- The contribution of stakeholders to the development and implementation of a sustainable built environment has emerged as crucial to the delivery of meaningful change. The inclusion of all affected parties can facilitate the development of patterns, structures and buildings that are sustainable in the social, ecological and economic dimensions. The slow development of a more sustainable building sector often results from the absence of knowledge about possible benefits because of financial constraints or the presence of conflicting interests. Furthermore, in most cases, measures to foster a sustainable building sector do not include all of the relevant stakeholders or are only one-sided. Based on a literature review of stakeholders in the building sector, this paper describes the stakeholders involved in the development of sustainable buildings and the challenges in stakeholder motivation. The practical case of the Network for Sustainable Construction Switzerland demonstrates how to foster sustainable construction by including a wide range of stakeholders and the need to address stakeholders with diverse initiatives. This case study supports the hypothesis that stakeholder motivation cannot be created by a single initiative; rather, a variety of actions are required to deliver change successfully.

- Purpose – The purpose of this paper is to research the impact of sustainable office buildings on occupant’s comfort and self-assessed performance and work engagement. Design/methodology/approach – The research consists in an empirical study of 18 office buildings and is based on survey data from almost 1,500 employees.Findings – The study shows that the building itself has a clear impact on the comfort level of the building user. Also, the positive impact of certain features, such as operable windows and the absence of air conditioning, can be clearly identified.While productivity is not directly correlated to comfort levels, work engagement is. Generally, the analysis shows that specific building aspects seem to have an influence on user comfort and with that, also an impact on productivity; however, this impact appears to be limited.Originality/value – This is a very important insight since this shows the connection between employee and company and thus demonstrates that a high user comfort can reduce the turnover rate of employees. Therefore, additional planning towards user comfort and social sustainability can beshown to yield real returns.

- Given the centrality of the price mechanism to resource allocation in market economies, the effect of sustainable construction on real estate prices has become an increasingly important empirical issue for market participants and policy makers in the real estate sector. Drawing upon a sample of approximately 2500 residential building units in Switzerland, this study assesses the effects of buildings’ sustainability on their rental prices. In contrast to the vast majority of previous studies that have focused on the price effects of eco-labels, this study investigates the effects of individual sustainability attributes. Overall, we find a positive relationship between the environmental performance of residential buildings and their rental levels. Sustainable building characteristics, especially those which enhance the water efficiency, the health and comfort level and the building’s safety and security, have significant positive price effects. It is argued that the unexpected negative relationship between energy performance and rental prices is attributed to the bundling of energy costs and rents in Swiss lease structures.

Sustainability and property valuation: a risk-based approach

- The proportion of sustainable property in the total building stock remains small. One reason is that the financial added value resulting from sustainability is not sufficiently taken into account in property valuation due to the tendency of valuations to lag behind market trends. Quantitative information is provided to integrate those aspects of sustainability relating to value into valuations and thereby contribute to the reduction of valuation lag. The Centre for Corporate Responsibility and Sustainability (CCRS) Economic Sustainability Indicator (ESI) measures the risk of property to lose value and the opportunity to gain value due to future developments (e.g. climate change or rising energy prices). Five groups of value-related sustainability features were identified: flexibility and polyvalence; energy and water dependency; accessibility and mobility; security; and health and comfort. By minimizing the risk of loss in value through future developments, those sustainability features contribute to the property value. Their effects on property value were quantified by risk modelling. As an indicator for future-oriented property risk, the ESI is integrated into the discount rate of discounted cash flow valuations. The approach was tested for plausibility and practicability on more than 200 properties.

- During the research project “Quality of Sustainable Buildings” (English: QSB, German: QNB), twenty seven buildings were investigated. Objective measurements (air quality CO2, air temperature, relative humidity) were performed and in addition, data on subjective judgements were collected using questionnaires. The analyses of this paper focus on the characteristics of ventilation (natural,mechanical and hybrid ventilation). Mechanically ventilated buildings indicated some advantages during the summer period with respect to the air temperature and in the winter with respect to the air quality (CO2). For naturally ventilated buildings, disadvantages during the winter were observed with respect to the air quality (CO2). The same buildings showed some advantage of a higher relative humidity in the winter period compared with the mechanically ventilated buildings. Subjective judgements did more or less correspond with the measured data. However, some parameters did not. Additional parameters for qualifying indoor air quality (here measured as CO2 - concentration) need to be considered. In addition, the study showed a quite good quality (measured and judged) for most of the buildings. In order to contribute to energy savings and to achieve a better level of indoor air quality(e.g. humidity), indoor air temperature could be reduced in winter without negatively affecting the comfort requirements of the office users.

Konferensbidrag (refereegranskat)abstract
- Energy consumption in office buildings depends on energy efficient construction and technology, but is also significantly affected by occupant behavior and facilities management practices. It is not clear, however, which reasons account for occupant energy consumption and what measures can be taken to realize latent energy saving potentials.The aim of this study consists in the analysis of causes of energy-inefficient occupant behavior and thus to provide background information for organizational measures targeted at the reduction of energy-consumption. In the present study we investigated these questions by asking office occupants about (a) their energy related behavior, (b) reasons for suboptimal energy related consumption and (c) their knowledge of energy efficient behavior in office buildings. 1174 occupants working in 12 office buildings participated in an online survey. The results show that up to 20 per cent of occupants report bringing personal electronic devices to the workplace. Around 10 per cent of the occupants have manipulated ventilation ducts in their work area in order to optimize their comfort. The study shows that the main reasons for not acting energy efficiently are not attitudes or goals. They relate to a lack of information, lack of incentives, and habits. This finding is further supported by the survey participants’ statements about the three most effective actions occupants can take to reduce energy consumption in the building. The most cited action taken by respondents to reduce energy consumption was to switch off lights when they were not required. There were a number of more effective energy efficiency measures that were not cited frequently (such as reducing heating), indicating a lack of awareness.It is recommended that organizations implement awareness and feedback systems tailored to organizational practices in order to change occupant’s habits. FM departments should take the responsibility of analyzing energy-related occupant behavior and of leading projects to increase energy-efficiency and sustainability in organizations.
