As our Partner had an innovative idea: To build Budapest’s first renewable energy powered residential park, we supported them from the very beginning. In the first phase of the planning process, our client had to see what the orientation, floor plan, mechanical alternatives of each building mean from an energy point of view, so we could measure the expected energy consumption. That was needed to find the best, most energy efficient solution.
We considered as a challenge that in multi-storey, multi-dwelling buildings, the roof area, which may be most suitable for renewable energy, is usually not large enough to approach near-zero energy demand, ie to cover it with almost 100% renewable energy. In such case, the point is on energy efficiency, the selection of ideal mechanical and architectural solutions, and t of the ideal roof geometry and orientation.
The dynamic simulation which takes into consideration both objects and topography, can be used to differentiate between various architectural forms, and helps find the most energy efficient design. We are able to determine the percentage of the annual consumption that can be covered by the expected yield. The outcomes of the two simulation below demonstrate sun exposure on both flat and pitched roofs. It is easy to guess which option we recommended to our Partner, as the flat roof simulation shows a higher sun exposure, which will create more yield during the year.
