Question #

E8.3 – Lighting Zones

Question

Are lighting controls installed in the building, where appropriate?

Applicability

Office, Healthcare, and Universal
Owner/landlord occupied building
Tenant occupied building – some or all systems managed by the owner/landlord

Answer & Scoring

  • Yes = Points as indicated below

Select all that apply:

  • Yes — lighting is on timers, scheduled or individually controlled = 1 point
  • Yes — spaces are zone controlled = 2 points
  • No = 0 points
  • Not Applicable – Tenant occupied building: No systems managed by the owner/landlord = 0/0

Max of 3 points

Requirements

    1. Mark up a floor plan or take photos to indicate extent of lighting controls installed throughout the building

Documentation

  • Sample of floor plans, photos or BAS screenshots of zoned controls installation

OR

  • Documentation demonstrating that no systems are under the building owner/landlord’s control (e.g. lease agreement)

Suggested Lead

In-house

Value

  • Most buildings have multiple uses or tenants that have different operational periods. When all lighting is on the same schedule, it does not reflect a building’s lighting needs and results in operational inefficiencies
  • Implementing lighting zones at a building will reduce energy consumption associated with superfluous lighting
  • Assign multiple lighting zones in a building’s BAS to account for each building’s use. Schedule zones independently to match each zone’s operational schedule

Description

Reduction of lighting energy consumption can reduce electricity consumption and costs, lower impact on the electrical grid, assist with ensuring that there is sufficient capacity for building electrification or EV charging, and reduce carbon emissions associated with electricity, particularly where the electrical grid has a high emission factor.

Optimization can be achieved through efficient fixtures and enhanced controls while also maintaining occupant safety.
