Question #

E9.3 – Reducing Seasonal Peaks

Question

Have low-carbon opportunities been identified or implemented to reduce seasonal peak heating loads and heating/cooling electrical demand?

Applicability

Office, Healthcare, Enclosed Shopping Centre, Universal, Multi-Unit Residential Building, Light Industrial
Owner/landlord occupied building
Tenant occupied building – Owner/landlord has access to utility data

Answer & Scoring

  • Yes — opportunities identified = 1 point
  • Yes — opportunities implemented = 2 points
  • No = 0 points
  • Not Applicable – Tenant occupied building: Owner/Landlord does not have access to utility data = 0/0

Max of 2 points

Requirements

    1. List energy/carbon reduction measures proposed or implemented that specifically address peak demand and high thermal loads
    2. Indicate anticipated or measured reduction in electrical demand (kW

Proposed or implemented measures could include strategies, such as operational optimization and scheduling, system switchover, demand response programs, peak shedding programs, time-of-day usage or similar

Documentation

  • Energy/carbon reduction measures proposed or implemented
  • Anticipated or measured reduction in electrical demand

OR

  • Documentation demonstrating that the owner does not manage the lighting controls (e.g. lease agreement)

Suggested Lead

In-house, with third-party support

Value

  • Building off E9.1 – Peak Demand and E9.2 – Peak Demand Patterns, identify low carbon peak shaving opportunities
  • For additional points, buildings are encouraged to implement peak shaving strategies

Description

Consider low carbon peak shaving strategies to ensure that the effect of reducing demand is not to switch to a potentially less expensive but more carbon intensive alternative.

For example: reducing fan speeds during peak times is considered a low carbon peak shaving strategy; however, increasing gas boiler capacity to reduce air-source heat pump (ASHP) peak consumption is not.
