Circumstances converged to construct a pair of plants on campus in a short timeframe. However, these projects weren’t identical twins by any means: different needs, locations, and other factors drove some major differences, from cooling towers to standby power.
Continuing on with Part 2 of the discussion on troubleshooting problematic HVAC systems and buildings, I want to get a little more detailed with how to grasp the big picture when starting out with problem solving an installation.
Air changes in some but not all spaces, duct liner here but not necessarily there, rooftop unit requirements … do the rounds and get a feel for the current condition of ASHRAE Standard 170, Ventilation of Health Care Facilities.
On all projects, the need to provide reliability, accuracy, and safety need to be carefully considered as part of the overall design, but when we start looking at critical environments, these requirements become paramount in the design process.
Luxury retail, data centers, retrofitted corporate space … they all had to meet 90.1. From lighting upgrades to custom coils on a factory chiller, explore specifics while absorbing the message to increase team integration earlier in the process.
ASHRAE 90.1, Energy Standard for Buildings, has served as a benchmark for both new and retrofit commercial building design for the last 35 years and continues to lead today’s sustainably minded business culture.
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.
