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

“It's simple. If you want to encourage women to prosper and develop, provide them with some prospering women to inspire them to develop.”

GreenChill recognized nine supermarket and commercial refrigeration leaders for exceptional achievements to reduce the impacts of commercial refrigeration systems on the environment. 

With the election of Donald Trump to President of the United States, the HVAC industry is wondering how this will affect the Inflation Reduction Act incentives.

Low public awareness of incentives that can subsidize residential HVAC purchases means contractors have the opportunity to educate and position themselves as trusted advisors, marketing experts say.

Today’s commercial structures are full of sophisticated controls that have been changing building automation systems exponentially.

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

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

Trends at this year’s AHR Expo within commercial controls and building automation were improving energy efficiency, making buildings more adaptable, streamlining workflow to make things easier for HVACR contractors, and a greater emphasis on cybersecurity and digitization.

Studies have shown potential, and real, energy savings with the use of fault detection and data analysis to guide HVAC systems.

Since more companies are putting a focus on ESG principles, the HVAC industry is positioned to turn those goals, into a reality.

When it comes to comfort, not much beats zoning. In fact, many industry experts tout that once homeowners have experienced the comfort zoning has to offer, they will never own another house without it.

This product replaces standard supply registers with sensor-equipped registers that automatically measure each room’s dynamic conditions and optimally balance air distribution throughout the home.

This climate control solution ensures balanced, room-by-room comfort throughout the home.

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

Products are emerging that help simplify homeownership.

Quilt, a newly launched company, has introduced a ductless heat pump that they say simplifies the installation and rebate process, while offering transparent pricing.

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.

As more homeowners are ditching oil heaters and moving to heat pumps, the rest of the country can learn from the cold-climate success story.

Variable-speed heat pumps, which dominate the heat pump market in many countries, are getting more attention in the U.S. The NEWS asked several manufacturers about the benefits of the technology.

The DOE's new Rooftop Accelerator program encourages manufacturers to develop efficient commercial rooftop heat pumps for cold climates, which could reduce GHG emissions and energy costs by up to 50%.

With “heat pump” and “incentives” almost being synonymous at this point, contractors need to understand the basics to ensure customers are receiving the benefits.

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

BlocPower, a climate technology company focused on greening America's buildings, announced a fundraising round of $150 million, including more than $24 million of Series B corporate equity led by VoLo Earth Ventures and $130 million of debt financing led by Goldman Sachs.

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.

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.

Eberhard and Markus discuss the important topic of associations and dependencies in this show. While OO languages provide direct support for subtyping, most don't provide a first-class construct for other relationships between objects. The discussion elaborates on the problem and looks at various remedies, most importantly, dependency injection.

This is the first part of a series of Concurrency episodes. In this part Alex and Michael motivate and introduce the topic. We explain fundamental terms, such as thread, process, or mutex and dicuss typical challenges, such as deadlocks and race conditions.

In this second part of our concurrency series Michael and Alexander talk about basic patterns for concurrent programming, such as Active and Monitor Object, Scoped Locking and Futures. Further, they discuss some architectural considerations regarding the number of threads and resource usage in general. For more information, see the references for part one as well as the following links

The third part of our concurrency series by Michael and Alexander discusses how to build highly scalable servers. The discussion focusses especially on event-driven servers. As possible solution patterns a reactor-based design is suggested along-side several patterns for multi-threading issues: Reader/Writers Locks, Thread Pools, and Leader/Followers.

This is another episode where we mainly announce topics related to the podcast itself.

In this Episode we discuss fault tolerance based on the new book by Bob Hanmer. This is the actually the first part of the discussion, the remainder will be published in the next episode of SE Radio. We start by discussing some of the context for fault tolerant systems and the imperfect world assumption. We then discuss a number of terms we will need when discussing the fault tolerance patterns. We then discuss the fault tolerance mindset and connect fault tolerance to a number of related subject areas, such as software quality. We then discuss the shared context for the patterns that follow, among them the important observation that fault tolerance does not come for free! Finally we provide an overview over the different sections covered in the book and start the detailed discussion of the patterns by looking at the Architectural Patterns section. The next episode will discuss the remaining patterns in the book.

This is the second part of the discussion on fault tolerance with Bob Hanmer (if you didn't listen to Episode 77, which contains part one, please go back and listen now; this episode builds on that previous one!) We start by discussing a set of error detection patterns. Among are the well-known approaches such as checksums and voting. We then look at error recovery patterns, including restart, rollback or roll forward. The next section looks at error mitigation patterns, which include shedding load and doing fresh work before stale. The last patterns section then looks at fault treatment patterns. We conclude the episode with a small discussion about how to design systems using (these and other) patterns, and with some thoughts on why actually wrote the book.

In this episode we're talking to Jens Coldewey about his experiences in 10 years of introducing agile techniques to project teams. We discuss real-world examples and the lessons learned and strategies derived from them.

We start our discussion with a brief look at what Haskell is and how a pure functional language is different from non-pure languages. We then look at the basic building blocks and the philosophy of the language, discussing concepts such as the lambda calculus, closures, currying, immutability, lazy evaluation, memoization, and the role of data types in functional languages. A significant part of the discussion is then spent on the management of side effects in a pure language - in other words, the importance of monads. We conclude the episode with a look at Haskell's importance and community today.
