For a consumer food group’s very mixed-space campus, HGA’s careful outdoor air strategy got support from smart boiler, chiller, and lighting design to create performance tailored for the client while comfortably exceeding LEED®and ASHRAE 90.1 requirements.
The ﬁnal air toxic rules for institutional, commercial, and industrial (ICI) boilers (after almost two decades of legal wrangling, political pandering and intrusion, and boiler-user dread) have been inked and will soon be published in the Federal Register - an action that will begin the compliance clock ticking for new and existing boilers in these sectors.
For almost a century, operators of boilers and steam using equipment have realized the benefits of higher process efficiency and extended equipment life made possible by reducing the feedwater dissolved oxygen (DO) levels to the lowest possible values.
Having lived with an ancient heating system and no cooling for years, a
Pennsylvania congregation now sings the praises of the updated
hydronics and new mini-splits that brought a mechanical renaissance
to the church’s various spaces.
From checking out valve chatter to maintaining optimal condenser water flow, consider a few quick reminders from the Northwest Energy Efficiency Alliance for a proactive, preventive O&M strategy to keep your water distribution system quiet and efficient.
School districts have known for quite some time that temporary equipment can assist in passing the tests of renovations or the pop quizzes of unexpected equipment failure. The lesser-known lesson is that having the plan in place can save significant time and money on top of the equipment’s basic benefits.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
