The Bannister Federal Building has long provided warehouse space for government services. BNIM’s adaptive reuse of a portion of this space from warehouse into office space incorporates a skylight atrium and circulation corridor, which provides light to a shared conferencing center and the offices of the Federal Supply Service. The FSS reports that employees from other parts of the building are seeking out the amenity of the atrium and its own employees have increased capacity.

The building was designed to save 33% more than a similar ASHRAE 90.1 1999 compliant building.
The building was designed to easily install photovoltaics on the roof structure for further emission reductions and self-reliance.
Daylight penetration was a key strategy so that all occupants have access to natural light. Vertical atria and a horizontal atrium provide additional controlled daylight.
Operable windows are installed throughout the building and could be open approximately 134 days or over 1/3 of the year.
Indoor air quality has been improved with healthy interior materials such as agri-fiber board and low VOC paints, adhesives and sealants.
For teaching and offices spaces, an under-floor air distribution system is used to increase energy efficiency and provide increased thermal comfort for building users by providing user controls.
Flexible building elements such as raised floor and demountable partitions will accommodate building changes over time.
Efficient plumbing fixtures such as waterless urinals, low flow lavatories and low flow showerheads are installed throughout.
Rainwater storage tanks capture approximately 826,140 gallons of rainwater or “grey” water (non-potable water) per year fulfilling the estimated 42,000 gallons needed each month for toilet flushing and irrigation
Water reduction strategies amount to a 93% total reduction of potable water through the reuse of collected rainwater for flushing and irrigation, as compared to a LEED baseline case.
75% of the building’s total construction waste was recycled or salvaged—including waste from the deconstruction of the building that had previously occupied the site.
Building materials were chosen to minimize environmental impact and include recycled brick from a 19th century warehouse in Texas, wood siding from reclaimed cypress logs, aluminum panels specially fabricated with 92% recycled material, and structural steel specified to have more than 80% recycled content.

In 2007, Greensburg’s City Council became the first city in the country to adopt a resolution that all city projects would be built to LEED Platinum standards and would exceed the baseline code for energy efficiency by 42% The community also set a progressive goal to be powered by 100% renewable energy generation. As of 2010, a city-owned wind farm, which is a net exporter of renewable energy, is meeting that goal.

38% Annual Energy Savings due to KCP&L's Energy Reduction Strategies
BNIM’s design for the LEED Gold KCP&L Headquarters demonstrates the ability to introduce high performance, integrated design into an existing office tower. The move into 230,000 square feet of existing downtown office space serves as a powerful example to other building and business owners. The design decisions made at KCP&L will also make the space more cost effective to operate. The strategies focus heavily on optimal HVAC and workstation configuration.

Summary of energy and carbon reduction strategies:
An under-floor air distribution (displacement air) system improves thermal comfort because the supply air is delivered at a more comfortable temperature (64 degrees vs. 55 degrees when cooling is required for instance) and at a lower velocity. Thermal mass from cast-in-place concrete structure and exposed interior wythe of insulated precast concrete walls helps to even out temperature fluctuations within the building.
Insulated precast concrete walls with unique terra cotta exterior skin provide U-0.048 for approximately 53% of the overall wall area.
A high performance curtain wall system uses “Low E” double pane insulated glass with argon gas ( U-0.36, SHGC - 0.30) for 47% of exterior wall area.
Materials: use of recycled materials in as many products as possible such as recycled glass countertops fabricated from recycled glass collected locally; all wood is FSC certified; limestone reclaimed from site retaining walls repurposed for use as limestone seating benches around the exterior of the building
The building uses a white TPO roof with a vegetated green roof on Level 4. This “cool roof” reflects significantly more sunlight and absorbs less heat than traditional dark-colored roofs, resulting in reduced building heat-gain, energy savings during times of the year that require air-conditioning, and extended service life of the roof.
Skylights and ample glazing to provide daylight to the building along with daylight sensors and controls to limit the need for lights during daylight hours
Efficient plumbing fixtures save 42.14% compared to the LEED 2009 baseline
Monitoring capabilities were added to mechanical systems to allow the measurement of energy usage for life of building:
82.9 kBtu/SF/year predicted EUI excluding on-site renewable energy contribution
o 36% regional reduction per Energy Star Target Finder compared to ASHRAE 90.1, 2007 (60% reduction compared to Architecture 2030 Challenge Interim Code Equivalents)
The site design incorporates subtle strategies to treat stormwater without creating large rain basins that would distract from the formal design aesthetic. Rain basins are incorporated throughout the groundcover and planting beds to clean runoff and direct it to storage zones underneath the project parking lots. In addition to the aesthetic benefits the green roof provides to the upper floor offices and outdoor terrace, it also helps to reduce the stormwater volume leaving the roof.

27% Reduction in Crime
Bancroft school signals a catalytic shift in community revitalization, that began with the residents of Manheim Park boldly claiming a new future, and a broad public-private partnership and strategic investment of leadership, design, capital and philanthropy. This effort has already resulted in a remarkable reduction in crime — from 2011-2012 there was a 27% reduction in crime reported — and increase in hope. As residents claim their new homes, the legacy becomes the development of human capital by design. This is urban acupuncture, and it redefines urban redevelopment.

The strategies employed by the project team—a true collaboration across multiple disciplines—and a complete MEP systems reconsideration deliver significant energy savings in comparison to the building’s prior consumption. Before the renovation, the AEG building was consuming 171 kBtu/sf/year and had two thermostats controlling the entire system. Following the renovation, the project is modeled to operate on 59.2 kBtu/sf/year, representing a 65% energy savings. Almost 230 thermostats now control the building’s systems, giving each quadrant on each floor the ability to change temperatures. The renovation and repair will save the company up to $2 million a year in energy and repair costs.
The specification and installation of healthy material choices throughout the interiors also supports the larger, human-centered strategy that was the heart of the restoration effort. More than 50% of all wood in the building is Forestry Stewardship Council (FSC) certified wood, 20% of all material installations were comprised of recycled content, and 89% of construction waste was diverted from the landfill.
