Engineered Systems Magazine’s January 2019 issue features the winners of the 20 to Watch: Women in HVAC contest, questions the feasibility of demand-controlled kitchen ventilation, examines the three sides of the combustion triangle, considers the nexus of ASHRAE Standards 90.1 and 62.1, and much more.
Industrial plants need steam for heating and other processes. Boilers are commonly used to provide this steam, and you may be called on to operate the boilers in your plant. The first step toward the safe and productive operation of boilers is a good working knowledge of boiler fundamentals.
Restaurants and commercial kitchens are notoriously one of the largest consumers of energy per unit of floor area. Moreover, the kitchen ventilation system is often the largest energy-consuming component in a food service facility.
The industry standard commissioning process includes development of a systems manual to supplement the equipment O&M manuals provided by equipment manufacturers. The systems manual is intended to document at least the following information about each commissioned system:
This month's Facility Files will focus on the Back2Basics test addressing the renovation of an existing Metro station with the addition of a new smoke evacuation system located within the building and within the subway’s inbound and outbound tunnels. The associated ADA-compliant elevator will have its own stand-alone, engineered, smoke control, 100 percent outside air fan to a positive-pressurized elevator shaft system.
Most of us have experienced one of our best solutions backfiring and unintentionally creating a bigger problem in the future. One historical example of an unintended consequence occurred in the early 1900s in Hanoi, Vietnam. Under French Colonial rule, the city was proud of the sanitation benefits of its indoor toilets supported by a vast sewer system.
We are starting a new year, and I believe the HVAC consulting engineers responsible for design engineering need to make a change in 2019 as to how HVAC systems are engineered to be safe.
HVAC and trade educators know the importance of students learning and working on equipment they will encounter in the field. This exact focus on experiential learning informed the plans for an expansive new trades teaching facility at Sheridan College’s Brampton, Ontario, Canada, campus.
The new Fork n’ Pint restaurant in Lake Orion, Michigan, installed front doorway air curtains in an effort to keep patrons and employees comfortable, resulting in more than $500 in annual energy savings and the elimination of $15,000 in potential vestibule construction costs.
The Lebanon Special School District (LSSD) in Lebanon, Tennessee, is one of the nation’s first school districts to retrofit conventional two-pipe classroom unit ventilators with combination VRF and ERV drop-in replacements.
Judges, prosecutors, law enforcement officials, and others who spend their days in and out of courtrooms in San Diego waited more than a decade for a proposed new state courthouse to become reality. According to designers on the project, their patience was rewarded.
In the summer of 2016, UBER Advanced Technologies Group (ATG) officially opened its doors in downtown Pittsburgh. As the main campus for UBER’s autonomous vehicle research and development labs, the building presented a unique design challenge.
Miki Minic knew immediately how to solve IAQ issues at a 227,000-square-foot Miami Class A office complex. The building engineer was in his first week with real estate company Jones Lang LaSalle (JLL) when he told supervisors he could significantly slash HVACR energy use at the 12-story Harbour Centre complex.
