Summary: This paper examines residential heating patterns in and around Edinburgh, Scotland, UK, based on data from 255 homes. It compares empirical findings with the assumptions of the UK's Standard Assessment Procedure (SAP), revealing significant differences in indoor achieved temperatures and variations in heating use duration and timings across homes based on season and outdoor temperature. Little variation is found between weekdays and weekends or living space and other rooms, contrary to SAP assumptions.

Summary: In the context of the German energy transition, heat pump technology is explored as an alternative to traditional fossil fuel based boilers for sustainable heat supply. The transformation of a residential area in Germany into a zero-emissions district employing a heat-pump-based local heating system with hot water store is studied. The use of a mixing circuit or raising temperature spread in the evaporator are proposed as solutions to improve the efficiency of the heating system.

Summary: This paper proposes two novel control concepts to optimize the charging of domestic hot water (DHW) tanks in large buildings supplied by district heating systems. The first concept employs a smart energy meter, while the second concept uses staged proportional gain with an added temperature sensor. By implementing these control methods, comfort and hygienic requirements are met, and energy consumption and total flow are reduced.

Summary: To achieve the net-zero emissions goal in the UK by 2050, decarbonisation of domestic heating is crucial. Solar assisted air source heat pumps offer a promising alternative application under UK weather conditions. Different types of heat pumps show varying seasonal performance factors, with the serial type performing the best but requiring larger sizes of solar collector and thermal energy storage tank. Economic analyses suggest that parallel and dual-source heat pumps could be good replacements for gas-boiler heating systems.

Summary: Studying the resource consumption of social housing communities is crucial due to the scale of such programs. This paper provides a comprehensive literature review on the specific topic of domestic hot water consumption, highlighting the variations in approaches across different regions. The study also explores the efforts to integrate solar-based hot water solutions in social housing, particularly in high solar irradiance areas. User behavior is found to significantly influence hot water consumption, and lack of information about available hot water systems further contributes to this. The literature reveals common patterns in hot water consumption, such as peaks in the mornings and evenings and seasonal variations with lower usage during warmer periods.

Summary: Consumer demand is a key challenge in increasing renewable energy use. In the residential heating sector, consumer demand for renewable gases could play an important role in short-term decarbonization. However, existing research primarily focuses on the supply side and technical aspects, neglecting the demand side and consumer preferences.

Summary: Wastewater has significant potential as a source of clean energy. The use of shower heat exchangers seems to be the most reasonable solution, but the unwillingness of society to adopt this solution in Poland is a problem. To tackle this issue, the efficiency of a new compact shower heat exchanger and its linear counterpart was investigated, and the financial efficiency of using the compact heat exchanger with average water consumption for showering was evaluated. The study revealed that the compact shower heat exchanger has higher efficiency than its linear counterpart and is particularly beneficial when the building uses an electric hot water heater.
