Please list core areas of company expertise:Step 1: Identifying opportunities - G/BA is a leader among companies providing benchmarking, energy audits, and retro-commissioning. These services start the process by establishing a prioritized list of facilities to assess and determine goals, and then identify low-cost/no-cost measures through RCx and capital projects through the energy audit.

Step 2: Implementation - G/BA engineers are ASHRAE award winning designers for energy savings projects that replace chillers, boilers, air-handling units, DHW, and other energy-consuming systems in buildings.

Step 3: Commissioning, Measurement and Verification - G/BA is able to develop calibrated whole-building energy models for complex projects that require verification, and is also able to provide commissioning of new central plant upgrades to make sure the complex new systems operate as intended.
Please list relevant experience providing energy services in the Chicago metro area:G/BA has provided benchmarking services to hundreds of facilities through ENERGY STAR Portfolio Manager, and has maintained a free hospital energy and cost benchmarking survey for 20 years.

Our participation in utility-funded programs has allowed clients to receive free or co-funded studies to leverage their own funding for maximum benefit.

G/BA has also been recognized as a top provider in the Smart Ideas for your Business Retro-Commissioning program every year.

ENERGY STAR Portfolio Manager and our Hospital Energy Survey demonstrate the savings our clients have made over time through the process of identifying potential energy reductions, implementing low-cost measures, developing capital priorities, installing more efficient systems, and verifying the results.

A new service in conjunction with City of Chicago Benchmarking Ordinance is to provide automated ENERGY STAR Portfolio Manager uploads for facilities to maintain their accounts throughout the three-year cycle of submissions to the city.

G/BA also provides services for assessment of MEP equipment in terms of service life, reliability, and code compliance. This is valuable experience that informs our energy efficiency recommendations so that the owner's benefit is maximized in the long term and not focused solely on short-term energy savings.
Please describe your experience that qualifies you to conduct benchmarking and data verification services, including specific training on use of Portfolio Manager, ASHRAE Level I, II or III audits (or similar):G/BA has performed hundreds of energy studies for clients in the area, and more studies for healthcare facilities in the Chicago area than all others combined.

Staff members have served on the ASHRAE committee to rewrite the ""Procedures for Commercial Building Energy Audits"" and currently serve on committee SPC 211, developing an energy audit standard. Selection for the committee is based on years of experience in the field providing audit services for complex and energy-intense facilities.

The most common energy audit type for larger facilities is equivalent to a Level II. This level of study allows clients to document their energy use and provides actionable recommendations. G/BA has provided over twenty Level III energy audits. These are recommended for facilities that are implementing many measures that interact, and requiring a calibrated energy model that will be used to justify the project economically and verify savings. Level I audits can be a useful tool as well, and G/BA recommends that clients not be fixated on ASHRAE levels but work with us to identify a beneficial scope that will lead to successful implementation, and which may include engineering tasks across more than one ASHRAE level.

G/BA is also a qualified provider in several utility programs that may offset the cost of an assessment for certain clients.

In the past 10 years, G/BA has created or maintained several hundred ENERGY STAR Portfolio Manager (ESPM) accounts. More than 10 staff members are fluent in using ESPM.
Provide a brief summary of your experience providing building improvements to enhance energy performance:G/BA has designed MEP improvement projects for clients that have claimed over $2.1 million of ComEd incentives for energy efficiency, in addition to clients receiving incentive funding from natural gas companies and publicly-owned clients receiving DCEO funds. Our work is recognized by our client base, which turns to us as their engineer for complex retrofits of energy-intensive facilities. Most of our clients are repeat business, returning to G/BA for additional projects after having favorable experience with prior implementation.
