Energy Efficiency & HVAC Technology

Consumers will frequently hear the term “energy efficiency” in conjunction with heating, ventilation and air-conditioning (HVAC) technology, but what does this term actually mean?  In recent years, HVAC appliances and systems have been recognized as a major untapped arena for promoting environmental health by improving the efficiency of these appliances.   Individuals can use energy efficient appliances and update their existing HVAC systems to reduce their environmental impact.

Understanding the connection between energy efficiency and HVAC technology requires an understanding of the environmental impact of HVAC appliances.  HVAC appliances are a major source of greenhouse gas emissions.  Greenhouse gases are those that are trapped in the atmosphere, causing what is known as the greenhouse effect.  In simple terms, the greenhouse effect causes a gradual warming of the earth’s temperature, and is a commonly cited cause of climate change and environmental degradation.

Emissions that lead to this type of degradation come from a variety of sources.  Industrial and commercial buildings are the leading contributor of greenhouse gas emissions.  However, individual residences also contribute to the buildup of these gases in the atmosphere.  Heating systems, air conditioners, and refrigerators are some of the appliances that have the most significant emissions in residential facilities. Despite this impact, the HVAC industry has made strides in developing more environmentally friendly HVAC technology.  New appliances, such as newly developed furnaces and refrigerators, are designed to produce fewer and cleaner emissions.

In addition to developing new technology to reduce the impact of HVAC appliances, residences can dramatically reduce their environmental impact by maximizing the energy efficiency of their existing HVAC systems.  Energy efficiency simply means ensuring that existing systems for HVAC are working well and without wasting energy.  Things like leaky or poorly insulated ducts can dramatically reduce a home’s energy efficiency, requiring more energy to maintain a comfortable indoor environment within a home.  Retrofitting appliances in a household can save a household a significant amount of money on energy costs, in addition to benefitting the environment.

The federal government in the United States has supported the adoption of energy efficient practices and appliances through the Energy Star program, a joint program of the US Department of Energy and the Environmental Protection Agency.  The goal of the Energy Star program is to help the United States reduce its environmental impact and save money on energy through the promotion of energy efficient practices and products.  Using energy efficiency guidelines, Energy Star certifies appliances that are up to standard to help guide consumers in making energy-conscious choices when buying new products.  Energy Star also publishes guidelines for new home construction projects or large renovations. 

Programs to promote the environment often suffer because there is no clear, immediate benefit to individuals.  However, energy efficiency for HVAC appliances is unique in that consumers will benefit greatly from updating appliances and systems.  Consumers will save money by reducing their energy costs.  Additionally, some states offer financial incentives to individuals and business who update their appliances.  The dual benefit of supporting the environment while reducing energy expenses will hopefully help to promote energy efficiency programs into the future.
