Description du projet : Pour faciliter l'optimisation énergétique à grande échelle pour tous les bâtiments jusqu'en 2030 (objectif de l'OFEN), le projet ProRen se propose de créer un cadre facilitant : une compréhension de l'ensemble du processus de rénovation, le développement d'une approche globale de la rénovation tenant compte de décalages de compé-tences entre les acteurs et d'une méthode de récolte et de traitement « intelligents » de données. Ce cadre permet le montage des projets inter-instituts dans le développement futur du thème fédérateur « Interventions sur le bâti existant ».

Description du projet :
Sur la thématique des smart cities, l’évolution récente des capteurs, des réseaux de communication et des algorithmes de traitements big data ouvrent des perspectives inédites pour l’analyse de nos cités. Un premier objectif du projet sera d’équiper le quartier BlueFactory de Fribourg et les carrefours adjacents avec des plateformes de capteurs compatibles « Internet des Objets » et évolutives. Les capteurs seront capables d’inférer le trafic, de mesurer la pollution de l’air, la pollution sonore et l’illumination ambiante. Un second objectif sera de traiter les informations collectées afin de mettre en place différents services d’analyse permettant d’estimer des indices de qualité de vie au niveau des quartiers et de la ville. Finalement, il s’agira de mettre les données récoltées ainsi que les plateformes de capteurs à disposition des équipes du smart living lab pour leur propres projets.

L'apparition de nouveaux types d'environnement de travail cherchant à la fois la satisfaction des usagers et l'accord avec des types de travail spécifiques à l'organisation des entreprises demande une compréhension systémique du confort de l'usager dans les bureaux. Le projet Multi-Confort répond à cet enjeu en prenant en compte les trois composantes du confort (physiologique, psychologique et fonctionnel) et en cherchant les corrélations entre les facteurs ambiants, les types (routines) de travail, l'occupation effective et l'usage des équipements.

Summary:
Providing users with relevant information raises their awareness on the influence of their behavior on the energy consumption and comfort in their workspace. A user-building interface was developed as part of this research through a co-creation process. It provides the occupants of monitored offices with information on their electricity and heating consumption, comfort indicators (temperature and air quality), light control and hints and tips on how to improve their behavior. This contribution describes the methodology used to improve the behavior of users in a pilot building and the results of a 32-week measurement campaign.

This contribution presents a possible use of the Building Information Model (BIM) for the implementation of Building Management Systems (BMS) and proposes tools and methods for each critical step of the process. The resulting designed process enables each building stakeholder to work at an earlier stage on the digital model located on a dedicated server. This paper proposes a novel and integrated approach to building-data management and analyses the main obstacles and limitations that may currently affect the practical implementation.

Buildings consume a significant amount of energy, estimated at about one-third of total primary energy resources. Building energy efficiency has turned out to be a major issue in limiting the increasing energy demands of the sector. Literature shows that building user behavior can increase the efficiency of the energy used in the building and different strategies have been tested to address and support this issue. These strategies often combine the quantification of energy savings and qualitative interpretation of occupant behavior in order to foster energy efficiency. Strategies that influence building occupant behaviors include eco-feedback, social interaction, and gamification. This review paper presents a study conducted on the state of the art related to the impact of building user behavior on energy efficiency, in order to provide the research community with a better understanding and up-to-date knowledge of energy, comfort-related practices, and potential research opportunities. Achieving and maintaining energy-efficient behavior without decreasing the comfort of building occupants still represents a challenge, despite emerging technologies and strategies as well as general research progress made over the last decade. Conclusions highlight eco-feedback as an effective way to influence behavior, and gamification as a new opportunity to trigger behavioral change. The impact of user behavior is difficult to quantify for methodological reasons. Factors influencing human behavior are numerous and varied. Multi-disciplinary approaches are needed to provide new insights into the inner dynamic nature of occupant’s energy behavior.

The energy transition raises the questions of the performance, the facade potential and the architectural integration of photovoltaic solutions. In this context, understanding the obstacles and opportunities of the market development in a holistic way is a major issue. This contribution relies on the results of the SNSF PNR70 ACTIVE INTERFACES project (sub-project 05) and emphasizes on the aspects of architectural integration (design and technique) as well as on socio-economic aspects, normative and legal aspects and knowledge transfer between the different actors along the value chain of BIPV products. This research considers the urban residential renewal of the city of Neuchatel as a case study in order to evaluate the market potential of BIPV. The used methodology consists in a pragmatic approach, interviewing architects and owners on choices they made for their specific renovation project as well as their viewpoint and beliefs towards PV and BIPV. A planned behavior acceptance model was used to evaluate the influence of different factors such as outcome appraisal, performance beliefs, effort expectancy, normative beliefs and motivation to comply - which generate the behavioral intention - as well as personal skills, environmental constraints and facilitating conditions, which enable action. The findings of this study give a better understanding of the market potential of BIPV in urban renewal process and provide new perspectives on public policies and existing incentive mechanisms. Based on the analysis of stakeholders interviews, practical recommendations that could significantly change current practices in this area are proposed.
The consumption of buildings is strongly influenced by the behavior of its occupants. Therefore, it is important to make users aware of their consumption and help them reduce it. The THE4BEES project presented in this contribution aims (1) to raise users’ awareness of building energy consumption and (2) to optimize comfort and energy efficiency through better user-building interaction. The designed method gives an important role to the user, while increasing use and acceptance, which is sometimes difficult to achieve with fully automatic solutions. To achieve this, a user-building interface (ICT application on a tablet) was developed. This tool provides occupants of two monitored offices with information on their electricity and heating consumption, comfort indicators (temperature and air quality), light control and hints & tips on how to improve their behavior. The implemented architecture system is multiprotocol in order to communicate with sensors and actuators of any type and any manufacturer. A 32 weeks measurement campaign has led to a significant reduction in the electrical consumption of lights and electrical appliances. Air quality in the working environment was also improved thanks to the user interface. This research highlighted that including occupants early in the design process of a user-building interface that meet their expectations is a good way to inform them and make them realize the impact of their behavior on the energy consumption.
