

The walls are constructed to reduce thermal bridging and insulation was increased to R-48. The subfloor must be constructed to accept extra insulation—this home has R-48 insulation in the floor. Raised trusses accept R-60 loose fill fiberglass. The windows are triple pane, U-0.18 to U-0.20 and reach an air tightness of 2.0 ACH or less.

Reduce Energy Consumption in the Home  

Of course, in order to obtain a net-zero home, you must take control of your energy use within the home. There are many simple tasks you can do in any home so be sure to check out our Quick Tips/DIY tips or our Simple Saturday activities to reduce your energy use in your own home

In this SolAire home they ensured that the mini-split ductless heat pumps are sized appropriately with the Energy Performance Score model and Manual J modeling. Also, the hot water heater and the energy recovery ventilator are located in conditioned space inside the home. Furthermore, this homes uses 100% LED lighting and Energy Star Appliances – saving the environment and saving you money.

Model for PV System Size: “Icing on the Cake”

This specific home needs 7975 kW of solar electric panels to reach Net Zero Energy. In Bend, Oregon this translates to 9465 kW hours of estimated total annual production.

If you’ve ever considered going solar before, this is a great opportunity to learn about the tax credits and incentives that can help make your solar dream home a reality; whether it’s on your current home or a new home!
