Manufacturers are finding innovative ways to meet and exceed expectations while creating comfortable, healthy indoor environments for building occupants.

While many in the industry are pleased the DOE has taken the opportunity to work together to develop its final rule, exactly how much of the working group’s recommendation the regulatory agency will adopt remains to be seen.

On Dec. 17, 2015, the U.S. Department of Energy (DOE) finalized new negotiated energy conservation standards for commercial air conditioners, heat pumps, and commercial warm-air furnaces, otherwise known as rooftop units (RTUs).

More than half of U.S. commercial building space is cooled by packaged HVAC equipment, according to the U.S. Department of Energy (DOE). So it comes as no surprise that energy efficiency is the biggest trend driving the rooftop market.

Aaon’s focus on serviceability and performance helped the WH Series earn gold in The NEWS’ 2017 Dealer Design Awards HVAC Light Commercial Equipment category.

Fujitsu’s Technical Service Advisors event was held to strengthen manufacturer-distributor relationships and empower in-field technical support staff.

HVACR technicians are special individuals. They have the intelligence, aptitude, and knack for problem-solving. In fact, they are expected to know how to diagnose and troubleshoot equipment of all types, sizes, and ages.

Summer cooling season is in full gear, which means that both technicians and their tools are being kept extremely busy.

Technological developments are consistently improving the tools technicians have to use.

Is reducing a facility's energy consumption by over 130,000 kWh annually through HVAC optimization possible?

With how cutthroat and competitive the HVAC market is, contractors must leverage data-driven insights and technological advancements to drive growth, attract ideal customers, and optimize customer satisfaction.

Here in the Santa Fe, New Mexico, area — and all across the nation, it seems — everyone wants to be “green.”

The Internet of Things is a broad term with multiple definitions, likely stemming from the different sectors of technology that IoT impacts.

BIM technology has proven to be highly expedient for several HVAC plans, especially in terms of cost efficiency, time optimization, and effective planning.

HVAC has a critical role to play in the future of building automation and digitalization.

While a controls upgrade may be costly, the reality is, the longer you wait, the more expensive a replacement can be.

This enables users to control their hydronic radiant panel, baseboard, or radiator to heat to the exact temperature and from wherever they may be.

From the start, the home’s development team at Legacy Custom Built Homes had big goals for the 6,600-square-foot, three-level home in terms of both efficiency and design aesthetic.

Products are emerging that help simplify homeownership.

What is the best approach to providing a holistic smart home experience for consumers?

If zoning technology was available before the pandemic, why has it taken so long for it to become an option that homeowners now consider?

Scandinavian green energy startup Aira plans to offer a 10-year service guarantee and a monthly fee that includes installation, maintenance.

While the installation of heat pumps may seem to be slowing due to inflation and rising interest rates, coupled with a confusing rollout of federal funding, they are expected to pick up speed this year.

Hybrid systems offer a pathway that balances environmental concerns with practical considerations, ensuring a more sustainable and feasible transition towards cleaner energy sources.

Purdue University researchers have designed a predictive thermostat for heat pumps that has been shown to significantly reduce electricity use.

To meet the ambitious environmental goals being proposed at all levels of government, residential air-to-water heat pumps are emerging as a transformative solution to lower carbon emissions, enhance energy efficiency, and reduce utility bills.

All-electric options have come a long way since their inception, and there’s never been a better time to get on board.

“(I’m Your) Heat Pump” is a soft, funky, R&B love song told from the perspective of a heat pump that depicts just what a heat pump can provide to its users.

This new private-public partnership wants to quadruple heat pump installation in California over the next 6 years.

Despite the arguments regarding the practicality of heat pumps in cold climates, residents of Maine have fully embraced them.

The equipment in this month’s troubleshooting problem is an electric furnace that has been in service for at least ten years and has no service history.

The ACHR NEWS visited Flame Furnace in Warren, Michigan to learn how to do maintenance and basic troubleshooting on a furnace.

The latest rule will require every mobile home gas furnace — and every new residential, non-weatherized gas furnace — to have a minimum annual fuel utilization efficiency (or AFUE) of 95% starting in late 2028.

Residential gas furnaces must all have a minimum AFUE of 95% beginning in five years. Some in the HVAC industry say the new Department of Energy rule will ultimately hurt homeowners.

Due to a lack of training, time constraints, and numerous other reasons, many HVAC contracting companies are not performing combustion testing, potentially compromising customers’ safety.

Using water to transfer heat energy into the home can minimize or even eliminate the issues of dry air and loud operation.

A homeowner in Pickering, Ontario works with an experienced HVAC pro to improve comfort, efficiency, and energy savings with a high-efficiency hydronic forced-air furnace upgrade.

Eric Evans is the author of the well known Domain-Driven Design book. In his day job he works as a consultant and coach for his own company, Domain Language. In this interview, Eric talks about the essential building blocks of domain-driven design as well as about a set of best practices on how to address complex projects. In a third part, he elaborates on the relationship of domain-driven design and MDSD/MDA.

In this Episode we have the pleasure of talking with Gregor Kiczales. Gregor is one of the fathers of aspect-oriented programming (AOP). Today he is a professor of computer science at the University of British Columbia. Back in his days at Xerox Parc, he and a number of other people worked on the early forms of AOP as well as on some of its forerunners, such as meta object protocols. In this interview, we talk about a number of interesting topics, such as the history of AOP, the relationship of AO to interceptors, the industry acceptance of AOP, early aspects (i.e. using AO in development phased before implementation) as well as adoption strategies for AOP.

Ruby has been getting more and more attention by the developer community over the last couple of years. Nevertheless Ruby as language and as a plattform is not too widespread. Most developers don't know people who have actually done commercial Ruby projects. Therefore it is sometimes hard to judge if Ruby is just a hype topic or if Ruby can be used for serious projects today. In this episode Alexander speaks with Thomas Quas about a commercial Ruby project Thomas finished a while ago. Thomas shares his insights and practical experiences with Ruby doing a project under strong time pressure. As Thomas has many years experience doing Java projects we also do some high level comparisons between both platforms.

In this Episode, we talk to Michael Stal, a Senior Principal Engineer at Siemens Corporate Technology, POSA 1 and 2 Co-Author and Editor of the german JavaSpetrum magazine. Since Michael's core focus is middlware, much of our discussion centered around that topic. Webservices and SOA, of course, have also been covered. Other topics include Java vs. .NET as well as Patterns.

SOA (Service Oriented Architecture) appears to be just another hype - after all we have been building distributed systems for quite a while now. But the real value of SOA is non-technical. In this episode Eberhard and Markus discuss the advantages and disadvantages, what SOA actually is and how it compares to other approaches that have been tried out before.

In this, as well as in the next episode Eberhard and Markus continue their discussion about SOA (the episode got too long, so we had to split it into two ... SOA 2a and SOA 2b). In this episode, we talk about the various perspectives on SOA (CBD, EAI, BPM), about fundamental requirements towards an SOA, and we discuss the role of models in defining sustainable architectures. We also discuss how a programming model based on the described approach typically looks like. We then discuss a number of issues any large-scale SOA faces (and for which the SOA paradigm does not really provide an out-of-the-box solution: In this episode we discuss data type ownership and (weak) typing of data types.
