The Clinton Library was designed with green and sustainable design features such as bicycle racks and shower/changing facilities for employees who commute to work, in-floor radiant heating and cooling systems, landscape & exterior design to reduce heat islands, soil erosion and sediment control during construction, energy performance optimization, photovoltaic panels as a renewable energy source, additional building commissioning measures, advanced control systems for measurement and verification of energy consumption, use of recycled content materials, use of locally/regionally manufactured materials, an American Hydro-Tech Roofing System, and use of low-emitting materials, just to list a few examples.

The Heifer lnternational Center used many of the same features mentioned above as well as several others, such as under-floor air distribution, waterless urinals and a gray water vessel, which recycles rainwater for use in landscaping irrigation and flushing toilets in the building. The southern elevation of the building features vertical and horizontal 'fins' and light shelves, which block direct sunlight from employees in the building while allowing natural light to 'bounce' off the light shelves and into the middle of the building, maximizing the use of natural light and lowering energy usage. In addition, constructed wetlands and bioswales channel rainwater within the site and minimize storm water runoff. Pervious paving was also utilized to assist in storm water retention and reduce heat island effect.

On the Heifer lnternational Project, CDI Contractors utilized construction waste management throughout the project to divert as much construction and demolition debris as possible from landfill, with a goal of diverting 75% of all debris generated during the project. The site contained over a dozen existing buildings and concrete slabs, and a concrete paved parking lot. By thinking "outside the box", we were able to recycle or salvage 97% of all debris generated during demolition. By utilizing a concrete crusher like those seen on highway projects, we were able to generate over 15,000 tons of highway spec gravel to be used during construction of the building for backfill and foundations, and saved the Owner over $100,000 in the process.

The under-floor air distribution will serve a number of beneficial purposes for the building, such as employee control over their personal workspace by utilizing manually operated dampers in the raised floor panels. Moreover under-floor air distribution requires less ductwork than conventional HVAC systems, reduces static pressure, and allows smaller HVAC equipment, which costs less and uses less energy. The Heifer lnternational Center consumes 50% less energy than a typical office building of the same size.

The Frisco Conference Center in Frisco, Texas includes green and sustainable design features such as bicycle racks and a shower/changing facility for employees who commute to work, soil erosion and sediment control during construction, utilizing an indoor air quality plan to protect the indoor environment from contamination during construction, additional building commissioning measures, advanced control systems for measurement and verification of energy consumption, high efficiency mechanical equipment, using recycled content materials, recycling material waste on site, using locally/regionally manufactured materials, low-emitting materials, and gray water for landscaping irrigation.
