In climate-responsive design the building becomes an intermediary in its own energy housekeeping, forming a link between the harvest of climate resources and low-energy provision of comfort. Essential here is the employment of climate-responsive building elements; structural and architectural elements in which the energy infrastructure is far-reaching integrated. Research is conducted on what knowledge is needed in the early stages of the design process and how to transfer and transform that knowledge to the field of the architect in order for them to successfully implement the principles of climate-responsive design. Content, form and functional requirements provide the framework for a design-decision support tool. A concept tool has been presented to architects in the field.
