Recreation Facility

The building is approximately 40,000 square feet recreation facility consisting of two stories and a racquetball court.  The lower level houses the fitness center and the upper level is a full size gymnasium with two work out areas.

The project involved demolition of the existing steam boiler system and radiation, including remediation of asbestos piping insulation.  New system was a high efficient 95% efficient gas-fired boiler system with heating water radiation, cabinet heaters, and air handler coils.  The lower level renovated the existing air handler and replaced all supply and return ductwork.  Outside ventilation air was added to the air handler.  The gym had a 40-ton high efficient ground-mounted packaged rooftop unit with a heat recovery wheel and economized, with exposed spiral ductwork.  The racquetball court had a high efficient ground-mounted packaged rooftop unit connected to a plate and frame heat recovery unit.  The HVAC system is controlled by a digital control system.  Lighting was renovated to include high efficient T-8 lights.

A renovation of a 10,000 square feet 2-story warehouse space.  Turned the warehouse space into:

• Offices
• Work areas
• Secured storage

The HVAC system consisted of split-system, cooling only DX vav air handler and variable air volume boxes with electric reheat.  The system is controlled by a digital control system.  The lighting was high efficient T-8 fluorescent fixtures.  The workspaces were piped for compressed air and multiple power requirements.  A source capture exhaust hood and system was installed were grinding and welding is used.  Fire protection piping and heads were revised to reflect the new office and work area environment.

The east wing of the conference center had the HVAC system renovated.  The existing system was a variable air volume air handler, which did not allow for the diversity of the space.  This project removed a portion of the air handling system and installed a new high efficient, ground-mounted, packaged heat pump rooftop unit, with backup gas heat, and a heat recovery wheel and economizer.  Ductwork was concealed in a new chase and was distributed to new diffusers.  On the exterior of the building, the supply and return ductwork have connections for a standalone temporary unit to be added in the future.  The ground-mounted equipment was concealed by a special aluminum and steel fence that matched the architecture of the building.  The existing HVAC and mechanical systems were re-balanced and commissioned.  A new electrical system was added to power the new packaged unit and has a connection for a standalone temporary unit to be added in the future.

An energy audit of the Historical Society Building identified ten energy conservation measures.  DAE recommended night set-back, limiting steam demand, lower minimum variable air volume box set-points, time clocks for exhaust fans, reducing outside air, lighting upgrades, vending machine set-back timers, occupancy sensors in offices, restrooms and mechanical rooms, condensate heat and water recovery.  The energy cost payback and return on investment to implement these measures are 1.4 years and 69.2% respectively, which will result in a 20.9% reduction in energy costs.

An energy audit of the South Building identified eleven energy conservation measures.  DAE recommended generating chilled water on-site, night setback, limiting steam efficiency motors, lighting upgrades, occupancy sensors in restrooms and offices, and power factor correction.   The energy cost payback and return on investment to implement these measures are 3.8 years and 26.1%, respectively, which result in a 28.8% reduction in energy costs.

An energy audit of the Indiana Government Center, North identified ten energy conservation measures.  DAE recommended implementing light switch timers,  limiting steam demand, energy management system upgrades, balance air distribution system, variable speed drives for exhaust fans & air handler units, restroom occupancy sensors, lighting upgrades, high efficiency motors, and power factor correction.  The energy cost payback and return on investment to implement these measures are 2.8 years and 35.1%, respectively, which result in a 41.2% reduction in energy costs.
