Energy and Carbon Conservation Measures

Question #

E5.2 — Conservation Achieved

Question

Is there evidence that energy efficiency improved or carbon emissions reduced due to measures implemented in the past ten years?

Applicability

Applicable to all buildings (systems or equipment in the owner or landlord’s control)

Answer

Select all that apply:

    • Yes – energy efficiency improved
    • Yes – carbon emissions reduced
    • No – energy improvements or carbon reductions were not achieved

Description

The real impact of specific energy improvement or carbon reduction measures is often clouded by the impact of ancillary operational activities and equipment performance, as well as pre-and post retrofit measurement and verification (M&V) methods. Consider to what extent the weather and occupancy contribute to the before and after consumption or emission results, and normalise the data accordingly. Operations and maintenance (O&M) activities changed substantially during Covid, and O&M activities post-Covid may also differ from pre-Covid activities. There may be other factors that impact performance before and after implementation, whether it is the consultants providing support, the measurement devices used, the timing of measurement intervals etc. Establish measuring parameters before the implementation of the ECMs or CRMs to develop more reliable results.

Requirements

    1. Identify the energy and or carbon reduction measures implemented in the past ten years that are known to have caused energy efficiency or carbon reductions
    2. Reference measured data and prepare high-level M&V analysis to demonstrate efficiencies or reductions achieved
    3. Describe performance before the measure(s) were implemented and how performance changed after the measure(s) were implemented
    4. Describe how operational changes due to Covid etc. were considered and excluded from the high-level M&V analysis

Documentation

    • High-level calculations and brief narrative describing reductions achieved

Savings achieved can be specific to a particular ECM or CRM, or may apply to the whole building, whatever data is available.
