Although contractors were expected to witness better opportunities in the commercial HVAC system in 2020, the construction industry is declining.
FREMONT, CA: Construction contractors were optimistic about this year until the expectations for the sales began to crumble down. The non-residential construction spending saw a little reduction from last year with the private non-residential spending taking a hit for the retail and lodging sectors. The architectural Billings Index rebounded slightly in October after flat or declining billings in most of the year. Therefore the architecture firms stay optimistic about the future, despite the ongoing concerns about a potential economic downturn in the next year.
The recent stats indicate that housing began to show signs of declining. With few uncertainties about the home construction market, the non-residential sector might be the best focus of the HVAC industry in the upcoming years as the building owners continue to upgrade the heating and cooling equipment for energy savings.
Greater efficiency indicates the introduction of smart HVAC technology, which provides more control over the comfort systems, even remotely via mobile apps. Advanced algorithms enable equipment to learn the habits of occupants and to anticipate the occupant requirements.
Incorporating HVAC with other building systems like the lighting part of the building automation system is another ongoing construction trend toward increasing commercial buildings' energy efficiency.
The heating and cooling systems that use renewable energy like geothermal and solar are becoming more popular, as are the variable refrigerant flow equipment. Numerous manufacturers have introduced evaporative cooling systems with desiccant material to eradicate humidity from the cooled air before the building's distribution.
The heat pump systems continue to make the foray into the market. These technologies are curated to provide efficiencies in energy consumption as well as high performance. Few might cost more upfront, but the payback is energy savings can be substantial for building owners.
A natural refrigerant solution like carbon dioxide and ammonia is gaining ground in few areas, even though ammonia is not used in commercial applications because of its toxicity and flammability. This is primarily used in the industrial refrigerator.
