Maison solaire passive

Résumé

Une maison solaire passive est une habitation de type habitat passif, c'est-à-dire conçue pour bénéficier au maximum du rayonnement solaire, grâce à sa conception (forme, orientation, répartition des ouvertures, isolation, inertie thermique...), à la qualité de ses composants (murs, toiture, sol, fenêtres et portes…) et à une ventilation performante qui permet de maîtriser les apports d'air et le degré d'humidité. Elle offre, par la constance de sa température intérieure et les très faibles écarts de température entre l'air et les parois (murs, vitrages), un grand confort ; ses grandes ouvertures vers le sud lui donnent une très grande luminosité. Elle est également particulièrement saine, par la maîtrise de l'hygrométrie intérieure et le bon renouvellement de l'air. En Allemagne, elle répond aux exigences du label Passivhaus délivré par le Passivhaus Institut, qui a pour exigence essentielle une consommation d'énergie de chauffage, pour le bâtiment, inférieure à par an.

Massive 3D models and physical data for building simulation at the urban scale

José Ramón Vazquez Canteli

In a time when governments are pursuing increasingly ambitious energy efficiency goals, building energy simulation at the urban scale, combined with the high availability of physical data, can help in performing this task. The purpose of this study is to describe the methodology used to create a geometrical 3D and physical model for the city of Geneva, and to analyze the energy-saving potential of several refurbishment measures, including the installation of more solar PV panels, for different climatic scenarios. Different sources of data are used to build a PostgreSQL database with the physical and geometrical characteristics of the buildings. The virtual models are simulated with CitySim, a program that estimates the energy demand for heating, cooling, and lighting of every building on an hourly basis. The models include, but are not limited to, the shadowing effect among the buildings, the passive solar gains through glazing, the internal gains due to occupants’ activities, the solar reflectance and infrared emissivity of the surfaces, and the materials that provide the buildings with insulation from the outdoors. This research will also provide some results that can be used by the municipal authorities of Geneva as a reference to quantify the decrease of the energy demand that they can expect to achieve in the next years.

Since the second half of the XX century, the way new urban areas have risen next to the ancient/traditional parts of cities has been vastly unsystematic, often altering the original natural landscape and/or urban morphology significantly. This has sometimes generated a mixture of architectural languages and technologies without any regard for the connectivity of a community as a whole. Despite the revival in current design practice of passive design solutions, studies on the influence of contemporary urban settlements on the thermal behavior of traditional buildings are still very limited. The aim of this study is to investigate, through simulation-based assessments, how contemporary urban settlements and buildings affect the bioclimatic features of existing historic architecture. The analysis considers some case studies located in different countries and climates and moves from a micro-urban to a building scale.

The Soralux Daylighting System: Passive Solar Illumination for Deep-Plan Building Spaces

Daylight is a valuable resource for both energy and human health. However, this resource is often underutilized in buildings due to the difficulty of controlling the changing qualities of daylight. Deep-plan building spaces pose an especially challenging problem because traditional sidelighting strategies are only effective for workplanes adjacent to the facade. Infrequently adjusted shading systems can also limit the availability of daylight. A number of advanced daylighting systems have been developed that attempt to address these challenges with varying priorities and success. This thesis proposes a new technology named the Soralux Daylighting System. The system is passive, requires no shading adjustments, even under direct sunlight, and works well with deep-plan spaces on the order of 8 to 15 m deep. The Soralux system presents itself as a double-glazing window unit, allowing it to be easily integrated into curtain wall facades typical of deep-plan offices in large cities. Computer simulations using the ray tracing programs Radiance and TracePro were conducted to estimate the annual performance of the system. Variables such as facade orientation, sky obstruction, and climate were evaluated for their effect on system performance. The system was found to increase light levels by a factor of 2 to 10 compared to an unshaded window at depths between 8 and 15 m from the facade. Two physical mockups of the Soralux system were fabricated for testing. The first mockup tested was a small proof-of-concept prototype, while the second was a full-scale mockup which was installed in a Tokyo office building. The physical mockups were used to evaluate visual comfort and appearance. A monitoring campaign was also conducted for the Tokyo mockup and the measured data were compared with a Radiance model of the building space to validate the accuracy of the simulation results. The average error between simulated and measured illuminance values was 16%. Based on these results, recommendations are provided identifying which scenarios are well-suited for the system. The Soralux Daylighting System is scheduled to be permanently installed into a Tokyo office building in 2012.
