Energy Efficiency Checklist
Invest in Your Building Staff: Training & Certification Opportunities
Building Operator Certification (BOC)
BOC training equips building operators with the knowledge to improve energy performance and save on operational costs. Learn more at BOC Central.Green Professional Skills (GPRO)
The GPRO Operations & Maintenance course offers actionable strategies for improving building efficiency. Ideal for facility managers and engineers, find upcoming courses at GPRO Training.
This material is based upon work supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) under the Building Technologies Office Award Number DE-EE0010930. Specifically, this resource has been adapted and localized for California from a resource originally developed for The Building Energy Hub with permission from the Illinois Green Alliance.
By improving the energy efficiency of their building, building owners and managers can find long-term financial savings while also reducing emissions, enhancing tenant comfort, and helping relax strain on the electrical grid. Use this checklist to identify opportunities for your building.
Low-Hanging Fruit: No-Cost and Low-Cost Improvements
1. Check Your Building Scheduling
Building Controls
Ensure your building controls or automation system is properly scheduled to avoid lighting and conditioning spaces when unoccupied. Check out this brief video from Slipstream for examples.Programmable Thermostats
If you don’t have an automation system, install programmable or smart thermostats and communicate regular set points with building occupants.
2. Regular Preventative Maintenance
Routine maintenance keeps equipment running efficiently.
For example, replace air filters, clean evaporator and condenser coils, and tune up systems per manufacturer recommendations. Following these practices can reduce energy costs by 5-20% annually.
3. Address Plug Loads
Plug and Process Loads (PPL)
Nearly a third of electricity used in U.S. commercial buildings powers devices like computers and printers. Turn off unused devices, enable power management settings, and reduce unnecessary plug loads. Learn more here.
4. Encourage Energy-Efficient Behavior
Occupant behavior significantly affects energy use. Encourage employees to turn off lights and equipment and communicate energy goals within your building. Check out the Building Energy Hub’s Plug Loads and Tenant Energy Use Reduction Tech Primer to explore additional strategies.
5. Weatherize and Reduce Air Infiltration
Seal Air Gaps
Use weatherstripping and caulking to seal doors and windows, and close roof and freight entrances when not in use. Review the Building Energy Hub’s Tech Primers on High Performance Windows and Wall Insulation for more ideas.
6. Upgrade Lighting
LED Lighting
Switch to LEDs for substantial energy savings. Additional savings can be realized by installing occupancy sensors and daylight-responsive lighting controls.
7. Retro-Commissioning (RCx)
What is RCx?
RCx is a building "tune-up" that optimizes existing systems for efficiency. This is ideal for large buildings and can identify low- or no-cost improvements.
8. Get an Energy Audit
An energy audit or energy assessment identifies energy-saving opportunities, potential costs, payback times, and available incentives and rebates.
There are three types of energy audits, established as industry standards by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers.) They are listed below from simplest to most detailed.
Walkthrough Audit (ASHRAE Level I Audit). Provides an initial, cursory walkthrough of the building and its systems and equipment, which is accompanied by a review of a building’s utility bills. It is intended to only provide a high-level overview of no- or low-cost energy savings measures and should be considered a starting point to understanding potential savings opportunities.
Detailed Audit (ASHRAE Level II Audit). Provides an analysis to identify measures with greatest energy savings and financial cost-benefit based on a fuel-use analysis alongside interviewing on-site staff.
Investment Grade Audit (ASHRAE Level III Audit). Highly detailed engineering analysis of capital-intensive measures alongside financial analysis for potential investments.
Invest in Your Building: Medium-Cost Measures and Long-Term Investments
Upgrade Building Controls
Building Automation Systems (BAS)
Install a BAS or upgrade your controls to improve overall building management to a BAS if your building doesn’t have one.
Invest in Efficient HVAC Systems
HVAC Upgrades
Heating, ventilation, and air conditioning systems account for the largest portion of building energy use. Consider upgrading to more efficient systems during renovations or end-of-life replacements. Check out different HVAC upgrade options at the Building Energy Hub’s Technology Primer webpage.
Variable Frequency Drives (VFDs)
Install VFDs on motors (pumps, fans, etc.) to optimize their energy use.
Improve Your Building Envelope
Insulation and Roofing
Improve insulation during renovations for better energy performance. Additionally, installing reflective "cool" roofs can reduce heat gain during summer months. Review the Hub Tech Primer on Wall Insulation.
Windows
Replace single-pane windows or apply Low-E film to enhance the performance of existing windows. Review the Hub Tech Primer on High Performance Windows.
