Technology Showcase of EEG

Daylight Harvesting Ballast reduces fluorescent lighting cost an average 40-50% in areas that receive daylight. When the ballast photosensor senses outdoor light, power is automatically reduced. Fixed level dimming is also available. Unique product eliminates expensive controls and wiring runs required for older generation technology.


LED Lighting offers advanced optics designed to enhance performance. The newest LEDs are little marvels that produce an extremely high light output per watt, often saving 70% on lighting costs. Guaranteed to bring on no greater than 10% lumen degradation over 5 years. The 21st century generation of digital LED features a superior Color Rendering Index (CRI) for true color, brightness and highest efficacy, providing greater savings with better lumen output per watt.


Induction Lighting uses gas discharge instead of electrodes for 50% energy savings. Rated 100,000 hours and guaranteed for 10 years, it has low starting temperature, 95 lumens per watt, is flicker-free and virtually eliminates maintenance costs. The fixture focuses illumination in a linear motion, ideal for parking garages, as light is not wasted illuminating walls. Special cobra-head design is ideal for street lighting too, concentrating light downward at night. Look up and you’ll once again see stars in the heavens.


Fluorescent Lighting Energy Manager is an energy-saving device installed at the lighting panel. It’s designed to reduce kWh consumption in fluorescent lighting systems. Typically, savings levels of 15% are achieved with only negligible foot-candle lighting loss. Proprietary algorithms in its microprocessor prevent the fluorescent ballasts in the lighting system from drawing power when that power can't be efficiently converted into light.


Turbocor Refrigerant Compressor System is a computerized, oil-free compressor system with VFDs and magnetic bearings that reduces energy use up to 50%. It has only one moving part, is quiet, virtually vibration-free, and is about 1/5 the weight and half the size of conventional compressors. Startup requires less than 2 amps, compared to 500-plus for conventional compressors. Turbocor operates most efficiency under reduced load when conventional compressors lose efficiency.


Diesel Emergency Generator Heat Pump takes over the function of block heaters and maintains stand-by temperatures of diesel generators. This saves 70% to 80% of the energy cost. The block heater typically maintains generator stand-by temperature, often from 90-degrees F and 120-degrees F. The heat-pump has an efficiency level 4 times greater than the block heater.


FANWALL System reduces energy cost up to 50% compared to large centrifugal or vaneaxial fans. FANWALL replaces old, inefficient, noisy, vibrating, low-reliability fans with a bank of high-efficiency fan modules that have VFDs built into a fan wall. Easily brought into an existing fan room, then assembled and installed into a fan wall, the System cuts sound and vibration, and provides needed redundancy, greater reliability and easy maintenance.


DeltaPValves® optimize HVAC hydronic system operation. These pressure-independent valves accurately control hot and chilled water flow, regardless of system pressure fluctuations. Dynamically balanced through all loads, DeltaPValves stabilize system flow and optimize coil heat transfer to reduce energy consumption. The simple selection and application process is complemented by a robust industrial-quality design and backed by guaranteed performance.


CO2 Sensor Building Ventilation Control System eliminates the high cost of using excessive amounts of outside air for fresh air ventilation. Outside-air level is pre-set at a fixed point for maximum expected occupancy. With variable occupancy, there is often up to 500% over-ventilation, wasting energy to heat or cool outside air. Sensors detect CO2 exhaled by occupants and adjust outside air to match needs of real-time occupancy.


CO Sensor System with VFDs reduces 80% to 90% of the energy costs when operating exhaust-fans in enclosed parking garages. Instead of running fans during all hours of garage operation, the sensor/VFD system operates fans at a low base level of ventilation and ramps up volume only as required if the CO sensors detect the presence of CO. This keeps air circulating and avoids turning fan motors on and off during the day for demand savings.


HVAC Ultraviolet (UVC) installs at HVAC coils to reduce energy cost, eliminate coil and drain pan cleaning, and greatly improve I.A.Q. All HVAC systems attract mold, which fouls coils and reduces heat transfer and air flow. UVC destroys mold, bacteria, and virus at the coil, returning heat transfer to near-original levels, eliminating coil cleaning, and improving IAQ to reduce absenteeism and improve productivity. Keeping coils clean can significantly improve efficiency and reduce energy cost.


HVAC Cycle Management (CMU) reduces energy costs of single-zone packaged HVAC, typically 12-18%. Packaged units with just an on-off thermostat operation run uninterrupted and are inefficient. CMU analyzes demand every cycle to determine when, and for how long, during each cycle the HVAC can "coast" with the fan running, while maintaining the desired temperature. The CMU does not affect the beginning or end of a call. CMU programming avoids short-cycling.


Hotel Key Card Energy System reduces in-room energy costs 20% to 45% by controlling energy use when a room is unoccupied. When entering a room, the guest places the key card in an entry-area slot to turn on HVAC along with selected lighting and power outlets. When a guest leaves a room, closes/locks the door and removes the keycard, HVAC, lighting and power outlets revert to energy-saving levels set by management, which always maintains guest comfort, even while sleeping.
