The energy and building research community acknowledges the importance of including occupants' wellbeing in the evaluation of building energy performance. Particularly in office buildings, occupants' comfort assessment is not yet a common practice, partially due to the shortcomings of the comfort assessment activities. Contextual factors such as the organizational culture, occupants' personality traits and emotional states, and the building and research measurement infrastructures do interact with occupants' motivation to report and influence their actual reporting behaviour. By means of an in situ mixed method approach combining real-world research and user-centric methods, this study investigates the impact of a reporting-based comfort assessment. Two buildings, representing different organizational cultures, were selected to study the influence of reporting behaviour on comfort assessment. The buildings were equipped with innovative indoor climate monitoring and in situ comfort reporting infrastructure and 2-week field studies were conducted in both buildings. By discussing results from these studies, this paper contributes to the development of building research methodologies of indoor climate and comfort assessment by providing practical experience in embedding comfort reporting behaviour in the analysis of comfort assessment. A contextual typology of reporting behaviour is introduced and its implications regarding the reliability and validity of comfort reporting techniques are discussed.@en

This chapter presents an approach for organising research and innovation in the Living Lab context, where context research instruments, as well as conceptualised, developed and tested prototypes are integrated in one hardware and software platform (BOCS platform). The BOCS platform allows collecting of sensor and building management data, self-reporting of subjective information by users and providing feedback to users through a variety of channels. By this, the platform supports iterative cycles of context researching, co-creating, implementing and testing of solutions. The initial goal for the use of the platform is to enable creation of solutions aiding office occupants in improving their comfort while reducing building energy use. This goal is attained by enabling iterative identification and a gradual build-up of in-depth understanding of involved social practices, and incremental introduction and evaluation of ways to support the change of these social practices through monitoring, self reporting and feedback in office environments. The chapter outlines the organisation of the proposed process in detail. The approach is further positively evaluated based on the outcomes of a preliminary case study. It is finally suggested that in the future the approach may be applied to other Living Lab situations where complex challenges are faced and fast results are expected.

Energy efficiency in office buildings has focused primarily on technological developments for the optimization of energy building performance. In this effort occupants’ behaviour has often been simplified or ignored. This in turn has resulted in solutions that either have a short-term impact on energy savings or in the long-term the measured impact differs largely from the theoretical estimations. A user-centric view is therefore needed to capture the complexity of occupants’ behaviour in the design of energy saving technologies. Social practices theory describes this complexity as the everyday practices that are characterized by interactions between people’s diverse sets of values and competences and the materials of the environment in which they engage in. Whereas people are constantly adapting their environment to meet their needs, they often perceive an ‘inability to act’ when explicitly asked to change. This opens an opportunity for the design research community to reconsider design interventions not as ends for behavioural change but as means to support practitioners in their discovery and appropriation of materials, competences and values to achieve optimal changes. From a design research perspective supporting these processes requires methods that a) empower occupants to create, test and assess interventions and b) fit in their everyday activities. This paper presents an in-situ and practice-based design process implemented in Living Lab settings with methods that aim to support a multidisciplinary team in the development of reflective design interventions to empower active involvement of building occupants in appropriating changes. The paper presents preliminary findings of an ongoing project and envisages future work to better understand hierarchy of practices and its potential impact on how occupants engage in changingactivities.@en

Improving energy efficiency in commercial buildings is of great importance, given the large percentage of energy consumed in the sector. However, the incentives to save energy in these environments are unusual. From the perspective of managers, energy consumption is only a very small part of the financial burden of companies in comparison to materials, rent or salaries, and thus, economic incentives have a low impact in these environments. On the one hand, unlike in home environments, occupants of office building do not see a direct financial effect on their energy related occupancy practices, as so, their incentive is also not a monetary one. Thus, to effectively reduce energy consumption in office buildings, a different approach should be followed. The Building Occupancy Certification System (BOCS) project aims at developing a building evaluation system focused on the building’s occupancy instead of its technical or physical characteristics. The objective of BOCS is the reduction of energy consumption in office buildings while improving indoor conditions. In this regard, the improvement of indoor conditions and thus, productivity, is the incentive for company managers and staff to implement the BOCS system. Though, keeping environmental awareness visible in the agenda. This paper presents the preliminary results from the first BOCS pilot study in the Netherlands, regarding the building performance in terms of thermal comfort and indoor environmental quality. This study focuses on the data collection and analysis.@en
