Charterhouse Square LOD4 3D Model

Crossrail is coming and it means lots of new train stations are going to be popping up around the city. In light of this, developers are looking at new ways they can utilise the space around these stations and this comes with a number of challenges surrounding light and space.

GIA have successfully completed a light pollution analysis for Charterhouse Square, where a Crossrail entrance is being built. Developers want to build a 5 storey office building above the station entrance and therefore the project involved carrying out several light analyses of the current area, and then comparing it to the predicted light pollution from the proposed building.

Currently Charterhouse Square is protected under English Heritage and therefore any developments which would cause a big disturbance to the character and ambience of the square would be prohibited so it was necessary to carry out a light pollution analysis of the area. The square is adorned with old gas lanterns along one side as well as minimal street lighting built into the façades of the buildings and therefore residents were keen to maintain the overall mood of the square.

GIA commissioned Vertex Modelling to capture a model of the area in order to carry out their research. The 3D model was created in 3 stages. In first stage we have created LOD3 model using high definition aerial imagery and stereo photogrammetry. Second stage involved an upgrade of the LOD3 models to LOD4 as this level of detail includes facade details. We have also upgraded railings and also modelled gas lamps important for the analysis.
Using this model GIA simulated stunted office lighting as well as retail shop front lighting in order to test the levels of light pollution from the proposed office block. Third stage of the site upgrade was general upgrade of any of the details that could affect the results of the light pollution study  including upgrade of trees to more realistic representation – trees were modelled with and without leaves to make sure the 3D model was accurate enough for the purposes of this study.
The study concluded that despite a new building being built above the Crossrail station entrance, there would be no significant changes in light patterns and the new building’s light would not compromise the ambience and overall atmosphere of the square.
