Commercial Building Energy Audits

The primary objective of this audit is to understand the overall performance of your facility relative to those of similar size, age, and use within similar climates. The process includes a review of utility consumption and an on-site survey of existing conditions including the review of your system configurations and modes of operation. Your Enviros energy team will use this data to establish the baseline for your facility and provide no or low-cost energy conservation measures to improve your building performance. Your team may also recommend additional investigations or larger capital improvements to meet energy goals if required.

A Level II Audit is intended to provide a clearer, more detailed picture of your facility’s performance, energy consumption, and operational challenges. Utility information is broken out by use to help identify inefficiencies. On-site inspections and diagnostic tests are conducted to pinpoint system issues. Your Enviros energy specialist will also interview site staff including facilities managers, operations, and maintenance personnel, and occupants to better understand your current performance and maintenance practices, and document functional deficiencies, problem areas, and enhancement objectives.

The Enviros team will then develop an energy model of your facility, perform engineering calculations, and identify potential energy conservation measures, or ECMs. The resulting report will include complete documentation of your facility’s equipment, existing conditions, and operational procedures, as well as upgrade recommendations with corresponding costs, estimated savings, and projected payback.

Sometimes referred to as an ‘Investment-Grade Audit’, this level of audit is typically used as the foundation for an energy performance contract where upgrade costs are paid for by future guaranteed cost savings. Our process starts with robust data collection and long-term trend analysis in both heating and cooling seasons using industry-leading wireless devices to collect data on equipment operations, temperatures, lighting levels, control settings, interior pressure relationships, and component failures. All data is incorporated into an energy model that simulates your building’s response to various upgrades, including major capital improvements, providing highly accurate energy and cost-saving projections. Your Enviros energy specialist will use these findings to provide prioritized recommendations for improvements along with energy savings and an anticipated payback period.
