The research topic contributes to the possibilities of energy performance modernization in ‘Squirell Garden’ Nursery School in Csurgó, Hungary. The building bears a special importance for my family and for me, since my mother works there, and I used to attend it as a child. The aim is to achieve an improvement that fulfills the infrastructural requirements set for modern, 21st century nursery schools, that improves the comfort level of children and teachers in the nursery school, makes the maintenance of the facilities more economical and in conformity with regulations, and enhances the quality of education as well as the visual appearance of the building. The target group of the modernization consists of the nursery-school children, parents, nursery-school teachers and nannies, the local government of Csurgó. The study and the calculations implemented are giving a general idea about modernization possibilities of a vintage, since decades unrefurbished kindergarten building, focusing on comfort and low energy consumption.

Abstract

The yurt is one of the ancient living units for the nomadic cultural country. The yurt is a nomadic vernacular architecture, which has been developed for 3000 years. There are 31 counties using the yurt, out of which 13 of them use their traditional yurt around the world. Basically, the yurt was used as residential housings and today, also to some extent, for commercial and touristic purposes under different climates. Analyzing existing literature, as well as scientific publications it is apparent that besides architectural and structural topics, there is no existing investigation or published paper about building physics analysis of these buildings. Current research aims to create a database about energy and climate comfort qualities of traditional yurts using dynamic calculation tools. As a result, to intend to learn from the traditional yurt technology and to develop a completely new and modern building prototype based on the yurt-experiments in next step of research. Firstly, finding optimal solutions for a contemporary yurt-building' should be applied under Mongolian climate conditions, since this form of housing is still used in this country, and, in addition, the comfort and energy performance of the yurts were surprisingly satisfactory under extreme weather conditions, by temperature differences between summer and winter of approx. 80 K.

This paper has the main focus in energy consumption by the residential sector in city of Prishtina. Considering the fact that the energy production in Kosovo is not sufficient in relation with the everyday demand and at the same time the growth of the energy demand based on different resources is evident, a detailed analysis and identification of the energy performance of this sector is inevitable. One of the main components that cause the energy demand in residential sector is the heating energy demand. The energy resource and heating systems used by the residential sector in city of Prishtina are diverse.

This paper elaborates and identifies the number of residential buildings, number of dwellings, building typologies, heating energy resources, heating systems used by the dwellings and the energy demand for heating energy, by using quantitative methodology. Based on the results achieved by the research, future detailed analysis is possible to identify other components, which affect the heating energy demand by the residential sector. These first results can be used as a basis of the first district scaled energy modeling of the city of Pristhina. By applying the energy management method, developed by Prof. Gerhard Hausladen and his research group at the TU München, a first modeling step will be absolved. After analysis of the current state of the investigated districts, future concepts will be made increasing efficiency and sustainability.

Thermal bridging caused by exposed concrete balcony slab is a major source of heat loss through energy efficient building envelopes. Moreover, thermal bridging can also create moisture management and indoor comfort challenges. Numerous investigations have been carried out to reduce heat transmittance through exterior building envelopes and minimize the energy use in buildings. The most effective way to minimize heat transmittance of exposed concrete balcony slabs is to thermally separate the exterior structure from the interior structure using thermal breaks. To enhance thermal separation, this paper investigates the effects of replacing high conductive materials such as reinforced concrete or structural steel with a multilayer composition of high-performance hybrid insulating systems. Reinforcing bars, such as fiber reinforced plastics (FRPs), having lower thermal conductivity than steel are used to connect interior to exterior and transfer loads. Numerical simulation tool THERM is used to study the effects of thermal breaks on energy performance of the concrete slab balcony joints. Simulation results indicate significant thermal performance improvement while high-performance hybrid insulating systems were used for exposed concrete balcony slab constructions, compared to traditional insulating systems used in similar constructions
