  • Is it the most cost effective HVAC solution for this application considering whole of life costs?

  • Is the control system as simple as possible, consistent with achieving reasonable economy?

  • Would sub metering of air conditioning power use be appropriate?

  • What were the room temperatures at the time of the visit? Were these appropriate? Do occupants report that they are comfortable all year round? Are jumpers and jackets kept close at hand?

  • Are the thermostat set points appropriate? Are thermostats located away from heating or cooling devices? Can they be raised in summer or lowered in winter to save energy? Can the range of acceptable temperatures be expanded? Can temperature controls in corridors, lobbies, public spaces, and other areas be different according to the requirements for different spaces at different times of the day?

  • Can the chilled water or evaporator temperature controls be increased in cooler weather?

  • Can the heat load be reduced by reducing the solar heat load or by turning off equipment or activating energy star features on computers? Can plastic strip curtains, automatic doors, air curtains or weather screens in front of doors be used to reduce heat load?

  • Can heat loss / gain be reduced by insulating ducts, pipes, walls or roof spaces; painting outside surfaces light colours; tinting windows or closing drapes at certain times; and / or installing building shading devices ( incl trees)?

  • Is a good quality vapor barrier apparent? Are appropriate wall and roof insulation levels used? Could external shading be improved?

  • Are ceiling heights excessive? Could a false ceiling be installed?

  • Are outside doors fitted with automatic door closers?

  • Would ventilation of attics , equipment rooms and roof spaces be cost effective?

  • Are high efficiency filters used and outdoor air volumes reduced appropriately?

  • Are outside air levels appropriately matched to the need for outside air at different times? Can carbon dioxide sensing or other methods be used to control outside air? Are processes that contaminate the air isolated so that air changes for other areas are not excessive?

  • Is there excessive heat build up in the air plenums due to machinery or solar heat loads?

  • Is an economy cycle present / appropriate?

  • Can evaporative cooling be used either as the only source of cooling or to pre cool outside air for a refrigerative system?

  • Are zones appropriate for the buildings (during business hours and after hours)?

  • Is the system balanced adequately?

  • Is there any reheating of air present that could be avoided?

  • Is it possible that heating and cooing functions can operate at the same time or any other sequence overlapping occur?

  • Is any air leaking from air duct?

  • Optimised stop/ start or other start up later / switch off earlier operating time minimization strategy. Is any form of flushing / night purge used? Can heaters or chillers be switched off early as thermal inertia of building maintains conditions for some time?

  • Is air leaking from around doors and windows?

  • Can maximum demand be controlled to save operating costs?

  • Are uncontrolled room air conditioners present? Should they be interlocked with central system so that only one or the other can run at a time? Should time delay switches, time switches or some other controls be installed?
