Michael D. Haughey, P.E., CEM, HBDP, LEED AP, Principal:
Mechanical, plumbing, fire protection design for new sustainable building. Design of ground-source heat pump system, heat-recovery ventilation, daylighting and occupancy sensors integration with mechanical, and demonstration solar photovoltaic system (Excellent Use of Renewable Energy in Buildings award from the Colorado Renewable Energy Society, 2002); Regional ASHRAE Award in 2003 for New Institutional Buildings category. Colorado Renewable Energy Society 2002 Renewable Energy in Buildings award for daylighting and mechanical engineering. Michael was the project manager for mechanical, daylighting, and electrical systems design.
Mechanical design for 50,000 sq. ft. elementary school HVAC system renovation and upgrade. Systems include new high efficiency condensing boilers, chilled water, and replacement of pneumatic controls with digital. Two options, air-cooled chiller and water-to-water Ground Source Heat Pumps were fully designed and bid as alternates.
Design of an ice thermal storage chilled water system serving a large middle school (honors (3rd place) society (international) ASHRAE award, 2003 for New Institutional Buildings category). The design is a unique “flexible pumping” and valve system that uses only the necessary pumping energy for the task at hand. The system monitors building kW and has the ability to modulate the chilled water and ice system components to avoid setting monthly utility kW peaks. The system monitors remaining ice and uses that in calculations that save ice for the end of the day.
Thompson Valley High School
Design of Ice Storage chilled water system and air conditioning addition for high school. The design is a unique “flexible pumping” and valve system that uses only the necessary pumping energy for the task at hand. The system monitors building kW and has the ability to modulate the chilled water and ice system components to avoid setting monthly utility kW peaks. The system monitors remaining ice and uses that in calculations that save ice for the end of the day.
Peer review for new high school. Systems include ground-coupled heat pumps, energy recovery ventilation, and a variety of measures intended to make this school one of the lowest energy use high schools in the State.
Loveland High School
Design for new ventilation system using custom rooftop air handling equipment to replace existing interior unit ventilator system. Schematic designs included a future ice thermal storage chilled water central plant for the school. Space and fan HP was allowed to accommodate future cooling coils in the air handling equipment. Roof-mounted ductwork in weatherproof enclosures were used due to lack of ceiling space. Sound attenuators, heavy gauge ductwork, and special detailing were provided for sound control. Heating water piping was mounted above the roof, anchored, and provided with expansion loops and guides. Numerous bid packages were provided to allow flexibility with the Owner’s budget. Specifications included detailed Commissioning requirements, which was performed by E-Cube, Inc.
Fairview High School Addition and Remodel
Mechanical design for the addition of an Instructional Materials Center (IMC) and an Auxiliary Gymnasium, plus converting the existing library into science classrooms and laboratories; rearranging and enlarging the existing science rooms; and converting a weight room into a women’s athletic locker room. Specifications included detailed Commissioning requirements, which was performed by E-Cube, Inc.
Schematic design services included recommending and evaluating shading options for west-facing windows with a magnificent view to reduce the mechanical system loads and equipment sizes to bring the project into budget.
Provided a study and report to Public Service Company of Colorado which was used to obtain Demand-Side Management (DSM) funds from the utility and matching funds from the school district Energy Program for the substitution of Indirect-DX cooling for traditional DX cooling.
HVAC for the IMC and Science areas is VAV Indirect Evaporative cooling and DX second stage with VFD’s on the RTU fans. The Auxiliary Gym is provided with Constant Volume Indirect Evaporative cooling. IAQ dampers were used to maintain minimum outside air quantities as an IAQ feature. The heat source is existing central boilers converted through heat exchangers to a glycol solution for the RTU coils. Updated the school district standard commissioning specifications, and commissioning was performed by E-Cube, Inc.
Heritage & Sunset Middle Schools: energy improvement designs
Engineering support services for design and construction administration of energy conservation measures including refurbishment of existing rooftop units (replacement of existing motors and addition of VFDs to the supply fan motors) and revision of the temperature control sequence
Oak Creek High School Addition and Remodel
Project Engineer for HVAC, Plumbing and Fire Protection design of new addition. The project included the expansion and conversion of a coal fired boiler plant from hot water to steam.
Clayton College Kitchen Remodel
Project Manager for HVAC and Plumbing design of complete kitchen remodel to add ventilation, hoods, make-up air and plumbing to upgrade for code compliance and expanded use.
Timnath Elementary School Addition and Remodel
Mechanical and electrical project management and design of mechanical, plumbing, and fire protection for kitchen, cafeteria, and flex room addition.
Lyons Elementary School Addition and Remodel
Mechanical and electrical project management and design of mechanical, plumbing, and fire protection for school renovation and upgrade. The renovation included the addition of a chiller, pumping, glycol system, air separators, etc., and upgrade of the control system to direct digital controls from pneumatic and system-powered controls. New controls sequences were implemented to conserve energy and improve ventilation.
