- Design Brief: Demand Response
that allows electricity consumers to receive financial compensation for temporarily reducing or rescheduling power use upon request. DR creates opportunities for building owners and managers to realize financial, operational, and environmental benefits by changing energy use patterns in response to market signals.
- Design Brief: Economizers
as much 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
both 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
System Design 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 buildings.
- Design Brief: Drivepower
the energy 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.
