Building Air Infiltration
- Building Infiltration Sealing
- Attic Insulation
- Window Replacements
- Door Replacements
- Roof Replacement
The Investment Grade Energy Audit found every City building to have varying levels of air leakage that warranted implementation. Therefore, caulking, foam, and weather-stripping work was done to reduce air leakage from windows (some windows were also replaced), roof/wall and floor/wall intersections, vents, and wire passages. Additionally, loose fill cellulose insulation was added in the walls and attics of many buildings.
Building Automation Controls (upgrading the existing ones or installing the new ones)
- Time of Day Scheduling (regulates building occupancy for each zone and time period)
- Demand Control Ventilation (modulates the outside air settings to match the actual needs of the space, which prevents over-ventilation of these spaces and results in lower heating and cooling costs)
- Optimum Start/Stop (delays the start of a building’s primary heating, ventilating and air conditioning equipment until the last possible moment necessary to ensure a comfortable environment for the occupants)
- Occupancy Sensor Control (sets back space temperature when rooms are unoccupied)
The IGA found that a large number of City buildings suffered from inefficient and outdated heating and cooling control equipment, such as older, non-compatible energy management systems, non-programmable thermostats, simple valves to control radiators, and inefficient night temperature controls and boiler burners.
Therefore, the City decided to replace a variety of outdated equipment with a modern energy management system which can be programmed, monitored and controlled remotely.
Computer Power Management
The City installed a computer management software program that allows for remote power control of the City’s approximately 6,200 computers. Prior to this improvement, computers were typically not shut off at night or on weekends due to the need to install security upgrades. By installing remote power control, the City’s Technical Services Division is now able to send computers into hibernation mode during non-working hours and power them on remotely to install updates as needed.
