Advanced HVAC Equipment The INTENT of this innovation credit is to Encourage the use of Technologically & Environmentally advanced HVAC Equipement. The proposed REQUIREMENTS are to utilize systems that employee the use of Magnetic Levitation, oil-free technology within the moving components of the HVAC systems. The required SUBMITTALS would be to provide the LEED Letter Template, signed by the MEP engineer stating the magnetic levitation compressors were utilized on the project. The DESIGN APPROACHE utilized on this project was the use of 2 Turbocor refrigerant Compressors. Background: HVAC for the DPR/ABD Office Building will be provided by a 110-ton Mammoth evaporative condensing rooftop, packaged Air Handling Unit. The unit will contain 2 Turbocor refrigerant compressors. DPR Construction, the project developer, incorporated Turbocor compressors based on their superior life-cycle cost and reduced environmental impact. Why Should the Use of Turbocor Compressors earn a LEED Innovation Credit? 1. New technology, a risk to the project developer: Turbocor compressors utilize magnetically levitated rotor shafts, a technology never before used in the commercial refrigeration industry. The use of this new technology carries with it a degree of risk for DPR Construction: refrigeration failures could result in the loss of thermal comfort in the occupied space. Inability to maintain thermal comfort would result in loss of rent revenue. Due to the fact that building tenants pay for energy in typical, developer-owned office buildings, there\'s usually no motivation - on the part of building developers - to install high-efficiency equipment and thereby reduce building energy consumption. 2. Support of an emerging energy-efficiency technology: DPR\'s use of Turbocor compressors supports the commercial development of magnetic levitation technology, the application of which is in its infancy. In the future, "mag lev", oil-free technology will likely be employed in other building products such as pumps, fans, and air compressors. The future commitment of research and development capital will depend on the successful implementation current technologies. Turbocor compressors are one of the first commercial products that have employed the technology. 3. Energy Efficiency: Due to the absence of rotational friction, Turbocor compressors are far more efficient than standard compressors. IPLV ratings indicate that chillers driven by Turbocor compressors are approximately 35% more efficient than chillers that are driven by standard oil-lubricated screw compressors. Outstanding energy efficiency: The TT-300\'\'s competitive full load and outstanding part load efficiency enables HVACR OEM\'\'s to exceed ASHRAE 90.1 and California Title 24 energy efficiency requirements. At 100% load, Turbocor is more efficient, but 75%, 50% and 25% part load points are far more efficient. The dramatic difference in performance demonstrates the outstanding energy efficiency Turbocor compressors bring to HVACR products. 99% of HVACR equipment operation is at partload/off-design conditions. Integrated Part Load Value (IPLV) is the ARI Standard of comparison for the overall energy efficiency of HVACR products. 4. Environmental Impact: (a) When compared to a standard oil-lubricated screw compressor, a 75-ton Turbocor compressor reduces annual CO2 emissions by 28,512 kg. (b) Turbocor compressors contain no lubrication oil. The rotor shaft is held in position by magnetic levitation. The rotor shafts in standard refrigeration compressors are held in place by oil-lubricated bearings. Totally oil-free operation: No oil management hardware, controls or downtime costs. Improved heat transfer efficiency. Extended equipment life with minimal scheduled maintenance: Solid-state electronics, no lubrication and no metal-to-metal contact of rotating components. Onboard digital controls and power electronics: Enables effective monitoring, control and self-diagnosis/correction of system operation. Eliminates some traditional OEM control and power panel costs. 5. Material & Resource Conservation: Turbocor Compressors are 50% smaller than comparable compressors. They weigh 265 lbs. whereas conventional compressors can weigh over 1,000 lbs. Less natural resources are contained in Turbocor compressors. 6. Reduces Ozone Depletion: Turbocor compressors use HFC-134a refrigerant. 7. Additional Information: http://www.turbocor.com/index.html
