We understand a building’s position within the greater context. We recognize its impact on its immediate surroundings and the environment as a whole, and we continually work to be responsible stewards of our neighborhoods and our planet. It is with this spirit that we approach projects with not merely an attitude of how we can create a minimal footprint, but rather how can we inspire and motivate behavior within and even beyond the structure.


Today, the building sector is the single largest consumer of energy and natural resources in our nation – a fact we simply cannot ignore.  At HKS, we understand that sustainable design can play a powerful role in conserving these resources while achieving energy independence, reducing greenhouse gas emissions, and effectively improving our client’s bottom line.

We believe the most successful, full-bodied design solutions are realized through an integrative process that encourages collaboration and the exchange of ideas.  At the heart of this process is the focus on synergies that exist between the building occupants, the natural systems, the design disciplines, the functions of the facility, and the economics of operations.  This cross-pollination of ideas leverages our collective knowledge and fosters a whole building design solution that performs better than the sum of the individual design strategies.


HKS DesignGreen is our consulting studio that assists and guides our design staff in implementing sustainable processes and strategies. From our growing knowledge pool, we apply best practices across projects and industries, and communicate daily with project teams in order to create maximum energy efficiency and a minimal lifetime footprint.

2030 Challenge

HKS committed to the Architecture 2030 Challenge because it understands the commitment and dedication required to produce iconic buildings that use less energy.  Architects have the social responsibility to determine and implement strategies into our designs to provide the opportunity and challenge to reduce global dependence on fossil fuels.  By reducing the energy use of HKS-designed buildings, the 2030 Challenge is playing a major role in reversing the negative impacts of global climate change.


Sustainability is more than just a word to us. Our commitment is documented and formalized as we continually strive to improve our operations and reduce our environmental footprint. The HKS Green Operations policy has been developed to formalize our goals and provide an operational framework for each of our offices worldwide.
