building structures in subtropical regions

Dissertation – Developed to reduce Air-Conditioning
Residential Dwellings without the use of Air-Conditioning in Tropical and Subtropical Regions

Is it possible to entirely abolish energy-consuming air conditioning systems and simultaneously maintain a high living quality, a comfortable atmosphere and sufficient natural light in a living environment?

To find answers to this question, the dissertation will use completed case studies. The possibilities of abolishing a/c, will appear in building analyses, interviews with inhabitants and conclusions from detected (measured) air-humidity, surface-temperature and thermal-mass.

The substantial questions are: Which existing knowledge and which architectural strategies must be combined and modified to create the optimal system in respect to building energy consumption and low carbon sustainability? What is their impact in terms of architectural design? How will these conditions influence the typologies, floor plans and building typologies in housing construction?
The dissertation will clarify the challenges in the design processes to realize those typologies in tropical and subtropical conditions.
Individual behaviour is one relevant aspect to solve those problems. Social strategies supporting the aim will be shown.

The dissertation focuses as its central theme, how the design of a building and façade structures can affect good living quality and interior climate in tropical and subtropical regions without the use of a/c.
