Energy is lost in two ways because of this. The first being the pressurized building forcing warm air out through any opening and the other being the constant introduction of cold air into the building. The air exchange system is provided with a day/night switch so it could be turned off and stop the fresh air intake. This would also shut down the air c~nditioning in the summertime. However, rather than assign an individual to this responsibility morning and evening for only five days a week or 70% of the time, I would recommend installing a timer on the system. The timer should be equippe~with a manual override so the system could be operated when the hours of occupation are extended (i.e. Council meetings). This would not only reduce heating costs, but would also lower cooling costs. Reduce Building Glazed Areas: The large glass areas at both the front and rear of the building are another area of substantial heat loss in the building. The radical solution to theis problem would be to dras- tically reduce these areas and install an insulated wall. Again, how- ever, this would destroy some of the aesthetics of the building° The alternate solution to this, while not as effective, would be to install some well-insulated draperies in these glazed areas. They could be opened or closed depending upon the results one would like to achieve (i.e. reduce heat loss, attain or reduce heat gain). This would also reduce heating costs and cooling costs. NOTE: Opening and closing of the existing blinds in the office areas would create similar savings.- Complete Entry Air Lock: In areas where doors are subject to continual opening to the exterior, air locks or a separate enclosure between the exterior and occupied heated areas of the building provide for energy conservation. The construction, as it exists at'.the main entrance, is only a draft stop and prevents the running of cold air across the floor. To con~ plete the draft stop to the ceiling and create an air lock would help. However, to be really effective, air locks should not be heated as this one would be. Outside construction of an unheated air lock may be a more practical solution to this particular problem. Reduce Water Heater Size/Water Temperature: The existing hot water heater would appear to be around two hundred gallons. This is about four times as much hot water as needed, as I'm sure our uses are less than the average residence. A reduction in the tank size and lowering of the hot water temperature would reduce energy consumption until such time as increased amounts of hot water are needed.
