By combining physics of structures with meteorology, properties of the building, weather conditions including outdoor temperature, wind speed and direction, as well as solar radiation can be taken into account.
The starting point for developing the method of eGain forecasting was the ENLOSS mathematical energy balance model developed by Prof. Roger Taesler [1] from Swedish Meteorological and Hydrological Institute in cooperation with Thorbjörn Geiser (member of the board) and Stefan Berglund,[2] who are currently both employed at eGain Sweden AB.
Until 2017 inclusive, forecasting method has been introduced in nearly 16 million square metres of floorage of residential buildings and commercial premises.
Recently, special remote control weather loggers have been introduced, and are used in combination with the forecasting receivers.
This turning point in technology provides an even more detailed analysis of the building and its environment, and thus improves the possibilities for control via this forecasting method.
