air-source heat, heat recovery, LED lighting-the school board was able to take
advantage of generous incentives and maximized savings, which signifi cantly
reduced the project's payback period.
Tin Shui Wai Hospital | Suet Fai Leung, C.Eng., Member ASHRAE Tin Shui
Wai Hospital was built to meet the population growth and medical needs in the
New Territories West Cluster of the Hong Kong Special Administrative Region.
As the main medical institution in Tin Shui Wai, this hospital was designed not
only to meet the public and medical professionals' needs in respect of energyeffi
cient technology and renewable energy technology features aiming to reduce
operating cost and carbon emission but also designed with consideration of
indoor air quality, innovation, operation and maintenance, cost-effectiveness
and environmental impact.
University of Illinois Holonyak Micro and Nanotechnology Lab:
Renovation | Chad Luning, P.E. Member ASHRAE; Tim Jendrycki, P.E., Member
ASHRAE; Michael McDermott, Member ASHRAE; Kitty Knauz, Member ASHRAE;
Mario Zotta, Member ASHRAE The scale of the cleanroom HVAC systems at
Holonyak Micro and Nanotechnology Laboratory at the University of Illinois
at Urbana-Champaign is an imposing 500,000 cfm (235 974 L/s) design for
ISO 5 and ISO 6 microelectronics fabrication. The come-and-go occupancy of
the university research setting allowed the lab's design to integrate active particulate
monitoring with demand-controlled airfl ow to greatly reduce airfl ow and
energy consumption during nonoccupied hours.
Mitchell House Residence | Massinissa Ourtirane, Associate Member
ASHRAE As the fi rst of a series of projects at Bishop's College School in
Sherbrooke, Quebec, Canada, the Mitchell House Residence demonstrated the
feasibility and the benefi ts of a sustainable design at a cost-effective rate. The
energy consumption is signifi cantly lower than the baseline case due to the use
of geothermal systems, building management systems, high performance building
envelope, active chilled beams and heat recovery from exhaust air.
1801 J Street | Raymond D. Schouweiler, P.E., Member ASHRAE Key to helping
1801 J Street in Sacramento, Calif., meet its net zero energy, fossil free and
indoor environment goals was repurposing an existing basement into a thermal
labyrinth, which is used to precondition the ventilation air. The thermal labyrinth
is coupled with a VRF system and dedicated outdoor air unit with heat recovery
to heat and cool the commercial building.
Retrofitting with HTHV Heating
forges the Path to Net Zero
for warehouses & distribution facilities
* Reduce emissions with very low energy usage per square foot
* Benefit from improved IAQ from 100% outdoor air &
mechanical ventilation
