Abstract: The Government of Canada is committed to reducing greenhouse gas (GHG) emissions by 90% below 2005 levels by 2050. Government entities are undertaking strategic evaluations of their portfolios to determine the most cost-effective pathway to achieve low-carbon operations. We have developed an energy planning analytics platform (Rosetta) to perform portfolio-wide energy/GHG evaluations. The platform uses prototype energy models to represent each building, and calibrates each model based on utility bills and building operation/condition surveys. After calibration, it estimates the energy/GHG savings and performs a life-cycle cost analysis for each measure. Rosetta was used for a Carbon Neutral Study involving a portfolio of 120+ buildings across Canada. The portfolio consists of mostly aging inspections stations and lab buildings. Rosetta quantifies the potential for GHG reduction strategies across the portfolio to develop a clear and tangible roadmap to a carbon neutral portfolio by 2050.
