Zero Net Energy: Cost Effective Solutions

JANUARY 20, 2016 || 10:00AM – 11:00 AM

Presenters:

Jon Webb || KEPHART, Denver, CO

Steve Easley || Steve Easley & Associates, Danville, CA

Ann Edminster || Design AVEnues LLC, Pacifica, CA

Gene Myers || Thrive Home Builders, Denver, CO

Session Description

Many residential codes and ratings today are based on the goal of

minimizing energy use. Some codes are going beyond simply

minimizing though, so it’s important to be prepared. In this advanced

session, our highly-informed and passionate panel will describe the

cost-effective approaches they’ve developed to help single family

builders achieve zero net energy (NZE) homes as painlessly as

possible, and how you can, too, regardless of where in the country

you are building.

Learning Outcomes

Analyze key elements of successful ZNE design and construction that can be incorporated today to differentiate your homes from the competition.

Discuss ZNE standards currently being adopted, providing advance insight into codes likely to spread throughout the U.S. in years to come.

Review illustrated examples of recommendations developed for production builders to cost-effectively adapt their existing designs to meet ZNE requirements.

Explore why organizational capacity-building, and not adoption of risky new technologies, is the key to an effective transition to achieving ZNE.

ZEN Building Science Center—The Power of Zero

If I told you that if you gave me $100 I would give you $300 back, would you take it?

Every month?

For 30 years?

That is a lot of money…maybe your child’s college education.
