Question #

E8.2a — Light Sensors

Question

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

Applicability

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

Answer

Select all applicable:

    • Yes — More than 50% owner / landlord-managed interior lights have occupancy sensors
    • Yes — More than 50% tenant-managed interior lights have occupancy sensors
    • Yes — More than 50% tenant-managed interior lights have daylight/photocell sensors
    • Yes – More that 50% of exterior lights have daylight/photocells
    • No – less than 50% of building lights have sensors / controls

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.

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
