##Opportunity The Haller development appeared on the real estate market as a pioneer, our client is developing a premium segment with the potential of decreased living costs and truly sustainable living.
##Challenges The main challenge was only being able to use buildings 1 and 2 due to building regulations: As a result of 3D simulation we received inadequate shade/light ratio because of the roof mounted HVAC system and the noise wall. Therefore we had to be creative and evaluate a more efficient solar panel system.
##Solutions Due to lack of suitable surfaces for solar modules fitting, it was suggested to build some pergolas. It was necessary to keep the pergola in a range of 40° from the walls.
