A client was pleased with the performance of a recent building designed and built with low energy objectives on the "mixed mode" principle. When the time came to build another building he appointed the same design and construction team and challenged them to suggest cost effective improvements to the environmental features of the original building. The team developed a "shopping list" of potential energy use reducing features that included chilled slabs, which could be cooled by both a cooling pond and mechanical refrigeration. Fortuitously the site had sufficient space for a cooling pond. This paper is a case study of the design and installation and, commissioning of the building cooled by chilled slabs operating alternately on passive (natural ventilation/cooling pond) and mechanical (refrigeration) cooling.
