With the rise of all-electric buildings the load on the electrical grid grows. This could slow down the energy transition and densification of existing neighbourhoods as the current grid is not capable to withstand a higher load. This research gathers literature on different peak shaving techniques to create a clear overview and investigates the impact on the load profile when techniques are combined. This new insight in combined techniques will provide a solid basis to develop a more detailed modelling tool to simulate the actual energy use and generation on a daily and annual basis. The load profiles of these techniques are combined with the existing energy demand curve to see how these techniques reduce peak loads that occur during the day. To asses the influence on the annual load curve the ZED-tool was used to simulate peak shaving techniques on a case-study building. The results show that a combination of outside insulation, sun shading and a heat pump flatten the daily and annual load profile significantly. However the implementation of east and west facing façade PV in combination with wind energy decreases the peak loads the most. Finally when all techniques are combined with a battery a building block can become not only energy neutral but almost self sufficient.
These research results were developed into a design for the renovation of a post-war appartmentbuilding in Haarlem Schalkwijk. In the new design other topics like densification, flexibility and climate adaptation were addressed as well to improve the post-war neighbourhood. This design is a base for a bigger renovation strategy that could be implemented in multiple post-war neighbourhoods in the Netherlands.

A House For Cheerful Living
An exploration of architectural representation in post-war housing competitions
Post-war housing competitions were held during the second World War to provide solution for the housing shortage. Looking at the drawings made for these competitions we can see that a similar style is used.
Through analysis and comparison of a drawing made by Jean Bodman and one made by Don Knorr, this thesis explores the similarities in drawing style. By comparing the education of the two architects we attempt to comprehend what could influence the similarities in drawing style.
The analyses shows that the drawing style and architectural style are similar, however a different emotion is depicted in the drawings. The fact that these architects were educated around the same period and were both mentored by famous modernist figures like Walter Gropius and Eero Saarinen is evidence for the similarities in drawing style. Furthermore, Norman and Donald worked both at SOM could also explain the similarities, while Norman also worked on the House for Cheerful Living project. However, it is difficult to say how the similarities came to be and if these arrived from related influences. The differences in depicted emotion could be explained by the fact that the drawings were made for a different audience. ...
