E7.2 – Control Strategies

Question

What control strategies are in place?

Applicability

All asset classes
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:

    • Night or unoccupied setback = 1 point
    • Optimal start-up = 1 point
    • Occupancy and equipment scheduling = 1 point
    • Standby mode (occupied vs. unoccupied) = 1 point
    • Heating water temperature setpoints/reset = 1 point
    • Chilled water temperature setpoints/reset = 1 point
    • Supply air temperature setpoints/reset = 1 point
    • Outdoor air temperature setpoints/reset = 1 point
    • Demand controlled ventilation = 1 point
    • Programmable thermostats in tenant or residential suites = 1 point
    • Economizer control = 1 point
    • Fan/pump speed control through Variable Frequency Drives (VFDs) = 1 point
  • No = 0 points
  • Not Applicable – Tenant occupied building: No systems managed by the owner/landlord = 0/0

Max of 4 points

Requirements

  1. Identify appropriate control strategies for the building
  2. Demonstrate implementation

Documentation

  • Screenshots of BAS
  • Narrative describing whether control strategies are adjusted to align with changing operating hours. Provide justification if not feasible or appropriate.

OR

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

Suggested Lead

In-house, with third-party support

Value

  • Implement operational control strategies to optimize system operations
  • Use controls strategies to tailor systems to reflect a building’s use, occupancy, and day-to-day needs
  • Implement control strategies to improve building operations, save on operational costs, and reduce energy use and carbon emissions

Description

Through automation, building systems can be monitored and adjusted to ensure that they are performing optimally and can facilitate the implementation of energy and carbon reduction measures.
