Abstract

The utilization of point cloud as a 3D laser scanning product has reached across
multi-disciplines in terms of data processing, data visualization, and data
analysis. This study particularly investigates further the use of typical attributes
of raw point cloud data consisting of XYZ (position information), RGB (colour
information) and I (intensity information). By exploring the optical and thermal
properties of the given point cloud data, it aims at compensating the material and
texture information that is usually remained behind by architects during the
conceptual design stage. Calculation of the albedo, emissivity and the reflectance
values from the existing context specifically direct the architects to predict the
type of materials for the proposed design in order to keep the balance of the
surrounding Urban Heat Island (UHI) effect. Therefore, architects can have a
comprehensive analysis of the existing context to deal with the microclimate
condition before a design decision phase
