The key to aesthetic, comfortable and energy-efficient buildings is found in the interaction between architecture and technology. At Henning Larsen Architects, we have made the concept of sustainability tangible by focusing on the reduction of energy use as our primary strategy. We have done this with the belief that focusing on energy can create comprehensive quality in every aspect of a project. This is based on the methodology of our book “Design with Knowledge,” which was published in 2012. Specific focus areas have been developed with the fundamental objective of creating value at three levels of sustainability—the economic, social and environmental.
