THE NEW AMERICAN HOME (TNAH), which features stunning contemporary design, earned an Emerald-level NGBS Green certi cation by incorporating the latest green and sustainable building materials, products, energy-ef cient techniques and construction methods in order to reduce its impact on the environment and provide the highest levels of comfort and quality of life for the occupants. The 2017 TNAH offers a collection of ideas about construction technology, design concepts, optimal housing performance, and healthy living features that others in the home building industry can take away and incorporate, in whole or in part, in any home, built anywhere, at any price point. Through the home’s systems engineering, Phil Kean Design Group demonstrates how to optimize energy performance without signi cantly impacting the cost of construction. 

KEY ENERGY FEATURES

In designing TNAH, Phil Kean Design Group worked with building partners to select cost-effective strategies for improving home performance and minimizing the material used. Advanced systems engineering and innovative practices make this 8,245 sf home both extremally energy efficient and cost effective. Remarkably, the home achieved 43% energy improvement over the ICC IECC 2009, before taking the additional photovoltaic array into account. This home also achieved remarkable air tightness — 4.7 air changes per hour (ach) —with rigid exterior wall insulation combined with blown-in berglass wall and roof system insulation for thermal performance.

Because of the conscientious design and thought- ful construction planning, TNAH achieved net-zero meaning the total amount of energy used by the building is roughly equal to the amount of renew- able energy created on site. Solar energy is used to power a portion of the electrical systems, space conditioning, and hot water systems and the 17.1 KW photovoltaic (PV) system will provide much of the annual energy needs for the home. TNAH also features both natural gas and an electric car charging station in the garage.
