Shadow Analysis

A shadow analysis is the study of how projected shadows from a structure or building will affect the surrounding buildings and environment in terms of the loss of received sunlight. A shadow analysis is fast becoming an integral part of many planning applications due to objections from neighbouring residents and their concerns about over shadowing of proposed new buildings or structures.
A shadow analysis can be referred to in a number of different ways

Shadow studies carried out by 3rd Dimension are done so on industry standard and recognised software that can illustrate the shadows cast by at any time of the day, any day of the month for any month of the year. A shadow diagram is a top down view of a digital 3D model which clearly shows the length of shadows that are cast. However a shadow study does not illustrate the density of such shadows as there are an infinitive number of options depending on the intensity of the sun on any given day or the level of cloud cover and their density. However a shadow study will clearly indicate if a proposed new structure or building will have a negative impact on surrounding existing buildings.
Shadow studies are being requested more and more by local planning authorities especially in AI or FI reports. 3rd Dimension are recognised by planning authorities as experts in the field of shadow studies.
Shadow studies carried out by 3rd Dimension are done so for the following three times of the year

We show the shadows cast on these days for the following times

These times of the day and months of the year are recognised as industry standard times as they cover

These times are chosen because on December 21st the sun is at its lowest and therefore this is the time of the year when the longest shadows are cast. On June 21st the sun is at its highest and therefore the shadows cast are at their shortest. And finally on March 21st the sun is located directly above the equator so is considered the middle of the spectrum.
A shadow analysis by 3rd Dimension is supported by a written report explaining the methodology and process behind the study. All rendered top down 3D images are produced at high and low resolution and issued on CD ROM. They are also produced in A3 pdf format showing all three times of the day for each of the three months under one another clearly showing the difference between the different times of the day for each month.
