The greenlight for government buildings: strategies for a low-carbon building portfolio

Abstract

There is a global focus by governments on retrofitting buildings, as well as incorporating energy efficiency into new construction, as a means to address climate change. Initiatives to reduce energy use, source renewable electricity, and use low-carbon materials are aimed at leading by example, where governments attempt to showcase innovation through green building strategies. Greening government initiatives are promoted to reduce operating costs, improve energy system resilience, grow the “green” economy, support clean energy development, and encourage sustainable building practices. Here, we outline the benefits of greening government initiatives by examining Canada's Greening Government Strategy as a case study approach for transitioning to a low-carbon building portfolio. We focus our review on initiatives that outline how public institutions can transition buildings to reduce their carbon footprint by (1) pairing greening government mandates with adequate support structures for public agencies, (2) using an integrated energy management process for the planning and development of carbon-neutral portfolios, and (3) overcoming barriers to low-carbon project implementation with procurement standards, financial instruments, and staff training. These approaches are defined to offer leadership in the green building industry, strategically identify carbon reduction projects, and reduce barriers to a low-carbon building portfolio.
