The extent of energy loss through the opening in the lift shaft head of a building depends on a variety of factors. Examples are the dimensions of the lift shaft and ventilation opening, room temperature, building use and the installed heating system.
Using the real facts of your building and its usage details, the BlueKit simulation programme calculates the potential annual savings in kWh, CO2 and heating costs through the installation of a lift shaft smoke extraction system. Regional meteorological data from throughout Europe is fed into the tool, which registers the difference between mean monthly daytime and night time temperatures and the charge you are paying per kWh. The resultant report contains a payback calculation including the maximum savings across a ten-year period.
