Building Efficiency - Energy Star qualified windows, doors, and skylights can reduce your energy bills up to 15%

ENERGY STAR™ qualified windows, doors, and skylights can reduce your energy bills up to 15% while helping protect the environment. Source: Energy Star

Energy use in commercial and industrial buildings in the United States contribute 45 percent of national emissions of the greenhouse gases linked to global climate change. Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are the principal greenhouse gases emitted to the atmosphere from the burning of fossil fuels to produce heat and power for buildings.

leaf Compressed Air

In the U.S. industrial sector, compressed air systems account for an estimated $5 billion per year in energy costs. Many industries use compressed air systems as power sources for tools and equipment used for pressurizing, atomizing, agitating, and mixing applications. Optimization of compressed air systems can provide energy efficiency improvements of 20%-50%. Source: US Department of Energy

Success Story


Fuji Film (PDF)

In an attempt to eliminate equipment failures and downtime issues associated with the plant’s compressed air system, FUJIFILM Hunt Chemicals U.S.A.’s in-house maintenance team worked with a team of faculty and students from the Tennessee Technology University Industrial Assessment Center (IAC) to conduct an assessment at its Dayton,Tennessee, facility to identify opportunities for improvement. Following the assessment, the team formulated an implementation plan that would increase the system’s reliability, reduce system maintenance costs, reduce the facility’s overall energy use, and eliminate the use of nitrogen when compressed air systems are down.

leaf Heating, Ventilation and Air Conditioning (HVAC)

Heating and cooling systems are the single largest consumers of energy in buildings with cooling occupying as much as one third of that electricity consumption.  Have your system inspected by a heating and cooling contractor before heating and cooling seasons. Making smart decisions about your business’s HVAC system can have a big effect on your utility bills. When replacing your heating and cooling equipment, look for the Energy Star.

Criteria for ENERGY STAR Qualified Light Commercial HVAC

For the purposes of Energy Star, light commercial HVAC equipment includes the following: air-source air conditioners, air-source heat pumps, and gas/electric package units. As mentioned above, both split system and single package units rated at 65,000 Btu/h or up to 250,000 Btu/h are eligible for the Energy Star label. As it is used primarily in commercial settings, three-phase equipment rated below 65,000 Btu/h may also qualify for the label. Source: Energy Star.

leaf Roofs

Americans spend about $40 billion annually to air condition buildings - sixth of all electricity generated in this country.  Energy Star qualified roof products reflect more of the sun's rays. This can lower roof surface temperature by up to 100F, decreasing the amount of heat transferred into a building. Energy Star qualified roof products can help reduce the amount of air conditioning needed in buildings, and can reduce peak cooling demand by 10-15 percent. During building design and when your existing roof needs replacement are both excellent times to consider reflective roofing. Source: Energy Star


Useful Resources for roofs

Green Roofs: A green roof is a vegetative layer grown on the rooftop. Green roofs have many benefits including reduced energy use, reduced greenhouse gas emissions, enhanced storm water management, and improved quality of life. For more information on green roofs, please visit the EPA’s Reducing Urban Heat Islands: Compendium of Strategies.

Success Story


Broward County Installs Highly Reflective Roofs

A total of 27,900 square-feet of highly reflective roof surface was installed on Broward County buildings to reduce solar heat gain in the air-conditioned space, increasing reflectivity from 12% to 78%. FPL's Building Envelope incentive is in process. The estimated environmental benefits include lower energy usage and GHG emission reductions.  The energy reduction for the installation of highly reflective roof and insulation is 73,336 kWh which is equal to a cost savings of $6,600.  This results in a reduction of 44 tonnes GHG emissions, which is equivalent to the annual GHG emissions from 9 passenger vehicles.  Source: Broward County Government Operations Group

Useful resources regarding windows, doors, skylighting

Energy Star qualified windows, doors, and skylights can reduce your energy bills up to 15% while helping protect the environment. View Energy Start windows and doors for Consumers section. 

Benefits Include:

  1. Save money and more!  Installing Energy Star qualified windows, doors, and skylights lowers energy bills and saves you money. With more efficient windows, you also use less energy, which reduces greenhouse gas emissions from power plants.
  2. Get Comfortable!  Do some of your rooms feel like a sauna in the summer? Put an end to overheated spaces. Energy Star qualified windows, doors, and skylights keep your home’s temperature consistently comfortable. A standard double-pane window allows approximately 75 percent of the sun’s heat into your home. With Energy Star qualified windows you can stay cool all summer long. Most Energy Star qualified windows reduce the “heat gain” into your home more than typical windows do, without reducing the visible light. You get the light you need without the uncomfortable heat
  3. Protect Your Valuables!  Many Energy Star qualified windows, doors, and skylights have a special coating on the glass that is like sunscreen for your house.
