MassSave Program Overview

51

Through the Mass Save Program, utilities collaborate to help reducebuilding-related energy consumption

As part of the Massachusetts Green Communities Act, a system benefit

surcharge is applied to all gas and electric utility bills

Funds are collected and turned around to customers in the form oftechnical assistance and incentives

Retrofit, New Construction, and Technical Assistance programs

Kendall Square is expected to grow significantlybetween now and 2050

Growth is expected to be dominated by buildings with

high EUI

Current goal is to reduce GHG emissions citywide by

at least 80% by 2050

‘Business as usual’ would result in more than

doubling of GHG emissions in Kendall Square

Net Zero Action Plan: The Impetus p e t u s



Net Zero Action Plan: The Impetus

• Significant construction activity in the city and concern that any

new development makes reducing GHGs harder, unless Net Zero

• Zoning petition filed by residents requiring all new buildings to be

Net Zero or annual offsets required (Connolly Petition)

• City Council instead charged Getting to Net Zero Taskforce with

developing plan within 12 months

• Net Zero Action Plan adopted by Council on June 22, 2015
