BOMA Canada’s response to Winter 2018 updates to ENERGY STAR Portfolio Manager
Summary: Following the upcoming change to the calculation of ENERGY STAR Scores, BOMA BEST certified buildings will simply use the new methodology. We have provided a brief grandfathering period for this transition. We expect that the impact on BOMA BEST scores will be modest. Details below.
Natural Resources Canada has announced changes to ENERGY STAR Portfolio Manager that will take effect in Winter 2018. The precise date for these changes is not yet public though our understanding is that the changes will occur in early February.
The updates are as follows:
- Scoring model for ENERGY STAR Score-eligible buildings will be based on 2014 Survey of Commercial and Institutional Energy Use (SCIEU)
- Calculations for parking, pools and data centers will be updated
- Source energy factors for electricity, natural gas, fuel oil, propane, steam, hot water and chilled water will be updated
What does this mean for your BOMA BEST certification?
Launched in 2013, the ENERGY STAR score is percentile-based – it scores building energy efficiency relative to a fixed data set. The current data set was based on the 2009 Survey of Commercial and Institutional Energy Use. A new survey was conducted recently to collect data for 2014, and this data will be used to update the ENERGY STAR scoring model for eligible buildings (in BOMA BEST: Office and some Universal buildings). The new model will provide a more up-to-date ENERGY STAR comparison for Canadian buildings’ energy use. This change will impact each building differently, but we expect, in general, that the impact on BOMA BEST scores will be modest.
BOMA Canada has given significant consideration to this change and has consulted with several stakeholders. Guiding us throughout has been our foundational view that BOMA BEST must encourage the continuous improvement of building performance. As such, BOMA BEST’s underlying assessment methodology will remain unchanged following the Winter 2018 ENERGY STAR changes. Buildings will simply continue to obtain an ENERGY STAR Score based on the output from ENERGY STAR Portfolio Manager at the time of BOMA BEST certification.
Exemption: If a building’s performance period is measured entirely before the Winter 2018 updates, BOMA Canada will accept the score from the earlier ENERGY STAR version for a period of three months from the ENERGY STAR update. To qualify, applicants must provide evidence of the score via a screenshot of the ENERGY STAR or BOMA BEST portals taken prior to the update.
