Waste heat plays a significant role in obtaining the 4th and 5th generation of District Heating (DH) System in cities. This article presents the possibilities of integrating selected waste heat emitters into DH, with the objective of meeting the demand for heat for the selected residential area (approx. 4000 inhabitants) in the city of Gliwice (180 000 inhabitants). The total heating demand of the studied area was estimated at 19 800 GJ including both space heating and domestic hot water. The maximum thermal power was estimated at approx. 2.45 MW. The demand was calculated on the basis of registered metering values for individual buildings which were processed and summarized due to the lack of collective meters for the district. A detailed data classification, correction and completion procedure was elaborated to deal with non-uniform and low-quality data registration. Two industrial objects with waste heat generation were examined to be integrated with the local DH network. The waste heat generation potential equals 9.0 MW for plant #1 and 0.9 MW for plant #2. Apart from the constant generation declared by the industrial entities, realistic profiles including possible shaft-work and maintenance periods were created. It has been shown that the total heat demand for selected residential areas can be covered by integrating waste heat into the current DH network. Depending on the waste heat generation profile, the local area heat demand can be covered entirely or to a large degree (coverage factor ranges from 72 to 100%). The waste heat utilization factor ranges from 6.3 to 8.3%. To manage the remaining waste heat potential, it is required to build additional district heating pipelines and nodes connecting to the existing network to receive an additional 7.45 MW thermal power. The potential of waste heat recovery is significant at the scale of a medium sized city: integrating two large industrial emitters allows up to 13% decarbonization of heats production in the local district heating plan.

In construction, textiles can be used either for reinforcing the structure or for finishing design. When we talk about function, the interior is no less important than the exterior and architecture of the building. Thus using textiles to reinforce the structure of buildings, textiles often perform a desired function of reinforcing the “finish.” Building textile materials include fibers that are mixed with concrete, fiberglass reinforcement meshes, insulators, etc. Textile architecture covers permanent tensile structures based on polyester or glass fiber fabrics, with polyvinyl chloride (PVC) or polytetrafluoroethylene (PTFE) coating and awnings generally supported by polyester or polyolefin fabrics, with or without coating, especially for gardening. All above topics are covered within this perspective with the experts from the group of smart textiles for building and living within COST Action CA17107 European Network to Connect Research and Innovation Efforts on Advanced Smart Textiles (CONTEXT) [1].

The analysis of final energy consumption for heating in 74 rural communities of Lubuskie province is presented. Annual energy consumption in rural areas in the region was estimated based on models describing the final energy consumption in all objects in rural area. Heated buildings are divided into three sectors: housing, social and economic infrastructure, and agricultural production. The annual final energy consumption is about 18.6 PJ. The housing sector, consumes 15.6 PJ of energy, which amounts to 83% of the total thermal energy consumption in rural areas the province. The primary carrier of energy in rural areas is coal and biomass, which share in the structure of fuel consumption is respectively 62 and 19%.

Przedstawiono analizę zużycia energii finalnej na ogrzewanie w 74 gminach wiejskich województwa lubuskiego. Roczne zużycie energii na terenach wiejskich województwa oszacowano w oparciu o modele opisujące zużycie energii finalnej we wszystkich obiektach wiejskich. Dla potrzeb pracy obiekty na terenie gminy podzielono na trzy sektory: mieszkaniowy, infrastruktury społeczno-ekonomicznej, oraz rolniczo-produkcyjny. Roczne zużycie energii finalnej wynosi ok. 18,6 PJ. Największym konsumentem jest sektor mieszkaniowy, który zużywa 15,6 PJ energii, co stanowi 83% całkowitego zużycia energii cieplnej na obszarach wiejskich województwa. Podstawowym nośnikiem energetycznym na obszarach wiejskich województwa lubuskiego jest węgiel kamienny oraz biomasa, których udział w strukturze zużywanych paliw wynosi odpowiednio 62 i 19%.

The characteristics of territorial distribution of greenhouse gas emission sources have been analyzed for eastern Polish regions. Mathematical models and information technology for spatial analysis of greenhouse gas emissions from fossil fuel consumption of heat/power plants and households have been developed in consideration of the territorial distribution of greenhouse gas emission sources and structure of statistical data for the Polish voivodships: lubelskie, podkarpackie, podlaskie, and świętokrzyskie. The results of spatial analysis for these eastern voivodeships are presented in the form of thematic maps. Key words: information technology, spatial analysis, greenhouse gas emissions, heat/power plant, residential sector, fossil fuel.

W Polsce na ogrzewanie i przygotowanie ciepłej wody w sektorze komunalno-bytowym zużywa się obecnie około 42% globalnego zużycia energii pierwotnej, w tym mieszkalnictwo 35%, a budynki użyteczności publicznej handlu i usług ok. 7%. Dla porównania w UE odsetek ten wynosi 30-35%. Zrozumiałe jest więc, że w dalszej części artykułu szczególną uwagę poświęcono analizie sektora mieszkaniowego.
