Thermal Performance Analysis of a Liquid Wall vs. Argon-Filled Double Glass in Identical Prototype Buildings

This study investigates the thermal performance of a liquid wall panel compared to an argon-filled double-glass window in identical prototype buildings located in Tirana, Albania. The analysis considers heat transfer mechanisms, thermal resistance, thermal mass, energy storage, transient heat transfer dynamics and CO2 emissions. The study quantifies the thermal efficiency of each system using U-values and heat storage capacity, comparing their overall effectiveness in reducing heat losses and maintaining internal comfort. Water walls can contribute to increasing the indoor thermal comfort of the inhabitants. Temperature fluctuations in the indoor area as a result of water wall implementation will be lower, furthermore, indoor human comfort will be optimized. Implementation of water as an element in such type of facades can be risky due to impurities, transparency, visibility, and health problems. In order to evaluate its thermal performance and the impact in the indoor area, typical calculations will be applied, drawing conclusions. The thermal performance of the water wall is influenced by the design of the system, weather conditions, and materials used. The system can contribute to achieving a sustainable building certification. Water walls can be effective passing cooling strategies in certain climates, but it is needed to pay attention to the design, maintenance, and environmental conditions.
