Leaning on experience and data from various K-12 cities and projects, the authors pursue 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.
The Air-Conditioning, Heating, and Refrigeration Institute’s certification program now allows design engineers to verify the software outputs of certified liquid-to-liquid heat exchanger performance ratings.
What are the key technical challenges and design options for optimizing a geothermal heat pump design? Review the pros and cons involved with centralized or distributed pumping, with hybrid or decoupled systems, and with the controls that can guide them.
With the help of advances in intelligent controls and a shift in design mindset, these systems can steer buildings toward smaller equipment sizes and associated savings. Review three projects and consider the benefits of keeping an upcoming project in the loop.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
