The Shading Envelope: A morphology for climate change mitigation

Abstract

This paper presents the Shading Envelope (OE) which outlines the smallest volume to shade neighbouring properties during summer overheating periods. The construction method of the OE, by means of a parametric visual programming tool, is presented. The solar geometry data required for its construction is deduced from energy simulations with respect to the climate needs. The study of the impact of the proposed model shows a significant improvement in terms of minimizing summer solar radiation and increasing urban density.
