“…The fact of the matter is that the growing consumption of energy sources is believed to be one of the considerable causes of environmental changes [2]. Referring to the United Nations Environment Program in 2016, households consume 40% of the primary energy (i.e., based on natural resources) in the world; hence, they are responsible for one-third of related global greenhouse gas (GHG) emissions [3,4]. In addition, energy as a determinant factor for the growing Iranian economy is mainly derived from natural resources [5].…”

This study seeks to find a method to identify the dominant pattern of energy choice and consumption in households, centering on demographic factors affecting the use of home appliances. To this aim, this study dealt with a variety of energy sources widely used by households, namely, liquefied petroleum gas (LPG), electricity, and kerosene for cooking, heating and cooling, lighting, and home appliances. Additionally, significant associations for the household energy choice and consumption were identified for demographic variables including household size, gender, head-of-household age, educational level, and income group. A logistic regression analysis was performed to obtain quantitative data provided by a survey from 821 households across residential districts of urban and rural areas in Mahabad city, northwest Iran. Obtained data were analyzed within a proposed three-energy dimension model (3-ED). The results showed that, in the case of other variables remaining constant, income may lead to variation in LPG and electricity consumption. Unlike other independent variables, the head-of-household age failed to have a significant impact. The findings can contribute to a better understanding of effective factors got household energy choice and consumption in other cities, and they can be useful for the support of policy-makers in their consumption patterns.

“…The energy consumption of the buildings is significant: they consume 40% of primary energy in the EU. [1] In addition, buildings are responsible for 33% of greenhouse gas emission in the EU and 39% in the USA. [1,2] The energy usage of heating is reducing due to different energy efficiency measures and therefore the exact knowledge of DHW consumption is getting more and more important.…”

“…[11] Individual metering also provides a great opportunity to decrease the DHW and space heating energy consumption in residential buildings since after the installation 15-20% of energy could be saved. [1] Individual metering also gives the possibility for consumerts to get details about their energy consumption. [12] The energy usage of the buildings is affected by different features.…”

The exact knowledge of DHW and heat consumption is necessary in the process of heat cost allocation and planning. In Hungary, heat cost allocation is based on summer months? heat demand. This method doesn?t lead to an accurate result due to the fact that the DHW demand varies throughout the year. There are several studies dealing with consumption data analisys, but only some of them have exact estimations on DHW usage patterns the Central-Eastern European countries. In this paper the DHW consumption was analysed in 115 ?commi block? buildings, which are common in Central-Eastern Europe and Russia and are usually connected to the district heating network. The examined buildings are located in Budapest, Hungary. The installation of the monitoring system has started in December 2012. The consumption data is collected since March 2014. The DHW usage was calculated in different cases for every month: per heated area, per heated volume and per flat. Average daily and annual data was also determined, the share of yearly DHW consumption over the months was calculated. The average daily and annual DHW consumption are 126 l/flat and 892 l/m2, respectively. The average net heat consumption is 28.2 kWhm-2a-1. Different DHW demand influencing factors were examined: the outdoor temperature and the residents? travelling habit is clearly influencing the DHW usage but no connection was found between the DHW consumption and economic indicators. The DHW consumption is approximately 30% higher in the winter than in the summer.

“…As a result, the thermal insulation of the pipelines was of very poor quality, the drainage was blocked and did not fulfill its function of preventing the flooding of networks, and the heating points in the buildings were not equipped with efficient systems for supplying heat to heating. The control of heat supply system depending on changes in the outdoor temperature was carried out centrally at the source [7][8][9][10].…”

The paper analyzes the connection diagrams and operation of buildings heat supply systems, taking into account the impact of changing weather and climate influences during the heating season. High-quality central heat consumption control was carried out, at which the heating carrier flow rate was maintained at a constant level, and its temperature varied according to a predetermined schedule. Thermal characteristics or mode of operation of the building differed from the data set in the schedule, as a result, more heat was consumed in certain periods. Its overrun was also observed during the warm period of the heating season, when, due to the maintenance of the hot water temperature at the right level on the outlet from the water-heaters, the heating carrier from the source was supplied with a temperature exceeding the established norms. The results of field tests and the diagrams of heat supply for heating at the heat supply operation in central heating points are presented. The main accent is made on the study of multi-circuit heating systems with frontal control of heat supply.
