NEWS BRIEFS Boldt Company receives AGC award for upgraded Wisconsin hospital utility plant The Boldt Company was recently honored by the Associated General Contractors of Wisconsin with a 2012 Build Wisconsin award for work on an emergency department renovation project at St. Elizabeth Hospital in Appleton, Wis. The firm's rebuild of St. Elizabeth's 14,000-square-foot, threestory central utility plant was awarded under the "heavy/industrial/warehouse construction" category. Improvements and upgrades to the plant's systems included an ambitious vertical expansion over the existing plant and the installation of new boilers, cooling towers and generators that replaced the 50-plus-year-old previous parts. The upgraded plant is now better equipped to serve the hospital's campus, but also saves the hospital money through an estimated from 25to 30-percent reduction in energy use, along with less required maintenance work. HVAC partnership provides solutions for healthcare facilities HTS Texas has entered into an exclusive distribution agreement that will extend Apreco Limited's network. Through the partnership, HTS Texas will distribute and provide technical support for Apreco Limited's air pressure stabilizers along with air pressure relief vents and air pressure monitoring systems in Central, North and Southeast Texas. "Reliable and precise pressure control is something of great concern to building owners during the construction and/or renovation of sterile medical and critical laboratory environments," said Mike Donovan, principal, HTS Texas. "HTS Texas' partnership with Apreco Limited will position us to expand our operations to offer market-leading, air pressure stabilizing solutions to customers." McGrath completes challenging HVAC project at BarnesJewish Hospital McGrath & Associates recently installed a new HVAC system including three custom HVAC units at the Barnes-Jewish Hospital in St. Louis, Mo., as part of the renovation of the hospital's 36,700-squarefoot fourth floor intensive care unit. Unlike a crane-lifted rooftop installation, the HVAC units had to be delivered in sections by elevator to the fourth floor. The units were erected onsite in a space with limited floor-todeck height clearances. The main air-handling unit includes direct drive fans, hot and chilled water coils, steam humidification, air McGrath worked within limited floor-to-ceiling filtering and UV lighting for airstream clearances to install the HVAC system for the decontamination.

The exhaust unit also includes with pipe routed down to the fourth floor. an energy recovery system that connects McGrath followed strict contamination with the main air-handling unit to provide isolation and infectious prevention meaenergy efficiency. Chilled water pumps, hot water pumps sures to ensure a safe environment and clean air quality for patients and staff. and heat exchangers were installed on Swedish Hospital Issaquah chosen for cover of new ASHRAE energy guide Swedish Hospital Issaquah in Washington was selected for the cover of the 2012 edition of ASHRAE's Advanced Energy Design Guide for Large Hospitals. The design team for the project, which was completed in 2011, was challenged to: meet an energy target EUI of 150 in a region where the average EUI is 264, bring the hospital online one year earlier than traditional delivery methods could achieve and use fairly traditional engineering solutions to do so. CDi Engineers, University Mechanical Contractors and the design team collaborated to "design to an EUI" and 50 Medical Construction & Design | January/February 2013 used the energy model to monitor and guide the design and decision process on a daily basis. With an EUI currently tracking at 114, Swedish Issaquah has become the poster child for large energy-efficient hospital design. The hospital's systems focus on a central heat recovery chiller, low-static pressure HVAC systems with variable temperature setbacks, VAV on both supply and return and robust heat recovery systems. The low temperature condensing boilers are used only on peak demand days. In addition, the owner enjoyed significant participation from a local utility, Puget Sound Energy, which helped fund 98 percent of the energyefficiency measures for the project. www.mcdmag.com
