Trombe Wall Performance in Multiple Climates: A Simulation Study

Global warming is an increasing concern worldwide, with energy production enhancement being one of the contributing factors. By 2040, the global energy demand is projected to increase by approximately one-third. This paper proposes a study on the efficiency of implementing a simple Trombe wall structure to passively gain solar energy and heat or cool a space. The methodology involves using computational data on heating and cooling energy loads via simulations in the DesignBuilder software. Fifteen climate zones were selected according to the Koppen-Geiger climate classification map, and appropriate building envelopes and simulations were modeled and conducted. The results were controversial for some climate zones and required further investigation. The simulation data demonstrated the efficiency of the Trombe wall installation in one zone and showed its inappropriateness for another climate classification. The specific composition of the wall, roof, and other building structures is crucial for particular climate zones. Another potential reason for Trombe wall performance being negative in terms of energy-saving parameters in heating-dominant zones is the climate classification issue.
