Occupant thermal comfort was evaluated through questionnaires and concurrent measurement of workstation comfort parameters. The radiant system energy performance was found to be poorer mainly due to: (1) simultaneous cooling by the slab and heating by other systems, (2) omission of low-exergy (e.g., groundwater) cooling possible with the high cooling water temperatures possible with radiant slabs and (3) excessive solar gain and conductive heat loss due to the wall and fenestration design. Simulation was then used to compare the radiant slab design with a conventional (variable air volume) system. Accuracy of a whole building energy simulation model was evaluated with these data.

Measurements included: (1) heating and cooling energy use, (2) electrical energy use for lighting and equipment, and (3) indoor temperatures. Thermal comfort and energy performance were evaluated. The University of Calgary's Information and Communications Technology (ICT) Building, is a pioneering radiant slab cooling installation in North America. There is little field evidence to test these claims. Some argue that radiant cooling simultaneously improves building efficiency and occupant thermal comfort, and that current thermal comfort models fail to reflect occupant experience with radiant thermal control systems. Negative environmental impacts include CO2 emissions from electric generation and leakage of ozone-depleting refrigerants. Core regions of large buildings require year-round cooling due to heat gains from people, lights and equipment.

In another embodiment, the radiant energy device may include two interconnected hyperbolically shaped reflective elements with a respective convex lens being provided at each aperture of the device.ĭesign of energy efficient building with radiant slab coolingĪir-conditioning comprises a substantial fraction of commercial building energy use because of compressor-driven refrigeration and fan-driven air circulation.

Due to the provision of the lenses and the shape of the walls of the reflective element, the radiant energy incident at the radiant energy inlet within a predetermined angle of acceptance is emitted from the radiant energy outlet exclusively within an acute exit angle. A convex lens is provided at the radiant energy inlet and a concave lens is provided at the radiant energy outlet. A nonimaging radiant energy device may include a hyperbolically shaped reflective element with a radiant energy inlet and a radiant energy outlet.
