Net-Zero: The Next Generation in Green Building

What is a Net-Zero Home?

Building sustainably is about building an energy efficient, resource efficient, and durable home; about reducing your impact on the environment and reducing the ongoing energy costs associated with owning a home. Some of the highest performing homes are designed to be so energy efficient that they can use on-site renewable energy to produce just as much or even more energy than they consume. These homes are called "net-zero" because their energy bills are essentially zero.

Designing and building a home to consume no more energy than it produces can be challenging, as every last detail of electrical consumption, from appliances to air sealing, must be considered. Deltec has the building science and design expertise to make this goal a reality.    We now offer a net-zero building system, called our Zero Energy Home.

What is in the Deltec Zero Energy Home Building System?

We love our Deltec. It is a wonderful design and is VERY fuel efficient. It was green before green was cool. - Becky A., Greenville, SC

Due to the superior energy efficient design of the Deltec home, all the south facing glass and the active solar power equipment, the home is totally self sufficient.
 - John J., Telluride, CO

Our Deltec home has exceeded our expectations. It is comfortable inside and looks great outside. We are very happy with the energy efficiency and comfort of this design. - Marianne K., Harrisonburg, VA

Each time the gas company sends out a bill, they include a chart comparing our consumption with their average customer. Always, our consumption is just half of the average. - Ed B., Holcomb, NY

Our past electric bills ranged from $120 to 250. With our 4000 sq. ft. Deltec (around 3 times the size of our old house), our electric bill averages around $120, $130 per month. - Kim M., Magnolia, TX

We love our Deltec home. It is very energy efficient (we have not had a gas bill over $75 this year), spacious, easy to maintain, and incredibly "livable." - 
Daniel & Lynn W., Wildwood, PA

We have just gone through our first winter and I can't believe how tight this house is, and how it weathers the local winds which are occasionally pretty interesting. - Joseph R., Oakhurst, CA

Using regular windows, floor plan design & sub-tunnels we have such great natural lighting that we almost never need to turn on any lights in the house.
 - Beth H., Charleston, SC

Even on coldest days in Colorado, our house stays in the low 60s without using the furnace during the day. In the summer it never gets above 75 even if 15 degrees warmer outside. Love my house! - 
Suzanne M., Buena Vista, CO

Everyone else around us is crying about $500-$600 a month electrical bills and ours was $239.00 last month which is really low for Hawaii. - 
Keith B., Holualoa, HI

For our new home, we built to the basic Deltec standards…and our Deltec Home earned a HERS score of 34. Our home uses 66% less energy than code-built new homes. We’re very pleased with the energy efficiency. -Barbara P., Richford, VT- - Barbara P., Richford, VT
