Question #

E8.2a – Light Sensors

Question

Are occupancy or daylight sensors installed in owner or landlord-controlled spaces, where appropriate?

Applicability

All asset classes
Owner/landlord occupied building
Tenant occupied building

Answer & Scoring

  • Yes = Points as indicated below

Select all that apply:

    • Yes — More than 50% owner / landlord-managed interior lights have occupancy sensors = 2 points
    • Yes – More than 50% of owner/landlord managed exterior lights have daylight/photocells = 2 points
    • Yes — More than 50% tenant-managed interior lights have occupancy sensors = 2 points
    • Yes — More than 50% tenant-managed exterior lights have daylight/photocell sensors = 2 points

  • No – less than 50% of building lights have sensors / controls = 0 points

Max of 4 points

Requirements

    1. Mark up a floor plan or take photos to indicate extent of occupancy and/or daylight sensors installed

Documentation

  • Sample of floor plans or photos of light sensor or controls installation

Suggested Lead

In-house

Value

  • Traditionally, lighting at a building is scheduled for its operational hours. This method of lighting does not account for occupant use or natural light which often results in unnecessary artificial lighting
  • Implement lighting controls, to turn lights on and off based on occupant needs and the weather conditions to save on energy associated with lighting

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.
