This 160,000 square foot, 19.5 M, substantial renovation project, was
a collaborative effort from the start, with the areas of work including
the high school, convent, chapel, and courtyard. Sota Construction Services
Inc. was chosen as the general contractor, with the Sisters included in
every step of the decision making process.
The architectural plans, three years in the making, alllowed for new,
accessible, residence rooms, and a new school layout. The redesigned courtyard
spaces provide an appealing area for students and also allow the Sisters
much needed direct access from the building.
The coordination of the new mechanical and electrical systems with the
existing window heights and building structure was a challenge that was
met. The new systems were routed to preserve the original ceiling heights
and to maximize daylight penetration.
The project is a LEED registered project with a gold rating target. Green construction elements included significant reuse of existing materials, specification of recycled content materials, recycling
of on-site construction waste. and specification of sustainable furniture.
Besides the reuse of over 300 doors and transoms, miles of wood trim and
1 acre of wood flooring, all of the new partitions were built using recycled
metal studs, recycled drywall made from fly-ash and recycled mineral wool
sound insulation.
Extensive interviews with the Sisters regarding the occupancy schedule
of the various spaces allowed the HVAC system to be reduced by 45 tons.
High efficiency water source heat pumps were used with energy recovery
units on the roof to provide fresh air and recover energy from the exhausted
air. The building exceeds ASHRAE 90.1 for energy efficiency by 35% providing
significant long term savings and environmental benefits. DOE 2 modeling
of various alternatives was used to evaluate thermal improvements. The
over 900 windows in the building are used to maximize natural lighting of the spaces. White
reflective TPO roofing was used to minimize heat island effect and to
reduce load. A direct digital control system will provide setback and
monitoring of the hvac units.Waste heat from kitchen refrigeration will
be input into the heat pump water loop. Photocells in the classrooms will
turn off lights when natural light is present.
But most important, the Sisters have stated their satisfaction with the
project and in fact have reported better health on the part of those suffering
respiratory ailments.
