Item MU's Energy Conservation Success [abstract](2009) Bassett, Eric; Coleman, Paul; University of Missouri (System); Missouri Energy Summit (2009 : University of Missouri--Columbia)Highly reliable and cost effective utilities are essential for the University of Missouri (MU) to achieve its academic, research, and outreach missions. MU's Campus Facilities - Energy Management department focuses on three key areas to help meet that requirement; Production Efficiency and Reliability, Energy Conservation, and Renewable Fuels. This poster presentation highlights MU's energy conservation program and the associated economic and environmental benefits. The annual utility cost avoidance from energy conservation measures has now reached $4.3 million. This is equivalent to three degree programs or $170 reduction in tuition per student. Since the program started MU has reduced energy use by 12% on a square foot basis. Based on EPA data, the corresponding reduction of CO2 emissions is equivalent to the removal of 18,000 cars from our roadways or the planting of 28,000 acres of trees. Following is a description of our program by energy saving category. * Lighting - Approximately 99% of the exterior lighting and over 90% of the interior lighting on campus has been converted to high efficiency lighting. Incandescent exit signs have been replaced with LED, reducing energy consumption by 80 - 90%. Daylight harvesting has also been used to automatically turn off interior lights in areas that receive sunlight. * Motion Sensors - Motion sensors have been installed in thousands of classrooms, offices, conference rooms, and laboratories to turn off lights and set-back thermostats when spaces are unoccupied. * Efficiency Upgrades of Building Heating, Ventilating and Air Conditioning (HVAC) Systems - Major HVAC systems have been retrofitted to higher efficiency systems, by upgrading the controls, motors, regulation of air flow, and use of energy recovery systems to reduce building energy consumption. * Design Standards for HVAC Systems - Energy efficiency design standards for HVAC systems are implemented on all campus projects to meet or exceed federal and state guidelines. * Energy Management Control System (EMCS) - The EMCS is an automated digital control system for HVAC systems, which monitors, controls, and reports energy use while maintaining comfort in campus buildings. Over the past 16 years the EMCS system has been expanded from fewer than 10 buildings to over 110 buildings comprising approximately 80% of the campus. * Reduced Building Energy Use and Analysis - All buildings are fully metered for energy consumption. Metering data is analyzed and energy consumption patterns are identified. Buildings showing a potential energy saving opportunities are audited and energy conservation projects are implemented. * Window Film - Window film has been installed on several buildings to reduce radiant heating during the summer months. * Chilled Water Loop - Over 17 miles of underground chilled water loop piping connects major campus buildings to form a loop, reducing the number of chillers required by 75%. * Campus-wide Energy Conservation Awareness - Faculty, staff, and students are encouraged to conserve energy through the use of advertisements, tours, and presentations.Item Renewable Energy Solutions for MU [abstract](2009) Coffin, Gregg; Hoemann, Paul; University of Missouri (System); Missouri Energy Summit (2009 : University of Missouri--Columbia)Highly reliable and cost effective utilities are essential for the University of Missouri (MU) to achieve its academic, research, and outreach missions. MU's Campus Facilities - Energy Management department focuses on three key areas to help meet that requirement; Production Efficiency and Reliability, Energy Conservation, and Renewable Fuels. This poster presentation highlights MU's efforts to develop and utilize renewable biomass fuels in its power plant for the associated economic and environmental benefits. The past several years MU has been testing and developing sources of renewable biomass fuels for use in its power plant. Biomass fuels tested to date include: corn cobs, switch grass, and wood waste. The plant staff has demonstrated that is can use blend up to 15% to 20% of sized biomass with coal in its existing stoker boilers. Most of the testing has been conducted with wood wastes; however we learned that most sized biomass fuels can be used in this same manner. This pilot program has been very successful demonstrating that MU is able to utilize renewable biomass fuels without increased cost, while also reducing emissions and investing in Missouri's economy. MU is continuing its use and development of biomass fuels in its power plant. Plans are underway to install a new material handling system designed to receive, store, and blend biomass in its existing boilers. Plans are also underway to meet MU's future energy needs with a 100% biomass-fired boiler. This new boiler will replace an older unreliable coal-fired boiler with a new bubbling fluidized bed boiler designed to utilize a wide range of clean burning renewable biomass fuels. Both these projects are in design and expected to complete in 2012. Why renewable biomass for MU? *Biomass fuel is a fully renewable energy available today. It's very cost effective and can reliably supply MU 24/7energy.* Biomass is abundant and plentiful in Missouri's forestry and agriculture industries. Biomass includes various wood waste sources, corn cobs, switch grass, waste paper, etc. * Using biomass will reduce emissions, including green house gas emissions. * Unlike fossil fuels, like coal and gas, biomass is a regionally supplied fuel for MU. Using biomass will allow more of MU's energy budget to be spent locally, resulting in more Missouri economic development and more Missouri jobs! * The use of renewable biomass in MU's power plant will help support MU's academic, research, and outreach missions by sharing knowledge and partnering to research new bio-fuel technologies.Item Efficient and Reliable Energy Solutions for MU [abstract](2009) Coffin, Gregg; Hoemann, Paul; University of Missouri (System); Missouri Energy Summit (2009 : University of Missouri--Columbia)Highly reliable and cost effective utilities are essential for the University of Missouri (MU) to achieve its academic, research, and outreach missions. MU's Campus Facilities - Energy Management department focuses on three key areas to help meet that requirement; Production Efficiency and Reliability, Energy Conservation, and Renewable Fuels. This poster presentation shows how MU employs efficient and reliable utility production technologies to meet its energy needs. Using various combined heat and power (CHP) technologies MU efficiently produces its own steam, electricity, and chilled water to meet the campus energy needs. These CHP technologies are highly efficient and cost effective compared to more conventional power plant technologies. Additionally, the CHP district energy plant provides MU with high utility supply reliability, essential for its research and medical facilities. Most power plant technologies waste large amounts of thermal energy resulting in low fuel energy utilization with most less than 38% efficient. The MU Power Plant uses highly efficient combined heat and power technologies which improves fuel energy utilization increasing the plant's thermal efficiency to more than 62%. This reduces the amount of fuel energy needed for MU's energy requirements, reducing cost and emissions. Key plant features and benefits include: * Co-generation steam turbine generators produce electricity from boiler steam before sending the low pressure steam energy to the campus for thermal use. * Waste exhaust heat is captured from the plant's combustion turbine generators using heat recovery boilers. This steam is also co-generated in the plant's steam turbine generators. * A balance of dual effect steam absorption chillers and electric centrifugal chillers in MU's district cooling system allows a more cost effective supply of energy during the summer months. * The CHP district energy concept along with fuel diversity provides MU with a highly reliable and cost stable energy supply that minimizes costs associated with typical energy market swings. * The high fuel energy utilization of CHP lowers fuel use resulting in emission reductions, including greenhouse gas emission, when compared to separate electric and thermal energy production. * The US EPA has recognized MU under its CHP Partnership program for effectively using CHP technologies to efficiently meet its energy needs while reducing emissions.
