Publicly sourced · organic order is not soldView provider listCommercial energy auditing services examine how a building uses energy and turn that investigation into practical decisions. Depending on the goal, the work may include utility-data review, an on-site assessment, equipment and controls analysis, energy-conservation measures, estimated savings and costs, and a plan for next steps.
An audit prepared for Washington or Seattle requirements may need to follow a particular rule, standard, format, or professional-review process. The official program—not this directory—determines whether a report satisfies a legal requirement. Ask the energy audit consultant to identify the governing requirement in writing before work begins.
The directory records public service claims, not audit quality. Confirm the intended use, audit level, systems included, site work, calculations, professional oversight, and final deliverables before hiring.
“Energy audit” can describe very different levels of effort. Tell prospective providers whether the priority is compliance, a capital plan, operating improvements, incentive documentation, or a detailed investment decision, then compare the proposed methods and deliverables.
Often associated with an ASHRAE Level 1 approach, this work develops a broad picture of energy use and identifies promising opportunities for further study. Confirm the site visit, data review, opportunity list, and level of cost and savings analysis included.
Often associated with ASHRAE Level 2, a more detailed audit evaluates building systems and develops energy and financial analysis for recommended measures. Ask which calculations, cost sources, utility rates, operating assumptions, and interactions between measures will be documented.
A deeper study may focus on a major project or measures that require more rigorous modeling, field measurements, vendor information, or design development. Labels such as Level 3 or investment-grade do not replace a precise written scope.
An audit can inform a regulatory pathway without completing every compliance task or construction step. Confirm which requirement the report addresses, who submits it, whether incentives are evaluated, and whether the auditor also designs, sells, or installs recommended improvements.
Short answers grounded in public program and federal guidance. The written scope still controls each engagement.
The scope can range from a preliminary walk-through to detailed system analysis, calculations, cost and savings estimates, and an implementation plan. The useful comparison is the written scope and deliverables—not the audit label by itself.
Not by itself. Depending on the building and compliance pathway, owners may also need benchmarking, an energy-management plan, an operations and maintenance program, reporting, and implementation of required efficiency measures.
No. Seattle Building Tune-Ups are a specific city program focused on identifying and correcting building operations and maintenance issues. An energy audit can have a different purpose, depth, and deliverable, so owners should confirm which requirement the proposed work addresses.
An audit can identify and prioritize opportunities; commissioning can investigate and verify how equipment, controls, and operating sequences perform. A building with controls or HVAC problems may need both, but the responsibilities should be separated clearly in each proposal.
