Energy Auditing, All Levels

Knowledge is power. The audit is where it starts.

The most powerful tool in energy conservation is a rigorous audit. SRG brings the tools, the data discipline, and the field experience to show you exactly where you stand — the gold standard when accuracy and detail matter.

The best audits come from the best tools and techniques

At SRG we take enormous pride in the quality of our data collection and analysis. When accuracy and detail matter, we are the gold standard.

The best tools

Proven, third-party-vetted analysis

An extensive suite of calculation and analysis tools, vetted by decades of third-party review.

Data is king

Robust data collection

The most rigorous field data techniques available, so every number holds up under scrutiny.

Compliance is coming

Get ahead of the mandate

The regulatory environment is moving toward mandatory energy auditing. The time to establish your baseline is now.

Full ASHRAE audits, or a targeted study built to your need

SRG teams dig into the smallest details of site energy use and find every hidden way a facility wastes energy — anywhere in the world, at any scale.

ASHRAE Level I–III

Full-scope energy audits

Field observation, infrared imaging, equipment inventory, BAS review, and utility analysis, documented to support investment decisions.

Targeted studies

Bespoke energy reports

When a full ASHRAE audit is not precisely what you need, we scope a focused study to your energy and sustainability requirements.

What a high-quality ASHRAE Level II audit looks like

A representative large-facility engagement: a mixed-use commercial and entertainment building of roughly 670,000 square feet. Three days of intensive field observation, spot readings, staff interviews, and twelve months of utility billing history.

Across seven major operational categories, from HVAC controls to refrigeration

Each measure was documented with observed conditions, proposed conditions, savings methodology, estimated cost, and simple payback — everything the client needed to prioritize and act.

Patterns that individual building analyses miss

Across a recent nine-building municipal portfolio of more than 1.1 million square feet, a consistent finding emerged: outdoor-air conditioning was the dominant recoverable heating load. At five of eight sites, outdoor-air reduction and demand-controlled ventilation was the single highest-saving measure by gas consumption — a pattern rooted in pandemic-era ventilation increases that were never dialed back. Portfolio-level rigor is what exposes not just the average, but the outliers that justify early, targeted investment.

Knowing where you stand, month to month

For campuses managing many buildings under one energy program, ongoing reporting matters as much as the initial audit. Across a technology campus of more than 20 metered buildings, monthly electrical use ranged from 1.5–1.8 million kWh in the largest buildings down to 4,000–15,000 kWh in support facilities. Building-level reporting lets you compare against prior-year baselines and track peak demand — so unexplained growth gets caught before it becomes a budget problem.
