“…The results show that the PCM produces less temperature variation, twice longer discharge time, and higher and more stable heat supply than sand. In order to improve the energy performance of heating systems in buildings, Jin et al [101] developed a novel composite for use as a heat storage medium in heating systems in buildings. The composite has a thermal conductivity of 1.87 W/m and a latent heat of 161.9 kJ/kg.…”

The building sector is rated as a big consumer of electric energy and emissions, responsible for about 40% of final electric energy consumption. As a result, the Paris Agreement 2015 set a goal for buildings and the construction sector to reach a nearly zero-carbon stage by 2050. This urged most countries to create regulations for the construction sector and invest in energy efficiency programs. The present paper aims to present an updated review of building energy-saving solutions and techniques to contribute to carbon emission mitigation in the building sector. The high energy consumption of a building is mainly due to heating and cooling, which is directly related to the thermal properties of the materials used. Natural ventilation and illumination are other aspects that contribute to the high energy consumption. Considering these issues, the review covers energy-efficient construction materials such as mortars, concrete with PCM, new construction materials with PCM such as 3d printing concrete and geopolymer concrete, and bricks usually used in buildings. Also, the review covers the methods and solutions for energy saving for building heating and cooling. Since transparent windows and façades are essential for structures, their thermal and visual performance is crucial. Established and under-development techniques for windows and façades are presented and discussed. Walls and roofs are usually rated at the top of the weak barriers against a building's heat losses and energy gains. The present paper reviews existing and still under research and development techniques to improve the thermal performance of walls and roofs, such as cool roof and cool walls, walls and roofs with phase change materials (PCM), and ventilated walls and ceilings.Some authors’ comments are presented at the end of each topic. Some possible opportunities for future research and developments are also presented.

“…Energy consumption in buildings comes from heating, cooling, lighting and ventilation, which largely depends on the geographical locations, building types and climates. According to the specific working principle, LHTES integrated into the building energy con-servation can be categorized into passive and active applications [10,11].…”

“…Reviewing the literature indicates that for active thermal energy storage systems (ATES) in the RFHS, the application of a PCM is mainly focused on experimental studies, with an emphasis on the use of PCM materials in adjusting the temperature and encapsulating and embedding the PCMs in certain locations [21,25,29,30,32,34,37], floor construction and thickness optimization [28][29][30]33,36,38], and heating systems such as adjusting the temperature and flowrate of the supply water [21,27,31,39]. Portland cement is mainly used as a thermal storage cementitious material in ATES [27,[40][41][42][43].…”

The use of slag silicate cement mortar as a thermal mass layer for radiant floor heating systems holds significant potential for active thermal energy storage systems in buildings. The main objective of this article is to experimentally test the thermal performance of slag silicate cement mortar thermal storage blocks after the addition of phase change materials. The present study focuses on investigating the thermal performance of thermal storage blocks made of slag silicate cement mortar that incorporates a microencapsulated phase change material (mPCM). The mPCM consists of particles of paraffin-coated resin, which are uniformly distributed in the mortar. The analysis revealed that the introduction of mPCM particles into the mortar decreases the bulk density by approximately 9.4% for every 5% increase in mPCM particles ranging from 0% to 20%. The results obtained utilizing the Hot Disk characterization method demonstrate that the mPCM particles significantly affect the thermal properties of the mortar. Particularly, the thermal conductivity and thermal diffusion coefficient of the SSC30 mortar with a 17.31 wt.% mass of mPCM particles decreased by 59% and 69%, respectively. The results of this study provide a basis for the application of RFHS end-use thermal storage layers.
