THAT Report No. ECC -01-86 be received for information. BACKGROUND AND COMMENTS: The energy program is continuing with diagnostic audits on facilities owned by the Municipality. A grant application is being submitted to the Ministry of Energy for an energy related project recently completed (ie. window retrofit at the Newcastle Fire Hall). This report specifically deals with energy conservation alternatives that were considered as well as those that are recommended for several of the facilities owned by the Town of Newcastle. Respectfully submitted, Kevin Greene, Energy Auditor Corp. of the Town of Newcastle KG*sa NEWCASTLE FITNESS CENTRE Findings and Recommendations From the preliminary assessment of the facility ,several energy conservation alternatives were considered; 1. Fool Cover 2. Whirlpool Blanket 3. Ceiling Fans to destratify air 4. Run Around Heat Recovery System 5. Dry -0- Tron Dehumidification System 6. Disconnect Ballasts 7. Occupancy Detectors The pool cover alternative was refected first for the following reasons. The pool has a high activity schedule. There is limited deco: space available for storage of the blanket. Also, pool covers add another potentially dangerous safety hazard to the system. A whirlpool blanket while still restricted by the length of time it can be used is easily stored and is much less of a safety hazard. Ceiling fans that destratify air in a pool have been found to increase forced convection over the pool surface and actually increase evaporation and energy costs. Ceiling fans are not recommended. The first heat recovery system investigated is the Run Around System. Glycol is circulated through finned tube coils located in the exhaust and supply air streams. Up to 60% of sensible heat is recovered. The second heat recovery system is the Dry -0- Tron Dehumidifier that absorbs latent as well as sensible heat. The overall expected efficiency can reach 90%. From a theoretical point of view the Dry -0- Tron System is sound. It is recommended that the Dry -o- Tran be installed. Half of the Flourescent light fixtures in the multi purpose room have had their bulbs removed. This practice has saved energy yet one further step should be taken. While the bank of fixtures is switched on, all of the ballasts are energized regardless of whether the bulbs are present or not. It is recommended that the ballasts from the unused fixtures be disconnected in order to optimize savings. Occupancy Detectors in the squash courts will be recommended pending price quotations. The Detectors' function will be to reduce electrical consumption by monitoring court usage and controlling lighting load. DARLINGTON SPORTS CENTRE Findings and Recommendations The following energy conservation alternatives were considered for this facility; 1. Egosaver 2. Compressor Staging 3. IFC Fuel Saver 4. Brine Pump Actuator The Egosaver is a heat exchange system that removes the superheat that is rejected from the compressor. The heat removed would be injected into a water storage tank: that supplies water for showers and ice flooding. Compressor Staging is a control method that allows one compressor to be on line during reduced load periods. At present both compressors start up regardless of cooling load, then both shut off simultaneously. This on-off cycling increases the demand charge that the facility is penalized for by Ontario -Hydro. The Fuel Saver is a forced air furnace control. It effecitvely converts the conventional furnace to a pulse system. By "pulsing" the burner, less flue gas is created and the lower heat exchanger temperature results in a longer furnace life. This unit comes with a 20% fuel saving guarentee. Since compressors operate approximately 55% of the time during the ice season, the brine pump need only operate for approximately the same period. An ire temperature sensor will control the cycle period. Price quotations on this product have not been received as vet. BOWMANVILLE WORKS BUILDING HAMPTON WORKS BUILDING ORONO WORKS BUILDING Findings and Recommendations The following energy saving alternatives were considered for these facilities; 1. Install Storm Windows 2. Setback: Thermostat _. IFC Fuel Saver 4. Caulking & Weatherstripping S. Increase Wall Insulation Increase the "R" Value of the single pane window units by installing storm windows. The setback thermostat will automatically reduce the building temperature during unoccupied periods. These units though computer controlled and programmed have manual overides. At present a. constant "daytime" temperature is maintained twenty-four hours a day. The IFC Fuel Saver as previously mentioned converts conventional on-off furnaces to a pulse style. Caulking and weatherstripping are required to reduce the high infiltration and exfiltration rate that exists at this facility. Increasing the thermal resistance of bloc: walls is usually advantageous. Howerver this can not be recommended until price quotes have been received. NEWCASTLE FIRE HALL Findings and Recommendations The following energy saving alternatives were considered for this facility; 1. Insulate One Garage Door . Bloch: and Insulate One Access Door 3. Storm Windows 4. Caulking & Weatherstripping The smaller north facing garage door should be insulated. A prefabricated insulation k:it is recommended. The north facing door that enters the office area should be blocked off and insulated. This door is not presently being used and therefore the lower "R" Value associated with these doors can be increased. Storm windows have been installed over single pane windows in order to increase thermal resistance. Caulking and weatherstripping of the bay doors will greatly reduce infiltration and exfiltration. COURTICE FIFE HALL Findings and Recommendations These energy saving alternatives were considered for this facility; 1. Wall and Ceiling Insulation 2 3. Increase the "R" Value of the building envelope in order to reduce the energy consumption of the heating plant. Price quotations will ultimately determine its worth. ORONO FIRE I4ALL Findings and Recommendations These energy saving alternatives were considered for this facility; 1. Lower Ceiling Level 2. 71. Since the Orono Fire Hall is a new structure and proper insulation and windows are in place, there will be no recommendation to improve the "R" Value of this facility. However, the bay area ceiling is much higher than necessary. By lowering the ceiling height, convection currents and destratification are reduced. fp VISUAL ARTS CENTRE Preliminary Findings and Recommendations * These energy saving alternatives were considered for this facility; 1. Reinstall Insulation - 2. Install Vapour Barrier ... "Tighten building Envelope In order to obtain use of your upper floor the batt insulation that is now on the floor must be put between the rafters. The insulation as it sits on the floor is relatively useless since there is no appreciable vapour or air barrier. After moving the insulation, cover it with a continuous 6 mil. polyethelene sheet. Cracks in the building structure must be filled and install tight fitting double glazed windows to replace the plywood. BOWMANYILLE LIBRARY * Preliminary Findings and Recommendations * These energy saving alternatives were considered for this facility; 1. Reflective Window Film The building structure is predominantly glass. A method of improving this conductive material was sought. Reflective window film is a good choice due to it's low emissivity characteristics. The film will radiate heat back into the building effectively reducing the heating plant load in winter. In the summer the suns heat will be reflected outward making conditions more comfortable. CLARK: PUBLIC LIBRARY * Preliminary Finding and Recommendations * These energy saving alternatives were considered for this facility; 1. Storm Windows �. Caulking and Weatherstripping At present the Upper floor windows are sinle pane glass. The windows should be supplimented with exterior storm sashes. Weatherstripping and caulk:i.ng are required throughout the building in order to "tighten" the building envelope. BOWMANVILLE ARENA Findings and Recommendations This energy saving alternative was considered for this facility; 1. Change Lighting At present the ice rink: is illuminated with 7.6 incandescent bulbs (the least efficient form of lighting). By installing metal halide high intensity discharge lamps, significant savings can be made. It is recommended that this improved form of lighting be installed if the arena will be kept operational for at least one more ice season. At the time when a new Howmanville Arena is built, these new luminaires can be transferred from Memorial Arena to the new building.
