Designing or redesigning a lighting system can be a daunting task. Chances are, if you hire an electrician to do this type of work, you will end up with whatever is on sale at the local supply house. When you hire CEG, you hire years of experience in designing and installing Energy Efficient Lighting Systems that work in the space they are located. Energy savings on lighting are broad, starting at 15% and going as high as 85%.

  • On average, if a customer has not had an efficiency upgrade in the past 10 years, they will be in the 60% to 85% range.
  • Customers who performed upgrades within the last 5 years can still achieve 30% to 40% savings.

Our commercial lighting retrofit services provide solutions to ensure superior energy efficiency by replacing outdated and inefficient light fixtures which can save up to 70%. We use photometric analysis and present you with a savings and payback analysis.

Geothermal Heating and Cooling Applications

Geothermal Heating and
Cooling Applications

Geothermal heating and cooling systems are a sustainable energy solution that harnesses the earth’s natural heat. They work on the principle that the earth absorbs almost half of the solar energy it receives, resulting in a consistent ground temperature year-round. Here are the main applications of geothermal heating and cooling we offer for our customers’ locations:

  • Residential and Commercial Heating and Cooling
  • Hot Water Supply
  • Industrial Processes
  • District Heating Systems Ground Heat Exchangers

These applications of geothermal heating and cooling help to reduce greenhouse gas emissions while also being incredibly cost-effective. They are cost-effective in the long run and provide a reliable and constant source of energy, irrespective of weather conditions.

Electric Motors and Drives

Central Boiler
and Chiller Plants

Central boiler and chiller plants are integral components of many large-scale heating, ventilation, and air conditioning (HVAC) systems. These components provide thermal energy to your building in the form of hot water or steam (from boilers) and chilled water (from chillers) for heating and cooling purposes.

Electric Motors and Drives

Electric motors and drives are key components in many energy solutions, as they convert electrical energy into mechanical energy and control this conversion process.

An electric motor is a device that converts electrical energy into mechanical energy. They are used in a wide range of applications, but most importantly to you, they are critical components in building appliances and HVAC systems. A drive controls the speed, torque, direction, and resulting horsepower of a motor.

Heating Venting and Air Conditioning

Heating, Venting,
and Air Conditioning

Heating, ventilation, and air conditioning (HVAC) systems are integral to maintaining indoor comfort and air quality in residential, commercial, and industrial buildings. As the name suggests, HVAC systems encompass three key functions: heating, ventilation, and air conditioning. Getting improved and efficient HVAC systems will drastically reduce your costs year-round, while also providing quality heat and air to your location.

Process and Process-Support Equipment

Process and Process-support Equipment

Processing and process-support equipment are vital components in various industries, particularly in manufacturing and industrial operations. If transforming raw materials into finished products or intermediate goods is important to your business, having up-to-date machinery is essential to operating cost-effectively and safely.

Energy Management Control Systems

Energy Management
Control Systems

Energy Management Control Systems (EMCS), also known as Energy Management Systems (EMS) or Building Management Systems (BMS), are computer-aided tools used to monitor, control, and optimize the performance of energy-consuming systems within a building or group of buildings. These systems are critical in managing energy consumption, reducing environmental impact, and maintaining comfort. We can update and install a modern EMCS so that you can control what type of use is best for your business.

Effective Energy Management Control Systems can also – and most importantly – lead to significant energy savings, improved building comfort, and extended equipment lifespan. However, it requires ongoing management and regular updates to ensure it continues to function effectively and keep up with changes in building use and technology.

Roofing Applications

Roofing applications in the context of energy solutions refer to various strategies and materials used in roof construction. Certain strategies and materials can help reduce energy consumption, improve building efficiency, and generate renewable energy. Some examples include:

  • Cool Roofs
  • Green Roofs
  • Solar Roofs
  • Insulated Roofs
  • Roofing Material

Roofing applications play a significant role in a building’s total energy performance. By considering energy-efficient roofing options, you can significantly reduce your energy costs and environmental impact.

Window Installation

Window installations in the context of energy solutions refer to the process of installing windows that are designed to improve energy efficiency and reduce heating and cooling costs. There are several key factors involved:

  • Energy-Efficient Windows
  • Proper Installation
  • Orientation
  • Window Treatments
  • Solar Control Glass
  • Replacement

By considering these factors in window installation, you can significantly improve your building’s energy efficiency, reducing energy costs and enhancing indoor comfort.

General Electrical Maintenance

Electric maintenance for commercial buildings encompasses a variety of practices that ensure your electrical systems are operating efficiently in terms of safety and energy consumption. Electrical systems that show even minimal wear and tear can become hazards and act as a drain on your energy consumption.

Key points of general electric maintenance include:

  • Electrical performance evaluations
  • Electrical systems/outlet optimizations
  • Cleaning
  • Code inspections
  • Battery replacements
  • Drive maintenance
  • Repairs where it’s needed
