Several factors impact the energy use within a building. The audit process can help building managers and occupants understand opportunities to reduce overall energy use through changes in behavior, equipment upgrades and operational changes. This section will help guide you through what to look for during your audit!

Before Going Out into the Field

• Collect building attributes:
  • Construction / renovation year
  • Commodities used
  • Commodities metered
  • Building classification (e.g., office, lab, residential)
  • Operating schedule
• Pull drawings
  • Mechanical systems
  • Lighting systems
  • Room types and floorplans
• Tools to bring
  • Note taking items
  • Floorplans
  • Camera/phone 
  • Safety gear (e.g., safety glasses, hearing protection, closed-toed shoes, lab coat)

In the Field

Building walkthroughs can reveal operational information that can impact energy usage. Look for things that seem out of the ordinary, such as water leaks, loud mechanical equipment, spaces that feel extra hot or cold, or propped open doors. Some of these items may be considered normal, but others may clue you into maintenance issues or operational concerns that should be addressed!

Take note of observations about the building occupants. How many people are in the building? Are certain spaces more populated than others? What time of day are you visiting the building, and is this a peak time, or off hours?  

Next, pay attention to personal equipment such as computers, televisions, printers, and small appliances. Do they appear to use settings such as sleep or standby functions, or are things constantly on and lit up?

Back in the Office

Compare your notes to building drawings and documentation. Do you see any discrepancies that may explain energy trends? Alternatively, do you have questions for the building manager or occupants about what you observed?
