“…Italy (followed by Spain, UK and China) is the country that has generated most papers related to the energy efficiency in listed building research, e.g. (Mauro et al, 2015;Bonomo & De Berardinis, 2014;De Berardinis et al, 2014;Ascione et al, 2013). As the statistic shows in Martinez's research, publications of listed buildings from Sweden are few, e.g.…”

In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO 2 emissions. Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. The increased energy use and threat from CO 2 emissions of the building sector create a need for energy efficiency. The important role that renovation of residential buildings will play in reducing the total energy used by the Swedish building sector as well as in reducing primary energy use and CO 2 emissions on both the national and global levels has been the impetus for the studies included in this thesis.The aim of the current research is to develop a methodology from a system perspective which can be used to analyze the energy use, optimal life cycle cost (LCC), energy efficiency measure (EEM) package, indoor environment, CO 2 emissions, and primary energy use of a building or a community during major renovation. The developed methodology accomplished at three different levels, i.e. building level, cluster level and district level. The methodology considers both energy efficiency and economic viability during building renovation and will also play an important role in overall urban planning. The studied buildings include both nonlisted and listed residential buildings and the tools used include building energy simulation (BES), survey, technical measurements, LCC optimization and building categorization.The results show that the combination of BES, technical measurements and surveys provides a holistic approach for evaluation of energy use and indoor environment of the studied residential buildings. The results from the current study also show that the 2020 energy target, i.e., reduction of energy use by 20 %, for the building sector can be achieved by all the studied building types and that the total LCC of these buildings are below the cost-optimal point. In comparison, the 2050 energy target, i.e., reduction of energy use by 50 %, for the building sector may be achieved by the non-listed buildings, but when the constraints relevant to listed buildings are added the cost-optimality changes as some EEMs in direct conflict with the building's heritage value may not be implemented.The investigation of primary energy use and CO 2 emissions by the residential buildings show that the higher the energy saving, the lower the primary energy use becomes, and vice versa. With the same energy saving, the heating system with higher primary energy factor results in higher primary energy use. From a CO 2 emissions point of view, EEM packages proposed to help buildings connected to a CHP based district heating system, to reduce the energy use or LCC are not consistently effective. Since these EEM packages will reduce district heating demand, the electricity produced in the CHP plant will also decrease. When the biomass is considered a limited resource, measures such as investm...

“…Modern technological capabilities of manufacturers of translucent structures allow the mass production of window blocks with the thermal resistance of 1.0 m 2 0 С/W and higher, which exceeds the thermal resistance of external brick walls with a thickness of 770 mm (3 bricks). When they are used, the heat loss of buildings through the outer enclosure in the winter period of operation differs from traditional significantly [7][8][9][10][11][12][13][14][15]. In this case, from the point of view of providing thermal protection, the windows will not be the most vulnerable part of the outer shell of the building.…”

Abstract. The work presents the prerequisites to replace the window units in the historical buildings (primarily increased energy efficiency standards of buildings and significantly changed performance requirements of window units). The analysis of possible replacement options (full/partial) of window units of the historical buildings is done according to their architectural and historical values. A review is made of the existing technological capabilities of modern window systems and translucent filling (double-glazed windows), as well as the most common solutions used in practice. The issue of providing the temperature-humidity conditions of the nodes of adjunctions of the window blocks to the openings of the external walls in the winter operating conditions is considered. For this purpose, a numerical simulation of the temperature fields of the junction points is made for various structural embodiments of window frames. It is established that in the case of a full replacement of window blocks and maintaining the existing structure of external walls (the calculation is made using the example of the most common external wall for Central Russia -a brick wall 770 mm thick), condensation may form on the inner surface of window slopes. Different options are suggested for window blocks installation, which ensure the fulfillment of sanitary and hygienic requirements. Further directions for the research on the use of modern types of translucent structures in the historical buildings are outlined.

Scientific community and government institutions have acknowledged energyretrofitting solutions for historic buildings as strategic within the EU "20-20-20" target, provided that they should be developed from the assessment of the local environment. Geographic-climatic conditions of site, historic-morphological development of settlement, typological-architectural configuration of buildings and construction-technical characteristics of components feature that environment, which shapes the domain, where expected performances of requalification products and processes might be defined. The final goal is the challenging and desirable balance among conservation of original material and formal identity, enhancement of present and potential relationships between indoor space and outdoor environment, technological improvement of construction systems. The paper is going to discuss an assessment methodology, applied to the historic sea towns in the Province of Bari, South Italy. Specifically, the methodology focuses on the investigation of all the above-mentioned aspects, also by means of analytical simulations, onsite measurements and thematic maps, in order to develop reliable energy models for historic buildings. The models should support the analysis of the relationships between performances of building sub-systems and efficiency of building system, always taking into account the transformation boundaries of the envelope, towards efficient, compatible and convenient energy-retrofitting solutions.
