Dr. Hershkowitz Medical Office, Port Charlotte, Florida
THE NEW MEDICAL OFFICE BUILDING designed for Dr.
Douglas Hershkowitz’s neurosurgery practice is a
7,500 square foot, single story building placed
on a previously developed one acre site on U.S.
41/Tamiami Trail in Port Charlotte, Florida.
While the design of the building evokes a very
traditional Mizner Mediterranean aesthetic,
energy optimization, including use of renewable
energy sources, provides the building with a
high performance, green building component. The
polygonal shaped site, coupled with a dedicated
access easement through the site, and the local
jurisdiction’s parking requirements for
healthcare occupancies and minimal front setback
requirements, severely limited the options for
placement of the building on the site.
The design of the building and site are
conceived to contain and treat a high percentage
of site water and utilize roof top rainwater and
roof top HVAC condensate water for landscape
irrigation. The dumpster foundations provide the
cistern for the storage of rooftop and
condensate rainwater for irrigation; an outfall
from the cistern to the sub-surface storm water
structure is to be provided. All hardscape storm
water will be fully contained on the site in
surface and sub-surface storm water management
areas/structures. High solar reflectance index
(SRI) concrete paving materials with be used for
the site hardscape and high SRI roofing
materials for building waterproofing to minimize
heat island effect, both roof and non-roof. The
site lighting design will conform with IESNA
requirements to minimize nighttime light
pollution and trespass.
This building structure features concrete and
masonry walls and structural and structural
steel roof framing. The building walls and roofs
are fully insulated at the exterior perimeter;
all spaces, including unused attic area, are a
part of the insulated envelope and considerably
surpass the envelope requirements of ASHRAE 90.1
and the Energy Efficiency Requirements of the
Florida Building Code. Windows are double
glazed, argon filled and tinted. High
efficiency, two speed compressor units (roof
top) are utilized for all space cooling. Primary
water heating is from condenser unit heat
recovery with secondary electrical backup. A
rooftop photovoltaic array will provide up to
15% of the buildings electrical energy needs;
the building electrical service will include net
metering of excess power. Daylighting is
provided to 90% of the occupied spaces.
