Burton conducts comprehensive energy and water audits on behalf of our clients. We work in concert with facility personnel and report our observations and recommendations for energy and water efficiency improvements. We document our findings in the form of a detailed report, capturing more efficient process and equipment ideas at the facility, as well as applicable rebates via the local utility. These recommendations are divided into categories (i.e. Lighting, HVAC, etc.) and may include low and no cost operational and capital improvements. Capital projects are segmented and prioritized based on return on investment.
In addition to laying the groundwork for substantial energy savings and incentives, Burton’s energy engineering team can also conduct audits that will allow a facility to meet its energy audit requirements that are in effect for several cities throughout the country. The ordinances for several large cities also require large and medium-sized buildings to complete an ASHRAE Level II energy audit, building tune-up /retro-commissioning, or similar service every few years. Burton understands the complexities of these utility mandated audits and can advise on audit due dates, exemptions, and extensions, if necessary. Burton engineers have the necessary years of required experience and possess a recognized license or accreditation to perform audits to meet the various energy assessment requirements for most cities, and we will complete all aspects of filing to fully meet each city’s specific ordinance requirements.
Following is a sample table of measures from an energy audit report:
Burton also provides project management services to identify qualified equipment manufacturers and installation contractors, develop implementation timelines, obtain utility rebates, and measure and verify post-installation savings.
Following are some of the common findings and best practices that are typically identified from energy audits:
- Scheduling: In many buildings that we audit, there is equipment that runs when not needed.
- Control Setpoints: Most buildings have opportunities to optimize setpoints, such as space temperature, static pressure, differential pressure, chilled water and condenser water temperatures, etc.
- Adjusting for Actual Conditions: Most building systems are specified to operate correctly at peak, or extreme, conditions. However, these are not the actual conditions most of the time. We often find opportunities to adjust for actual load conditions.
- Equipment Efficiency: There are usually opportunities to upgrade equipment in existing buildings to newer, more efficient technology. Examples are upgrading to LED lighting and new HVAC equipment and controls, including variable frequency drive applications.
- Maintenance Issues: Depending on the age of the building and the equipment, maintenance issues can be a common problem. Examples include faulty dampers, bad sensors, and small leaks. While relatively insignificant when considered individually, these small items can have a significant impact on energy performance when combined.
- Time-of-Use: It is important to understand a building’s rate structure. We routinely find opportunities to shift operations to a different time of day to save on energy costs.
