Using Calibrated Energy Models to Help Understand, Manage and Improve Existing Building Energy Performance

Luka Matutinovic

Abstract: Energy modelling has a long and well-demonstrated track record of adding value to the design process for new buildings, by helping inform and evaluate design decisions that impact energy use. Its use in existing buildings is much less widespread however, in part because decisions about managing and improving energy performance can be informed by other wellestablished methods such as energy audits, retro-commissioning and sub-metering. However, just as energy modelling enables a comprehensive, collaborative and contextualized way to design low energy buildings, so too can it provide an effective method for achieving lowenergy existing buildings. This paper presents several case studies where calibrated energy models were used during a comprehensive energy investigation to identify and analyze opportunities to improve energy performance, and discusses lessons learned, including the benefits of calibrated energy models, and ways in which the conventional energy modelling process used in new buildings must be adapted for the unique challenges of existing buildings.
