Specifying Blended Cements for Sustainable Healthcare Design Cementitious-based building materials and LEED by Andrew Pinneke, PE, LEED AP Photo courtesy Donley’s Inc. HOSPITALS, CLINICS, AND OTHER TYPES OF MEDICAL FACILITIES ARE STRIVING TO CREATE HIGH- PERFORMANCE BUILDINGS MORE CONDUCIVE TO HEALING, WHILE ALSO REDUCING ENERGY AND WATER CONSUMPTION TO MINIMIZE THEIR ENVIRONMENTAL FOOTPRINT. As the demand for sustainable design and building practices grows, concrete and cementitious-based building materials are making a strong contribution to the construction of new healthcare facilities. Concrete and blended cements can be used to achieve credits under the U.S. Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) program in uses ranging from stormwater management to the improvement of indoor air quality (IAQ). They do so while also offering possibilities for versatile design innovations using shape, color, and texture. With the longest life span of any building material, concrete has all the advantages to respond to the challenges of sustainable healthcare construction. A mixture of natural substances, concrete is locally produced, 40 the construction specifier | april 2013 CS_April2013.indd 40 3/14/13 11:49:01 AM
