This paper presents a literature review about aerogel-based products for building, focusing on the plasters used within the architectural restoration sector. Aerogel has entered the construction field in the last two decades as a component of many insulation products, due to its high thermal performance. Aerogel-based plasters allow the matching of high thermal performance and limited thickness. This makes them suitable when retrofitting an existing building and also when restoring a heritage building. We analyze the results of recent research, focusing on the most commonly used methods for assessing the thermal performances and durability of aerogel-based plasters. As a result of this review, we propose a guideline for manufacturing samples destined for laboratory tests.

Abstract The Swedish National Research programme for Energy Efficiency in historic buildings was initiated in 2006 by the Swedish Energy Agency. This article gives an overview of the programme: objectives, projects and the general results of the programme. The research programme aims to develop knowledge, methods and technical solutions that contribute to energy efficiency in historically valuable buildings without destroying or damaging the historical value of the buildings, including decoration, furnishings, interiors or equipment. The programme is not limited to listed and monumental buildings but covers a wider range of historic buildings that account for a large part of the energy use in the building sector. For one and two-family houses, around 25 % of the energy use is associated with buildings built before 1945. The same number for multifamily houses is around 15 %. The programme is currently in its third consecutive four-year-stage. Previous four-year-stages were completed in 2010 and 2014. Over time, the scope of the programme and the projects have developed from mainly dealing with indoor climate control in monumental buildings towards addressing more general issues in the much larger stock of non-listed buildings. Technical research, based on quantitative analysis, dominate throughout all three stages, however most projects have had interdisciplinary components. The results from the programme have been presented in 31 journal papers, 67 conference papers, five books and five PhD theses. The projects have also contributed to CEN standards and resulted in a number of Bachelors and Master’s theses. An equally important long-term effect of the programme is that the number of Swedish researchers in the field have increased from practically none in 2007 to 18 senior researchers and twelve PhD students from ten universities in 2014. The research programme on Energy Efficiency in historic buildings is unique in an international context. Hopefully it can serve as an example for other countries on how to address an important interdisciplinary research challenge.

The 19Th Century

From the 19th century onwards, glass has been used intensively in buildings. During the design process, the importance of aesthetics is very common for architects in general. The application of glass walls as part of the building’s structure has given flexibility in design together with transparency as well as aesthetics. Structural glass systems have been used in different building types for example office, residential, educational, commercial, transportation, cultural … Beyond the high - rise and high - tech buildings, structural glass systems have been applied also to historic buildings during their conservation process. The adaption of the structural glass system and the opportunity to reuse the existing building are other important aspects to be discussed. In this article, the literature review will be formed with a brief explanation of transparency in contemporary architecture, structural glass systems focusing on ‘suspended glass systems with pre-stressed cable trusses’ (SGSPCT) which has three application methods; 1) between floor systems 2) independent body systems 3) distance bridging systems and the reusability of existing buildings. The ‘between floor system’ which is commonly used as a contemporary solution technique for historic buildings together with its effects, will also be analysed with the help of a case study, Esma Sultan Mansion. This historic building’s present glass structure will be studied to create an alternative proposal less dependent to the existing building. Another case study will be the Ballapais Abbey. Part of this gothic building (the common room) that has collapsed in the past will be analysed. An independent glass structured annex designed with SGSPCT will be proposed giving joint details of the adaptation to the existing building. This case of study is a literature analysis based on books, internet resources, articles and architectural drawings, like plans, sections and details related to the buildings. Both case studies will be proposing an alternative glass structured annex that is focusing on gained transparency and reusability in respect to the existing historic building.

This paper deals with the hygric characterization of early 20th century machine-made clay bricks, representative of great number of historical buildings in north-eastern Poland. Heritage buildings have a high potential for adaptive reuse, which is strictly connected with an urge for knowledge about the properties of these existing building envelopes. To better understand the hygric behavior of historic buildings, various experimental laboratory tests, including density, water absorption, compressive strength and freeze-thaw resistance, were conducted. In order to assess the microstructural characteristics of the tested bricks, mercury intrusion porosimetry (MIP) and X-ray micro-computed tomography (micro-CT) tests were performed. These tests were conducted on clay bricks from historic buildings, as well as on those that are currently being produced, in order to identify the relationship between the materials used in the past and the replacements produced presently. This paper addresses the lack of systematic application of existing standards for evaluating the state of the conservation of historic bricks and for establishing the specifications for replacement bricks. The results of conducted study and further research will be the basis for creating a historic materials database. It would be a useful tool for selecting bricks that correspond with the historically used materials and help to maintain homogenous structure of the restored buildings.

Larsen, Nansen, Grönvold, Wolstrup and Henriksen (1997) have previously reviewed the prospects of control of equine nematodes by using fungal cultures. Since then more investigations have been implemented and actualized. Field trials and laboratory tests have been reported with new perspectives and increasing number of animals in trials. The aim of this new review of literature is to add new knowledge to those questions that remained open in the 1990s. In particular, on the perspective of veterinary practitioner and sustainable use of deworming practices it is important to know those directions which should be followed.

Wind Comfort

There is a distinct lack of building design literature specific to the Central Asian region. This perhaps, could be one of reasons for the only slight improvement of new building designs and construction. One does observe the highly glazed buildings are a particularly popular feature here in Astana, as like anywhere else in the world. However, excessively glazed surfaces combined with the weather extremes leads to adverse internal conditions and skyrocketing energy bills. The work presented in this paper is a part of continuing efforts to identify analyze and promote the design of ‘low energy, green and sustainable buildings with special reference to the Kazakhstan locality. In the present context, low energy buildings’ refers to buildings inherently low energy consuming by careful passive design, utilizing intelligent building technologies to automate building services and minimize wastage of energy and by incorporation of renewable technologies for its energy supply. Demonstration of improved environmental conditions and impact on energy savings will be outlined through a cause study incorporating application of passive design approach and detailed computational fluid dynamics (CFD) analysis for an existing building complex. The results indicated that there is a considerable influence of passive design and orientation on energy efficiency, wind comfort and safety.
