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

Selling products online is a whole new ball game. So, contractors will want to learn about their consumers buying journeys, and thoughtfully consider how to launch the online store, what products to sell, and how to market it.

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

A visit to an ASHRAE event 30-plus years ago introduced David Heckler to VRF technology, and the distributor was won over. VRF systems now make up about half of his company’s business.

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

Controls-Con, presented by Cochrane Supply on May 5-7, 2021, discussed the impact of smart controls on the building industry.

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

Small- to medium-sized buildings make up about 94% of all commercial buildings in the U.S., according to the U.S. Energy Information Administration, yet only 13% of those buildings have a building automation system.

Here are some of the top benefits of commercial HVAC automation and how new technology may soon make automated systems even more valuable.

The market for automated systems in commercial buildings is growing rapidly, driven by increasing energy-efficiency goals, improving technology, and updated standards set by governments and professional associations.

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.

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.

Building automation systems can boost heating and cooling efficiency by more than 20%.

Home automation is no longer a thing of the past. Customers are seeking ways to intelligently control their homes in more ways than ever before, as evidenced by the number of new smart home products on display in this sector at the AHR Expo.

Contractors have numerous options for offering homeowners solutions in energy management systems.

At this year’s AHR Expo, Fujitsu presented the ways it can make the pandemic’s new way of living more comfortable.

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.

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

Only 4% of homeowners know modern heat pumps can heat down to -4°F. That’s a huge opportunity for HVAC contractors to step in and be the experts.

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.

One innovation leading the way in home comfort and efficiency is an air-to-water monobloc heat pump, which offers a blend of efficiency, sustainability, and cutting-edge technology.

This is the first episode (actually, episode zero) of software engineering radio. The episode does not contain real content, rather, Markus explains what the podcast is all about.

A very important area for Java are Enterprise Systems. With the advent of new technologies like Ruby on Rails, Java EE 5 or EJB 3 the landscape for Enterprise Systems appears to be changing a lot at the moment. In this episode Markus talks with Eberhard about what Enterprise Java actually is, why and where it is used. Based on that they discuss what the future might look like and how to make Enterprise Java shine in the future.

In this Episode, Arno, Bernd and Markus interview Jutta Eckstein. Jutta is a pioneer and expert on using Agile software development, specifically in larger teams. In the interview we talk about the agile manifesto, the role of personal relationships and trust in software projects, differences between agility in the small and in the large, as well as offshoring.

In this Episode we talked about the new POSA 4 book which has recently been published. We talk to two of the authors, Kevlin Henney and Frank Buschmann (the third author, Doug Schmidt was not available - and he had also been on the podcast a couple of times :-)). The book contains a pattern language for distributed systems. It contains 114 patterns that had been published before by many different other authors. The patterns have been rewritten to form a consistent language. We basically talked through the different sections of the book, which gives a really good overview over the challenges and the solutions of building distributed systems. These sections include From Mud to Structure, Distribution Infrastructure, Event Demultiplexing and Dispatching, Interface Partitioning, Component Patitioning, Application Contrl, Concurrency, Synchronization, Object Interaction, Adaptazion and Extension, Modal Behaviour, Resource Management and finally, Database Access. The book references several other previous works (as listed below). Interestingly, many of these referenced works and authors have also been discussed previously on the podcast. Here are the back references:

• Domain Driven Design, Eric Evans
• Messaging Patterns, Gregor Hohpe
• POSA 2 Patterns, Doug Schmidt
• Concurrency: Part 1, Part 2, Part 3 and the interview with Goetz and Holmes
• Remoting Patterns Part 1 and Part 2
• POSA3, Resource Management

This Episode is part five in our (probably ongoing) series on service oriented architecture. In this episode we talk to Nico Josuttis, who has recently published a book on this topic. As its title "SOA in Practice" suggests, it is a very pragmatic book based on Nico's experience as architect and project lead in a number of enterprise-level projects - not all of them had been called SOA, since they at the time the term was not yet coined. The episode discusses some technical aspects of SOA (such as loose coupling, messaging and ESBs), but mainly focusses on non-technical aspects of implementing an SOA.

In this episode we discuss the status of SE Radio today and introduce the team members. Among other things, Markus discusses stats, sound quality, partners, transcripts, and the cooperation with Hillside Europe. Also, the team members introduce themselves with a one to two minute clip.

In this episode, Dirk talks with David Frankel, resident Metamodeller and MDA expert at SAP Labs LLC, SAP's subsidiary in the Silicon Valley. Dave's extensive experience provides a big picture, from the early days of CORBA all the way to current issues that are bugging most enterprise architects' work with MDA.
