Energy Retrofits for Existing Buildings

A full range of energy conservation measures could significantly reduce energy costs for your facility.

As a leader in energy engineering and construction, CEG works with building owners and managers to implement and finance energy upgrades in a wide variety of existing building types. We analyze existing systems within the facilities, and design and implement turnkey solutions that increase energy efficiency, enhance resilience, modernize equipment, and streamline operations and maintenance. We guarantee performance and leverage creative project financing to deliver comprehensive projects that meet sustainability, operational, and resilience goals.

Offices

At the average office building, approximately 30% of energy is wasted (according to the US DOE), most of it during peak-use times when energy prices are highest. Energy efficiency upgrades offer businesses an easy way to cut costs without reducing productivity. Typically, more than half of an office’s energy use relates to lighting and space conditioning, two areas where CEG is well-positioned to make an immediate impact.

Data Centers

Data centers and other energy-intensive facilities offer significant opportunities to improve efficiency and reduce costs. CEG has experience with existing data center retrofits, migrations, and consolidations, enabling us to deliver more energy-related savings while meeting current and future needs. Specifically, we employ an integrated “IT + Facilities” solution based on a coordinated, data-driven approach that addresses both IT and facilities infrastructure.

Laboratories

Laboratories consume energy at significantly higher rates than average commercial buildings. CEG’s portfolio of mission-critical projects includes a diverse group of projects implemented in fully-occupied and operational research facilities. We have the in-house development, engineering, and construction capabilities that are critical to the success of complex utility efficiency projects.

Industrial

Industrial facilities represent unique opportunities to bundle common energy conservation measures such as lighting controls and HVAC system upgrades with more ambitious measures such as renewable energy and cogeneration.

Retail and Grocery

To keep customers inside the store and to highlight merchandise, retail spaces must maintain a comfortable temperature and incorporate innovative lighting design. Unfortunately, these same lighting and temperature systems constitute over 80% of the energy expenditures for a typical retail store. Supermarket refrigeration and lighting represent 40-80% of total use depending on climate, making these systems the best targets for energy savings.

CEG can work with your facility to establish an energy-use profile and create a plan to reduce energy costs without sacrificing comfort or functionality.
