Energy Audits

Our role during the energy audit is to identify low cost and no cost energy efficiency improvements and develop a list of feasible capital energy improvements for your building. Accomplishing this improves operations, comfort and preservation of capital. WorkingBuildings has experienced engineers and Certified Energy Managers on staff with experience conducting ASHRAE audits I – III and other various energy management services including building commissioning, energy modeling and LEED consulting.

Our proven optimization methods and energy audits deliver facilities that have a reduced carbon footprint resulting in financial savings. The potential for energy savings is different for every building. Our process can:

We provide a custom program aimed at the goals you have set for your facility and its operation. We base our energy audit program largely on ASHRAE’s Procedures for Commercial Building Energy Audits.

Preliminary Energy Audit
The preliminary energy audit calculates the building energy utilization index based on building gross square footage, one to three years of energy usage and characterization of building use. This preliminary information allows us to compare energy consumption for similar buildings, similar to comparing miles per gallon rating on automobiles.

Level 1 Energy Audit
The level 1 energy audit identifies the potential for improvement and conceptual approaches for closing the gap from a low performing building to a building that performs normally. We perform a walk-through survey of the facility to determine issues that affect efficiency. The types of energy consuming systems are noted and the various uses of the building are recorded. Low-cost and no-cost changes and potential capital improvements that can improve energy performance are also identified.

If the building has energy improvement potential, your options may be to perform retro-commissioning or a level 2 energy audit; both could be coupled with LEED-EBOM or ENERGY STAR services.

Level 2 Energy Audit
A level 2 audit focuses on identifying capital improvements. A level 2 audit will examine each mechanical and electrical system’s design, condition, maintenance practices and measure operational performance. Once this is established, a list of practical modifications will be analyzed by estimating cost and operational performance. Interactions for combinations of system modifications will also be assessed.

Capital Plan
Significant modifications to fundamental energy systems such as lighting or HVAC requires experience and planning. WorkingBuildings can assist as building commissioning authorities to help establish the owner’s project requirements and commission the installation of major systems. Once the capital plan is implemented, our commissioning authorities will commission the equipment from component level to integrated system to optimize the performance and long-term viability of your investment. A capital plan may be based upon a Level 3 Energy Audit. Implementation of capital improvements may lead to ENERGY STAR, LEED certification, or both.

Level 3 Energy Audit
A level 3 energy audit will follow the level 2 and will include more details in order to more accurately assess the costs and benefits of energy improvements for identified systems. A detailed analysis of possible capital-intensive modifications including equipment lists, modeled savings, contractor estimates and budget contingencies. The information produced in the Level 3 energy audit should be schematic in nature and accurate enough for most capital budgeting processes. The engineered level of detail will not be final design, but must provide enough information for professional cost estimating. The expected accuracy of the budget will be included along with any recommended contingencies.
