The McKinney Green Building, designed by HDR Architecture, Inc., recently joined the ranks of elite buildings to earn a coveted LEED Core & Shell (CS) Platinum Rating from the U.S. Green Building Council.

The 61,000-square-foot speculative office building features a number of innovative and significant sustainable design elements that contributed to it being awarded the highest rating possible for a high-performance building. "This project is tangible proof of how successful an integrated design process can be when owner, designer, commissioning agent and contractor partner together in developing cutting-edge solutions for otherwise traditional projects," said HDR architect and McKinney project manager Curt Parde, LEED AP.

The three-story office building in McKinney, Texas, was designed by HDR Architecture for West World Management, Inc. The owner challenged HDR to think and design creatively in order to meet a number of sustainable design goals within the confines of a tight construction budget. In the end, the team was not only able to meet the owner's original goals, but exceed quite a few of them as well. "Everyone involved in the McKinney Green Building project became both increasingly aware of the potential for sustainability throughout the process, as well as the many shortcomings of conventional building industry practices," noted Parde. "New methods were identified to redefine routine design and construction practices to achieve the most positive impacts on our industry and the planet."
Key sustainable design features of the McKinney Green Building include:
• 62 percent reduction in energy use (versus a building that meets basic ASHRAE 90.1 standards) due to an energy-efficient building envelope, use of sunshade devices, an underfloor air distribution system, efficient fenestration and high insulation R-value for roof and walls.
• Rooftop photovoltaic system that supplies approximately 10 percent of the building’s electric demand, and designed to accommodate future expansion.
• A two-year contract with a Texas wind energy provider.
• Use of occupancy and daylight sensors for lighting control and energy savings.
• Open plan design that maximizes daylight filtration and views to the outdoors.
• High daylight glazing that allows sunlight to penetrate into the building, while exterior sunshades bounce daylight deep into the building core.
• Reduced water usage due to waterless urinals, and low-flow toilets and faucets.
• Reduction in site irrigation requirements because of drought-tolerant landscaping.
• Designated HOV parking spaces, plug-in stations for alternative fuel vehicles and bicycle racks/shower facilities.
• Underground stormwater storage system for rainwater harvesting.
• Low- or no-VOC paints, adhesives and sealants.
• Formaldehyde-free wood panels and FSC-certified wood products.
• 46 percent of materials manufactured regionally, and 11 percent with post-consumer and post-industrial content.
• Stone, brick and stucco finishes that require minimal maintenance and provide maximum durability.

The high-performance building has also received the Texas Renewable Energy Association's 2006 Building of the Year, and a Top 10 Award from the Dallas/Fort Worth Topping Out 2007.

The McKinney Green Building is HDR Architecture’s second Platinum-rated building. In 2006, the Banner Bank Building in Boise, Idaho, was also awarded a LEED CS Platinum Rating. These two buildings represent just a portion of the over 7.2 million square feet of LEED-certified and -registered buildings designed by HDR, which makes the firm one of the top design firms providing LEED services to clients.
