This paper is devoted to the issue of post-war reconstruction of damaged buildings and, in particular, panel construction as the most massive in Ukraine. The main structural features of large panel system (LPS) buildings are given and the existing experience of their renovation. Taking into account the state of the industrial base in Ukraine and the impossibility of quick rebuilding of panel houses from the elements of this construction system (precast panels), a new precast-monolithic frame is proposed, which is based on the production of structural elements in a permanent formwork printed using a 3DCP. Basic solutions for columns, beams and slabs have been developed. As an implementation, numerical simulation of a damaged 16-storey panel building with the proposed superstructure system is performed. The obtained results confirmed compliance with all the requirements of regulatory documents for the ULS and SLS limit states and al-lowed the reconstruction of the building to be implemented.

“…In [34], the authors presented an assessment of measured energy consumption for space heating of 10 multifamily buildings during the 2002-2020 period, including pre-and post-modernisation conditions. Implemented retrofit measures resulted in annual heating demand lowering from 19.8% to 35%.…”

Audit-Based Energy Performance Analysis of Multifamily Buildings in South-East Poland

Multifamily buildings account for about half of all residential buildings in Poland and about 70% of the urban population live in them. Most of them require thermal refurbishment. Evaluation of a building’s energy performance with the use of correlation models has been very rarely used in relation to buildings in Poland. This method is simple, fast and can improve the decision process on thermal modernisation. It is especially important at the pre-design stage of planned investments. This paper presents an attempt to develop correlations that could be used in the energy assessment of multifamily buildings. For this purpose a dataset containing of 29 audits of multifamily buildings was used. The statistical analysis was performed for buildings before and after planned refurbishment. Obtained relationships showed strong correlation between thermal demand for space heating or domestic hot water and ventilation airflow and thermal transmittance of windows (R2 > 0.6). After designed modernisation the number of strong correlations decreased. Energy for domestic hot water was correlated with the number of inhabitants (R2 = 0.6). Energy for space heating was correlated with the number of users and heated volume of a building.

“…Despite the increasing demand for energy efficiency, the full potential of energy efficiency remains Energies 2024, 17, 2601 2 of 24 limitless; many buildings in the EU consume more energy than expected. Collecting data and developing models to predict occupant behavior is the next step in sustainable design [7][8][9][10][11]. Hybrid heating systems based on the use of an air or ground heat pump (HP), photovoltaic panels, and an additional peak heat source (e.g., gas boiler) are becoming more and more popular [12][13][14][15][16][17][18].…”

This study evaluates a hybrid heating system in a single-family building in northeastern Poland, which has a temperate continental climate. The analysis covers two heating seasons in 2021/2022 and 2022/2023. The hybrid heating system includes an air heat pump HPA–08 CS Plus with a heating power of 8.2 kW (AHP), a condensing gas boiler VC146/5–5 with a power of 14 kW (GB–Condens.), and a solid fuel boiler with a power of 11 kW for central heating. Additionally, hot water is heated by a Basic 270 (DHW’s AHP) air–water heat pump with a power of 2 kW, utilizing a tank with a capacity of 270 dm3 equipped with two heating coils. The building’s average electricity consumption is around 5400 kWh/year. A 4.96 kWp photovoltaic installation is installed on the building’s roof at a 40° angle towards the south to supplement the hybrid system. The study aims to assess whether the PV installation can adequately cover the energy needs of the hybrid heat source for heating and hot water. Furthermore, the study calculates the emission of pollutants (CO2, SOx, NOx, CO, and PM10) into the atmosphere. The total annual electricity production from PV installations was 5444.9 kWh in 2021/2022 and 5684.8 kWh in 2022/2023. The excess electricity was stored in the PGE power grid as per the Prosumer settlement rules. The installed PV installation is sufficient to power the following devices annually: AHP, DHW’s AHP, and GB–Condens. However, the daily electricity production from the PV installation is not enough to cover the energy needs of the heat pump for heating during the cold months in Poland (I–III, XI–XII). It can meet the power needs of a PC all year round and can also be stored during the summer months, for example, in energy warehouses or by directly storing it in the PGE power grid. The use of the PV installation resulted in an average reduction in pollutant emissions into the atmosphere: CO2—94.1%, SOx—91.8%, NOx—95.6%, CO—9.7%, and PM10—32.1%.
