Old homes and old HVAC systems bring the potential for asbestos — here’s what HVAC contractors and duct cleaning professionals need to know if they run into it on a jobsite.

If used correctly, AI can potentially enhance efficiency and accuracy across multiple industries, including HVACR.

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.

“Julie Petrone is an invaluable new partner in ASHB’s efforts to advance the smart technology industry,” said ASHB CEO Greg Walker.

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

The expected surge in smart thermostat sales will have equipment manufacturers, many of whom have their own proprietary controls, competing with the well-known universal thermostat brands, such as Nest, Honeywell, and ecobee.

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

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

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

The startup, Pascal, plans to build a better heat pump based on solid refrigerants that will deliver higher efficiencies at lower costs, while eliminating all refrigerant emissions.”

Industry figures are estimates that are derived from the best available figures supplied by a sample of AHRI member companies.

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.

This episode is an introduction to embedded system. It is an introduction in the sense that we cover many topics very briefly: upcoming episodes will provides details for many of these topics. We start by discussing what an embedded system is an what the important characteristics are. Among them is limited resources, concurrency, real time and hardware integration. We also discuss the range of embedded systems from small mirocontrollers to mobile phones to distributed real time embedded systems. We also cover the different business case for embedded systems (per unit cost) and some non-trivial developmental aspects (cross compilation debugging, heisenbugs). We close the episode by discussing some important architectural styles (time triggered, event-based, microkernels, state machines) as well as tools of the trade: languages, operating systems and middleware.

In this episode, Markus talks to Rebecca Wirfs-Brock on what she has learned from architecture reviews. This is a very complement to the earlier episode on architecture evaluation.

In this episode we have the pleasure of talking to Anders Hejlsberg, Chief Language Strategist at Microsoft. We started by discussing his more distant past, namely, his involvement with Turbo Pascal and Borland's Delphi. We then looked at the influences Delphi had on C# and how C# evolved from Delphi. In the next section we discussed a couple of general language design issues, among them components and checked vs. unchecked exceptions. Next, we discussed interesting issues about languages of the future, static vs. dynamic typing, functional programming, meta programming as well as the importance of good support for concurrency. We concluded the discussion by looking at the interplay between languages and IDEs.

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 we discuss the current state of the spring framework. We talk about core features (dependency injection, AOP) but also about the spring universe, i.e. some of the more specific frameworks such as Spring Batch.

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?
