A case study of green building design process.

Sustainable architecture design with Shadow Analysis

A case study of car dealership shows how Shadow Analysis can be incorporated into green building design process. Car dealership building usually features largely glazed elevations with spaces very high ceiling behind them, this presents a set of challenges regarding building energy efficiency. This usually leads to issues with overheating in cooling season and heat losses during the heating season. Uneven distribution of temperature inside can also cause issues with indoor microclimate. Architects of this project decided to solve all these problems with a canopy design which would cast a shadow during summer and provide sunlight in winter.




Canopy designed optimised with Shadow Analysis provides a lot of light to get in during winter


Shadow study (above) shows an impact of the designed canopy on the glazed facade. During the heating season windows are exposed to sunlight, this will have a positive impact on heating and lighting requirements of this space. In cooling season canopy cased shadow over glazed elevation, this will reduce cooling requirements as well as reduce light intensify (daylight during summer is usually to intensive for comfortable interior conditions). All these matters are very impotent in sustainable design and in acquiring energy efficient building certificates like LEED or BREEAM.

Below are few images of the final design.
