Energy Audit, Energy Monitoring and Feasibility Studies for Buildings
Pinpoint your savings, prioritize the right projects and take action.
What a building energy audit includes
An energy audit shows how energy is used in a building, where the main consumption points are and which actions can improve its performance and reduce its greenhouse gas (GHG) emissions. Combined with continuous energy monitoring, it lays the groundwork for the feasibility study, which validates the technical and economic relevance of a project before moving to implementation.
- Building energy analysis and breakdown of consumption by end use (e.g., heating, cooling)
- Continuous energy monitoring (weekly, monthly) and trend analysis
- Energy monitoring of critical equipment (e.g., chillers)
- Utility bill monitoring
- Benchmarking against references (energy use intensity, $/sq. ft.)
- Identification of no-cost, low-cost and capital energy-saving measures
- Technical and economic evaluation of energy efficiency and decarbonization measures, including incentives and payback period
From energy audit to feasibility study
Energy data analysis
- Compilation of energy consumption, demand and billing data
- Data normalization for relevant comparisons
- Tracking of consumption indicators (energy use intensity, $/sq. ft., etc.)
- Identification of consumption anomalies and no-cost or low-cost energy-saving measures
- Identification of rate opportunities
- Energy cost allocation and rebilling
ASHRAE-type energy audit
- Consumption history for recent years
- Breakdown of building energy consumption by end use
- Benchmarking against reference buildings
- Identification of low-cost and capital energy-saving measures
Continuous energy monitoring
- Digital energy monitoring platform fed by utility data
- Definition of critical monitoring indicators (e.g., electricity consumption of a chiller producing chilled water)
- Energy performance tracking against established criteria
- Corrective actions proposed as soon as an anomaly is detected
- Measurement and verification (M&V) reports on savings
Feasibility study
- Identification of energy efficiency measures and decarbonization options
- Estimate of budget, energy and financial savings, incentives and payback period
- Recommendations on which projects to implement or not
- Prioritization of interventions based on their impact and required asset maintenance
- Option to carry out the work to make the project as profitable as possible

FAQ
Why conduct a building energy audit?
A building energy audit shows where, when and how energy is consumed in a building, in order to identify waste, priority corrective measures and the most profitable investments. It can be complemented by continuous energy monitoring and a feasibility study.
What is an ASHRAE-type energy audit?
ASHRAE is North America’s reference organization for building engineering; its Standard 211 sets out practices for commercial building energy audits. An ASHRAE-type audit performed by E’nergys includes consumption history for recent years, a breakdown by end use, benchmarking against references and the identification of low-cost and capital energy-saving measures.
How much does an energy audit cost?
The cost of an energy audit depends mainly on the size and complexity of the building, the depth of analysis required and the data available. In Canada, utility programs such as Hydro-Québec’s Efficient Solutions program and Enbridge Gas energy assessment incentives can help fund building energy analyses, reducing the net cost of the audit.
What is the difference between an energy audit and a feasibility study?
An energy audit assesses a building’s current performance and identifies improvement opportunities. A feasibility study goes further: it evaluates the technical and financial relevance of a specific project, including budget, expected savings, incentives and payback period. E’nergys performs both, so you can move from diagnosis to a quantified action plan.
What does an energy feasibility study include?
A feasibility study identifies possible energy efficiency measures and decarbonization options, then estimates the budget, energy and financial savings, incentives and payback period for each. It concludes on which projects to implement or not and prioritizes them based on their impact and required asset maintenance. For a long-term view, it can be part of a decarbonization plan.
Are there incentives for an energy audit?
Yes. In Quebec, Hydro-Québec’s Efficient Solutions program provides financial support for building energy analyses. In Ontario, Enbridge Gas offers incentives covering up to 50% of eligible energy assessment costs for qualifying customers. E’nergys identifies the applicable programs and prepares the applications. Check your eligibility for incentives.
Can energy costs be reduced without major investment?
Yes. In many buildings, energy bills drop through operational adjustments, schedule optimization, better equipment management or anomaly correction, without major work. That is the goal of mechanical system recommissioning (RCx).
What does continuous energy monitoring include?
Continuous energy monitoring tracks a building’s consumption over time to quickly detect drift. E’nergys uses a digital platform that collects utility data, tracks critical indicators, proposes corrective actions as soon as an anomaly is detected and produces measurement and verification reports. This data also supports the energy disclosure required by some regulations.
What deliverables do I receive?
Depending on the mandate, E’nergys provides a consumption profile, performance indicators, a breakdown of energy uses, a list of recommended measures, cost and savings estimates, and a prioritization of projects.
How are energy savings verified?
Savings are verified through measurement and verification (M&V), which compares actual consumption against a reference baseline, using recognized methods such as the International Performance Measurement and Verification Protocol (IPMVP).
Can E’nergys implement the work after the audit?
Yes. E’nergys designs, implements, finances and guarantees energy efficiency projects. The audit’s recommendations can lead to turnkey work or an integrated project, carried out without tying up your capital and with guaranteed results.
