Western Farm Bureau Building Renovation, Denver, Colorado
Evaluation leading to maintenance and repair of mechanical equipment including two chillers, and replacement of rooftop cooling towers for nine-story, 90,000 sf office building
U.S. Mint, Customized Industrial Process Efficiency Solutions Program (CIPES) Audit, Denver, Colorado
Energy audit involving investigation of mechanical equipment and identification of energy conservation opportunities. The project is part of the Public Service Company of Colorado Customized Industrial Process Efficiency Solutions (C.I.P.E.S.) program, giving emphasis to process loads with electrical demand savings potential. Fourteen potential Energy Conservation Opportunities (ECOs) were identified. Field measurements and calculations were performed to prioritize measures by potential costs and savings. Twelve ECOs were recommended with a combined total 7.4 year simple payback. Analysis and report included cost opinions, energy savings estimates, and summary of recommended modifications for each opportunity.
Kodak Colorado Division, Energy Conservation Program, Windsor, Colorado
Identification of energy measures site-wide, as well as opinions of probable cost to implement recommendations based on simple payback. Report included approximately 54 general categories of potential Energy Conservation Opportunities ECOs with about 60 additional subcategories or specific applications. 13 ECOs were evaluated that appeared to meet the 2 year payback goal. Adjustments made during the audit based on recommendations had simple paybacks of far less than one year. Analysis and report included cost opinions, energy savings estimates, and summary of recommended modifications for each opportunity.
Kaiser Waterpark I Energy Audit, Denver, Colorado
Identification of energy-efficient HVAC alternatives in 185,000 sf office building
Great West Life; Demand Side Management Proposal; Englewood, Colorado
Project Manager for preparation and submittal of a successful demand side management proposal to Public Service Company of Colorado. The project involves conversion to a hybrid gas and electric heating system and the use of high efficiency compact gas boilers.
2300 Riverside Building; Renovation Alternatives Analysis; Tulsa, Oklahoma
Project Engineer for troubleshooting and life cycle analysis of alternative solutions for 17 story luxury apartment building. The project recommendations included replacement of corroded piping, conversion of the three pipe system to a four pipe system, and chiller and boiler replacements. Additional improvements for an upgrade to code compliance included revisions to exhaust and make-up air systems. Each apartment had individual air handling units which needed coil cleaning and testing with a few needing replacement. Other alternative improvements included pump replacements, the addition of a hydronic free cooling cycle and a computerized control system for submetering and central control of mechanical equipment.
