“…The scientific community is working hard to popularize ESBs. In the recent past, the energy, environmental, and economic performance of these buildings have been the subject of many studies and projects in different countries: Nigeria [44], China [45], Egypt [46], Russia [47], the USA [48], Brazil [49], Iran [50], etc. On the other side, the negligible presence of ESBs on the territory of Serbia (despite a certain number of works by Milanović [51,52] and Nešović [53,54]), both in traditional and contemporary architecture, has a multi-layered background: historical, cultural, sociological, economic, climatic, typological, and pedological.…”

The global scientific community is intensively promoting energy-plus buildings. Following the leading world trends, this paper presents a new energy-plus building concept—elevational earth-sheltered buildings with three different types of horizontal overhang photovoltaic-integrated panels: wooden support columns covered with clay tiles, steel pipes as support columns covered with sheet steel, and concrete support columns with concrete coverage. In this instance, the specific multi-numerical case study building model for the city of Kragujevac (located in central Serbia with favorable climatic conditions) was performed over 7 months (from 1 October to 30 April), taking into account the soil temperature, the effects of solar shading, the performance of the heating system—a ground source heat pump—and the characteristics of the artificial and automatic lighting control system. The simulation results show that the optimal depth of a horizontal overhang (energy-plus status) depends on the occupant’s habits, in addition to meteorological conditions. The presented methodology can be used for any other location, both in Europe and the world.

“…Currently, fossil energy constitutes the largest proportion of the overall energy structure [1]. However, due to the non-renewable nature of fossil energy and its detrimental impact on the environment, it has become a bottleneck for economic and social development [2][3][4]. As a major energy consumer, the building sector urgently requires the coordinated development of energy, the economy, and environmental protection.…”

Biogas heating plays a crucial role in the transition to clean energy and the mitigation of agricultural pollution. To address the issue of low biogas production during winter, the implementation of a multi-energy complementary system has become essential for ensuring heating stability. To guarantee the economy, stability, and energy-saving operation of the heating system, this study proposes coupling biogas and solar energy with a phase-change energy-storage heating system. The mathematical model of the heating system was developed, taking an office building in Xilin Hot, Inner Mongolia (43.96000° N, 116.03000° E) as a case study. Additionally, the Sparrow Search Algorithm (SSA) was employed to determine equipment selection and optimize the dynamic operation strategy, considering the minimum cost and the balance between the supply and demand of the building load. The operating economy was evaluated using metrics such as payback period, load ratio, and daily rate of return. The results demonstrate that the multi-energy complementary heating system, with a balanced supply and demand, yields significant economic benefits compared to the central heating system, with a payback period of 4.15 years and a daily return rate of 32.97% under the most unfavorable working conditions. Moreover, the development of a daily optimization strategy holds practical engineering significance, and the optimal scheduling of the multi-energy complementary system, with a balance of supply and demand, is realized.
