Last Wednesday’s (9.24.08) presentation at Sustainable Springfield’s monthly meeting featured a power point along with material samples for Erin’s Pavilion, now under construction. The site is the new Southwind Park located on South Second Street, just south of I-72, and is being built and maintained by the Springfield Park District.
David McDow, an architect from Walton & Associates aptly presented the features of the building’s design in terms of how it will be designated as a US Green Building Council’s LEED (Leadreship Energy and Enivironment Design) rating of platinum, the highest designation that can be achieved.
The project is a 15,000 sq ft structure designed to employ “universal design” which means that the building is completely handicapped accessible. The projected cost of the building is $4 million and is the first of several structures to be built. Its completition date is July 2009.
Also planned for the park are a new Boys and Girls Club, for which a Federal Grant of $800,000 has been pledged for the project. Another project proposed is the “Kidzeum” children’s museum for which $1.25 million has been pledged by St. John’s Hospital.
The Park District has applied for and received grants from the Illinois Clean Energy Community Foundation. One for photvoltaic solar panels, $135,000 and another for an electrical generating wind turbine $150,500. Both installations will be sited in other areas in the park.
Erin’s Pavilion construction eco-friendly design includes several sustainable and energy savings features, which when taken in total will earn the LEED platinum rating:
- Recycled gypsum wall board for interior partition construction
- Recycled plastic used for toilet partitions
- Agri-fiber (wheat stalks etc.) manufactured doors
- Recycled cardboard “Paper Stone” manufactured counter tops
- Light weight fiber & concrete panels “Tectum” roof/ceiling structure
- T5 & T8 energy savings fluorescent lighting
- Occupancy sensors to regulate lighting & heating/cooling systems
- Geothermal heat exchange to cool the building in the summer & heat during colder months with heat sink in the park’s lake.
- light colored TPO, thermal plastic overlay roofing better to reflect the sun’s heat
- Linoleum flooring in lieu of vinyl
- Cork wall coverings
- Use of low VOC (volitale organic compounds) for paints and adhesives
- The use of Insulated Concrete Forms (ICF) utilized for exterior wall construction.
- These forms have rigid insulation on both the inner and outer surfaces with metal bracket separation that hold steel reinforcing. This construction provides an R22 wall as opposed to a R7.6 required by code. Thes form are constructed in sections much like logo blocks.
The projecten energy savings for this building per year are estimated to be below $1.00/square foot at $.39/square foot. The standard estimate for standard non sustainably built buildings is $4.00/ square foot.
LEED Building Costs vs Standard Construction Costs & Project Team Approach
When asked about the cost difference between a LEED building construction vs a non-LEED constructed building, Don Walton the firm’s principal said that there was little cost difference. Given that this structure was planned as a high quality structure, the cost difference is minimal. With a lower standard of construction, however the cost of a LEED building would be greater.
Mr. McDow emphasised that it was very important that a team be assembled that is dedicated to the LEED system beginning first with the building owner. The architect’s brought together a consultant group team of specialized firms including Vertigy, a St. Louis based LEED consultant.
