Learn how HVAC companies can increase retention by giving their employees a stake in the company’s success through phantom stock plans.

EPA is counting on increased recovery and reclamation in order to maintain existing HVAC equipment, and finally, the numbers are going in the right direction.

In the seventh installment of this series, we ask if there are any special storage requirements for A2L refrigerants.

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

NASRC has launched a workforce development program that focuses on recruitment, training, and retention, in order to combat the critical shortage of refrigeration technicians. 

With stronger global temperature fluctuations and demand for HVAC systems growing, heat exchangers are rapidly becoming essential to an ever-expanding market.

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

CABA was founded in 1988. As ASHB, its mission — to empower connectivity among people, spaces, and technology to deliver a more livable, sustainable, and efficient connected world — remains unchanged.

The lab is designed to give students hands-on experience that will help them bridge the gap between classroom instruction and the needs of employers.

HiberSense Inc. appointed Chris Lawson as channel sales manager for the U.S. market.

Zoning technology has experienced success in both residential and commercial applications of hot water and hydronic systems.

How many of standard HVAC sales include add-ons like a humidifier, air cleaner, HRV/ERV, UV lights, or zoning?

Contractors and HVAC technicians can create a wealth of opportunities by adding residential HVAC zoning to their list of services.

With cost reduction, sustainability enablement, increased comfort and performance benefits, VRF systems allow commercial buildings to gain a competitive advantage by reducing their carbon footprint and providing custom comfort to occupants.

His jacket was emblazoned with the logo of a manufacturer of high-performing heat pumps, but when I mentioned that we were thinking of getting one, the tech shot down the idea.

This e-book includes a summary of sustainable HVAC developments, in particular of heat pumps and refrigerant changes to address climate change.

Industry experts are telling contractors to stay informed and get involved with the new regulations that are likely to impact everyone this coming year

As heat pump technology advances and begins its march into colder climates, industry experts are expecting rooftop units to continue to gain popularity in both new construction and retrofits.

The decision is a win for the California Restaurant Association, which challenged the ban that took effect in 2020. The city has not decided whether to appeal.

The final rule from the U.S. Department of Energy, issued recently, requires newly manufactured indoor residential gas furnaces to be at least 95% efficient starting in December 2028, meaning furnaces made after then will have to be condensing models.

In this Episode, Alexander and Markus talk about scripting languages. Topics include the definition of what a scripting language is, typical usage scenarios, performance issues, programming styles and IDE support. In later Episodes we will talk about more specific topics, such as dynamic typing, reflection, functional programming as well as specific languages such as Ruby.

In this episode Michael and our guest Prashant Jain talk about patterns for resource management. Efficient management of resources is critical in the execution of any kind of software. Ranging from embedded software in a mobile device to software in a large enterprise server, it is important that the resources, such as memory, threads, file handles, or network connections, are managed efficiently to allow the systems to function properly and effectively. Michael and Prashant discuss various patterns, such as Lazy Acquisition, Caching, Leasing and Evictor and explain when, why, and how to apply them for effective resource management.

This episode is an interview with Werner Vogels, the CTO of amazon.com. We first talked about what scalability is, and which aspects there are to scalability. We then took a brief look at the technologies used at amazon, specifically, the middleware systems and the issue of vendor lock-in. Web services, and the role of SOA was the next topic. Then we covered what a service actually is add Werner explained the term "pizza teams". Testing and Deployment was the next topic followed by a look at architectural characteristics of scalable systems, the value of simplicity and the CAP theorem. We concluded the discussion with a brief look at the future of distributed systems

This Episode is a round table discussion about Ultra-Large Scale Systems. In 2006, a number of authors (among them our guests Linda Northrop, Doug Schmidt, Kevin Sullivan, and Gregor Kiczales) have produced a report that addressed the following question: Given the issues with today's software engineering, how can we build the systems of the future that are likely to have billions of lines of code? In this episode, our guests discuss many of the issues that arise from this kind of system and provide an overview of the research areas that should be investigated in order to tackle the challenge. If you want to get more detailed information, you can read the ULS Report (PDF).

In this Episode we talk about dynamic languages for statically-typed minds, or in other words: which are the interesting features people should learn when they go from a langauge such as Java or C# to a language like Python or Ruby. We used Ruby as the concrete example language.

We started the discussion about important features with the concept of dynamically changing an object's type and the idea of message passing. We then looked at the concepts of blocks and closures. Next in line is a discussion about functions that create functions as well as currying. This lead into a quick discussion about continuations. Open classes, aliasing and the relationship to AOP was next on our agenda.

We then looked considered a somewhat more engineering-oriented view and looked at the importance of testing and what are the best steps of getting from static programming to dynamic programming. Finally, we discussed a bit about the current (as of October 2006) state of dynamic languages on mainstream platforms.
