Operations & Maintenance: Miscellaneous
- Calibrate checkmeters. Checkmeters should be reviewed every few years to ensure accuracy. The accuracy can be checked by comparing the consumption from the master meter with the consumption from all of the checkmeters. If they are not the same, then the checkmeters should be re-calibrated (adjusted for accuracy).
- Check for and repair water leaks. Staff should check the distribution lines on the street and the service lines on the property. The valve between the distribution line and the sewer line should also be checked. Residents should be encouraged to report water leaks on faucets, showers, tubs, toilets, or garden hoses. Any water leaks inside or outside the buildings should repaired immediately.
- Reduce ventilation rates. Outside air used for ventilation must be heated in the winter, and, in buildings with air conditioning, cooled in the summer. When the amount of outside air taken into a building exceeds the amount required by code, ventilation rates can be reduced to save energy.
- Reduce the amount of exhausted air. In buildings with an air exhaust system, air that is exhausted must be replaced by the air intake system or by air infiltrating into the building. Incoming air must be heated in the winter, and, in buildings with air conditioning, cooled in the summer. Reducing the amount of exhausted air can save energy by reducing the need to heat or cool this air. The exhaust system should be operated only for short periods at a time, when exhaust needs are greatest (for example, when most residents are cooking). Check local codes for minimum exhaust air requirements. Exhaust air volume should be slightly lower than the amount of air being supplied to the building through mechanical ventilation and natural infiltration.
- Check refrigerators for proper door closure. Refrigerators that do not properly close waste electricity and should be repaired. If repair is not possible, the refrigerator should be replaced.
