When the City of Tallahassee and Leon County collaborated on a consolidated public safety complex to deal with local emergencies, the stakes were high and the need for robust yet adaptable HVAC was, too. Another collaboration within the design — chilled beams and pump technology — represented a key component of the mechanical system as it stands ready for severe swings in occupancy and weather alike.
This chiller plant retrofit team encountered challenging existing conditions and an-swered with savvy choices for piping and valves as well as the chillers. Good communication, accurate documentation, and a creative bidding idea you might want to borrow also contributed to bringing the mechanical work in effectively and on budget.
The federal push toward break-even building energy is real, and the clock is ticking. The public sector will be flocking toward forward-thinking designs (and designers) like never before — prepare to rule more of the roost, or lay an egg.
The newly refurbished Kanata Leisure & Fitness Centre Wave Pool (KLFCWP) in Kanata, Ontario, gives HVAC engineers and contractors an unprecedented look into the challenges they’ll face in future natatorium retrofits.
Modular heat pumps, geothermal, energy recovery, demand control ventilation, an integrated digital control system, and more stretched out the sustainability and maintained a lean energy profile to serve local residents
At 35,000 acres, Denver International Airport (DIA) is the largest airport site in North America, and the second largest in the world. More than 53 million passengers travel through the airport annually.
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.
