Inside this nonprofit’s new headquarters in Portland, variable refrigerant
flow teamed with zonal heat exchange, 100% DOAS, daylighting, CO2
sensors, and more to deliver comfort while bringing actual energy
usage in under the design target of $0.83 per year.
The wave of acceptance for this design option continues to grow in North
America. Get up to speed on when and where chilled beams can have the
most impact. Then move into humidity control, supply air, system
sizing differences compared to VAV, economizers, and more.
For a nonprofit located on the shores of Lake Michigan and an adolescent treatment center in Minnesota, geothermal heat pump systems have been an upfront investment that pays off in terms of maintenance, ROI, and effectiveness within an integrated sustainable design.
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.
