Thinking creatively to address environmental challenges and discover efficiencies for office building development within a harsh climate.

Energy Modeling
Kuwait Gulf Oil Company

Kuwait Gulf Oil Company (KGOC) commissioned Wight & Company to provide Energy Modeling and Sustainability Consulting services for a new 850,000 sf office building designed by a local Kuwaiti firm. We assisted with the design of the building envelope, allowing a window-to-wall ratio that would deliver comfort, daylight and energy savings to KGOC and its employees. Our sustainable strategies also included the use of electrochromic glass and 11 five-story “Living Wall” biofilters integrated into the mechanical system to filter return air. These energy conservation measures, when combined with on-site renewable energy, resulted in a 34% predicted energy use reduction over the baseline. The project earned 58 points in its LEED design phase, just two points shy of its ultimate target, LEED Gold.

Climate Challenges

Thinking “green” in an arid desert climate presented new and exciting challenges for our sustainability specialists. With temperatures exceeding 115 degrees Fahrenheit during summer months, sunlight had to be controlled. Through the use of electrochromic glass, visible light transmittance and the shading coefficient can be increased or reduced based on the time of year and time of day to control glare and limit solar gain. This increases comfort and reduces energy use.

Kuwait also faces massive sand storms, presenting a challenge when we considered air circulation in the building. Our solution was to recommend the installation of  of biofilters, or “Living Walls”, that save energy, recirculate air, and reduce dust. These biofilters are integrated into the mechanical system to filter CO2, rather than reintroduce outside air. The roots in the plant systems are grown in mats and cleanse the air naturally. The result from using this technology is a healthier indoor environment and lower energy use.
