2010 technology awards Martin Roy, P.E., associate member ashrae Sobeys Warehouse industrial facilities or processes, new Peter H. Rumsey, P.E., fellow ashrae IDeAs Design Facility commercial buildings, existing Energy Efficiency. Based on DOE-2 simulation and compared to ASHRAE Standard 90.1-1989, the building energy consumption is 62% lower. Indoor Air Quality. CO2 sensors modulate the fresh outdoor rate, and a DOAS ensures each zone receives the correct amount of fresh air. Innovation. For cooling, the warehouse uses an ammonia central chiller. Natural lighting and heat recovery on the condenser side of the chiller for space heating are used. Operation and Maintenance. All refrigeration and heating systems are centralized in a mechanical room and water and glycol loops are equipped with balancing valves. All lighting control is also centralized, allowing for easy operation and automation. Cost Effectiveness. From the DOE-2 energy simulation, the energy savings are $144,896 and the simple payback is less than seven years. Environmental Impact. All plumbing fixtures are low flow, urinals are water-free and toilets are dual flush. Storm water drainage is canalized towards a constructed wetland acting as a retention reservoir. No wastewater is returned to the city. HCFC was not used. Energy Efficiency. Several energy efficiency strategies were used: HVAC, electrical system, and building envelope. Indoor Air Quality. A dedicated outside air handler operates continuously to provide 100% outside air to all occupied space during building operating hours. Innovation. The building uses several technologies, hydronic in-slab radiant heating and cooling, building integrated photovoltaics, and electrochromic glass to achieve zero net energy and zero carbon emissions. Operation and Maintenance. Ground source heat pump, building management system using DDC, reduced lighting requirements and reduced irrigation all help reduce maintenance and operation costs of the building. Cost Effectiveness. Photovoltaic panels cover the energy needs of the building saving the building $11,300 per year on energy costs as estimated from the baseline building, which leads to a 7.6 year payback on the PV system. Environmental Impact. The building location was chosen because it was on a previously developed site. No fossil fuels are used to create electricity for the building. A bioswale was added as well. second PlAce Ronald Gagnon, member ashrae | Louis-Stephane Racicot, P.E., associate member ashrae Logistik Unicorp industrial facilities or processes, new Cost Effectiveness. The project cost was $15 million ($81.38/ft2 Energy Efficiency. Energy efficiency was targeted at 25% below the Canadian model energy code, derived from ASHRAE Standard 90.1-1989. The simulated result, based on a complete EE4 (DOE-2) modeling, is 73.8% better than code. Indoor Air Quality. The system is designed for a minimum of 5,000 cfm (2,360 L/s) supply of outside air to a maximum of 9,000 cfm (4,248 L/s). All VOCs were eliminated or drastically reduced. Innovation. A hybrid system was designed comprising radiant slab cooling and low level air distribution coupled to a geothermal central plant. Operation and Maintenance. A BAS is used, which allows a single operator to control the entire building. March 2010 [$876/m2]). Annual energy savings are $450,672, with a return on investment period of 4.45 years. Environmental Impact. The building uses one third less energy than comparable buildings. Greenhouse gas emissions have been reduced by 656 metric tons per year. Brett J. Kelley, member ashrae member ashrae | Charles T. Meagher, associate Northwestern Memorial Hospital cGMP Cell Therapy Facility institutional buildings, existing Energy Efficiency. The air-handling unit is equipped with comparative enthalpy economizing, and VFDs control the supply and return fans, as well as the hydronic pumps. Indoor Air Quality. The facility was designed to meet ISO Class 7 in all cleanroom areas except for the cold room. ASHRAE Journal 57
