- Design Brief: Advanced Variable-Air-Volume (VAV) Systems
Brief provides recommendations to help engineers improve the
efficiency of large HVAC systems. It focuses on built-up
variable-air-volume (VAV) systems in multistory office
- Design Brief: Drivepower
use of a drivepower system-which includes the motor, its controls,
and the connection between the motor and the equipment it
drives-designers need to consider how these components operate as a
system rather than looking at them on an individual basis.
- e-News #71: Evaporative Cooling: Saving Energy in More Ways Than Ever
by forcing hot dry air over a wetted pad. The water in
the pad evaporates, removing heat from the air while adding
moisture. Although the concept has been used in residential "swamp"
coolers in the Southwest for decades, technology advances have made
evaporative cooling a viable alternative to conventional cooling in
commercial buildings and in other areas of the country.
- Commissioning Assistant™
designed to provide project-specific building
commissioning information to design teams. The tool enables the
user to evaluate probable commissioning cost, to identify an
appropriate commissioning scope, and to access sample commissioning
specifications related to their construction project.
- ArchSIM Case Studies: Urban Promise Academy Uses Energy Modeling to Exceed CHPS Requirements
at the Urban Promise Academy consists
of approximately 11,000 SF of new construction including a
multi-purpose gymnasium with raised platform stage, office,
conference room, equipment storage, rest rooms, a lobby, and
art/music classrooms. The project is located within the Oakland
Unified School District.
- ArchSIM Case Studies: Modernization of Oakland High School Earns High Marks for Energy Efficiency and Comfort
consisted of major renovations in Building E (a
5,573 SF wellness center) and Building F (a 20,400 SF historic shop
building). In addition, the project included the construction of
one new building, Building G (a 16,320 SF classroom building). In
addition to the challenge of renovating aging buildings to provide
a healthy and productive educational environment, the design team
also had to meet stringent energy efficiency requirements.

is an award-winning not-for-profit
organization that has been serving low-income and immigrant
communities for 19 years.
- e-News #70: Revitalizing K-12 Schools for a Greener Future
finding the resources to renovate their
existing schools and build new ones while improving
conditions at the same time. Green design practices not only
minimize operating costs, but they can protect the health of
teachers. Green schools engage students in a learning environment
air is healthy, conditions are conducive to learning, and children
- Design Guidelines: Advanced Simulation Guidebook, Volume II
is intended to teach readers
about the high performance building process for commercial new
construction. The goal of the high performance building process is
to create buildings that meet owner and occupant needs in terms of
energy efficiency, thermal comfort, and other sustainability
areas-and do so in a way that reduces the necessary design effort
and construction cost impact.
- ArchSIM Case Studies: Coast Community College District Sees the Light
located in Orange County, California, comprises
three community colleges that enroll more than 60,000 students per
year in over 300 degree and certificate programs. Founded in 1947,
the CCCD enjoys a reputation as one of the leading community
college districts in the United States.

a corporate jet hangar with attached office
facility located at Burbank's Bob Hope Airport, set out with the
lofty goal to build the "most sustainable aviation hangar in the

integrated set of tools for design and operation of chilled water
- e-News #69: Chilled Beams
making their way to the U.S.
market. Chilled beam technology, which involves locating a
low-temperature radiator at ceiling level to cool the rising warm
air, has been utilized in Europe and Australia for more than a
decade. Once cooled, the air slowly descends into the occupied
zone, providing adequate cooling with minimal air movement and fan
power, while providing an unobstructed radiant heat sink above the
- Design Brief: Energy Efficiency Practices in Industrial Refrigeration
In new construction projects, significant energy
savings can be achieved by incorporating energy efficiency
technologies in the project design. For facilities being expanded
or upgraded, ensuring the efficiency of the refrigeration systems
can lead to significant energy savings without compromising
- e-News #68: Guestroom Controls for the Hospitality Sector
was San Francisco's first hotel to implement a cardkey
system to control lights and HVAC systems in guestrooms. Monitored
data from four rooms in the hotel showed a reduction in heating and
cooling energy of 45% during the peak cooling season. Computer
simulations based on monitored occupancy levels in the hotel
estimate a savings of 32% of annual heating and cooling costs.
Modeled across five different climate zones, the average savings
