Creates an individual configuration for the evolutionary algorithm. The individual is divided into four parts namely Heating technologies, Cooling Technologies, Heating Network and Cooling Network Heating Technologies: This block consists of heating technologies associated with % of the peak capacity each technology is going to supply, i.e. 10.1520.2030, which translates into technology 1 corresponding to 15% of peak capacity, technology 2 corresponding to 20% and technology 3 corresponding to 0%. 0% can also be just done by replacing 3 with 0. The technologies block is then followed by supply temperature of the DHN and the number of units it is supplied to among AHU, ARU, SHU. So if it is 6 degrees C supplied by DHN to AHU and ARU, it is represented as 6.02. The temperature is represented with 1 decimal point. Cooling Technologies: This follows the same syntax as heating technologies, but will be represented with cooling technologies. The block length of heating and cooling can be different. Heating Network: Network of buildings connected to centralized heating Cooling Network: Network of buildings connected to centralized cooling. Both these networks can be different, and will always have a fixed length corresponding to the total number of buildings in the neighborhood :param nBuildings: number of buildings :type nBuildings: int :return: individual: representation of values taken by the individual :rtype: list
