Special Issue Information

Dear Colleagues,

Globally relevant scientific and research topics, as well as experience gained during a research internship, has led us to address issues related to energy efficiency in buildings from a general and broad perspective. Therefore, we are pleased to introduce this Special Issue of Sustainability, entitled "Energy- and Cost-effective Building Construction and Renovation Combining New Solutions, Renewables, and Waste Heat". This Special Issue will collect scientific papers, case-studies, and review papers on the applications of renewable energy sources, the use of waste energy, and methods of improving energy efficiency in newly constructed or modernized buildings.

We welcome the submission of works addressing energy, economy, and combined issues, in the scope of, but not limited to, the following topics:

  • Heating, cooling, and electricity supply systems for buildings.
  • Building technical equipment systems.
  • Pro-environmental and sustainable techniques for erecting or renovating buildings.
  • Thermal comfort.
  • Effective control of the efficiency of energy supply systems.
  • Energy and its savings.
  • Usage of renewables for heating, cooling, and electricity supply in buildings.
  • New equipment/technologies for energy-efficient and sustainable buildings.
  • HVAC systems.

We welcome submissions from scientists, tertiary-level education staff, and professionals within the following fields: architecture, civil engineering, environmental engineering, electrical engineering, HVAC systems, mechanical engineering, automatization, and controlling engineering. We are pleased to invite you to share your knowledge and experiences related to the energy-efficient renovation of buildings and the construction of energy systems for buildings, focused on the usage of renewable- or waste-heat-derived energies.

We believe this Special Issue will shed new light in the topic of energy- and cost-effective building construction and renovation combining new solutions, renewables, and waste heat.

The use of greywater heat exchangers (GHEs) is an effective way to reduce energy consumption for heating domestic water. However, the available characteristics of this type of device are often insufficient and consider only a few selected parameters of water and greywater, which results in the need to look for tools enabling the determination of the effectiveness of GHEs in various operating conditions with incomplete input data. The aim of this paper was to determine the usefulness of artificial neural networks (ANNs). For this purpose, comprehensive experimental tests were carried out on the effectiveness of the horizontal heat exchanger, taking into account a wide range of water and greywater flow rates and temperatures of these media, as well as the linear bottom slope of the unit, which allowed for the creation of a database of 32,175 results. Then, the feasibility of implementing the full research plan was assessed using ANNs. The analysis showed that the impact of the media temperatures on the heat exchanger effectiveness values obtained using ANNs is limited, which makes it possible to significantly reduce the number of necessary experiments. Adopting only three temperature values of at least one medium allowed the generation of ANN models with coefficient values R2 = 0.748–0.999 and RMSE = 0.077–1.872. In the case of the tested GHE, the slope and the flow rate of the mixed water are of key importance. However, even in the case of parameters of significant importance, it is possible to reduce the research plan without compromising the final results. Assuming five different values for each of the four input parameters (a total of 625 combinations) made it possible to generate an ANN model (R2 = 0.993 and RMSE = 0.311) with high generalization ability on the full research plan covering 32,175 cases. Therefore, the conducted analysis confirmed the usefulness of ANNs in assessing the effectiveness of GHEs in various operating conditions. The approach described in this paper is important for both environmental and economic reasons, as it allows for reducing the consumption of water and energy, which are necessary to carry out such scientific research.

This article analyzes the possibility of reducing the energy consumption from building heating as a result of lowering the indoor air temperature, which is recommended as a response to the energy crisis. Various values of the set-point temperature (16–22 °C), as well as different scenarios for their changes, were assumed for analysis. Changes in clothing that were determined to maintain the same level of thermal comfort after a temperature change were determined. The associated reduction in CO2 emissions emitted into the atmosphere was determined. The effect of reducing CO2 emissions was studied depending on the type of heating source. Simulation calculations were carried out for an exemplary multifamily building. The effect of different building insulations required in Poland over the years 1964–2022 was considered. Analyses were performed for the climatic conditions of cities located in different climatic zones of Poland: Koszalin, Wroclaw, Warsaw, Bialystok, Suwalki. Depending on the scenario, the insulation standard of the building, and the variant of location, the energy reduction achieved ranges from 6.6%/K to 13.2%/K. Taking into account the type of heating source, the reduction in CO2 emissions is from 0.7 to 7.5 kgCO2/(K·m2). The reduction in temperature by 1 or 2 K can be compensated for by wearing an additional sleeveless vest (0.12 clo) or sweater (0.28 clo). Full article

The background of this article is the potential energy savings of solar heat supply systems due to the use of the renewable energy of solar radiation. The motivation is to create a solar collector design that would combine the functions of both a building cover and a solar collector. It is necessary to investigate and compare different types of solar collector coatings (traditional and modern) and pipe diameters. The purpose of the article is to solve aspects of energy efficiency for new eco-friendly solar collectors. The most effective result occurred with the solar collector covered with the rubber–graphite composition of Grafplast PDA, and when using Prandelli/Tuborama pipes with a diameter of 0.016 m. Their efficiency increased by 8% compared to the second version of the collector made using a more traditional solution. The influence of the distance between the pipes and the flow rate of the heat carrier on the efficiency of the solar collectors was evaluated. Full article
