COMMERCIAL HVAC

Commercial Heating and air conditioning (heating, ventilating, and air conditioning) systems, essential to the comfort of all indoor work environments, represent 40% of the energy used in commercial buildings throughout the country. The measures described below will result in improved heating and air conditioning performance and efficiency, and a substantial reduction in energy price.

STEPS TO TAKE BEFORE FIXING YOUR HEATING AND AIR CONDITIONING SYSTEM

Before making the choice to replace your Heating and air conditioning system, you might want to consider taking measures to reduce cost to maximize your present (and any future) system’s efficiency. Some recommendations are provided below:

  1. Seal Heating and air conditioning leaks and add insulation to improve efficiency.
  2. Control ventilation in sequence to be able to be able to conserve energy while maintaining a work environment.
  3. Purchase office equipment with minimum heat emission.
  4. Replace windows with ENERGY STAR qualified windows to improve efficiency. Install energy-efficient lights to reduce heat emissions.
  5. Prevent passive solar gain (i.e., a rise in temperature resulting from solar rays) via cool roof, window tints, etc. (On the other hand, measures could be taken to increase solar gain in cool climates.) Implementing the measures will ensure that you receive the maximum efficiency and energy expenditure benefits from installation of a brand-new heating and air conditioning system.

INSTALLING A COMMERCIAL HEATING AND AIR CONDITIONING SYSTEM

While essential to most indoor work environments, commercial heating and air conditioning services (especially cooling systems, in Texas) result in a considerable portion of commercial energy expenses. Nevertheless, systems are becoming consistently much more effective, with air conditioners consuming 30 percent to 50 percent less energy than models made in the 70s. In a decade, efficiency has improved so much that it’s possible to reduce cooling energy prices just as much as 20% by installing the latest system.

STEPS TO TAKE BEFORE INSTALLING A BRAND-NEW COMMERCIAL HEATING AND AIR CONDITIONING SYSTEMS: 

Take the actions outlined above to reduce load and maximize efficiency! Request an ACCA Manual N (commercial) or a Manual J (home), which will assist you to pick the right system for your area.  Don’t opt for a Heating and air conditioning system that’s too large for your own requirements. This may increase installation, maintenance, and energy price. To make sure that your Heating and air conditioning system is the right size, ask your Heating and air conditioning dealer to conduct an Air Conditioning Contractors of America’s (ACCA) Manual N Commercial Load Calculation. Contact us for help!

Ask your Heating and air conditioning dealer to provide quotes (including life-cycle prices) for both standard-efficiency and high-efficiency units. In case the high-efficiency unit’s life-cycle price is less than that of the standard-efficiency, then pick the high-efficiency unit. Pick only ENERGY STAR qualified Room Air Conditioners and Light Commercial cooling and heating components. Install energy recovery ventilation systems which repurpose energy from the exhaust air flow to condition air that is incoming.

If applicable (in humid climates), ask your Heating and air conditioning dealer about supplemental dehumidification to promote comfort and save on energy costs. If applicable (in arid climates) consider evaporative coolers to increase efficiency and save on energy costs. Install economizers to use air when the temperature is significantly less than the indoor air. Install and use programmable thermostats. Require utilization of National Electrical Manufacturers Association (NEMA) premium motors for Heating and air conditioning equipment.

COMMERCIAL SYSTEM CONTROLS

Additionally to reducing load and installing efficient Heating and air conditioning systems, implementing the appropriate controls is crucial to optimizing efficiency. Commonly, ENERGY STAR qualified programmable thermostats, system zoning, and CO2 detectors are used to control heating and air conditioning systems. While they’re ubiquitous on new heating and air conditioning systems, they might be used for systems.

ENERGY STAR QUALIFIED PROGRAMMABLE THERMOSTATS:

In addition, called a “setback thermostat,” they enable you to schedule temperature changes by day and time. In accord with the U.S. Department of Energy, the proper use of a programmable thermostat can reduce energy costs up to 20 percent.

System Zoning: Dividing space that is available into zones, or areas, allows temperature control from each zone and takes care of the problem of temperature inconsistencies. When correctly used, it cuts down on energy costs.

CO2 Sensors: Important to monitoring CO2 and overall indoor air quality increase system performance and save on energy costs.

HEATING AND AIR CONDITIONING MAINTENANCE 

Regular maintenance is significant to an efficient and reliable Heating and air conditioning system. To promote your system’s longevity, the following is recommended:

  • Replace air filters on a regular basis to reduce operational stress.
  • Clean the evaporator and condenser coils on your air conditioning, to promote heat transfer.
  • Address duct leakage or ensure that you’ve ample insulation, to prevent loss of cool air and promote system efficiency.
  • Repair valves and steam traps to reduce energy expenses.
