In this month’s troubleshooting situation, you are responding to a restaurant manager’s call for service, and the equipment is a walk-in freezer.

Compressor manufacturers have been improving the products on multiple fronts in recent months.

In the quest to build more sustainably, organizations have set forth a variety of standards to realize high-performance green buildings.

To realize high-performance green buildings, the place to start is improving HVAC – centering on ventilation/efficiency.

This low-voltage, slim-type inverter series was designed for energy savings and optimal control of fan and pump applications.

The U.S. Department of Energy’s (DOE’s) Building Technologies Office has released a request for information seeking stakeholder input on the design and construction of tenant spaces that achieve high levels of energy efficiency in commercial buildings.

Beginning July 3, 2019, the Department of Energy is requiring a maximum fan energy rating (FER) for furnace fans.

With a double brood of cicadas forecasted to awaken, now is the time to prepare for how to deal with the mess they will leave behind and the potential damage they can do to equipment.

Across seven product categories, LG’s HVAC solutions again pass AHRI's comprehensive performance certification program.

A variable speed drive (VSD) controls the speed of the high-torque, direct-drive motor for optimal fan operation.

Equipped with an Oilon LN30 ultra-low NOx burner and Nationwide’s Eagle PLC-based Control System, the 250 hp package boiler achieved average emissions performance of 5 ppm NOx and 0 ppm CO (corrected to 3% O₂) during third-party testing.

State and local regulations are driving new building construction as well as existing buildings to implement energy-efficient technologies in order to meet future carbon emissions reduction goals. These facilities, known as high-performance buildings, strive to deliver optimal efficiency, reliability, value, and comfort to tenants.

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.

The equipment in this month’s troubleshooting problem is an electric furnace that has been in service for at least ten years and has no service history.

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.

Senior performance architect and author of *Systems Performance* Brendan Gregg talks with Robert Blumen about systems performance: how the hardware and OS layers affect application behavior. The discussion covers the scope of systems performance, systems performance in the software life cycle, the role of performance analysis in architecture, methodologies for solving performance problems, dynamic tracing and tracing tools such as DTrace, the disk and file subsystems, the CPU and memory subsystems, and the challenges virtualization poses for performance analysts.

Kirk Pepperdine talks with Diomidis Spinellis about performance optimization. Topics include development practices, tools, as well as the role of software architecture, programming languages, algorithms, and hardware advances.

Casey Muratori caused some strong reactions with a blog post and an associated video in which he went through an example from the “Clean Code” book by Robert Martin to demonstrate the negative impact that clean code practices can have on performance. In this episode, he joins SE Radio’s Giovanni Asproni to talk about the potential trade-offs between performance and the qualities that make for maintainable code, these qualities being the main focus of Clean Code.

Lukas Fittl of pganalyze discusses the performance of Postgres, one of the world’s most popular database systems. SE Radio host Philip Winston speaks with Fittl about database indexing, queries, maintenance, scaling, and stored procedures. They also discuss some features of pganalyze, such as the index and vacuum advisors.
