E9.1 – Peak Demand

Question

Is the building’s peak electrical demand known?

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 = 1 point
  • No = 0 points
  • Not Applicable – Tenant occupied building: Owner/landlord does not have access to utility data = 0/0

Max of 1 point

Requirements

    1. Indicate the seasonal peak electrical demand values for the past year, highlighted on utility bills, monthly utility data summary or sub-metered data
    2. If electrical demand is not separately measured by the utility or the BAS, provide a monthly load profile based on electrical consumption for the past year with associated data

Documentation

  • Utility data analysis identifying the seasonal peak electrical demand values over the past year

OR

  • Documentation demonstrating that the owner does not have access to utility data (e.g. lease agreement)

Suggested Lead

Value

  • Peak electrical demand occurs when the highest amount of electricity is drawn from the electric grid. As more buildings move towards electrification, the demand on the electrical grid increases, increasing the risk of brownouts
  • Identify the building’s seasonal peak electrical demand over the most recent operational year
  • Understand when a building is most taxing on the grid to identify potential areas of reduction

Description

As more buildings “fuel switch” to electricity and as extreme temperatures become more frequent, additional burdens are placed on the electrical grid, particularly in peak seasons. This results in higher utility costs, less resilient infrastructure and the potential for a dirtier grid if gas-fired power plants are required to satisfy demand during times of peak usage.

Understanding peak demand patterns and schedules in buildings will allow building operators to identify opportunities to minimize the load and cost for electricity in heating and cooling seasons and other thermal heating fuel types.
