Creativity, Deep Retrofits And Making Buildings Greener And Healthier

Newer buildings tend to be designed to be ‘green’, but what about older existing buildings, which still represent the largest share of environmental impact? There is more work to be done in the retrofit sector; and improving environmental performance of older buildings often involves ‘deep retrofits’ that are costly and impact multiple factors inside a building. In the COVID-19 era, there is also growing concern about needs such as circulating outside air, increasing hum...

Prepare for Prosperity by Recruiting and Retaining HVAC Employees Effectively

Hiring and retaining employees in the HVAC market is an ongoing challenge. The U.S. Bureau of Labor Statistics projects that employment of heating, air conditioning, and refrigeration mechanics and installers will grow 13 percent between 2018 to 2028, much faster than the average for all occupations. As the economic emerges from the COVID-19-induced slowdown, the industry’s workforce challenges will again be top-of-mind. Now is a great time for HVAC companies to update and expand their re...

AIM Act Would Provide Orderly Transition To HFC Replacements

The American Innovation and Manufacturing (AIM) Act of 2019 would provide an orderly national framework to guide replacement of hydrofluorocarbons (HFCs) over the next several years in the United States, with newer refrigerants that have less negative impact on the environment. HFCs are potent greenhouse gases with very high global warming potential. The future of the HVAC industry is tied to the manufacture of next-generation refrigerants and their adoption. Versions of the AIM Act – Sen...

An Outbreak Of COVID-19 In China Is Associated With Air Conditioning

Members of a family were eating lunch in a restaurant in Guangzhou, China, seated at a table below an air outlet and return air inlet for the central air conditioner. At another table sat a family who had just traveled from Wuhan, Hubei Province, China. There was another family seated at a third table. One of the diners experienced the onset of fever and cough later in the day and went to the hospital, later diagnosed with COVID-19. That was on Jan. 24, 2020. By February 5 – some 12 day...

HVAC Companies Respond to Essential Needs During COVID-19 Pandemic

Since the beginning of the COVID-19 pandemic, HVAC systems have been at the center of concerns such as indoor air quality and the need to minimize potential exposure. At the local level, HVAC installers have increased their efforts to keep equipment and supplies clean, and technicians are wearing gloves and masks as protection to keep customers safe. Many HVAC companies have also sought to give back to local communities hard-hit by the pandemic. As an industry, HVAC has remained committed to ma...

EPA Rolls Back Leak Repair and Maintenance Standard for HFCs

The U.S. Environmental Protection Agency has rolled back a standard set under the Obama administration to require leak repair and maintenance for industrial and commercial refrigeration and air conditioning equipment containing 50 or more pounds of hydrofluorocarbons (HFCs). The industry embraced HFCs, which are potent greenhouse gases, as a replacement for ozone-depleting refrigerants such as chlorofluorocarbons (CFCs). The requirements that have now been rolled back merely extended the leak p...

ASHRAE Opposes Advice To Disable HVAC To Fight Coronavirus

Which measures can lessen the spread of the novel coronavirus, and which can make it worse? As the pandemic continues to unfold, there is an overabundance of advice on the subject as it relates to HVAC systems. For example, one theory goes that air conditioning, by removing humidity from the air, may enable infectious droplets to linger longer than they would outdoors or in another space where humidity is higher. More humidity can weigh down viral droplets as they float through the air. Does i...

Using Biodiesel Blends To Improve Environmental Impact Of Home Heating Oil

A fuel called “Bioheat” is made by blending biodiesel made from organic and recycled products with ultra-low sulfur heating oil. The feedstocks used to make biodiesel include vegetable oils, animal fats, or recycled restaurant grease. About half the biodiesel produced in the United States is made from soybean oil. Blends are designated in percentages – a 5% blend of biodiesel with heating oil is B5, a 10% blend is B10, and a 20% blend is B20. Blends up to 5% are called &ldquo...

Honeywell Applies Machine Learning To Boost Energy Efficiency Of Buildings

Machine learning provides a tool to lower energy costs in a building, and Honeywell has launched a platform that incorporates the newer technology. Combining self-learning algorithms with building automation, Honeywell Forge Energy Optimization is a cloud-based system that analyzes a building’s energy consumption pattern and adjusts its settings. “We can help building portfolio owners fine-tune their energy expenditures to drive efficiencies and create more sustainable practices,&rd...

How Simplified Mobile Systems and Other Software Address HVAC Complexity

Mobile systems are growing in popularity across the HVAC market, driven by convenience and changing demographics of the workforce. For younger employees, smart phones are almost an extension of their hands. As they enter the HVAC workforce, they are eager to embrace mobile systems. However, the simplicity of mobile systems is also attractive to older workers, who may be less inclined to use a complex desktop computer system. In the case of mobile systems, “limitation leads to creativity,&...
