Cator, Ruma and Associates was hired as the Mechanical Engineer for this new 140,000 SF Greenfield building with a mechanical penthouse. The building contains a mixture of wet dry laboratories. The wet laboratories are fume head intensive including perchloric, hydrofluoric, and radioisotope exhaust systems. CRA implemented an intelligent high efficiency energy recovery system to far exceed typical laboratory energy performance. The project is targeting LEED Gold or Platinum.

Cator, Ruma & Associates provided the mechanical consulting services for the this project. This new Greenfield building is over 300,000 SF, and consists of chemistry laboratories, chemical engineering laboratories, biology laboratories, core laboratories including NMR, spectroscopy and vivarium. This building also houses classrooms and auditoriums. The building has a grand entrance with a café and a kitchen in the basement below the café. The main auditorium space is a single-story portion of the building. The south half of the main building is a five-story building including a basement, and the north side will be four stories and also include a basement. The top floors of both the north and south side are mechanical penthouses. The building was recently rated with a LEED® New Construction Platinum Certification.
The use of the following energy-efficient systems contributed to the required energy credits for the LEED® Certification:
▪ Low-flow, high-performance fume
▪ Heat harvester heat pump for additional heat recovery ▪ Water cooled chiller plant ▪ Direct evaporative cooling ▪ Water side economizer system ▪ Low pressure drop and distribution
design
▪ Wind tunnel modeling for optimizing efficient control and energy usage ▪ Condensing heating water boilers ▪ CO2 monitoring of high density spaces ▪ Low-flow plumbing fixtures (including
1/8 GPF urinal and dual flush toilets) ▪ Process cooling in lieu of
once-through domestic water cooling The building is set up with four laboratory neighborhoods. Each neighborhood consists of either four or five stories of laboratories. Partially redundant air-handling units are used in each, such that if one air handler fails, the other will be able to provide 60% of the required airflow to that neighborhood. The ventilation system consists of variable volume supply and exhaust to the laboratories, using pressure independent volumetric offset type Venturi Air Valves. All of the fume hoods are low-flow, high-performance type hoods to maximize energy performance.
The office and classroom areas are supplied with air from a separate air-handling system dedicated to
a Vivarium Suite, which is supplied by its own air-handling system with backup supply air provided from one of the laboratory air-handling units should the main Vivarium air-handling unit fail. The cooling system consists of a central chilled water plant (1,500-tons) in the basement, utilizing water-cooled chillers with a flat-plate heat exchanger for waterside economizer. The heating system is comprised of condensing boilers to supply heating hot water to the building. In addition, there is a steam boiler to provide process steam for sterilizers and other equipment. To increase efficiency between the heating and chilled water systems, a side stream heat pump is used between the chilled water return and the heating water return pipes to pre-heat the heating water return at the same time that it pre-cools the chilled water return, thereby always capturing energy recovery. The plumbing system consists of standard potable domestic water and industrial water for the laboratories. The hot water generation is accomplished with condensing hot water heaters. Other plumbing services include a re-circulating DI/RO system, laboratory grade compressed air system, natural gas system, and a vacuum system.

Cator, Ruma & Associates provided the design of the mechanical, electrical and plumbing systems and construction administration for this project. This new building is 35,000 SF and consists of offices and conference rooms.
A primary goal of the University of Colorado at Colorado Springs is to achieve a minimum 40% energy savings better than ASHRAE 90.1. This goal required a unique system since the ASHRAE baseline for an office building is already very efficient. The team incorporated a direct/indirect evaporative cooling air handling system to capitalize on the dry Colorado climate without refrigeration. However, the design included provisions for adding supplemental cooling should there be 10-12 days per year where the outdoor humidity is too high.
The electrical system incorporates general power, lighting, and lighting controls using occupancy sensors and daylight harvesting. Provisions were provided to add rooftop photovoltaic panels and supplemental cooling on the electrical system. The technology system incorporates audio/visual components in conference rooms and IT systems for all offices. Campus infrastructure upgrades for the IT backbone to that part of campus were included in the project.
