Energy Auditing
An energy audit is a systematic analysis of a building’s energy-use systems to identify cost-effective improvements that will save energy.
Drawing upon our expertise in building systems design, installation and operation, Synergy Engineering offer holistic approach to energy auditing by examining the building envelope, building energy-use systems, operations, maintenance procedures and operating schedules. Whole building audits provide the most accurate picture of energy savings opportunities.
Local Law 87 requires energy audits and retro-commissioning of “base building systems” which includes, but is not limited to, the building envelope, HVAC systems, elevators and escalators, domestic hot water supply, and electrical and lighting systems.
Synergy’ Professional Engineers (PE) and Certified Energy Managers (CEM) are experts in performing investment grade Energy Audit and Retro-Commissioning.
We have assisted multiple property owners to go beyond mandatory compliance with LL87 and used this opportunity to review property operations, identify inefficiencies and devise low to no-cost measures with immediate payback.
When infrastructure upgrades are warranted and coincide with ownership goals, Synergy Engineering assists properties with specifying, implementing, inspecting and commissioning energy efficient upgrades, while attaining significant rebates from State and City Agencies.
Levels of Energy Audits
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines three levels of Energy Audits. Each audit level builds on the previous level. As audit complexity increases, so does thoroughness of the site assessment, the amount of data collected and the detail provided in the final audit report. This effort can translate into higher energy savings.
Level I: Site Assessment or Preliminary Audits identify no-cost and low-cost energy saving opportunities, and a general view of potential capital improvements. Activities include an assessment of energy bills and a brief site inspection of your building.
Level II: Energy Survey and Engineering Analysis Audits identify no-cost and low-cost opportunities, and also provide EEM recommendations in line with your financial plans and potential capital-intensive energy savings opportunities. Level II audits include an in-depth analysis of energy costs, energy usage and building characteristics and a more refined survey of how energy is used in your building.
Level III: Detailed Analysis of Capital-Intensive Modification Audits (sometimes referred to as an “investment grade” audit) provide solid recommendations and financial analysis for major capital investments. In addition to Level I and Level II activities, Level III audits include energy modeling, monitoring, data collection and engineering analysis.
