Boston-based WegoWise, a building-performance analytics startup, says it was able to identify $137 million in lifetime energy savings in 2011 for buildings that are part of Mass Save's Low-Income Multifamily Program, which invests in energy-efficiency upgrades in low-income housing facilities across Massachusetts.
The multiyear program is being implemented by the Low-Income Energy Affordability Network (LEAN) and the Mass Save sponsors—Massachusetts utility companies—that have used the WegoWise platform to track and benchmark energy and water use at more than 45,000 low-income multifamily units in the state. Barun Singh, WegoWise founder and chief technology officer, says the platform enabled LEAN to look across entire portfolios of low-income housing to identify the "outlier" buildings that were underperforming. The building owners could then perform audits and target retrofits for the least efficient buildings.
