Systematic Integration of Energy-Optimal Buildings With District Networks

François Maréchal, Luc Girardin, Ivan Daniel Kantor, Paul Michael Stadler, Raluca-Ancuta Suciu

The residential sector accounts for a large share of worldwide energy consumption, yet is difficult to characterise, since consumption profiles depend on several factors from geographical location to individual building occupant behaviour. Given this diffi ...
