Our energy engineering services will keep your building operating at peak performance!



Good energy management begins with an understanding of how a building uses energy. This “big picture” perspective gives a solid foundation for more detailed analyses on building systems and components. A building’s energy overall consumption profile is measured and documented during the benchmarking process. Our engineers can benchmark and compare all buildings in your property portfolio based on total energy and heating, cooling and baseload energy usage. This screening highlights the buildings in most need an energy assessment and efficiency upgrades.

Monitoring and Targeting


Our team can monitor the energy performance of your buildings, providing fast feedback about whether or not they are meeting predicted performance expectations. If not, we will figure out why, and recommend corrective action to achieve the energy saving threshold required for program incentives.

Measurement & Verification

measurement & verification

Measurement and verification (M&V) of energy and energy cost savings is playing an ever increasing role in helping building owners secure funding from financial institutions for energy efficiency projects. Studies show that less than 75% of predicted energy savings are achieved through traditional energy audits without M&V tracking. Our engineers verify that energy efficiency predictions were met, allowing owners to evaluate the actual return on investment from energy consumption reduction measures.

Let our staff of certified measurement and verification professionals (CMVP) help you on your next project.

Building Retuning

PSD offers a suite of Building Retuning services including tiered training, consulting, mentoring or turnkey building retuning service as part of our suite of Intelligent Energy Engineering services. When the DOE’s Consortium for Building Energy Innovation (CBEI) decided they needed to develop a curriculum for their new Building Retuning process, they turned to PSD to develop and deliver the curriculum.

TREAT Engineering Support

Our engineering team offers advanced support for this tool, including remote modeling, mentoring, and quality control.

Let our energy simulation certified staff help you on your next project.

Energy Management

We offer comprehensive Energy Management services, providing the combination of services you need either directly under our consultation, or as the lead contractor managing subcontractors.

Equipment Needs Survey

equipments needs survey

PSD engineering staff can survey all building equipment, such as elevator motors, air handlers, and pumps. We will assess the condition, offer advice on time to replacement. Additionally, we can and recommend the new equipment and an estimate of savings to offer the best payback for your investment.

OpenStudio Support Services

NREL’s OpenStudio platform for EnergyPlus is changing the way building professionals approach energy modeling - are you prepared for the shift? We offer a variety of OpenStudio support services to help you get there!

Energy Assessments (Audits)

energy assessmentDuring an energy audit, our engineers will assess how a building’s systems are performing, make recommendations on how the performance can be improved, and project the savings to investment ratio (SIR) so that you can make informed decisions. Our signature approach to multifamily and commercial auditing addresses the specific energy and operational needs of each unique building. Our goal is to help building owners increase the value of their property and reduce energy costs, while providing occupants with a comfortable, healthy environment.

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

  • Level I - includes a walk through audit, an analysis of consumption figures and documents, and a list of possible energy conservation measures.
  • Level II - an in-depth quantitative analysis to verify results found in the Level I audit, and also includes a full energy audit, measurements and a list of measures for funding and implementation.
  • Level III - this detailed engineering analysis gives owners a detailed evaluation of the costs and benefits of upgrades for informed capital improvement decisions.

April – November 2017

Building Science of Commercial Buildings @ Philadelphia - Delaware Valley Green Building Council
Apr 18 @ 8:00 am – 12:00 pm



The purpose of this course is to introduce building staff and management to the primary systems in commercial buildings that use energy.  This course will explain how the HVAC, lighting, and building envelope operate, interact, and use energy.  The attendees will learn examples of and good practices for energy efficiency opportunities, overview and tools for making sound economic decisions related to energy efficiency upgrades, and understand when to use nationally recognized energy efficiency tools and their expected level of effort and cost.

Intended Audience

  • Onsite operations and maintenance (O&M) staff looking to increase their knowledge of building science and how to identify energy savings opportunities
  • Building management seeking to become more familiar with how their buildings operate, which variables have the biggest influence on energy costs, and how and when to make energy efficiency upgrades that meet their economic criteria


  • High-level descriptions of and understandings of the following topics:
    • Building envelope
