Climate and coloured walls, in search of visual comfort

摘要

The quality of natural light, the landscape surrounds and the techniques of construction are important factors in the selection of architectural colours. Observation of exterior walls in differentiated climates allows the recognition of particularities in the use of colour which satisfy the need for visual comfort. At a distance of 2000 kilometers along the coast of Peru, Lima and Mancora at 12°S and 4°S respectively, are well defined for their climatic characteristics: in Mancora sunlight causes high reflection, in Lima overcast sky and high humidity cause glare. The study of building colour effects at these locations serves to illustrate that colour values may be controlled in order to achieve visual comfort and contribute to colour identity.
