Owner approach of sustainability

Saint-Gobain designs and manufactures complete and innovative solutions for building sustainable high living comfort and low energy consumption, respecting man and the environment through the respect of those who have long been defined as its main "values": environmental sustainability , energy efficiency, security, temperature, sound, visual, indoor air quality, design. Respect for the environment is a fundamental principle for Saint-Gobain: Market leader in sustainable building, is one of the leading manufacturers of building materials recyclable and composed of recycled raw materials. Great attention is given to the Analysis of the Life Cycle of the product (LCA - Life Cycle Assessment). This is now at the center of studies of the Group being increasingly aware of its scope and the benefits it can produce. Its overall objective is to evaluate the environmental impacts associated with the various stages of the life cycle, with a view to environmental improvement of processes and products. In innovation, another key issue is the Ecodesign. The Ecodesign take into account any possible environmental impact of a product from its first planning, to avoid waste throughout its life cycle. To translate into figures the Group's commitment to innovation, 23% of Saint-Gobain sold today, did not exist five years ago. Through its unparalleled research effort, Saint-Gobain has been included for the third consecutive year in the Top 100 Global Innovators program, which identifies companies and research facilities most active in terms of innovation. The reduction of energy consumption and pollutant emissions, both direct and indirect, is a commitment to which the Saint-Gobain Group directs most of its resources. All industrial processes of Saint-Gobain are functional objective to limit air pollution, reducing direct emissions of carbon dioxide in the atmosphere. The main cause of energy consumption in Europe is represented by sector: Saint-Gobain develops, manufactures and distributes innovative solutions to make buildings more energy efficient and more pleasant to live About 30% of the turnover of Saint-Gobain is related to products and solutions for energy efficiency, achieved thanks to the insulation in interior and exterior, the wrapping and the roofs, with the use of glass wool, gypsum coated systems, thermal insulation, high performance glazing. Thanks to the materials Saint-Gobain for the building, the main advantage in terms of energy efficiency of a building is the reduction of heat loss through the facade and roof, resulting in energy savings that can reach over 75% of consumption initial heating, and an equally consequent economic advantage of relief.

Architectural description

Habitat Lab is a multifunctional space, which houses a showroom of solutions and products for the sustainable Habitat, meeting rooms, facilities for educational activities and spaces equipped for application demonstrations of products. A laboratory for monitoring the field of clean technology Saint-Gobain, for the development of innovation and research of new materials and manufacturing solutions. A training center dedicated to designers, contractors and applicators for the dissemination of building models of the future. The Center unites old and new, past and future of the building. The project involved the upgrading of fact a pre-existing structure, a wing of an old building of the 50 700 m2, and the construction of a new building of another 500 m2 (1,200 m2 of surface). Habitat Lab is designed with the most advanced and complete construction solutions to ensure high levels of energy saving, reducing consumption of non-renewable natural raw materials, the reduction of polluting emissions, comfort of use of the spaces. The structure is intended to be a point of reference for a new culture of living, inspired by the human welfare and environmental protection: a place to share the culture of sustainability.

Building users opinion

At the end of the training taking place in the Habitat Lab, is required guests to fill out a questionnaire about the perceived well-being during their stay at the Center: the questionnaire includes, for example, questions about the perceived temperature (feeling hot or cold ). The results of the interviews are used by staff that manages the Habitat Lab to constantly optimize the interior comfort.

Indoor Air quality

Indoor environmental quality is a fundamental value for Saint-Gobain, which finds full expression in the Habitat Lab. The materials used were chosen for low VOC content and controlled mechanical ventilation prevents the formation of mold and bacteria, helping to improve indoor air quality. The highlight in terms of air quality is the technology Activ'Air Gyproc Saint-Gobain, which has found wide use on interior walls and ceilings of some of the Centre: this technology is able to absorb more than 70% Formaldehyde in the air and turn it into inert elements, allowing a marked improvement in indoor environmental quality. This choice, combined with the monitoring of the concentration of formaldehyde in the environment has allowed the obtaining of a LEED point as innovative credit in the family Innovation in Design. In May 2015 (the latest month for which we have complete data at the date of the competition), the average concentration of formaldehyde in the month was 0.114 ppm. The minimum concentration reached in the month of May 2015 was 0,113 ppm, and a maximum of 0.118 ppm.

Comfort

Health & comfort : Natural light and views are guaranteed dall'amplissima portion of transparent envelope. The glass facade is placed in West made triple glazing solar control (Solar Factor g 0.25). This technology allows you to filter the excess heat of the Sun, so Habitat Lab can have light all year, reducing up to 75% summer overheating. The front window of the meeting room is created with innovative electrochromic glass (Light transmission adjustable from 63% to 2%; g Solar factor adjustable from 0.47 to 0.06): these glasses "Active", able to change the 'color intensity and, therefore, the light transmittance (intensity of incoming light) while ensuring thermal insulation and transparency. The set of architectonic solutions and choice of materials allows the center to have 95% of the surfaces employable with direct view towards the outside and to ensure that more than 77% of the surfaces benefit from natural lighting significant.

Measured indoor CO2 concentration :

Nel mese di Maggio 2015 (ultimo mese per cui disponiamo di dati completi alla data dell'iscrizione al concorso), la concentrazione media di CO2 del mese è stata di 908,60 ppm. La concentrazione minima raggiunta nel mese di Maggio 2015 è stata di 520,40 pp

Measured thermal comfort : Nel mese di Maggio 2015 (ultimo mese per cui disponiamo di dati completi alla data dell'iscrizione al concorso), a fronte di una temperatura media giornaliera esterna che è variata da un minimo di 15,6 °C ad un massimo di 25,4 °C, all'interno dell'Habitat

Acoustic comfort : Insulation solutions used Habitat Lab providing perfect protection from outside noise: the vertical envelope opaque, built dry, offers exceptional value of sound insulation of the facade, measured on site: DnT, w 66 dB. Even the glass façade with triple glazing offers a remarkable performance: D2m, nT, w 45 dB. The sound insulation between a local and another allows carrying out various internal activities simultaneously without mutual interference: the partition have a dry sound insulation in work of R'nw 50 dB. Even the acoustic correction is cured in every detail: for example, in the meeting room area of ​​the stage is reverberating to ensure that the speaker's voice comes clear and easily intelligible at all points of the room. Instead the ceiling and the bottom wall are made of sound-absorbing products to eliminate the background noise.
