An engineer with the 9th-largest school district in the United States writes about the IAQ testing and final report that his district commissioned. From offices to classrooms to cafeterias and restrooms, the monitoring was extensive. Read the results and some author comments about acceptable IAQ in schools, the possibility of overdoing fresh air, and the associated costs.
New filters and a monitoring system helped the Carolina Conceptions Fertility Clinic increase its success rate. Since Carolina Conceptions Fertility Clinic opened its doors in August 2006, it has become
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.
Review the work that engineers and clinicians put into creating an amendment
to the standard for relative humidity in the operating room and other
spaces. The goal was to see whether it was possible to adjust rh
thresholds without affecting patient health, but the associated
potential equipment savings may make facility budget directors feel
the best of all.
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.
Multiple dehumidification units allowed for scheduled downtime while maintaining this underground spa’s precise humidity requirements.The Grove Park Inn Resort & Spa is nestled in the Blue Ridge Mountains of Asheville,
A single-pipe system kept HVAC system operating costs low, even in the humidity-laden tropical air of Curacao in the Netherlands Antilles.When KPMG, the global audit, tax, and advisory services firm,
Chicago’s Michael A. Bilandic Building has 21 stories, one for each year since the previous retrofit. Recently, an open-minded project team paired modular chillers and hydronic gas boilers with pumps and VFDs to conquer some upgrade challenges, bring the mechanical system into the 21st century, and knock 15% off the tower’s measured energy use.
MEP designers need to re-examine energy wasteful DOAS
practices, which currently contribute to over-ventilation of occupied building space, and refocus on meaningful
decoupling of sensible and latent load control using dynamic outside air
management systems. Read more on the flexibility and possibility of the
author’s proposed solution in data centers, schools, and elsewhere.
