Purpose – The purpose of this paper is to discuss methodological guidelines and operation protocols for the assessment of historic buildings by radar techniques, as decision-making support within integrated investigation programs, where documentary records, direct survey and onsite measurements address accurate and effective diagnosis. Design/methodology/approach – Radar methodologies and procedures are planned to support the pre-diagnosis hypotheses, based on preliminary information from historical sources, as well as from direct survey of geometry, materials, construction techniques and decay patterns. Thus, they are applied, in terms of acquisition and elaboration systems, taking into account the testing targets and surrounding conditions. Finally, they are correlated with complementary destructive and non-destructive techniques for data interpretation and validation. Findings – The general approach is developed for some representative case studies, in order to point out the potentialities of radar tec...

Purpose – The purpose of this paper is to present a case study of cracks on external thermal insulation composite systems (ETICS) along the thermal insulation joints and the information available on the building pathology catalogue – PATORREB. The aim is to establish the methodology to study the cause of the pathology observed on a building which is located on the interior of Portugal based on in situ probing together with the analysis of hygrothermal and mechanical behaviour. Design/methodology/approach – An in situ analysis was performed to assess the causes. The hygrothermal dynamic behaviour of the wall was analysed with a numerical simulation advanced tool considering the climatic conditions, the characteristics of the thermal insulation plates as well as the support and finishing layer properties. Moreover, a qualitatively analysis of the mechanical behaviour, based on the bonding process, thermal insulation and exterior rendering properties was performed. Findings – It was concluded that the insulation properties – thermal expansion coefficient and stiffness, the thermal expansion coefficient of the exterior rendering, together with adverse climatic conditions were critical for the appearance of cracks along the plate joints, particularly with spot bonding. The expansion and retraction stresses and the restrained movements of the components can result in bending moments, especially when the insulation material has a high stiffness value, which will create the crack on the rendering system. Originality/value – A combination between a hygrothermal and mechanical analysis of an ETICS pathology concerning the appearance of cracks with a subsequent integration into a building pathology catalogue.

Purpose – Building owners are encouraged to reduce the energy consumption both in order to contribute to national energy saving goals and to reduce the costs of heating and operation of buildings. However, it is important to pursue the most optimal strategy to achieve cost-effective energy use while maintaining other values. Building managers often do not have the time or expertise to make a proper evaluation of the available options, hence there is a need for practical methodologies for evaluation of renovation alternatives. The paper aims to discuss these issues. Design/methodology/approach – Renobuild, a systematic approach for evaluating renovation alternatives based on sustainability criteria are under development. It aims to compare renovation alternatives from an environmental, economic and social perspective. To verify the methodology it has been used to evaluate different renovation alternatives for a multi-family apartment building in Sweden. Findings – The study showed that building managers ar...

Purpose – Maintaining a comfortable physical environment in the workplace is claimed to be vital as it will create a “healthier” building with optimum environmental conditions, which enable employees to be healthier and have a lower absenteeism rate, and hence be more productive. Thus, the purpose of this paper is to deal with the importance of physical environment comfort in the office workplace. Evaluation was made of the office workers’ performance that is mainly affected by levels of comfort in the office. Design/methodology/approach – Three selected case studies were evaluated based on aspects of employees’ comfort, perceived health and absenteeism rate, by considering the elements of physical comfort that consist of room temperature, relative humidity and luminance level. The selected case studies were the Department of Development and Estate Maintenance of three research universities in Malaysia. Field studies were carried out using hygrometers and lux meters in measuring the said elements as well as post-occupancy evaluation, which involved 30 respondents for each case (total 90 respondents), to determine their perception of comfort and its effect on their health and absenteeism rate. Data collected were analysed using Statistical Package for the Social Sciences. Findings – The results suggest that employees did not find luminance level uncomfortable, when compared with room temperature, thus proving that employees are more sensitive to room temperature comfort. Furthermore, when the room temperature comfort was low, significant correlations were found with health-related issues such as feeling “stuffy”, being easily tired and having difficulty concentrating. Originality/value – This paper investigates the relationship between employee performance and a comfortable workplace environment. It could be concluded that an uncomfortable environment in an office workplace leads to health-related issues as well as increasing the absenteeism rate. High levels of employee absenteeism lead to decreased employee productivity, therefore affecting their work performance.

Purpose – The purpose of this paper is to identify the most influential buildings elements in term of the cost for timber restoration works. Design/methodology/approach – The research employed the case studies methods with questionnaires surveys. Two case studies were chosen and questionnaire surveys were distributed to contractors and consultation companies. The cost was identified based on the elemental cost analysis of historic timber buildings. Findings – The restoration of historic timber buildings in Malaysia has grown rapidly, especially in the UNESCO world heritage sites, Melaka and Penang. Data obtained on the restorations of timber buildings show that the most influential elements were upper floors, roofs and walls. Termites’ invasions and the lack of building analysis were found to be the major issue in timber restoration works. In addition, the availability of timber material contributed significantly to the increase of cost for restoration works. Originality/value – The cost for every element...
