Energy Integrated Design of Lighting, Heating, and Cooling Systems and Its Effect on Building Energy Requirements

The continuous control of interior environment with today´s requirements for higher lighting levels has greatly altered the way in which energy is consumed in buildings. In order to optimize the energy input and achieve environmental control, we must utilize the systems approach. The lighting, heating, and cooling systems must be interrelated so that we can utilize available internal energy to satisfy the heating requirements and simultaneously reduce the energy input by eliminating the refrigeration and air handling associated with collecting lighting and solar radiant heat.
