19 Jun Pushing the Boundaries of Building Performance
GO Logic partner and principal architect Matt O’Malia addressed a group of New Hampshire AIA members last week, presenting a continuing education course on his firm’s evolving approach to high performance design and construction. Speaking in GO Logic’s recently completed Alnoba retreat center, Matt led the group on a deep dive into the design, detailing, and energy modeling of the very building in which the session took place. A 13,000 square foot, mixed-use structure that incorporates innovative structural and mechanical systems, Alnoba broke new ground for Passive House design in North America, which has focused predominantly on less demanding residential projects.

GO Logic’s basic building performance strategy prioritizes building envelope investments like triple-glazed windows, superinsulation, and air-sealing to reduce the size, cost, and operating expense of mechanical systems. The formula is simple in concept, but it takes on considerable complexity when applied to a building of this size and type. Matt shared the energy models, construction details, and test procedures that yielded the building’s near-zero energy performance, as well as some crucial lessons learned in taking the design through execution and delivering a building that performs as planned.
Matt also provided a glimpse of GO Logic’s current direction. Aiming to transcend the laudable but static goal of sustainability, the firm has targeted a “regenerative” standard of building performance, which demands that buildings and infrastructure produce more energy than they consume. Regenerative performance allows buildings not only to achieve carbon-neutrality in operation, but also to offset within their lifespan the carbon released in their production.
GO Logic’s R&D company, GO Lab, is working to bring that goal closer. Its current front-burner project is developing domestic manufacturing capacity for wood fiber-based insulation boards and batts that will cost-effectively supplant the energy-dense fossil fuel-based products that currently dominate the market. The result will be reduced operational energy use, less environmental impact in production and disposal, stronger local forest economies—and low-embodied-energy buildings that start life with less energy debt and a shorter path to life-cycle energy neutrality.
