"Our design mission was to aggressively address environmental and
sustainable attributes while creating practical facilities that would
complement each park's unique natural beauty," said Mike Corby, AIA,
LEED AP, who led Integrated Architecture's design of the project. The
state's initial proposal request mandated that the new facilities would:
1. Be environmentally responsible, meeting Michigan's green initiative
standards, utilizing sustainable, renewable energy as much as possible.
2. Create a positive experience that park clients would remember and
share with friends and family.
3. Blend with the surroundings and look like they belong in the park.
4. Respect the earth and fit into the landscape.
5. Utilize sustainable design to educate users about green facilities
and the environmental savings they offer.
Integrated Architecture's mechanical engineers studied options for
heating, ventilation, plumbing and electrical systems that ranged from
wood fired boilers to natural ventilation, waterless urinals and wind
turbine generated power. Each alternative included supportive
information and was either "recommended", "not recommended", or listed
as "possible". Architects and interior designers followed suit with
building materials and finishes.
The Phase 100 study included, but wasn't limited to, wind turbines,
geothermal heating, composting toilets, grey water reclamation, solar
photovoltaic panels and solar hot water heating. "We looked at many
different types of solar systems and finally chose a film photovoltaic
system, Silicon panel PV, to assist in powering the ventilation system.
We also created a building that maximizes natural light. Translucent
plastic panels in the upper third of the family shower rooms and
bathrooms bring light deep into the building," Randolph Pease, NCARB,
and member of the project design team stated.
Final recommendations included avoiding heating systems whenever
possible, and if required, limit them to a small portion of the building
using condensing boilers and in-floor radiant heat with a goal of
achieving 95% efficiency. Plumbing recommendations featured proven
commercial technologies such as low flow urinals, battery powered
electronic sensor faucets, 1.5 GPM showers and on-demand water heaters
rated above 90% efficiency, grouped together with one heater serving 3
showers. These suggestions were used to create standard specifications
and an adaptable, modular, prototype design that could be adjusted to
serve large and small parks.
"The design intent was to sandwich the shower and bathrooms between
three massive masonry walls that mimicked the nearby lake breakwater
walls. With the masonry walls taking the brunt of the wind and sand
energy, the infill would support light, minimal material that would then
define the shower and toilet rooms," Pease stated. "The pitch of the
roof and its Southwest orientation was perfect for the PV solar panels."
Besides the natural lighting and solar powered ventilation the facility
also offers energy efficient electric lighting with occupancy sensors,
timer-controlled showers, no/low VOC finishes, high recycled content
block walls, sinks, counter tops and toilet partitions. It's also
handicapped accessible and family friendly. The facility offers private
showers and shower/toilet rooms suitable for family or individual use.
The state's second green latrine is being designed for Otsego Lake State
Park, a 90-year-old state park with 60 large shaded campsites near
