1. Demand-Controlled Ventilation

    A tremendous amount of energy is wasted ventilating spaces unnecessarily. Demand-controlled ventilation regulates the amount of outside air drawn in based on a building's actual occupancy, and can save as much as $1.00 per square foot annually. Find out if this approach will be effective for you.

  2. Electric Heat Pumps

    Electric heat pumps are space-conditioning systems capable of providing heating and cooling in a single piece of equipment, which usually means energy savings and a lower capital cost. This article discusses heat pump operations and explains how to select the best model for your application.

  3. Electric Resistance Tank Water Heaters

    Despite being expensive to operate, many facilities install electric water heaters for their low initial costs and ease of installation. Find out what energy-efficient measures and alternatives are available to help mitigate the high costs associated with electric water heating.

  4. Energy Recovery Ventilation

    Proper ventilation is essential for maintaining good indoor-air quality, yet it places an additional burden on heating and cooling equipment. Energy recovery ventilation help save energy and improve humidity control.

  5. Gas Furnaces

    Residential gas furnaces offer commercial building owners higher efficiency and lower cost than commercial units do, and they also offer flexible zoning options. Learn about the available options for your building application.

  6. Gas-Fired Tank Water Heaters

    On a life-cycle basis, gas-fired tank water heaters are typically the least expensive means of heating water. Learn more about the different options available, and find out how to reduce energy use and maximize cost-effectiveness when considering a new or retrofit purchase.

  7. Heat Pump Water Heaters

    By pulling heat from the surrounding air, heat pump water heaters can more than halve your water heating costs. This article explains what you need to know about this energy-efficient technology and how to make the best choice when considering a new purchase.

  8. Monitoring-Based Commissioning

    Monitoring-based commissioning (MBCx) is a process applied to buildings to keep them performing at optimal levels. MBCx uses sensors and software in addition to standard retrocommissioning practices to provide a real-time account of systems within the building, often offering greater energy savings.

  9. Radiant Heating

    By heating objects directly, radiant heating can lead to energy savings because occupants usually feel comfortable at lower overall HVAC temperatures. This article discusses the various radiant heater configurations and performance so you can make the best choice for your application.

  10. Small Gas Boilers

    Residential boilers offer commercial building owners comparable efficiency at a lower cost than commercial boilers, and their relatively small size makes it easy to move them in and out of buildings. Find out whether a residential boiler is right for your building.

  11. Space Heaters

    Though they're generally considered inefficient energy hogs, space heaters can save energy and money in some cases. This article describes the types of space heater and discusses the applications in which they can provide savings.

  12. Tankless Water Heaters

    Tankless water heaters provide hot water without using a storage tank, resulting in higher efficiencies, smaller footprints, and higher life expectancies. Learn more about the benefits and drawbacks of this approach to water heating, and see if it makes sense for your building.

  13. Thermostats

    Programmable thermostats offer an automated way to reduce energy costs by turning down heating or cooling systems when a space is unoccupied. This article discusses how to use programmable thermostats effectively for maximum savings.
