104. rising result this table reveals is that the retrofitted Domes together used significantly more energy than the baseline Domes This is somewhat alarming however it can be explained by a careful examination of the monitored performance data One of the major contributors to the retrofitted Dome energy use is cooling energy Because the baseline Domes do not have any mechanical cooling it is expected that the retrofitted Domes would use more HVAC energy during the summer However as the following figure illustrates the retrofitted Domes do generally stay cooler inside and peak temperatures were lower During this period the baseline Domes reach indoor temperatures well over 90 degrees F which is of course outside the generally accepted comfort ranges So while mechanical cooling does increase energy use it is justifiable as it provides a more comfortable and reasonable living space 20 Pacific Gas and Electric Company PG amp E s Emerging Technologies Program 2 6 1442 Average Dome Temperature 100 70 4 Average Retrofit Dome Temperature F 65 Average Baseline Dome Temperature F 60 55 4 o N lt aja 5 3 5 S 3 S S 5 S S R 5 8 8 6 a A E a Q g amp E 5 LM N M M N o gt gt gt gt FIGURE 13 AVERAGE INDOOR TEMPERATURES A second important observation is that the domest
