Demand-controlled ventilation (DCV) is a control strategy 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.

The Tahoe Center for Environmental Sciences (TCES) is a three-story, 45,000 ft2 building on Sierra Nevada College's Lake Campus that demonstrates how an ambitious project team can successfully reduce energy usage by implementing a variety of innovative mechanical designs at minimal additional first cost.

Demand response (DR) refers to a mechanism that encourages customers to reduce or shift their electric power usages under certain conditions to help utilities to overcome temporary constraints in the electricity supply.

On average, energy management systems save about 10 percent of overall annual building energy consumption. An energy management system (EMS) is a computer that controls the operation of all major building systems, in order to run the building efficiently and effectively. An EMS can reduce a building's overall energy use by about 10 percent.

By using recommended design methods for rooftop heating, ventilation, and air conditioning (HVAC) systems, significant improvements in operational savings, energy efficiency, and indoor comfort can be achieved.

Underfloor air distribution and access floor systems can provide energy savings, improved indoor air quality, and a technology ready environment for today's commercial buildings.

Displacement ventilation provides improved IAQ, cooling energy savings, and better acoustics for high performance buildings.
