Designing, selling, and producing AHUs is a long process. Is there anything we can do to accelerate the process?

Seven of the awards include funding specifically for HVAC-related projects.

A look at how HVAC contractors can manage leads from the phone, website, and social media.

HVAC contractors can incorporate a variety of best practices to ensure fleet vehicles are kept running as much as possible.

Refrigerant regulations are another reason why change is coming, as HCFCs will be phased out by 2020, and given their high global warming potential (GWP), HFCs will likely be phased down in the near future as well. At some point, supermarkets will need to start considering low GWP alternatives such as HFO blends, as well as so-called “future-proof” refrigerants such as ammonia, CO2, or propane.

Much like subcooling, understanding and calculating superheat can be somewhat difficult for newbie technicians.

The bill significantly reduces the cost of a geothermal installation, spurs job creation, and hopes to inspire more contractors to tap into the geothermal market.

When changing the refrigerant within your pumping application, it is worth discussing the application with a process specialist.

There’s no doubt the connectivity of mobile devices has made our personal lives more convenient, but now they’re also helping make technicians more efficient, thanks to tool manufacturers developing wireless-enabled devices and test and measurement apps for download.

These compact datalogging instruments offer users a durable design with flexible programming configurations and the convenience of datalogging readings in Excel format directly onto an SD card.

When it comes to this piece of critical infrastructure, operators need to be prepared to face new and sophisticated attacks.

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

Michael Kircher and Markus Voelter introduce the topic of software product line engineering. They motivate when and why product lines are important to consider and what makes them so special. Further, they introduce some key terminology, such as platform, core asset, feature model, commonality, and variability.

Variability is one of the key concerns in software product line engineering. The episode introduces the concepts of structural and non-structural (or configurative) variability. It also discusses how to find and model variability, and especially how to implement variability in the solution artifacts. Michael and Markus discuss a series of variability mechanisms that can be used with today's programming languages and technologies.

In this episode Charles Krueger, a well-known member of the product line engineering community, talks about his long term experiences in the field. Charles is also the founder and CEO of a company that provides tooling for variability management and product derivation. Besides some clarifications on terms like product line architecture and reference architecture, you also learn what kind of preconditions need to exist before product line engineering can be applied successfully.

In this episode we're talking to Andreas Zeller. about debugging. We started the discussion with an explanation of what debugging and how it works in principle. We then briefly discussed the relationship between debugging and testing. Next was the importance of the scientific method for debugging. We then looked as debugging as a search problem, leading to a discussion about delta debugging, the main topic of this discussion. We concluded the discussion by looking at the practical usability of delta debugging and the relationship to other means of automatically finding problems in software.

In this episode we talk with Klaus Marquardt about building systems out of plugins. After briefly introducing the concept of a plugin in contrast to modules and related software engineering concepts, we discuss different views on plugins and different ways of working with plugins for developing software. We are looking at plugins for embedded systems as well as large business systems, at how plugins change the working mode and team organization, and discuss the possibilities of why and when to use plugins for implementing software systems.

This is the first part of a two part topic on roles in software engineering. Michael and Markus discuss role definitions in an corporate environment.

This is the second part of the two part topic on roles in software engineering. Michael and Markus discuss role definitions in a corporate environment. For several typical roles we give hints on the expected skills, knowledge, and mindset. In this episode we discuss the roles technical lead, technologist, requirements engineer, product manager, and project manager.

In this episode we talk to Christof Ebert about requirements engineering. As the name "engineering" suggests, we need to be systematic when working and managing requirements. Christof will structure RE into several activities, namely elicitation (identifying the relevant requirements), specification (clearly describing requirements), analysis (synthesizing a solution), verification and validation (achieving good requirements quality), comittment (allocating requirements to a project, product release or iteration), and management (keeping track of the implementation status of requirements). In this episode we discuss these activities and highlight lots of practical guidance.

In this episode Martin talks with Chris Grindstaff about the fundamentals of performance engineering. The episode discusses when and how to work on performance of client- and server-side systems, what you should take into account during development to avoid performance issues, typical situations that cause performance problems, and some common pitfalls when analysing performance.

Michael discusses with his guest Chuck Connell the differences between software engineering and computer science. What makes software engineering so unpredictable, with so few formal results? And how can we advance the field of software engineering without these results?
