Littleton Regional Hospital

Littleton Regional Hospital, located in Littleton, New Hampshire, was founded in 1906. Originally located on Cottage Street, the original two-story brick building underwent many expansions during its 95-year tenure at that location. In January 2001 the hospital relocated to its new facility on the St. Johnsbury Road in Littleton, consisting of an 88,000 square foot hospital and an adjoining 25,000 square foot medical office building. Since 2001 the original medical office building has been renovated for other services, and a new 56,000 square foot adjoining Medical Office Building (MOB) was constructed; it went on-line in 2010.

Project Scope

Yeaton Associates, Inc. was secured to provide mechanical, plumbing, fire protection and sustainable design services for the 56,000 square foot Medical Office Building. The new addition contains a new entry to the hospital, exam rooms, an IT center, support spaces and conference spaces.

Project Result

As a result of an extensive energy analysis, Yeaton Associates, Inc. recommended that a ground source geothermal system be used for the 56,000 square foot addition as a means of providing an environmentally friendly, cost-effective approach to addressing the heating, cooling and ventilation needs of the new MOB. As such, Yeaton Associates, Inc. designed a 130-ton capacity, deep-bore, closed loop geothermal heating and cooling plant. Conventional HVAC systems and equipment, such as handling units with hot water and chilled water coils, were used in the design, fed by a water-to-water geothermal heat pump capable of producing simultaneous hot water and chilled water.  Since going on-line, the geothermal system has met expectations of energy effectiveness, cost benefit and building comfort.
