- Design Brief: Economizers
as they should and some waste a lot of energy. Better design,
controls, installation, monitoring, and maintenance can help
economizers meet their potential.
- Design Brief: Chiller Plant Efficiency
to install and more complicated to operate, a chiller plant offers a number of benefits over simple packaged cooling units, including greater energy efficiency, better controllability, and longer life.
- Design Brief: Indoor Air Quality
high indoor air quality and energy efficiency requires an
integrated design approach. There is a movement in the commercial
real estate industry to pay more attention to the issue of indoor
air quality (IAQ) throughout the design and construction stages of
a building's life.
- Design Brief: Centrifugal Pump Application and Optimization
perform many important functions to control the
built environment. The physics and basic mechanics of pumps have
not changed substantially in the last century.
- Design Brief: Air Conditioning & Ventilation
approach to building design, designers around the world have
succeeded at creating highly efficient air-conditioning systems
that provide excellent workspace comfort.
- 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.
- 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
- Design Brief: Central DHW Systems in Multifamily Buildings
especially in California's coastal towns. While each new
construction project will have a different ratio of energy end
uses, one can look at the existing building stock to get an idea of
how much is attributable to DHW systems. According to the
Department of Energy's Residential Energy Consumption Survey
(RECS), DHW accounted for around 32% of overall energy use for
existing multifamily units in the late 1990's.
- Design Brief: Acceptance Testing
of the Standards' ongoing effort to optimize
energy use in modern construction. It's intent is to address the
importance of proper system installation, as realized energy
savings from advanced systems depend on them being installed and
- Design Brief: Industrial Process Heat Recovery
in the industrial and
manufacturing sectors, and it often results in a large amount of
waste heat that is discharged into the atmosphere.
- Design Brief: Compressed Air
Despite its widespread application, however, up
to two-thirds of the compressed air systems in operation have
either an obvious problem that affects production or a hidden
problem that drives compressed air production costs higher.
- Design Brief: Automated Monitoring & Fault Detection
are all systematic methods of ensuring that a
building and its hardware perform to the level intended by the
owner and design team.
- Design Brief: Demand-Controlled Ventilation
that varies the amount of ventilation
outside air delivered to a space based on input from a single
carbon dioxide (CO2) sensor or group of sensors.
