Two new projects certified LEED Platinum in 2011 Wellmark Blue Cross Blue Shield, Des Moines, Iowa
HOK Bryant Park, New York, NY
LEED NC Platinum | HOK Chicago
LEED CI Platinum | HOK New York
Wellmark is the world’s largest LEED Platinum single-user, owner-occupied corporate office building. An elliptical entry garden and pedestrian walkway area is carved deep into the building’s facade to allow maximum penetration of daylight into the core.
A showcase in integrating BIM and sustainablity in the design process, the New York office incorporates numerous advanced building technologies to optimize daylight and minimize energy costs with a predicted reduction of CO2 emissions by 55 tons annually.

The Wellmark Headquaters has been designed to incorporate sufficient daylight and views into the completed spaces. This design criteria has been established to increase the productivity and health of all employees while decreasing enery demand for artificial lighting within the building. The daylight analysis for the building was complete with Ecotect and Radiance software. The reports were formatted to indicate LEED NC v. 2.2 requirements for daylighting. Daylight levels were calculated for all regularly occupied spaces at 30” AFF. All results were calculated for the equinox (March / September 21st) at noon. LEED requires that 75% percent of spaces meet the indicated illuminance levels. The results to the left incorporated window aperture, glazing with a visual transmittance of 0.5, sun shading devices, interior partitions, ceiling soffits and representative surface reflectance settings for interior finishes. 42” and 54” inch work station partitions were used for this analysis. The calculation indicates that 76.8 % of the Wellmark regularly occupied areas Predicted Total Energy Use: are compliant with LEED daylight requirements. This is LEED compliant.

Back to cover PRACTICES: Embody Exemplary Green Operations
People Roadmap Operations Plan Roadmap Measure:Measure 2011 Innovative green operations ideas Most offices have incorporated local innovations to help drive their sustainability message. Here are two 2011 examples:
COMPOSTING - St. Louis Office
100% REPURPOSING - Hong Kong Office
At HOK’s urging, the Metropolitan Square building manager initiated a building-wide compost pilot program adopted by eight tenants and based on the model HOK St. Louis created for its own office. The HOK in-house compost campaign begun in Fall 2011 has already resulted in significant diversion from landfill. This is the first program of its kind in the city of St. Louis.
In its 2011 move, the Hong Kong office was able to repurpose all of its existing furniture to local organizations and schools. In the demolition of the new space, all glass, wood, wood doors, and boxlight fixtures were donated to local recycling and salvage organizations.
