The building stock is responsible for 24% of carbon emissions in Switzerland and 44% of the final energy use. Considering that most of the existing stock will still be in place in 2050, it becomes essential to better understand this source of emissions. Although the Swiss Cantonal Energy Certificate for Buildings (CECB) database has been used in pr...

Electricity storage technologies in buildings are evolving, mainly to reduce their environmental impact and to improve self-sufficiency of buildings that produce their own energy through Building-Integrated Photovoltaics (BIPV) installations. To maximize self-consumption - minimizing the import of grid electricity - photovoltaic (PV) systems can be...

The modern built environment is now connected. Multiple software and protocols are used in buildings of many kinds, thus creating a fascinating and heterogeneous environment. Within this context, applied research can be complicated and would benefit from a single data location across projects and users. The first version of BBData tried to solve th...

With the fourth generation of district heating networks in sight, opportunities are rising for better services and optimized planning of energy production. Indeed, the more intensive data collection is expected to allow for load prediction, customer profiling, etc. In this context, our work aims at a better understanding of customer profiles from t...

After an introduction, the main report includes two extensive chapters with a review of the European editions of the Solar Decathlon between 2010 and 2019. 65 solar-powered competition buildings with numerous innovations were created in the four competitions. While chapter 2 focuses on building design and construction, chapter 3 focuses on energy e...

This paper presents a novel approach for assessing comfort at the workplace, resulting from an interdisciplinary work between researchers in human-computer interaction, architecture, social sciences, smart buildings and energy management. A systemic comfort elicitation model including but not limited to thermal comfort, is suggested. A proof-of-con...

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 diffe...

Future buildings will more and more rely on advanced Building Management Systems (BMS) connected to a variety of sensors, actuators and dedicated networks. Their objectives are to observe the state of rooms and apply automated rules to preserve or increase comfort while economizing energy. In this work, we advocate for the inclusion of a dedicated...

New solutions are needed for manufacturing small and very precise components and micro-systems for the watch industry, for micro-optics (telecommunication), for medicine (processing biocompatible materials, medical implants, tools for ophthalmic surgery and for living cells manipulations) and even the chemical industry (micro-reactors). A small, ve...

Une plateforme de manipulation adaptée à des composants de 5 à 50µm a été développée dans le but d’étudier et d’optimiser les performances de répétabilité de positionnement. Elle contient un robot de haute précision ainsi qu’une interface permettant d’adapter différents types de préhenseur. Un microscope est utilisé comme système de mesure. Afin de...

High precision positionning and assembly as well as micro-machining require dedicated devices. These devices have to provide high repeatability and precision on several degrees of freedom (dof). High dynamic characteristics are also sought to reach short task execution time and a good robustness. This work shows how to design parallel robots with f...

High precision robots are often used for complex assembly or positioning tasks. One way to achieve high motion precision is to design mechanical systems based on flexure joints. Flexure joints (or flexures) utilize the elastic properties of matter, which brings avoidance of dry friction. Nanometer scale motions are then possible, without wear, mech...

In the fields of micro-positioning, micro-manipulation and micro-machining, the required motion precision is continuously increasing. The demand also increases for high dynamic performances (large bandwidth, high closed loop stiffness, etc.). In many cases an inappropriate mechanical structure prevents to achieve these objectives. The use of flexur...

In the fields of micro positioning, micromanipulation and micro machining, the required motion precision is continuously increasing. The demand also increases for high dynamic performances (large bandwidth, high closed loop stiffness.). In many cases an inappropriate mechanical structure prevents to achieve these objectives. For example backlash or...
