A new house wall system for residential buildings

Abstract

The residential housing sector consumes a significant amount of fossil fuel energy and thereby produces a large percentage of greenhouse gas emissions that contribute to global warming and climate change. At present, approximately 40% of the total household energy used is required for space heating/cooling and a substantial amount of that energy is lost through the house walls. Despite the importance of house walls for energy efficiency, most published literature focuses mainly on thermal comfort, environmental impact and economic costs of residential buildings. Little information is available on energy efficient house wall systems that can be used and adapted for varied climate conditions with minimal design change and associated cost. Therefore, the primary objective of this paper was to undertake a thermal performance study of two house wall systems with single and double glazed windows under variable climate conditions. The study was undertaken using thermal performance simulation software AccuRate®. The findings indicate that a significant energy saving can be achieved using the new house wall system compared to currently used brick veneer house wall system.

Application of passive wall systems for improving the energy efficiency in buildings: A comprehensive review

“…Aldawi et al [90] evaluated the thermal performance of two house wall systems under different climatic conditions in Australia. In this study, a proposed wall system with new configuration was compared to a wall system constructed by conventional method.…”

“…(see Table 6) [113]. The effective use Table 5 Conventional and new house wall components and their thicknesses [90]. of kinetic façades is dependent on controlling four major variables: solar thermal control, daylighting control, ventilation control, and energy generation [114].…”

Analysis of a wall cooling system using a heat pump

“…Offices were heated with four different heating systems: a floor heating system, two types of radiators and a wall heating system. Aldawi et al [22] compared the thermal performances of two house wall systems with single and double glazed windows under variable climate conditions. The study was undertaken using the thermal performance simulation software AccuRate ® .…”

Application of a ground source heat pump system with PCM‐embedded radiant wall heating for buildings

“…Radiant conditioning systems have been used for both heating and cooling in floors, ceilings, and walls recently. Thanks to these systems, the wished thermal comfort conditions are provided by using radiant conditioning systems . Ansuini et al studied PCM embedded radiant floor heating and cooling systems.…”
