The new Phius REVIVE Pilot program for retrofit is being developed around a vision for upgrading existing buildings so that, ideally, they do not cause greenhouse gas emissions either directly or indirectly, and also so that they can function using locally-generated renewable energy; the retrofit process itself also does not cause GHG emissions, directly or indirectly, and deficiencies are fixed, i.e. risks to indoor air quality. The scope includes land use, decarbonization, cost/equity, resilience, health, quality assurance, and phase planning. Resilience will be a key determinant of the requirements around passive measures, with a goal of covering critical loads using on-site or local-microgrid renewable energy generation and storage.
