The objective of the project ‘Energy Wise Cities’ (EKAT) is to elevate the cities involved into internationally aspirational areas in energy-efficient living, zero-energy construction, the implementation of a multiform energy system, monitoring energy-efficiency and user guidance. The EKAT project works towards the following objectives: • The creation of a simulation model that enables the design and implementation of a regional energy-wise area and quarter connected to the rest of the energy grid via intelligent control systems. • The development of concepts of intelligent and energy-wise buildings, the identification of essential data flows for the optimal control of the building and the development of data collection for depicting the use of the building in cooperation with companies. • The promotion of new business opportunities and energy efficiency partnership models in order to achieve the objectives of the national energy efficiency agreement. • The development of city planning tools for designing areas closing in on zero energy as well as the overall optimisation of regional energy systems.
