 ENERGY CONSERVATION TECHNIQUES
1. Outside ventilation air intake in unoccupied buildings should be closed to
achieve rapid acceleration to proper temperature (air conditioning or
heating), e.g., to bring air conditioned building down to temperature in the
morning (0600 to 0730 hours) before workers arrive.
2. To provide the greatest resistance to heat flow downward, use aluminum
foil backed insulation, or aluminum foil backed gypsum board facing upward or
outward and facing a closed air space.
3. Use double effect absorption refrigeration machines instead of single
effect.
4. Use total energy (TE) systems whereby electric power is generated by a
diesel engine or combustion turbine and all heat from the oil cooler, engine
jacket (ebullient cooling) and exhaust gases (waste heat boiler) is used for
domestic hot water, space heating and air conditioning (absorption
refrigeration).
5. For calculating air conditioning cooling loads for personnel comfort only,
eliminate practice of adding safety factors for sensible, latent and total
cooling loads.
6. Select air-cooled condensers based on a maximum differential between air
entering and condensing temperature of 25 degrees F.
7. A life cycle cost comparison study shall be made to determine whether
electricity, fuel oil or gas is to be used for domestic water heating. Note
that the maximum thermal efficiency of central power plants is 30-40 percent
whereas the efficiency of direct-lined fuel burning equipment varies between
60-80 percent.
