Deru, M; Benne, K

Synergistic systems are: (1) Dedicated Outdoor Air System (DOAS) - Efficient ventilation and dehumidification, Works well with energy recovery, Potential to cascade chilled water to radiant system; (2) Radiant heating and cooling - Comfort heating and cooling, Efficient delivery of energy, Improved zoning capabilities; and (3) Tighter envelope - Reduce uncontrolled loads, Humidity and Cold air. Whole building energy analysis of retrofit energy conservation measures. Conclusions are that: (1) These are preliminary results - further analysis for actual projects should completed; Savings depends on the starting point; Higher savings in the barracks because of 24 hour occupation vs. half-time occupation in the office; and May be difficult to justify retrofit just for energy savings; however, the premium cost over a standard retrofit can be cost effective.
