Benefits of Mechanical Ventilation

Benefits of Mechanical Ventilation

Home  >  Remodeling & Improvement  >  Heating and Air Conditioning  >  Ventilation  > Benefits of Mechanical Ventilation

Moisture, odors, and other pollutants can build up inside a home if it does not have mechanical ventilation to provide fresh air. Mechanical ventilation systems circulate fresh air using ducts and fans rather than relying on airflow through small holes or cracks in a home’s construction assemblies (e.g., walls, roofs, or windows). Homeowners can breathe easier knowing their home has good ventilation.

The benefits of proper home ventilation include the following:

  1. Better Indoor Air Quality: Indoor air can be many times more polluted than outdoor air, yet the average American spends 90 percent of the day inside. Ventilation systems can significantly improve a home’s air quality by removing allergens, pollutants, and moisture that can cause mold problems. Mechanical ventilation allows for proper ventilation of your home resulting in your breathing cleaner air.
  2. More Control: When homes rely on air flow through construction assemblies for ventilation, the air delivery rate is unpredictable; and there is no control over the source or amount of air. In fact, air leaking into the house may come from undesirable areas such as the garage, attic, or crawl space. Mechanical ventilation systems, however, provide proper fresh air flow along with appropriate ...

Heating, Ventilation, and Air Conditioning

Heating, Ventilation, and Air Conditioning

Heating and Cooling

Heating, cooling, and ventilation accounts for about 39% to 54% of the energy use in a typical office. Larger offices have more cooling because of the internal heat gain from people, lights, and office equipment. Either way, heating, ventilation and air conditioning (HVAC) is a large part of energy bills. The purpose of an HVAC system is to heat, cool, control humidity, and bring fresh air into a building. Employee and customer comfort is the main priority. But saving energy doesn’t just mean colder spaces in the winter and uncomfortably warm spaces in the summer. As with lighting, it is generally possible to get better comfort while using less energy. HVAC systems are among the largest energy end-uses in commercial buildings. With greater energy use come greater opportunities for savings. Seven HVAC energy-saving options are:

Proper Operation

Turning your heating and cooling off when it’s not needed is a simple way to save. Just as lighting is frequently left on when no one is around, the same happens with HVAC systems. Having someone responsible for switching off the system can work, but introduces the possibility of human error. A better option may be an automatic setback thermostat. They provide the added comfort of a pre-warmed or pre-cooled office when you arrive at work. Setback thermostats don’t cost much and automatically adjust the settings up (or down) for evenings and weekends, eliminating the uncertainty and waste of manual control. Another opportunity with HVAC systems is adjusting the temperature settings to avoid overheating or over-cooling. An adjustment of only a degree or two can cut heating or cooling bills by two to three percent. Extending that to three or four degrees can produce savings of 10 percent or more. Try making small changes to find the optimal settings that maintain comfortable conditions for employees and customers. Allowing and encouraging employees to dress comfortably and seasonably will make them appreciate the changes more.

Proper Maintenance

Good equipment maintenance pays off in higher reliability of the equipment and reduced operation costs. Proper operation and maintenance (O&M) will uncover ongoing problems and eliminate nonproductive maintenance practices. Proper O&M is also important for energy performance. Aside from the obvious tasks like changing filters or calibrating controls, HVAC system maintenance can influence the energy performance of the total building. An overheating fan motor lowers the efficiency of the entire HVAC system. A leaking chiller pump will waste water, draw extra power, and also hurt the chiller efficiency.

HVAC Facts:
1. Daytime air temperatures can be three to six degrees cooler in tree-shaded
neighborhoods than in treeless areas.

2. Collectively adding up the millions of small savings achieved by energy-efficiency measures such as caulking and sealing c...

How to Create an Efficient Duct System

How to Create an Efficient Duct System

Home  >  Remodeling & Improvement  >  Heating and Air Conditioning  >  Ventilation  > How to Create an Efficient Duct System

To create a comfortable home, an efficient duct system is a must. Ducts—known collectively as the air distribution system—carry air from the central heater or air conditioner to each part of the home and back again. Up to 50 percent of the energy used to heat or cool air can be wasted if ducts are not sealed and insulated properly. That’s why the duct systems found in ENERGY STAR qualified homes are third-party tested for tightness and verified to be properly insulated.


  1. Improved Comfort: When ducts are properly sealed and insulated they deliver conditioned air more effectively to all rooms, helping to ensure a more constant temperature throughout the home.
  2. Lower Utility Bills: The average homeowner spends more than $600 on space heating and cooling each year. Tightly sealed and well insulated ducts found in ENERGY STAR qualified homes can reduce annual utility bills by $150 or more.
  3. Improved Indoor Air Quality. Leaky ducts in attics, crawl spaces, unfinished basements, and garages can allow dirt, dust, moisture, pollen, pests, and fumes to enter the home. Sealing these ducts helps improve indoor air quality.
  4. Lower Equipment Costs. When ducts are leaky, the heating and cooling system has to work harder to condition the home. Duct sealing, along with proper insulation, allows the installation of a smaller, less costly heating and cooling system.

Techniques and practices that provide an efficient and effective duct system include:

  • Ducts in Conditioned Spaces. Ducts operate more efficiently in conditioned air at room temperature. They do not work as well in excessively hot or cold attics and crawl spaces.
  • Sealed Ducts. EPA promote...
