TL;DR: In this article, a comprehensive review of the integration of phase change materials in building walls is presented. But, even if the integrated phase change material have a good potential for reducing energy demand, further investigations are needed to really assess their use.
Abstract: The present paper is the first comprehensive review of the integration of phase change materials in building walls. Many considerations are discussed in this paper including physical considerations about building envelope and phase change material, phase change material integration and thermophysical property measurements and various experimental and numerical studies concerning the integration. Even if the integrated phase change material have a good potential for reducing energy demand, further investigations are needed to really assess their use.

TL;DR: In this article, the authors investigated the use of phase-change materials (PCM) to maintain the temperature of the panels close to ambient, and showed that adding a PCM on the back of a solar panel can maintain the panel's operating temperature under 40°C for 80min under a constant solar radiation of 1000 W/m2.

TL;DR: In this article, the authors make an exhaustive technical review of the building envelope components and respective improvements from an energy efficiency perspective, including different types of energy efficient walls such as Trombe walls, ventilated walls, and glazed walls.
Abstract: A significant portion of the total primary energy is consumed by today's buildings in developed countries In many of these buildings, the energy consumption can be significantly reduced by adopting energy efficiency strategies Due to environmental concerns and the high cost of energy in recent years there has been a renewed interest in building energy efficiency This article strives to make an exhaustive technical review of the building envelope components and respective improvements from an energy efficiency perspective Different types of energy efficient walls such as Trombe walls, ventilated walls, and glazed walls are discussed Performance of different fenestration technologies including aerogel, vacuum glazing and frames are presented Advances in energy efficient roofs including the contemporary green roofs, photovoltaic roofs, radiant-transmittive barrier and evaporative roof cooling systems are discussed Various types of thermal insulation materials are enumerated along with selection criteria of these materials The effects of thermal mass and phase change material on building cooling/heating loads and peak loads are discussed Application of thermal mass as an energy saving method is more effective in places where the outside ambient air temperature differences between the days and nights are high Air tightness and infiltration of building envelopes are discussed as they play a crucial role in the energy consumption of a building Energy efficiency approaches sometimes might not require additional capital investment For example, a holistic energy efficient building design approach can reduce the size of mechanical systems compensating the additional cost of energy efficiency features
