RJC Engineering LLC was founded by Ray J. Clark a retired partner of Skidmore, Owings & Merrill LLP. In his 30-year career at SOM he directed the engineering design of numerous tall buildings and large-scale international projects in over 35 countries including the world's tallest building, Burj Khalifa in the UAE, the Jin Mao Tower in Shanghai, PRC and the Korea World Trade Center in Seoul, South Korea.
His focus throughout his career has been on integrated solutions of architecture and engineering with a particular emphasis on energy efficiency and sustainable design. He published his first paper on the topic in 1975 entitled "Finding the Best Angle and Spacing for Solar Collectors". A few years later, with SOM, he performed the thermal modeling on the Haj Tents at the King Abdul Aziz International Airport. This was one of the first sustainable projects worldwide and in 2010 received the prestigious AIA Twenty-Five Year award. The project incorporated 260,000square meters of fabric tent structures to temper the environment below. In the following years, he has over 30 projects that received ASHRAE awards for Energy Efficiency and Excellence in Engineering.
