Nemours Children’s Hospital, Orlando, Florida : LEED Gold
This 60 acre pediatric healthcare campus includes a 95 bed hospital, attached outpatient clinics, as well as a dedicated central energy plant and stand alone parking structure. Located on a greenfield site, the buildings orientation is optimized along an east/west axis. The orientation of the design maximizes daylight to the interior spaces and minimizes undesirable solar heat gain. In addition to orientation, the project utilizes a combination of fixed sun shades, fritted glass, and low-e coatings to reject solar heat, reduce glare and improve patient comfort.
In evaluating sustainable design strategies possible for the project, the design team favored those initiatives that used passive vs. active technologies. Some of the passive design principals included in the design are daylight harvesting, high reflectance roof materials, roof gardens, and a terracotta rainscreen system. To maximize energy efficiency, several strategies were used for heat and resource recovery within the mechanical, electrical and plumbing systems.
In one instance, boiler sizes were reduced by use of a recovery heat pump chiller. This innovative device conserves energy by preheating water as it enters the boiler. In addition, gas modular condensing boilers were employed as an efficient, scalable solution to assist in the complicated energy demands of the facility. To conserve and reuse water in the facility, condensate water from air handling units is returned to the cooling tower, where it is mixed with reclaimed water used in the chillers.
As individuals, and as a team, we are motivated by clients who define sustainability as a requirement for their facilities. The goal of designing sustainable environments is energizing for our firm from a social, environmental and artistic point of view – from paperless communications and creative material use, to sustainable site concepts and innovative, energy-conserving construction techniques – we look forward to collaborating as a team to achieve sustainable goals.
