Reducing energy consumption, increasing energy efficiency technologies and solutions, decreasing emissions are very effective tools towards EU environmental policy. The constant demand for domestic hot water (DHW) throughout the year creates great benefits for drain water heat recovery (DWHR) systems in hotels, which is the most promising and significant feature of energy saving potential for the hotel sector in Poland. This paper determines the feasibility of heat recovery in a typical hotel in Poland. The energy analysis was carried out for the installed DWHR system (from washbasins and showers) at the hotel building. To evaluate the energy saving potentiality, daily, monthly and yearly calculation results were performed for an exemplary hotel in Poland. Two types of heat exchangers were adopted for further calculations: vertical (System 1) and horizontal (System 2), this intention aimed to find the most efficient type and relevant solution of energy saving and reduction of CO2 emissions in the analysed hotel. The analysis and calculations were repeated to enhance the saving potentiality of the proposed DWHR systems for various parameters like constant and variable temperature of supply cold water, daily hot water consumption profiles, the efficiency of heat recovery, reduction of annual carbon dioxide emission (CDE), facility standard of operating procedure, the impact of hotel size, etc. The obtained results of the conducted calculations ensure a significant potential of energy savings by implementing the proposed DWHR systems in analysed hotel, which allow to save energy demand and to reduce CO2 emission by 27.3% and improve the efficiency of the DHW preparation system.

The renewable and waste heat sources implemented for the preparation of domestic hot water (DHW) allow for energy conservation and environment protection along with resource savings and economic benefits. The solutions, including non-conventional sources, are especially demanded in large halls in which energy and water consumption are crucial for maintenance costs. In this article, energy analysis of a DHW preparation system for workers’ hygienic purposes in a industrial hall was performed. The DHW preparation system consisted of three sources: a flue gases heat exchanger as the waste heat source, solar collectors as the renewable heat source and a gas boiler as the conventional source. In the analysis, data of a variable-temperature supply of water and hourly water consumption data from the measurements in the industrial hall, located in Poland, were applied. The results for all of the 8760 h of one year were examined. The analysis outcomes show that implementation of non-conventional sources can supply 81.4% of energy needed for DHW preparation, avoiding a lot of running costs; just 18.6% of heat demand had to be obtained from a gas boiler. The analysis also confirms that the system may operate correctly when the appropriate device size is applied, along with a proper control strategy that avoids overheating water and uses alternative sources.

Heating large halls consumes a significant amount of energy. Gas radiant heaters are a common solution in hall spaces and are considered to be more energy efficient than convection heating systems. It can be also apply waste heat recovery (WHR) from flue gases of radiant heaters. This paper deals with ceramic and tube gas radiant heaters and state-of-the-art WHR technologies and systems applied in flue gases system of gas radiant heaters. The research analyses the heat exchanger type, exhaust temperature, intermediary utilities (water/air), number of additional devices and recovery system placement, which enables the overall description of the devices efficiency, exhaust temperature range, benefits and limitations of the WHR systems. This is followed by an assessment of the economic aspect and guidelines for future research in this field. The key conclusions is that the WHR system development requires more research, essentially into ceramic gas heaters and technology with water as a medium, more energy and profitability analyses of energy gain and additional energy consumption associated with WHR’s operation plus significant information dissemination and financial support on WHR examination.

People's subjective response to any thermal environment is commonly investigated by using rating scales describing the degree of thermal sensation, comfort, and acceptability. Subsequent analyses of results collected in this way rely on the assumption that specific distances between verbal anchors placed on the scale exist and that relationships between verbal anchors from different dimensions that are assessed (e.g. thermal sensation and comfort) do not change. Another inherent assumption is that such scales are independent of the context in which they are used (climate zone, season, etc.). Despite their use worldwide, there is indication that contextual differences influence the way the scales are perceived and therefore question the reliability of the scales’ interpretation. To address this issue, a large international collaborative questionnaire study was conducted in 26 countries, using 21 different languages, which led to a dataset of 8225 questionnaires. Results, analysed by means of robust statistical techniques, revealed that only a subset of the responses are in accordance with the mentioned assumptions. Significant differences appeared between groups of participants in their perception of the scales, both in relation to distances of the anchors and relationships between scales. It was also found that respondents’ interpretations of scales changed with contextual factors, such as climate, season, and language. These findings highlight the need to carefully consider context-dependent factors in interpreting and reporting results from thermal comfort studies or post-occupancy evaluations, as well as to revisit the use of rating scales and the analysis methods used in thermal comfort studies to improve their reliability.

Thermal discomfort is one of the main triggers for occupants’ interactions with components of the built environment such as adjustments of thermostats and/or opening windows and strongly related to the energy use in buildings. Understanding causes for thermal (dis-)comfort is crucial for design and operation of any type of building. The assessment of human thermal perception through rating scales, for example in post-occupancy studies, has been applied for several decades; however, long-existing assumptions related to these rating scales had been questioned by several researchers. The aim of this study was to gain deeper knowledge on contextual influences on the interpretation of thermal perception scales and their verbal anchors by survey participants. A questionnaire was designed and consequently applied in 21 language versions. These surveys were conducted in 57 cities in 30 countries resulting in a dataset containing responses from 8225 participants. The database offers potential for further analysis in the areas of building design and operation, psycho-physical relationships between human perception and the built environment, and linguistic analyses.

Heating of large-cubage buildings accounts for significant share of energy consumption. The radiant heating system using gas heaters is a common solution for large-cubage halls and is considered to be energy efficient. There is a possibility of additional heat energy recovery from the flue gases of gas radiant heaters because new solutions were introduced to the market. Furthermore heat recovery consists the most promising solution and develop during the recent years rapidly. On the other hand, few works have been dedicated to heat recovery from exhaust gas but none of them consider exhaust gas from radiant heaters. Exhaust gas temperature depends on the type and efficiency of the gas heater. The selection of both the type of radiant heaters and the heat recovery system requires many factors to be taken into account. This study consider possibilities for application of different heat exchangers in exhaust gases system of gas radiant heaters. The authors propose to classify exhaust gas heat recovery systems in dependence on intermediary medium: water/air, gas heaters type: ceramic/tube and number (single/group) and their mounting location.

The constant demand for domestic hot water (DHW) creates great opportunity for drain water heat recovery (DWHR) systems in hospitals, so there is an enormous potential to reduce energy consumption in accordance to the EU environmental policy. This paper aims to assess the energy saving from greywater in hospitals. The energy analysis considered the type, constructions, efficiency of the proposed four types of heat exchangers (HEX). The measured data from two Polish hospitals was elaborated and calculated for two supply cold water temperatures: constant and variable. Results ensure that implementation of HEX type GFX allows to save up 30% of the energy demand.

Water consumption in hall buildings is substantial and characterised by variability over the time: yearly, seasonality, monthly, weekly, daily, hourly and second. Both, water consumption and their irregularity, influence on many processes and technical issues. Purposes for which water is consumed are various. Beyond the technological processes, one of the most water-intensive demand is need for water for hygienic and sanitary purposes, especially in production buildings with high degree of soiling work. The paper presents the study of hot water (DHW) consumption and its profile for sanitary and hygienic purposes in two production halls. The halls vary in the degree of soiling work, sanitary equipment and numbers of employees. The aim of this article is to define DHW consumption profiles and hourly water-consumption irregularity coefficient applicable in design process of hot water preparation for hygienic purposes in production buildings. The average daily hot water consumption varies significantly and amounts 7 or 16 m3 respectively to both halls. Despite the discrepancy of sanitary equipment and number of workers the hourly water-consumption irregularity coefficients for both halls are in the similar range, about 2, and daily domestic hot water profiles present typically three main consumption peaks that occur at the end of work shifts.

The article presents different aspects of application of copper pipes in water supply system, which have importance on properly work of installation and people health safety. The article analyses the water flow velocity criteria and their influence on the operation of the installation. It is particularly dangerous for copper pipes to exceed the permissible water flow velocity, as this results in corrosive processes. It is also not recommended that the flow velocity be too low, as it affects the development of biofilm and multiplication of bacteria.

The actual volume of water consumption in the various industrial halls is very diverse. Many factors have an impact on that value, depending on the demand for: domestic, fire-fighting, technologically specific target and other purposes. The demand for domestic water in the production hall is primarily due to the use of showers, wash basins and flush toilets. Workplaces should be appropriately equipped with hygienic and sanitary facilities, depending on its degree of soiling, type of work and gender. The water flow is relevant for dimensioning the water supply system including the diameter selection of the water pipes. Criterion for selection of the diameter is the flow velocity of the water which varies depending on the manufacturer’s guidelines, the material used and the law. The article analyses the dynamics of load pattern of hot water in industrial halls. The methods of flow calculation in production halls based on an analysis of patterns available in literature and the water flow velocity criteria is discussed. The results of the research of the dynamics of water load pattern in a production hall located in Wroclaw is presented and discussed.

The systems using solar energy, popular in Poland, can be used to supply hot water for the installation used by employees of industrial halls. In manufacturing plants, employing a large number of people, the demand for hot water is practically constant throughout the year and is characterized by periodic use at the end of each work shift. Dynamics of the hot water consumption depends on the number of shifts as well as working days and holidays. Additionally the maximum hot tap water demand occurs in the whole period of installation operation. In polish climatic conditions the solar collectors’ systems have the largest capacity in the summer, while in winter they need to be assisted. Beside that the supply of renewable energy is uneven and depends on weather conditions. In the paper the one-hour step analysis concerning the dependence of the load pattern of the hot tap water preparation system on the energy yield from solar collectors had been performed.

Radiant ceiling panels can be used in large-volume halls, e.g. vehicle repair shops and markets, to heat the entire or specific zones of the enclosed space. The system with radiant panels may be of small water capacity when just one or several units are installed over selected zones to provide additional heating. Depending on dimensions of radiant ceiling panel, its mounting mode and the temperature of its feeding medium, various thermal conditions are created under such panel. Thermal effects are also affected by the mode of thermal or cooling power control and dynamics of such control for an individual radiant panel or a set of panels. The dynamics of attainable radiant ceiling panel capacity was investigated and used as the grounds to determine general requirements for time-domain automatic control programs and those for operation of the controllers. The results presented from the examinations carried out for water radiators are not intended to delineate the requirements for all automatic control loops for water radiators; they are aimed at attracting attention to issues to be considered when preparing the algorithm of automatic control in particular situations.
