Net-Zero Energy Homes (NZEH) are no longer a futuristic concept. Companies around the tri-state region have completed NZEH's. This session will provide an overview of the design and engineering parameters, construction techniques, challenges, and lessons learned from the construction of these homes. The presentation will also provide a case study of seven of the homes which have been occupied for as much as six years. The presenters will be sharing insights from their roles as a production builder and Energy Rater, including: a review of the design parameters, construction of high performance building enclosures, installation of ground-source heat pumps, incorporation of PV systems and navigating performance standards. Energy-use data monitoring will be presented as part of the session.
