Energy and Sustainability Due DiligenceTM

Whether multifamily, office, retail, industrial, or anything else in between, NOI Engineering assists real estate investors in evaluating energy efficiency measures and reducing utility costs.  Drawing on extensive experience in real estate development and energy consulting, our teamspecializes in translating the energy performance of buildings into financial terms.  This analysis gives our clients greater control of their utility expenses, helping to reduce financial risk in an unpredictable energy market.Nova offers 9 years of experience in the energy efficiency field, particularly in the multifamily market.  We provide non-database driven custom energy audit reports that allow for “outside the box” site specific solutions based on dialogue with clients.  Additionally, we have a database of 6,000 units of peer multifamily housing against which we benchmark your property and provide real metrics for making informed decisions.


Energy and Sustainability Due DiligenceTM conducted on a potential acquisition includes a thorough assessment of current energy use, utility structure, fuel and utility types. It also involves assessments of major energy-consuming systems and Federal, State and Utility based incentive, rebates grants and tax credits associated with any recommended energy improvements.  Energy due diligence on potential acquisitions answers the following questions:


  • How much energy is the property currently using?

  • How is it being used?

  • What is the financial impact of that energy use?

  • What is the most cost effective means to reduce utility costs, what are the potential funding sources?

  • How much value will this retrofit effort drive into the property?


Through energy benchmarking, energy auditing, energy modeling, retro-commissioning and energy incentive program analysis NOI Engineering provides comprehensive Energy and Sustainability Due DiligenceTM. We identify for owners, developers, asset managers and lenders what cash flow upside potential or expenses are impacted by a building’s energy performance. We then develop a comprehensive plan including cost estimates to increase cash flow through utility cost reduction.


Energy Audits


​The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines three levels of energy audits.


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: 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 by conducting an hourly simulated hourly model.Level III: Detailed Analysis (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: Detailed Analysis (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 monitoring, data collection and engineering analysis.
