‘Desigrated’ – Desiccant Integrated Façade System

‘Desigrated’ aims to integrate heat prevention strategies with low-ex cooling technologies, namely the desiccant and m-cycle evaporative cooling technology, in the form of a façade system for high-rise office buildings. The project aims to provide an alternative cooling solution for the hot and humid climate context of Bangkok. To achieve its goals, the project’s design approach is divided into two aspects: the vernacular approach and the constraints of the system.

The results from experiments by various researchers and literatures are used as assumptions in developing the system. Being one of the prominent dehumidification technologies, the Composite Silica Gel Heat Exchanger (CCHE) would be implemented as a primary part of the façade system, while the M-cycle technology would also be implemented as a secondary cooling technique to cool down the supply air. The evaluation shows a promising result, with up to 36% reduction in energy consumption in comparison with the conventional cooling system.
