This paper presents a home automation plant, consisting of a distributed heating system. It is a system implemented on a residential home, however it could be extended and used for other buildings as well. The paper presents the distributed heating system’s structure, extended from a classical heating system, and the authors also describe the equipment used for the designing and implementation of such a system. The way the system works is depicted, and the authors enfold all the benefits of using such a distributed heating system, such as, increasing the user’s thermal comfort on different living areas and reducing the costs of thermal heating.

In an effort to reduce the operational cost of their dwellings, occupants may even have to sacrifice their indoor thermal comfort conditions. Following the economic recession in Greece over recent years, homeowners have been forced to adapt their practices by shortening heating hours, lowering the indoor thermostat settings, isolating spaces that are not heated or even turning off their central heating system and using alternative local heating systems. This paper presents the results from over 100 occupant surveys using questionnaires and walk-through energy audits in Hellenic households that documented how occupants operated the heating systems in their dwellings and the resulting indoor thermal comfort conditions and actual energy use. The results indicate that the perceived winter thermal comfort conditions were satisfactory in only half of the dwellings, since the actual operating space heating periods averaged only 5 h (compared with the assumed 18 h in standard conditions), while less than half heated their entire dwellings and only a fifth maintained an indoor setpoint temperature of 20 °C, corresponding to standard comfort conditions. Mainstream energy conservation measures include system maintenance, switching to more efficient systems, reducing heat losses and installing controls. This information is then used to derive empirical adaptation factors for bridging the gap between the calculated and actual energy use, making more realistic estimates of the expected energy savings following building renovations, setting prudent targets for energy efficiency and developing effective plans toward a decarbonized building stock.

This article addresses questions of elucidation in talk-in-interaction. How do social actors give accounts of what they are doing? To what degree do actors sustain a taken-for-granted level of reasoning? The analysis is based upon naturally occurring data consisting of a corpus of audio recorded case conferences at various geriatric wards in Danish hospitals. The article elaborates one of the important insights of Harold Garfinkel regarding the relationship between discourse and social interaction: as a general characteristic, people tend to treat their fellow interlocutors’ conversational contributions as adequate for-all-practical-purposes. Specifically, the article investigates how Danish municipal representatives account for their decisions about whether or not senior citizens are to be referred to residential homes. This practice, I demonstrate, is characterized by non-explicitness with regards to rules and regulations. Instead, municipal representatives make use of developmental discourse: a worsened condition is used to justify a referral to a residential home. On the other hand, an improved condition is used to justify that an elderly citizen is not referred to a residential home.

As sleep is unconscious, the traditional definition of thermal comfort with conscious judgment does not apply. In this thesis sleep thermal comfort is defined as the thermal condition which enables sleep to most efficiently rejuvenate the body and mind. A comfort model was developed to stimulate the respective thermal environment required to achieve the desired body thermal conditions and a new infrared sphere method was developed to measure mean radiant temperature. Existing heating conditions according to building code conditions during sleeping hours was calculated to likely overheat a sleeping person and allowed energy saving potential by reducing nighttime heating set points. Experimenting with existing radiantly and forced air heated residential buildings, it was confirmed that thermal environment was too hot for comfortable sleep and that the infrared sphere method shows promise. With the site data, potential energy savings were calculated and around 10% of energy consumption reduction may be achieved during peak heating.

Abstract This paper evaluates a static heating system from a church. They are presented in almost every church. Temperature distribution in the church is done in 2d plane. The simulation is presented on a particular example, the Dormition of the Mother of God Church from Jassy, Romania. The heating system had been simulated in FLUENT and the consequences over the interior climate in the church are showed. An important issue is the impact of this system over the artwork, the church being rise in XVIII century.

Motivated by the rapid spread of the novel pandemic disease (COVID-19) that swept the most countries in the world, a new radiation heating system consists of wall radiator panel system connected to a reversible geothermal heat pump (GHP) coupled with horizontal ground heat exchanger (HGHX) was proposed as fast and permanent solution to the risks of the dispersion of airborne infectious diseases in air-conditioned enclosed spaces. An experimental system was installed and tested in the laboratory of thermal process of Research and Technology Center of Energy (CRTEn), Tunisia, in order to achieve the two main goals of this work: developing a new radiation heating system with quick and inexpensive implementation while ensuring high efficiency and environment-friendly performance for the entire system. The results obtained show that it is feasible to use the novel RPHs as heat rejecter of the horizontal ground source heat pump system (HGSHPs) for heating buildings with limited surface land areas epically those located in the Mediterranean regions such as Tunisia, the average performance coefficients of the geothermal heat pump COPhp and the overall system COPsys are found to be 6.3 and 3, respectively. The thermal comfort analysis indicates that there is only a small vertical temperature fluctuation in the test room that would not produce any negative effect on thermal comfort.

AbstractThis paper reports on the analysis of data collected in a study looking at older people moving into nursing and residential homes. Using life history methodology, participants are interviewed before and after arrival at homes in order to determine the process of adapting to their new environment. Initial data analysis indicates that this process requires extensive social activity on the part of the new resident, involving negotiation of complex social conventions. The discussion focuses on two themes which have been identified from the data: constructing familiarity whereby participants use sometimes tenuous knowledge of people and places to make the home seem less strange, and managing the self, whereby familiarity is used as a means of permitting social conversation to take place without leaving residents open to the dangers of being intrusive. These two themes have relevance for the way in which new residents can be introduced to homes, and the way in which the social skills of older people are viewed.

ABSTRACTThe paper reports on a study carried out in 1990 for the Department of Health looking at the development of local authority multi-purpose residential homes for elderly people in England and Wales. A national survey showed that one in five public sector residential homes for elderly people would soon be multi-purpose. This proportion could be expected to increase in the 1990S. Many of these homes had become the centre for virtually all the community support services for elderly people in the neighbourhood. Despite some obvious management advantages in making use of residential home facilities for older people in the community, there have to be serious reservations about a multi-purpose model. Case studies in six multi-purpose homes suggest that residents themselves may gain little or nothing from this arrangement. Few interact with elderly people from the neighbourhood in the day centre. So much activity on the premises meant that invasions of residents' privacy and space were common.
