REDUCING THE OVERHEATING PHENOMENON IN PASSIVE HOUSES BY INTEGRATING PHASE CHANGE MATERIALS
Abstract
This paper aims to provide an overview of the technologies for the use and implementation of phase change materials, with the purpose of identifying possible applications in energy efficiency, reducing energy losses and reducing carbon dioxide emissions, while bringing a contribution in identifying the applications in the design of passive houses regarding the reduction of the overheating phenomenon. A passive house can be defined as an energy efficient construction, which ensures an optimal indoor microclimate both in summer and winter time, thus ensuring an optimal indoor microclimate, without the need for a conventional heating or cooling source. Although the design concept of passive houses is a well-structured one, defined by a low energy consumption and a high degree of thermal insulation, as with any construction well insulated from the external environment, it is subject to the phenomenon of overheating of the interior environment, because of the heat gains inside the building, but also due to the insulation from external environment. The overheating phenomenon is a common problem found in most well-insulated buildings, such as passive houses, where although overheating prevention systems can be implemented, such as additional mechanical ventilation, natural-organized ventilation or the implementation of an active cooling system, these additional systems lead to additional energy consumption and additional running costs, or they can create an imbalance within the interior microclimate. The results of the study present the main relevant advantages that quantify the benefits of integrating phase change materials in the construction of passive houses, and the effect they have on reducing the overheating phenomenon, by creating a thermal management system through which the internal energy will not be lost, but will be stored and rendered to the environment without disturbing the interior microclimate and without the need for additional ventilation or active cooling systems.
