The purpose of an energy audit (sometimes called an “energy assessment” or “energy study”) is to determine where, when, why and how energy is used in a facility, and to identify opportunities to improve efficiency.
PORPHYRA offers energy auditing services. It leads the audit process but works closely with building owners, staff and other key participants throughout to ensure accuracy of data collection and appropriateness of energy efficiency recommendation.
We can do 2 types of energy audit
Energy audits for the whole building by examining the building envelope, building systems, operations and maintenance procedures, and building schedules. Whole building audits provide the most accurate picture of energy savings opportunities at your facility.
Energy audits targeted to specific systems (i.e., lighting or heating, ventilation and air conditioning). Targeted audits may miss significant bigger picture energy savings opportunities, but may be a good route if you have specific energy efficiency retrofit projects in mind and limited funds to invest.
We follow the below energy audit process
| Project phase | Project milestone(s) | Project activities |
|---|---|---|
| Preliminary review of energy use | Facility benchmarked against similar buildings “Base energy load identified” | Collect and analyze utility data ” Calculate EUI and compare to similar facilities “Assess energy efficiency improvement potential” |
| Site assessment | Site data collected ” Immediate energy savings opportunities identified “Exit meeting held to discuss preliminary findings” | Interview building staff ” Visually inspect building and key systems “Collect data” |
| Energy and cost | EEMs prioritized according to | Evaluate utility and site data |
| Analysis | project and financial goals Savings estimates generated | Analyze energy and cost savings “Develop list of recommended measures” |
| Completion of audit report | Exit meeting held to walk through final report “Action plan developed for next steps” | Summarize findings “Present recommendations” |
