  • Demand Response

    Demand Response

    Demand response (DR) is an energy management strategy that consumers use to temporarily reduce their loads during periods of peak demand. Whether their power (kW) or fuel (BTU/h) demand reductions are motivated by time-dependent rates, or to help maintain the reliability of the distribution system, DR strengthens the link between the price of consuming energy, and the cost of supplying it.

    Building owners and managers use DR to capture the significant financial, operational, and environmental benefits that can be realized when energy demand becomes more responsive to market signals.

  • Building Envelope Design

    Building envelopes not only provide the thermal barrier between the indoor and outdoor environment, but also play an important role in determining how effectively the building can utilize natural lighting, ventilation, and heating and cooling resources.

  • Lighting Design

    Good lighting design enhances architecture. Good energy efficient lighting design enhances both the design and the performance of buildings. Knowledge of the opportunities and constraints of available and emerging lighting technologies is key to success with this crucial design element.

  • Daylighting Design

    Daylighting - the practice of utilizing natural light within a building - requires careful planning to balance heat gain and loss, control glare, and adjust for variations in daylight availability. This design strategy can significantly cut energy use in buildings and has wide applicability to many different types of facilities.

  • HVAC Design

    A building's heating, ventilation, and air conditioning system (HVAC) creates interior comfort by compensating for climatic conditions. Many efficient HVAC system design options exist than those used in current practice and must be explored by designers pursuing high performance buildings.

  • Thermal Energy Storage
    Thermal Energy Storage TES

    The air conditioning system is the largest single contributor to a building’s energy cost during summer on-peak hours (weekdays, between Noon and 6 PM). In a typical system, the largest energy-using components are the chillers or compressors, which reject heat and provide cooled water or refrigerant to the system. Thermal energy storage (TES) systems utilize water chillers or ice-making machines to produce and store cooling capacity (thermal energy) for later use. Cooling capacity (energy) is produced and stored during the hours when electric energy demands and charges are lower, and the stored energy is used to cool the building when electric energy demands and charges are higher. Shifting cooling-related electricity consumption from on-peak to off-peak periods can result in significant energy cost savings, in addition to other benefits. Mature thermal energy storage technologies include ice storage, chilled water storage, and eutectic salts.
