Technology: Exterior Lighting
Traditional wall packs typically serve as security floodlights in low-occupancy or secondary areas of institutional, commercial, and industrial properties; much of their energy use is wasted during unoccupied periods. Adaptive bi-level exterior wall packs offer energy, cost, and maintenance savings, and additional security by alerting occupants to the presence of others. Adding networked controls (verses using local fixture based controls) provides two-way communication over the Internet for system management of scheduling, dimming levels, energy monitoring, modifying fixture groups, generating automatic alerts, and other administrative needs.
Technology: Interior Lighting
A basic adaptive lighting system is composed of occupancy sensors, dimmable ballasts and sources, and a communication platform for the system components. By combining commercially available components, multiple solutions may be implemented to deliver occupancy-based, adaptive corridor lighting.
Technology: Heating, Ventilation & Air Conditioning
Evaporative condenser air pre-coolers provide an effective retrofit for reducing energy use in air-cooled chillers, RTUs and other DX equipment. These microprocessor controlled systems pass outside air over a wetted surface allowing heat to be absorbed by water evaporation thereby cooling the air stream before it reaches the condenser. Evaporative condenser pre-coolers are applicable to most climate zones, and have even greater energy impact in areas with lower humidity.

Ventilation controls are the only proven solution to decrease kitchen hood air flow when 100% capacity is not needed. Using a microprocessor and sensors, they reduce fan speed during idle periods and ramp it back up during cooking periods, to save both fan energy and conditioned air. These controls reduce the flow of air exhausted from commercial kitchens when 100% capacity is not needed, thereby reducing fan energy consumption and energy for heating and cooling make-up air.

The Aeroseal duct sealing system seals ducts remotely and often with reduced effort. The adhesive aerosol spray diffuses throughout the duct system, gradually building up inflexible seals at holes, cracks, and other leaks.

Retrofit efficiency optimizer controllers for single-zone rooftop-unit (RTU) air conditioners harness multiple energy saving techniques by replacing simplistic stock control units with digital controls, new sensors, and upgrading single speed supply fan motor to variable frequency drive motor controllers. These retrofits can reduce supply airflow to better match partial building loads, more carefully control outside air ventilation to the minimum amount necessary to maintain indoor air quality, and implement advanced economizer controls eliminating the need to operate the compressor when advantageous ambient conditions prevail.
Technology: Heating, Ventilation & Air Conditioning
One of the simplest ways to reduce the energy required by operating fume hoods is to ensure that the sash—the moveable pane in front of the fume hood that controls the exhaust flow from an experiment—is always in the lowest possible operating position. This simple action can in some circumstances lower the amount of energy used substantially and will in all cases provide for the safest working environment.

This version of the popular bollard incorporates high-efficiency LEDs and occupancy-based controls for maximum savings. The luminaire has improved light distribution and intensity control, and a robust vandal-resistant design. The bi-level feature not only saves energy and money, but also alerts occupants to the presence of others, thus increasing safety.

Technology: Interior Lighting
The smart bi-level stairwell luminaire meets lighting and safety code requirements for occupied interior stairwells, while saving energy by sensing occupancy at every fixture and reducing the lighting level during the many hours when no one is present. The fixture is practical for both new and retrofit applications, and it also can be used in other low-occupancy locations such as break rooms and hallways. Case studies show 40-80% savings compared with traditional products. Its simple payback period can be less than one year in new construction and one to two years in retrofits. The key components in the product are ultrasonic occupancy sensor technology, bi-level dimming controls, programmed-start electronic ballast, and a lamp conditioning circuit. The lower lighting level for unoccupied periods can either be preset or adjusted by users/contractors.
