Abstract Building standards for energy effectiveness are increasing constantly and the market follows these changes by constructing new buildings in accordance with standards and refurbishment of the existing housing stock. Comprehensive trends in European construction market show tremendous increase in building retrofit works. It can be predicted that after the end of this decade, more than half of the construction works in European cities will be taking place in existing buildings, pushing the construction of new buildings to a less important role. Such a growth in building refurbishment works is creating a demand for suitable materials, retrofitting techniques and research. The differences between refurbishment of new-build projects and historical or valuable buildings are insufficiently recognized - mostly the buildings without further cultural preservation requirements are studied. This article covers the theme of refurbishment measures in historical buildings - the specific measures like inside insulation which are allowed due to the valuable façade or other heritage preservation requirements. An overview of other innovative methods for energy saving in existing buildings and their potential is given.

While, in practice, the rehabilitation of prefabricated housing estates has mostly focused on the buildings, a comprehensive concept, which is able to revalorise this problematic housing stock has become increasingly relevant. The specific, holistic proposal of the revalorisation demands an interdisciplinary approach, based on urban planning principles of SUN (sustainable urban neighbourhoods), that can reconceptualise housing units on the different scales as plot, patch and part of a city or town. To find proper methodology, this paper attempts to adopt an approved evaluation tool used in the field of property development. Property development strongly adheres to various certification systems. These apply not only to buildings, but on the urban scale, neighbourhoods can also achieve good qualification in systems like LEED Neighbourhood. This study argues that the requirements of LEED Neighbourhood can be adequately applied in the case of existing housing estates; as a result of which, they could become less isolated and could be more easily integrated into the neighbouring urban network as sustainable parts of cities and towns.

Adequate Data

Serbia’s Law on Planning and Building has imposed the topics of energy efficiency in building sector, requiring adequate policy making and providing a starting point for improvement of the current situation in this field. Considering the fact that there are more than 3.200.000 housing units without any statistical classification a need arose for establishing a national building typology as a starting point for further decision making and appropriate activities definition regarding the existing housing stock. After joining EU TABULA (Typology Approach for Building Stock Energy Assessment) project, methodologies and approaches of the European countries have been analysed providing a common experience, at the same illustrating a need for identification and classification of local characteristics. In order to obtain adequate data a comprehensive survey has been conducted, providing a starting point for creation of typology. The National Typology has identified typical “model” buildings and defined the levels of improvement ranging from standard (according to the current law) to the low-energy level. The paper explains the methodology, procedures and local characteristics of the process and gives an insight in the activity describing the problems and potentials of the approach.

The article analyzes domestic and international experience in the field of energy efficiency and energy security. Thus, it was important to adopt the Law of Ukraine "On the Energy Efficiency of Buildings", which introduced mandatory certification of buildings by energy consumption classes. The study of sources on the issues of effective energy consumption showed that issues related to improving the energy efficiency of buildings and structures are acquiring special relevance; the use of foreign models to improve the energy efficiency of the housing stock. Specific organizational and economic measures are highlighted that will help improve the energy efficiency of the national economy. The Swedish experience of using a modern cost model for the full period of operation ("General Concept") is studied, which aims to assess the economic results of investments in measures to improve the energy efficiency of the housing stock. The main principles of the modern cost model of the full operation period and the criteria for determining the number of necessary energy efficiency measures are considered. Analyzed "hard" (physical condition of the building) and "soft" (user behavior) measures that provide for the integrated energy efficiency of the building. The stages of the analysis according to the cost model of the full operation period are considered. The typical for Sweden ranges of the duration of energy efficient measures and the requirements for the internal rate of return, which depends on the general economic situation in the country and the terms of the loan, have been investigated.  Based on the results of the energy audit of the ten-story building selected for the study and taking into account the experience of Sweden, a number of measures to improve energy efficiency are proposed and a calculation is given to ensure the energy efficiency of a residential building in Ukraine. Based on the results obtained, it can be concluded that there is a positive trend in this implementation. With the integrated use of all measures that will even allow you to save more, you can significantly improve the energy efficiency of the existing housing stock in Ukraine.

Abstract Following the increasing necessity of quantitative measures for the impact of natural catastrophes, this paper proposes a new technique for a probabilistic assessment of seismic risk by using publicly available data on the earthquakes that have occurred in Italy. We implement an insurance-oriented methodology to produce a new map of the seismic risk and to evaluate, under various hypotheses, the costs of insuring all the Italian housing units against it. The model is compared with two main privately developed models, well known in the reinsurance industry, providing fairly similar results.

Purpose The purpose of this paper is to analyze energy performance of the multi-storey buildings built in the city of Tlemcen between 1872 and 2016. Design/methodology/approach A diagnosis based on a bottom-up methodology, using statistical techniques and engineering, has been developed and applied. To do this, demand condition analysis was conducted using a data collection survey on a sample of 100 case studies. Physical characteristics of the buildings have been determined through the archetype by period. This serves to define the strengths and weaknesses of buildings as energy consumers. Findings The obtained results showed that dwellings built between 1872 and 1920 offer better energy performance with a consumption index close to 130kWh/m2/year and this compared to the five periods considered. For dwellings built between 1974 and 1989, energy consumption is higher with an index approaching 300kWh/m2/year, thus qualifying the buildings of this period as energy intensive. Originality/value A database is established to collect physical information on the existing housing stock and thus allow their classification vis-à-vis of the energy label. This study is part of a research project aimed at evaluating and determining optimal measures for energy rehabilitation of multi-family buildings in Tlemcen. Thermal rehabilitation solutions are proposed using thermal simulations, in the following studies, to improve thermal performance of existing buildings. This study constitutes the first step of a roadmap applicable to other cities constituting climatic zones in Algeria. This helps to enrich the Algerian thermal regulation in thermal rehabilitation of existing residential buildings and conception of new ones, in urban areas with a similar climate.

The Relationship

Substandard housing is a major public health issue in New Zealand. Approximately, two-thirds of the housing stock is uninsulated and many homes are inadequately heated, with an average indoor temperature of 14.5°C. Cold, damp, and mouldy housing results in poor health; each year, respiratory hospital admissions are 74% higher during winter, and excess winter mortality is 20% higher than other seasons. The relationship between injury and housing conditions is also well established. Each year, 500,000 New Zealanders suffer falls requiring medical treatment in their homes. As a step towards improving the quality of existing housing, an evidence-based warrant of fitness has been developed. This article outlines the evidence base to each criterion in the warrant of fitness. We conclude that introducing and properly enforcing a housing warrant of fitness will ensure that basic minimum standards are met, which could mitigate the disease burdens and injuries associated with, or caused, by poorer quality housing. In addition, there are potential fiscal and economic advantages of the scheme, including reduced hospitalisations and increased productivity.

Over the last decade, private rental sectors have been in rapid ascendance across developed societies, especially in economically liberal, English-speaking contexts. The Netherlands, and Amsterdam in particular, has also more recently experienced the reversal of a century-long decline in private renting. More unusually, the expansion of private renting in Amsterdam has been explicitly promoted by the municipal and national government, and in cooperation with social housing providers, in response to decreasing accessibility to, and affordability of, social rental and owner-occupied housing. This paper explores how and why this state-initiated revival has come about, highlighting how new growth in rent-liberalized private renting is a partial outcome of the restructuring of the urban housing market around owner occupation since the 1990s. More critically, our analysis asserts that restructuring of Amsterdam’s housing stock can be conceptualized as regulated marketization. Market forces are not being simply unleashed, but given more leeway in some regards and matched by new regulations. We also demonstrate various tensions present in this process of regulated marketization; between national and local politics, between existing housing and new construction, and between policies implemented in different time periods.
