Any building must use combined-cooling-heating-electricity generating units to be considered “CLEAN” or “GREEN”. Sodium Sulphur batteries or Vanadium redox batteries to shift the electrical load to off peak and to store electricity from the CHP unit are also important. Large tanks to store hot water as well as ice storage for cooling peaks are also important. It is also time to consider Direct Current wiring to save on electrical losses. The power buses can be fed directly from the batteries. All lighting fixtures, including fluorescent, can now be fed with direct current which eliminates some loses in conduits. All motor drives can also be fed with direct current with increases in reliability and efficiency. The drives which match the motor speed to energy needs already are reducing power losses, but their performance and reliability would be increase with the use of direct current input. Where alternating current is needed for standard equipment, high efficiency pure sinewave inverters can be employed, and their cost can be quite low with high efficiency. ..HG..

When you say that “the building’s conventional light bulbs and tubes will be replaced with energy-efficient ones”, does that mean LED lights, or just fluorescents?
