The ASHRAE Task Force on Building Decarbonization published the "Building Performance Standards: A Technical Resource Guide", which was developed to provide a technical basis for policymakers, building owners, practitioners and other stakeholders interested in developing and implementing a BPS policy.
Living Healthy & Indoor Air Quality
Evidence linking poorly ventilated buildings to heightened risks of airborne infection transmission
and subsequent respiratory and cardiovascular health issues, prompted a thorough reevaluation of existing IAQ standards. ASHRAE released its groundbreaking, highly anticipated publication, Standard 241, Control of Infectious Aerosols. The standard establishes minimum requirements for control of infectious aerosols to reduce risk of disease transmission in the occupiable space of new, existing, or majorly renovated buildings and includes requirements for outdoor air system and
air cleaning systems design, installation, commissioning, operation and maintenance, areas not similarly covered in existing IAQ standards or codes for buildings.
Green Transistion
ASHRAE has released a new standard to measure zero net carbon and energy goals in buildings.
ANSI/ASHRAE Standard 228-2023, Standard Method of Evaluating Zero Net Energy and Zero Net Carbon Building Performance, sets requirements for evaluating whether a building or group
of buildings meets a definition of “zero net energy” or a definition of “zero net carbon” during building operation. The standard draws from ASHRAE Standard 105, among others, to address energy and carbon flows across a site boundary, their measurement and their balance.
Opportunities Ahead
The HVACR industry is on the brink of a compeling era with abundant opportunities for innovation and growth. As buildings become more technologically advanced, the demand for skilled HVACR and built environment professionals who can navigate this evolving landscape will increaes.

A Changing Industry
Previously independent building systems had little need to communicate with other
systems or the outside world. Each system used their own communications protocol and
did not worry about cybersecurity, as they relied on obscurity for security. That approach
is no longer sustainable, so the industry is adapting. Cybersecurity is being designed
into building automation systems to support the overall cybersecurity goals of building
owners and operators. Every piece of equipment going into a building will soon have to be
reviewed for its cybersecurity threat surface and defenses.
Cybersecurity attacks will become more common and building owners and operators will look to their suppliers to provide solutions.
Industry Updates
Advanced connectivity and cybersecurity capability is reaching deeper into buildings and systems. With regulations and energy costs increasing, advanced capabilities are finding their ways into even end of line devices as we see manufacturers answer this demand.
Major Shifts
Demand for simple connectivity is waning in favor for more complex connectivity with inherent cybersecurity. Building Automation is more strongly focused on value.
Predictions
Cybersecurity attacks will become more common and building owners and operators will look to their suppliers to provide solutions.
Challenges
Building Automation struggles with not thinking big enough. A traditional focus on inbuilding equipment slows the adoption of sophisticated integration and cloud solutions.
The past few years have presented the industry many things to worry about. Regardless of
whatever the industry focuses on, the need to embrace an expanding, open, scalable, and secure base is paramount. Being able to communicate with multiple manufactures and systems with a common protocol is key.

A Changing Industry
I believe the industry as we know it now will be quite different in five years. Change is
happening fast for p-h-c businesses, as well as the industry overall. There will likely be
consolidations; more diversification of plumbing, HVAC and electrical companies; and more
new regulations and equipment. As this occurs, trade associations will need to transform
to meet members’ needs. A big challenge will be figuring out how to make sure their
members pay attention to vital information they share, such as the timing and impact of
new regulations affecting p-h-c contractors. No association wants to be asked: “Why didn’t
you tell us this was coming?”
Trending Topics
Finding, training and retaining employees is an ongoing challenge. It is difficult for contractors to keep up with and comply with the increasing number of regulations affecting the industry. Rising interest rates and costs seem to be becoming the norm. There still are some supply chain issues, but not as many as before. New technology, including Artificial Intelligence, continues to impact the industry.
At a recent PHCC Insurance, Safety & Risk Management Committee meeting, we discussed several
contractor issues identified by Corporate Partner Federated Insurance. They included cybersecurity,
driver security, changes in hiring practice, and general training needs.
Decarbonization
Earlier this year, New York became the first state to officially ban natural gas connections in new
construction and is following California’s lead in phasing out the use of gas and liquid fuel
appliances in the next decade. These are policies designed to leverage these states’ market power
to force a shift from products using carbon-based fuels to those using heat pump technology.
PHCC believes consumers know best how to power their homes and appliances. We support a diverse national energy portfolio that includes the use of gas and liquid fuel sources for appliances to ensure the quality of life on which Americans rely for their health and comfort
PHCC supports a diverse national energy portfolio that includes the use of gas and liquid fuel sources for appliances to ensure the quality of life on which Americans rely for their health and comfort.
The Inflation Reduction Act (IRA) includes a number of incentives for consumers and building owners to disconnect from fossil fuel sources of energy and fully electrify building infrastructure. The building sector is the second-highest emitter of carbon behind the transportation sector; IRA
incentives are designed to shift market demand away from fossil fuel appliances in order to reduce those emissions.
Tax incentives for homeowners include credits up to $2,000 to install qualified equipment and upgrade building envelope such as siding, windows and insulation, and deductions for building owners ranging from $0.50 to $5.00 per square foot for qualified HVAC and building envelope upgrades.
Rebates up to $4,000 (based on median household income) are available to homeowners for electric panel upgrades required to fully electrify a residence.
The Department of Energy and the U.S. Treasury have either published or are in the process of publishing guidelines to qualify for the incentives. Rebate programs will be
administered by state energy offices. Contractors are the interface with consumers and will
be performing the work demanded of the IRA as it is implemented. PHCC’s priority is to ensure contractors are prepared for this by ensuring they understand the nuances and complexities of how IRA programs work so that they can be properly communicated to consumers.

The current state of HVACR is bittersweet. On the one hand, the technology and innovation in the field is astounding and can only help professionals and end users achieve a shared goal of sustainability and energy efficiency. On the other hand, standard and regulation updates as well as mandated equipment options combined with supply chain issues and a very green group of professionals in the field is a daunting reality many business owners are facing. How can one industry possibly tackle all of these issues at the same time? Sadly, I believe it is going to take some major event failure in any one of these areas in order for everyone to pause and get on the same page again.
I have faith in this industry though, as it is incredibly resilient and is increasingly becoming an absolute necessity in the preservation of our food through the supply chain to our supermarkets and then homes, as well as maintaining comfort cooling and heating for individuals in their homes. RSES is looking forward to being a part of any dialogue that gets the industry working together and doing the right things for the right reasons, whether that is at AHR or beyond. Collaboration and flexibility will be important components to getting this industry back on track again. It is possible with the continued dedication support of all generations. The 2024 AHR Expo will give the industry an incredible opportunity to promote this dialogue while we are in the same space together, while also giving HVACR professionals the ability to see the latest innovations in products and services available in our field.
Sadly, I believe it is going to take some major event failure in any one of these areas in order for everyone to pause and get on the same page again.
Most Pressing Issues
Skilled labor/qualified technicians in the field are some of the most pressing issues. In addition, supply chain issues, costs for products, need for products and the lead times to fulfill customer needs/demands will continue to plague the industry.
Upcoming Opportunities
RSES Members stated that there are plenty of growth opportunities within specialized fields in the
industry. Another popular response was the continued encouragement of getting new HVACR technicians into the field. There is so much demand that everyone stands to make good money if we are able to close the skills gap a bit. This also generates the need for additional training/certification opportunities.
Challenges Ahead
Some did express a more negative side to what is taking place, which may be overregulation of an
industry that cannot keep up with demand, as it is, both with staff and equipment needs. Some additional individuals also suggested that many end users will not be able to afford new equipment even with government support in tax rebates/credits. Some additionally foresee issues coming up related to the new refrigerants and their compatibility with legacy systems. Additional concerns included the fact that HVACR professionals continue to be faced with an increased sophistication of new systems, coupled with decreased educational programs and some factory indifference about all of it.
