The CEG Approach

  • Energy Efficiency

    We have deep expertise with a wide range of technologies that can reduce energy consumption. This allows us to consider a diverse set of strategies for upgrading your building systems.

  • Renewable Energy

    We consider each of the available potential sources of renewable energy at each location and determine the best solution for your facility.

  • Water Conservation

    Inefficient water usage across the built environment, is driving up water costs and quickly becoming a significant problem.

  • Occupant Engagement

    Our comprehensive projects include occupant engagement programs because they are powerful tool for generating utility savings.

  • Sustainability

    Sustainability measures help to go beyond the bottom line and deliver results that improve the environmental attributes of facilities and organizations.

Energy Efficiency

A complete understanding of the fundamentals of construction, particularly the relationships of complex integrated systems, is critical to energy efficiency measures in both new construction and existing facility retrofits. With our extensive construction experience, we fully understand the world of energy efficiency as it applies to the built environment. We bring the knowledge necessary to implement projects that produce guaranteed results, without putting your facility at risk.

Addressing ECMs in isolation often leads to suboptimal solutions. The final product of a comprehensive energy project can be much greater than the sum of its parts. Interactive effects often compound when multiple measures are implemented, creating additional “free” savings beyond the savings that would be realized if each ECM were implemented in isolation. This is why the CEG approach is rooted in exploring a wide breadth of ECMs that address every significant aspect of a building’s operation to achieve the deepest cuts in utility consumption. Our approach to deep energy retrofits addresses a building’s envelope (façade) and utility-consuming systems, along with organizations that operate within the building, individuals that occupy the building, and (renewable) resources available to the building.

An integrated strategy that addresses each of these disciplines compounds overall building efficiency, increasing the cost-effectiveness of each individual measure. Our innovative design process consistently enables us to dig deeper (beyond “first-cut” ECMs) and deliver cutting-edge projects.

Load Reduction

Building load reductions are necessary to drive significant efficiency improvements. Primary systems that dictate a building’s load include the envelope, MEP systems, lighting systems, IT equipment, plug loads, and building controls. These systems can be upgraded, retrofitted, retro-commissioned, downsized, and/or removed in buildings where efficient design principles can be properly implemented. Typically the constraints imposed by a pre-existing building make efficient design challenging. However, due to our roots in construction and our experience developing innovative, high-efficiency retrofits, we have the capability to complete transformational renovations without disrupting operations.

Efficient Systems

Remaining loads may be handled with resource-efficient MEP systems, lighting systems, IT equipment, plug loads, and building controls that are deeply integrated into the building’s overall design to help maximize cumulative efficiencies of systems. CEG’s portfolio demonstrates our depth of experience with highly efficient building equipment. In some cases, it makes the most sense to utilize the existing building systems and simply retrocommission them for enhanced performance. Often, savings from low-cost ECMs such as retrocommissioning can assist in achieving even deeper utility reductions by helping to fund upgrades of other systems that we might not have otherwise had the budget to replace.

Energy Recovery

Often, it is possible to recapture and reuse energy that is being exhausted from the building to perform useful services, offsetting the amount of energy required to operate the building. Potential opportunities for energy recovery include: capturing heat from boiler flue gases to increase the efficiency of boilers, pre-conditioning incoming air with warm or cool air from ventilation exhaust, using heat from certain wastewater streams to preheat water, using waste heat from data centers to preheat water, and reclaiming mechanical energy from elevators. We have implemented energy reduction systems that range from refrigeration heat recovery to ventilation enthalpy wheels.

Renewable Energy

The CEG team has a strong record of successfully delivering renewable energy solutions for a wide array of applications. Our audits include a thorough analysis of available renewable resources and identify potential sources of energy that are not being captured or are being used inefficiently. We then determine locations at your facility where this renewable energy could be harvested – considering both building-integrated solutions and those that use previously underutilized land. The renewable energy survey for your location will also include an analysis of available incentives, potential savings from on-site renewable energy, and the approximate implementation cost at your given location.
We can help you tap into any type of renewable energy, including solar photovoltaic, solar hot water, solar space heating, solar cooling, biomass, landfill or digester gas, wind, micro- or mini-hydro, geothermal, and ground source heat pumps, among others.

We track and monitor federal, local and utility programs and leverage them to offset the cost of your projects. In particular, we can structure our projects to utilize federal tax incentives (investment tax credit or production tax credit, including the cash grants in lieu of tax credits), state tax incentives, state grants, federal grants, renewable energy certificates (RECs), carbon credits, utility rebates or other incentives, feed-in tariffs, subsidized loans, system benefit trust funds, accelerated depreciation, and more. If there is money available for your project, we’ll find it.

Water Conservation

Water conservation has become a major issue in our country and around the globe. Beyond the global impacts associated with our inability to consume water at a sustainable rate, inefficient water usage across the built environment, especially in the arid Southwest, is driving up water costs and increasing scarcity.
CEG analyzes water consumption in every site audit that we perform. Our water conservation audit process begins by examining each site’s historical water use, current patterns of usage, makes/models/locations of water fixtures, and functional status of each piece of equipment. We have expertise in domestic water, process water, cooling tower water, and irrigation water efficiency solutions, with experience across residential, commercial, and industrial settings.

CEG has implemented many creative water conservation measures in the past, low-flow and dual flush toilets, waterless urinals, faucet sensors, appliance replacements, irrigation system upgrades (physical and controls), green roofs, on-site wastewater treatment, HVAC water chemical treatment, ground water re-use, xeriscaping, and reverse osmosis purification system upgrades. Our team has the capability to expertly identify, design, and implement water ECMs that go beyond those the standard domestic, quickly delivering deep savings and ROI, increasing the overall savings both in the near and long term.

Occupant Engagement

CEG goes beyond basic stakeholder management in occupied buildings; in addition, a key part of our strategy is engaging building occupants. This can be as simple as teaching occupants how to override the automatic night set-back, or it can fundamentally transform how occupants interact with the built environment. Key aspects of our deep retrofit strategy are “Occupant Engagement Programs” and “Organizational Engagement Programs,” both of which work to streamline how occupants and organizations utilize their infrastructure. One potential manifestation of these programs is the “hoteling” system, which replaces assigned desks with unassigned, flexible work spaces that foster collaboration and efficiency. Hoteling can be complemented by a cultural shift in the office that encourages telecommuting, which has potential to significantly reduce the client’s utility consumption. Our experience has proven that working with tenants in occupied buildings enables us to achieve deeper cuts in utility consumption. For past projects, we held multiple “Awareness Days,” which informed occupants about the energy and water retrofits that were taking place at the campus. We also incentivized occupants to attend sessions where we distributed training materials and tools to help occupants to reduce their electricity bills.


From selecting the right building materials to evaluating the first cost and life cycle cost of a facility, CEG is committed to guiding our clients through every step of the decision-making process to ensure that they receive the most innovative, environmentally conscious, and financially feasible solutions for their projects. We take a practical approach to sustainability, analyzing the implications of the counsel we give to determine just how it will impact our clients, communities, and the environment in, both the short and long term. Over the past two decades, we have compiled a stable of best practices, which we use to assist our clients in achieving their sustainability goals. Our staff of over LEED accredited professionals stays attuned to the latest developments in sustainable design and construction through both in-house training and education and on-the-job experience.
