Neil Bulger established A2 Efficiency in 2023 after recognizing a gap in the building design and research communities regarding the efficient communication and implementation of energy efficiency ideas. The current obstacles in decarbonizing buildings and integrating them into the larger electrical ecosystem demand comprehensive solutions that tackle multiple challenges simultaneously and involve various disciplines to be cost-effective. A2's goal is to act as a catalyst for change in this area.

A2 Efficiency got its name from a past integrated design project that involved weekly meetings with over 100 individuals from various disciplines in one room. During these meetings, any team proposing a change to the building, regardless of their sub-team or trade partner, was required to condense their idea into a single sheet of A2 paper. Although other teams also implemented this approach, A2 Efficiency embraces it as a fundamental concept. Our daily mission is to simplify complex solutions to ensure they are easily understood.
