Sheaffer, MIE; Noel Corral, MIE; Michael Chimack, MIE Prime Grant Support: University of Illinois at Chicago, Department of Facilities Management Problem Statement and Motivation The UIC Energy Management Pilot Study is geared towards identifying the level of energy consumption and cost savings that can be captured through energy efficiency upgrades and practices on the UIC campus. Molecular Biology Research Building (MBRB) on the West Campus Technical Approach • A complete walk-through assessment of University Hall (UH) and the Molecular Biology Research Building (MBRB) identifying all energy users • Simulation modeling of both buildings • Identification of energy conservation opportunities available for both buildings • Development of detailed cost savings to determine project paybacks • Verification of energy consumption of major energy systems through submetering • Projection of potential campus-wide energy savings using results from completed work Key Achievements and Future Goals The UIC Energy Management Pilot Study has been completed successfully and has provided the following results: • $470,000/yr total energy cost savings potential was identified for UH, corresponding to 47% of the building’s total annual energy cost • $525,000/yr total energy cost savings potential was identified for MBRB, corresponding to 19% of the building’s total annual energy cost • $17,000,000/yr total energy cost savings was projected for the UIC East and West campuses with a simple payback of less than 10 years Training Student Engineers Through Industrial Energy Conservation: The UIC Industrial Assessment Center Investigators: William M. Worek, MIE; Michael J. Chimack, MIE; Robert Miller, MIE Prime Grant Support: U.S. Department of Energy Problem Statement and Motivation IAC Student Conducting a Flue-Gas Test on a Plant Boiler Technical Approach A team of faculty, academic professionals and engineering students visits an industrial plant to conduct a one-day assessment. Opportunities are identified, quantified, analyzed, written-up and then presented to the client in a comprehensive report. Each recommendation is completely explained, with supporting information provided that is justified by calculations, measurements, industry information and vendor cost quotes. Six to nine months after the assessment, followup contact is made to determine which recommendations have been implemented, providing a measure of program effectiveness and feedback to the students on how they are impacting industry in a meaningful manner. The UIC-IAC promotes the training of young engineers in the understanding of the role of energy efficiency, demand and supply side energy management, and renewable energy practices in basic manufacturing systems and operations. The goals of the program are to provide engineering students with practical experience and training in energy engineering and assist small- and medium-sized manufacturers in identifying opportunities to reduce their energy usage with investment costs that reside inside their capital investment guidelines. Key Achievements and Future Goals • Since September 2000, completed over 120 assessments • Over 1,000 recommendations identified and quantified • Over $5.6 million in implemented savings realized by clients • UIC-IAC students have been awarded a number of university and engineering fellowships, scholarships and honors, including a Massachusetts Institute of Technology (MIT) Presidential Fellowship • Students in the UIC-IAC program have a 100% graduation and placement rate, with the vast majority of students accepting positions with employers well before graduation Energy Conservation in U.S. Army Industrial Facilities Investigators: William M. Worek, MIE; Michael J. Chimack, MIE; Robert Miller, MIE; Andrew Sheaffer, MIE; Jonathan Aardsma, MIE; Noel Corral; MIE Prime Grant Support: Construction Engineering Research Laboratory Problem Statement and Motivation Executive Order 13123 requires all Army industrial facilities to reduce energy consumption by 25% from their 1990 baselines by 2010. Many Army industrial processes are unique and the installations are unable to quantify, or control their energy consumption. Energy consumption baselines for each process must be established to measure efficiency improvements Welding on an Armored Personnel Carrier in an Army Arsenal Technical Approach The project proceeded along three separate lines: • An understanding of major Army industrial processes in terms of how they operate and how they consume energy was developed • Through research, site visits, and consultations, a consensus in defining the current state of the art of technologies related to the Army processes was developed • Data collection and analysis of contaminant emissions and ventilation within Army facilities was conducted in order to develop a better understanding of building process exhaust and thermodynamic principles In addition, an overall understanding of material demand and waste generation must be achieved in order to meet the Federal mandate, maintain mission readiness, and improve process efficiency. Key Achievements and Future Goals • A number of Army industrial processes were benchmarked against similar state of the art processes •Technologies for the Army processes were identified and examined to determine the costs and benefits of implementation • A software tool was designed to provide strategies to reduce harmful emissions in Army industrial buildings • System optimization control strategies were developed to optimize heating, cooling and ventilation loads • Studies of four Army facilities were conducted to demonstrate the benefits in efficiency improvements and energy savings that can be realized by adopting the technologies, tools, and strategies Energy Reduction Through Practical Scheduled Maintenance Investigators: Michael J. Chimack, MIE; Jonathan Aardsma, MIE Prime Grant Support: National Center for Energy Management and Building Technology and the Illinois Department of Commerce and Economic Opportunity Problem Statement and Motivation Clean Boiler Tubes without Scale • Commercial buildings spend $55 billion annually on Heating, Ventilating and Air Conditioning (HVAC) • More than 55% of companies use a reactive maintenance (RM) approach for equipment maintenance; while less than 33% of companies use a scheduled maintenance (SM) approach Dirty Boiler Tubes with Scale Technical Approach • Advantages of programmed SM include increased equipment life, improved indoor air quality and productivity, and a potential energy savings of 15-20% Key Achievements and Future Goals • A literature review was conducted to determine the status of the HVAC industry with respect to scheduled maintenance (SM) • Created a comprehensive literature review report. Potential savings in commercial buildings are estimated to be $8-$11 billion annually. • Unstructured, open-ended interviews of industry experts were conducted to determine the energy savings and other financial benefits of a proper SM program, and the reason why the clear benefits of proper scheduled maintenance are overlooked • Developed a Best Practices manual of SM protocols • Retraining the market through Best Practices seminars and webcasts will be conducted. Targeted attendees include building owners and operators, design engineers, HVAC contractors and apprentice tradesmen • Seminars scheduled for meetings of the Chicago Chapter of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) • First seminar given to major international property manager (responsible for 900 million square feet worldwide) Mechanical Systems Technology Evaluation Investigators: Michael J. Chimack, MIE; Jonathan Aardsma, MIE Prime Grant Support: National Center for Energy Management and Building Technology and the Illinois Department of Commerce and Economic Opportunity Problem Statement and Motivation • Commercial buildings spend $55 billion annually on Heating, Ventilating and Air Conditioning (HVAC) • Ventilation alone is estimated to consume 1.4 quads (1.0 E15 Btu) of energy annually • Conventional HVAC technologies can meet the needs of buildings, but are unable to efficiently meet the needs of higher ventilation air loads, humidity control, and varying occupancy densities Displacement Ventilation Technical Approach Key Achievements and Future Goals • A literature review was conducted to compare existing HVAC designs to the emerging generation of mechanical systems technologies (MSTs) • A literature review of 147 articles has been completed, identifying the road blocks to MST selection and implementation in HVAC specifications • Building simulation and other quantitative modeling tools will be utilized to identify proper applications for MSTs and to quantify associated energy savings and lifecycle costs • Next generation MSTs will improve indoor air quality and ventilation effectiveness, while reducing energy consumption in buildings • Educational materials will be developed to educate building owners and operators, design engineers and HVAC contractors on the costs and benefits of MSTs • Educational materials will include recommended actions to move next generations MSTs closer to application • Proper applications for MSTs will be determined by building simulation (climate and building type) • Educational materials and training seminar presentations will be developed to educate the market on the advantages and applications of MSTs including the recommended actions determined through the literature review and building simulations Commissioning and Retrocommissioning of Commercial Buildings Investigators: Michael Chimack, MIE; Christine Walker, MIE Prime Grant Support: National Center for Energy Management and Building Technology Problem Statement and Motivation • Though the benefits of commissioning (Cx) and retrocommissioning (RCx) protocols in the literature are numerous, they are principally anecdotal • Commissioning a building or systems within a building (e.g. decentralized heating, ventilating and air conditioning systems) is a method of reducing risk by ensuring that proper systems operation is achieved for the building owner • Quantification of the benefits of Cx is warranted Technical Approach Key Achievements and Future Goals • A literature review was conducted to determine the status of commissioning (Cx) and retrocommissioning (RCx) within the building and HVAC industries • The literature review is nearing completion • Building simulation and other quantitative modeling tools will be utilized to identify proper applications for Cx and RCx and to quantify energy savings potential • Educational materials and training seminar presentations will be developed to educate the market on the advantages and applications of Cx and RCx, including the recommended actions determined through the literature review and building simulations • Educational materials will be developed to educate building owners and operators, design engineers and HVAC contractors on the direct costs and benefits of Cx and RCx • Building simulation protocols for this project are being developed Evaluation of LEED Certification Program for Buildings A Case Study Investigator: Michael Chimack, MIE Prime Grant Support: National Center for Energy Management and Building Technology Problem Statement and Motivation LEED Buildings 180 160 140 Number of Projects 120 100 Certified Silver Gold Platinum 80 60 40 • The LEED (Leadership in Energy and Environmental Design) Green Building Rating System® is a voluntary, consensus-based national standard for developing highperformance, sustainable buildings • Very little empirical data exists that demonstrate the short- and long-term benefits of constructing a LEED building 20 0 USA India Canada Mexico China Current LEED Projects Worldwide Spain Technical Approach Select two identical or nearly identical buildings, one LEED (Leadership in Energy and Environmental Design) rated and one non-LEED rated, to monitor the following variables for a period of one year: •Temperature, Humidity, Carbon Dioxide concentration, Lighting levels and Power consumption of all pertinent heating, ventilating and air conditioning subsystems • Use building simulation software to normalize data for differences in building orientation, occupancy, equipment scheduling, etc. Key Achievements and Future Goals • Two City of Chicago buildings have been selected for the case studies • Preliminary building equipment assessments are complete • Monitoring equipment has been ordered.
