A provider of energy engineering services with a primary focus on assessment of commercial, institutional, and industrial facilities

About us

Warren Energy Engineering, LLC is a fully independent provider of energy engineering services with a primary focus on assessment of commercial, institutional, and industrial facilities. As a small company, the principal, Kevin Warren. P.E., is intimately involved in all projects. You are guaranteed that an experienced, professional energy engineer is working on your project.

Mr. Warren has worked throughout the energy efficiency delivery structure. He has performed analyses such as energy audits, developed commissioning plans and measurement and verification plans, and has conducted inspections for customers under incentive programs. He has performed quality assurance activities and conducted impact evaluations of programs. He has also performed energy engineering analyses independent of publicly funded programs for a variety of clients, including energy services companies (ESCOs) and end-users.

Mr. Warren has a Bachelor’s Degree in Mechanical Engineering from the University of Delaware and an M.S. Degree in Mechanical Engineering from the University of Wisconsin – Madison Solar Energy Laboratory. Mr. Warren is a registered Professional Engineer (P.E.) in four states, is a Certified Energy Manager (CEM), and a LEED Accredited Professional. He is a member of the Efficiency Valuation Organization's (EVO) International Performance Measurement and Verification Protocol (IPMVP) Committee. He is active in regulatory affairs related to energy efficiency in Pennsylvania through his membership in the Keystone Energy Efficiency Alliance (KEEA).

Energy Audits

Warren Energy Engineering provides a full range of audit services from walk-through audits (ASHRAE Level I), preliminary scoping studies (ASHRAE Level II), to investment grade audits (ASHRAE Level III). Our audits meet the requirements of LEED-EB:O&M EA Prerequisite 1 and LEED-EB:O&M EA Credit 2.1 using Option B.

An investment-grade energy audit conducted by Warren Energy Engineering will include an in-depth investigation of the facility, analysis of opportunities, and assessment of potential projects. We rely on state-of-the-art tools and calculation methods and stay informed of the latest developments in energy efficiency. Whenever possible, we make use of short term metering to record actual facility operating conditions and use such data to identify deviations from intended design and control. We most commonly perform our savings estimates with proven custom spreadsheet-based calculations. Such calculations are fully documented and transparent. For customers who require greater detail, whole-building simulations, most commonly performed with eQUEST, are also offered.

Program Impact Evaluations

Warren Energy Engineering is an engineering analysis resource for evaluating and verifying the impacts of energy efficiency programs. We perform on-site assessments of measures to confirm proper installations. We then review program savings projections in order to assess program impacts and facilitate future improvements to the program. We are accustomed to seeing applications that are unique and have performed such evaluations in several industries. We take pride in applying sound engineering methods to evaluate the accuracy of projected energy savings.

Green Building Support / New Construction Design Assistance

We have extensive experience conducting new construction design assistance in commercial buildings. We provide this service directly to end-users and their design teams. We also assist other firms through computer modeling support. DOE-2 is the most popular, and time-proven, hourly model for estimating energy use in buildings. Using the eQUEST™ implementation of the tool allows us to promptly and accurately build models for use in schematic design. The software incorporates a database of default information (such as schedules, construction materials, design specifications, etc.) to facilitate timely modeling solution. Our modeling services are ideal during the schematic design stages of buildings when many project details may not be available. eQUEST™ maintains the full DOE-2 rigor, further allowing us to incorporate complex details when modeling existing buildings or completed designs. This has been the primary tool used in our larger new construction analysis projects.

We perform these services in support of LEED-NC applications through our partnership with Tillou Engineering.

Measurement and Verification

Warren Energy Engineering can provide complete measurement and verification services in support of performance contracts or other projects where proven energy savings are required. We have performed short and long-term monitoring at numerous facilities and are well versed in the leading M&V protocols including the International Performance Measurement and Verification Protocol (IPMVP), the Federal Energy Management Program (FEMP) application of the protocol, and California’s Standard Performance Contract (SPC) protocols. Mr. Warren is a member of the Efficiency Valuation Organization’s IPMVP Committee.

We have extensive experience performing all of the potentially complex IPMVP options. We are expert users of the Metrix™ software for performing whole building billing analyses, Option C, and also expert users of eQUEST for the calibrated simulations required under Option D.


Provided with accurate and complete energy usage history for your facilities, Warren Energy Engineering compares your energy usage to other similar facilities within or outside your organization. This is a great first step prioritizing energy audits within a large population of facilities. One benchmarking option we provide, is to use the EPA EnergyStar portfolio manager as a standalone benchmarking tool or as the first step to EnergyStar Certification.

ENERGY STAR Certification

Most major building types (including office buildings, K-12 Schools, retailers) as well as several industrial facilities (including auto assembly plants and cement plants) are eligible for ENERGY STAR Certification. Such certifications require both benchmarking of energy bills and a certification statement by a registered P.E. Warren Energy Engineering, LLC has staff licensed in Pennsylvania, Delaware, New York, and California and has partnerships with P.E.s in many other states.

Demand Response Audits

Demand Response Programs are an increasingly important resource for reducing energy costs are large facilities. In our area, the PJM, NYISO, and ISO New England all offer attractive programs that reward customers for reducing demand in response to grid needs. We combine an assessment of your facility with interviews with management to determine the technically feasible and institutionally acceptable measures. We have conducted studies for several large universities and manufacturing facilities.

Retrocommissioning (RCx)

Retrocommissioning calls on many of the same skills as an energy audit. We find and correct the areas in which a building is using energy suboptimally. True retrocommissioning relies heavily on metering and monitoring of building systems. We are a Quality Assurance contractor with NYSERDA for their Retrocommissioning program, overseeing and approving project reports, M&V plans, and M&V reports. Measurement and verification (M&V) for retrocommissioning can be a complicated matter, and Mr. Warren is proud to serve on the Technical Advisory Group for the California Commissioning Collaborative’s Verification of Savings in Retrocommissioning Project.

Utility Program Support

Much of our work is preformed in support of utility or public goods funded energy efficiency programs. We adapt our analyses to the requirements of the program. Our knowledge of program evaluation has improved our program support work by allowing us to most fully understand the ways in which programs must document and defend their results.

Warren Energy West Grove, PA
Warren Energy Engineering, LLC is located in West Grove, PA. The office is within the National Bank of West Grove building, originally constructed in 1883. Recently, a bank and the Borough post office shared the first floor, while the West Grove Library and Tyson Photographic Studio/Temperance Lodge occupied the second and third floors. The building has played host to much of West Grove's history:
The first edition of the West Grove Independent was printed on the second floor in 1884 by the West Grove Printing Company, the hometown newspaper for approximately 80 years.
The first West Grove Borough Council meeting was held in the second floor library.
Previously, the Borough used the upper floors as offices for the police station. The lower levels served as a jail for a small period of time.
