This project, targeting LEED Silver, consists of a hospital to support medical outpatient clinics, clinical and administrative support, education and research space, and outpatient mental health programs. The hospital provides urgent care, a new dialysis unit, diagnostic imaging services, a day surgery facility, chronic disease prevention clinics, seniors' wellness programs, and comprehensive care for women, children, and teens.

S + A Services Included:


The project features a geothermal field, along with heat recovery chillers, condensing boilers and very low pressure drop air handling systems (using oversized air handlers and oversized ductwork). The chiller plant consist of magnetic bearing chillers and geo-thermal heat pump chillers, the latter of which can be used to generate heating water for the building, or to store heat in the ground through the geo-thermal loop to be used at an appropriate time as determined by the building automation system. The heating plant consists of condensing hydronic boilers and heat from the geo-thermal heat pump chillers to feed low water temperature heating loops.

A dedicated outdoor air system (DOAS) serves the administrative spaces (non-CSA spaces) with dual duct variable air volume (VAV) boxes. Spaces with high occupancies have CO2 monitoring to regulate the volume of ventilation air supplied to the space. Enthalpy recovery wheels are used to pre-treat the ventilation air from the energy recovered from the breathable exhaust.


Electrical design services include the design and coordination of two incoming utility services terminating in medium voltage pad mount switchgear and medium voltage switchgear within the building. A unique main-tie-main auto transfer system on the 600V side of the main power transformers allows the system to detect a single utility failure, open the failed main breaker and close the tie breaker without the need to transfer to emergency generator power. The building is backed up by two paralleled diesel generators sized to accommodate the full building load. There are also two UPS systems, a 2N UPS system designed to support communications/network equipment and an N+1 system designed to support facility loads. The hospital utilizes 100% energy efficient LED lighting which is controlled by a networked addressable lighting control system. This provides occupancy sensing, daylight sensing, dimming and time of day scheduling features throughout the building. The fire alarm system is a two stage, zoned, non-coded fire alarm system with interfaces to clean agent protection systems, dry sprinkler systems and kitchen hood suppression systems.


Smith + Andersen provided audiovisual design services for various systems including: combining auditorium and classroom spaces with control room; telemedicine Studio; various collaborative meeting room spaces; digital signage systems throughout the facility to support wayfinding, patient information and IPTV. Notable technologies include fully integrated control systems, collaborative interactive display technologies, OTN and video conferencing technologies and a powerful CMS for the scheduling and distribution of digital signage content. Smith + Andersen will continue to provide project management, administration and commissioning support through the construction phase.
