“…Other studies have also shown that it is important to consider the thermal mass of furniture, especially in lightweight structure buildings [28,29]. The furniture is usually represented by simplified geometries in such analysis [30][31][32]. Wallentén [33] measured the heat transfer coefficient of walls of a room with and without furniture the effect of the furniture was not significant in this study.…”

Radiators play an important role in providing a comfortable and safe indoor environment while maintaining high-energy efficiency. In the perspective of future climate change with expected larger temperature fluctuations and the rapidly changing heat supply and demand, it is required that the current radiator technology is adaptable. The heat supply is changing towards a lower supply temperature to enable an increase in energy efficiency and an increase in the share of renewable energy. Simultaneously, both the heat supply and demand are expected to have more variations in the future. An additional concern that has come into more focus after the experience with the COVID 19 pandemic is the prevention of the spread of infection in indoor environments. Researchers have extensively studied several innovations in radiator technologies and their deployment that addresses these challenges. Some of the solutions available in the literature include floor heating, ceiling heating, ventilation radiator, stratum ventilation. Researchers have used advanced modeling and experimental techniques to understand how to deploy different types of radiator technologies. This review summarizes solutions in the literature that address these challenges and identifies knowledge gaps that need to be addressed. In particular, this study explores the gaps in knowledge of practical issues, such as the position of furniture and the position of people, which have received less attention in the literature. Research that addresses the effect of radiators on ventilation and a healthy indoor environment is also of particular interest in this review.

“…Recent R&D focus on the thermal mass topic lies on the development of optimal operation strategies for building thermal processes, taking the TES by thermal mass factor into account. These thermal mass include the building structure (external and internal walls) [209], earths [92], internal furniture and contents [97,98], stored products in warehouses [201], or water-filled containers [99]. Some examples are shown in Fig.…”

This chapter presents a state-of-the-art review on the available thermal energy storage (TES) technologies by sensible heat for building applications. After a brief introduction, the basic principles and the required features for desired sensible heat storage are summarized. Then, material candidates and recent advances on sensible heat or cold storage adapted for building application are discussed, each with its own characteristics, advantages, and limitations. A large section of the chapter is devoted to the sensible TES technologies for buildings, both for short-term (daily) and for long-term (seasonal) storage. Each technology is described in detail including different aspects: basic principle, development status, performance and costs, potential and barriers, today's R&D activity focus, etc. Comparisons on the advantages and limitations between different TES technologies are also made. Finally, conclusions and future directions are summarized.

“…Reynders et al used the structural thermal storage for demand-side management, offering the flexibility to improve the balance between electricity demand and production [9]. Besides indoor air and building envelope, Li et al also considered thermal mass of furniture in buildings and proposed a new method to calculate the equivalent thermal mass of actual furniture which has irregular shapes [10]. To quantify energy flexibility in buildings, Hurtado et al utilized several parameters including comfort capacity which represents the maximum response time before reaching comfort limits to describe the flexibility action of buildings [11].…”

With the growing penetration of RES, more flexibility is required in power system. District heating system with large capacity is able to offer flexibility to power system. Based on the model of a district heating system built by heat current method, this work proposes a quantification method to evaluate the flexibility of district heating system, which is a hybrid algorithm utilizing simulations and dichotomy method. Quantitative indicators including average power shifting capability and available storage capacity are defined to describe the flexibility. The results of case study present the flexibility of system under a general working condition. Then, influence factors are discussed that with the increase of dispatch time and decrease of the time of heat migration delay, the storage capacity of heating network increases.
