WWEC specializes in creating an energy project tailored to your needs. Whether you are just starting down the path to energy efficiency and need a simple, low-cost solution, or you are ready for a customized turn-key project, we are your energy solutions provider. We will bring value to your properties and generate real savings to improve efficiency.


While performing the utility bill analysis, we can also provide a Benchmark Analysis to determine whether you have sufficient savings to move forward with an Energy Audit, Energy Efficiency Program (EEP) or Energy Performance Contract (EPC). This is also an excellent no-cost or low-cost way for you to decide how much value an EEP or EPC could bring to your facilities before you invest time and money in the process of building a project.


Standard Energy Audit (ASHRAE – Level I)

The Level I Energy Audit is an excellent starting point to understanding the opportunities present for energy conservation measures (ECMs). It involves preparing a high level summary report detailing potential ECMs, describing the general configuration of the buildings, and defining the type and nature of energy systems. This level of audit verifies the energy project opportunity found in the Benchmark Analysis.

Preliminary Energy Audit (ASHRAE – Level II)

The Level II Energy Audit builds upon the findings of the Level I audit, adding detailed analysis of energy consumption to quantify base loads, seasonal variation, and effective energy costs. It includes an evaluation of lighting, air quality, temperature, ventilation, humidity, and other conditions that may affect energy performance and occupant comfort. We will provide a clear, concise report, detailing the generation costs and performance metrics. The expectation at this level is that the estimated savings results will be within ±15-20%. This is an excellent tool for evaluating whether or not to move forward into a Level III energy audit, which is more precise.

Investment-Grade Energy Audit (ASHRAE – Level III)

A detailed analysis conforming to ASHARE Level III standards involves comprehensive whole building energy modeling to determine savings potential to ±5%. This level of analysis includes precise cost estimating, detailed financial analyses, development of a self-funding project with a savings guarantee, cash flow analyses, amortization schedule, and analyses of what would happen if you waited (for a better interest rate, for example). As the project is finalized, we incorporate the simultaneous modeling of all possible ECMs in order to ensure we are considering the impact of one ECM upon another, i.e., savings interactivity. As our focus is bringing value to your property, we also provide a detailed life cycle cost analysis and a savings guarantee, if desired, when you enter into a turn-key EPC with us. The IGEA is required for HUD PHA projects and FEMP projects.

Detailed Energy Conservation Measure Development

Detailed energy engineering and design for your specific energy conservation objectives can be performed following any Level of Energy Audit. This is an excellent method to develop an energy project without going to the expense of investigating all possible measures. The Detailed ECM Development encompasses investigation of all other possible ECMs that would be within a specific payback range, often less than 25 years.


Reviewing your utility bills is an excellent way for us to prove our value to you. With no up-front costs, we will examine a year of your utility bills and tariff structures to find cost savings from overcharges, late fees, billings based on the wrong tariffs, etc. We can often achieve 10-15% or more of savings without performing any physical improvements! We are paid from your savings, so this is a win-win scenario for you.


Protect and sustain your investment by assessing its condition and useful equipment life. Having a systematic plan for replacement of aging equipment with energy and water efficient equipment will reduce your utility expenses and sustain the operation of your business.

Green Physical Needs Assessments (GPNA)

A GPNA combines elements of energy auditing and property appraisals into one report, providing information about life cycle costs of energy-efficient modernization needed for each property. HUD Public Housing Authorities will soon be required to have a GPNA performed every 5 years.

Capital Needs Assessments (CNA)

In order for a property owner to understand the future capital expenses of their property, organizations such as USDA Rural Development Multifamily Housing and HUD Rental Assistance Demonstration (RAD) Program require this CNA. As an ESCO, our focus is to make assessments based on maximal energy savings for the property owner.


WWEC can identify strategies and help you identify your ‘green’ direction. This is another effective first step to understanding potential fast-payback ECMs. Research of local, state, and federal rebates and incentives is another service we offer in order to get the most out of your energy goals. Consultation is most effective for potential clients who have strong facilities teams to develop the identified opportunities.

Energy Engineering and Design

Whether you are an architect/engineering firm in need of energy modeling for your current projects or you are a building owner that has the staff resources for an energy project but needs the engineering design expertise, WWEC can help. We review your project from an energy perspective, identifying and designing energy-related capital improvements that ensure long-term savings in operating costs.

Remote Energy Management and Ongoing Monitoring

The beauty of our industry is that it is evolving continually. Innovations in equipment and monitoring occur every day. That means it is to your advantage to stay engaged with us on your path forward in order to reduce costs by eliminating billing errors, late fees, double billing, metering malfunction, deposit recovery, rate analysis, and procuring electricity and fuel in deregulated regions. We can monitor your facility’s progress and utility bills remotely, and alert you to opportunities for further savings in a future phase of work.


Many of the products installed in an energy efficiency/conservation project deal with changing older equipment with more efficient technologies and identifies other creative approaches that might apply to specific structures. The projects need to reflect the operational capabilities of the owner’s team.


WWEC staff have managed over sixty EPC construction projects (pricing; RFP development;Davis-Bacon; project meetings, billings, etc) and have also managed conventional construction project.


For turn-key energy projects, or if you have a project you have already implemented and need to verify performance, we measure the savings annually using strict industry-approved guidelines to evaluate how the project is performing. This also includes annual monitoring to ensure the ECMs are still in place and functioning. Measurement and Verification (M&V) is how we ensure that our turn-key projects are meeting their savings guarantees.

3rd Party Service Provider for existing Energy Projects

Large ESCOs and energy companies often subcontract ongoing M&V for their energy projects in order to fulfill diversity goals by employing small businesses or minority-owned companies. As a Veteran-Owned Small Business (VOSB) with over 20 years of EPC experience, utilizing WWEC’s M&V services for large projects is a win-win.


WWEC excels at providing outstanding project management and implementation of EPCs and EEPs. From driving down implementation costs, to effective contract administration and site supervision, we have the team in place to provide you with outstanding project implementation.

Energy Performance Contract & Financing

An EPC is a turn-key energy solutions project that provides clients with project development, design, engineering, financing procurement assistance, subcontractor procurement assistance, implementation, measurement and verification, and a savings guarantee. The benefit of an EPC is that it allows you to leverage the savings from fast-payback ECMs to install longer-payback improvements, without increasing your operating costs at all! WWEC stands out at developing strong projects which maximize either capital improvements or the cash flow to the client, depending on your goals. Research of local, state and federal rebates and incentives is also a standard service we offer in order to get the most out of your energy project.

Energy Efficiency Program

An EEP is also a turn-key project for energy-efficient upgrades, but it is typically for smaller projects, with only fast-payback ECMs included. It does not include a savings guarantee and might be funded from reserves instead of from financing.

Savings Guarantee (included in EPC)

With any turn-key energy project we implement for you, we will offer a savings guarantee. We have implemented over 49 turn-key projects, with only one call on our savings guarantee due to a change in HUD regulations. If our project does not perform to our guarantee, then it is our responsibility to pay you dollar for dollar.

Staff and Occupant Training (included in EEP and EPC)

As a service, we also include pre- and post-training for occupants, administrative staff and maintenance staff on how to make the most of the ECMs installed. Our training encourages buy-in of all parties, which ensures your project brings value now and into the future.


In compliance with federal and state regulations, we can also prepare your next utility allowance study in low-income communities such as HUD Public Housing, Section 8 and USDA Rural Development Multifamily Housing


WWEC also addresses renewable technologies (wind, solar, hydro, etc). These projects can be paid for through power purchase agreements.


HVAC equipment requires periodic testing and adjustments to the system. There are several things that can influence the efficiency of an HVAC system. Periodic retro-commissioning can be a fairly inexpensive part of an energy efficiency project.
