Building America Case Study: BrightBuilt Home, Modular Zero Energy, Portland, Maine

R. Aldrich, K. Butterfield

Research output: NRELFact Sheet


Kaplan Thompson Architects (KTA) has specialized in sustainable, energy-efficient buildings, and they have designed several custom, zero-energy homes in New England. These zero-energy projects have generally been high-end, custom homes with budgets that could accommodate advanced energy systems. In an attempt to make zero energy homes more affordable and accessible to a larger demographic, KTA explored modular construction as way to provide high-quality homes at lower costs. In mid-2013, KTA formalized this concept when they launched BrightBuilt Home (BBH). The BBH mission is to offer 'a line of architect-designed, high-performance homes that are priced to offer substantial savings off the lifetime cost of a typical home and can be delivered in less time.' For the past two years, CARB has worked with BBH and Keiser Homes (the primary modular manufacturer for BBH) to discuss challenges related to wall systems, HVAC, and quality control. In Spring of 2014, CARB and BBH began looking in detail on a home to be built in Lincolnville, Maine, by Black Bros. Builders. This report details the solution package specified for this modular plan and the challenges that arose during the project.
