Owner approach of sustainability
CoRI:"The first goal was the lack square Indeed, the number of employees rose sharply from 2010 to 2014 and the building became too small The second objective concerned the modernization of our image through our corporate identity and more widely.. our communication. with a dilapidated building, we had trouble convincing potential customers that we are a modern research center, dynamics and advanced technology. as part of this building, from the beginning we wanted to integrate reflection of the environment. in fact, this line is one of our three privileged areas and it was essential for us that the building reflects our commitment to society in terms of environment. it was our first experience in this type of investment and this is why the helium3 office was selected because it was able to integrate this dimension in the project. "
Our will, realizing this project was to design a building in the image of its occupant, the company CoRI (Coating Research Institute). To do this, we have introduced two concepts to carry the project. 1 / The color chart CoRI is an active research center in the field of paints. When thinking "paints" is believed "colors" or rather "range of colors." The concept of the color chart we therefore appeared as an image to the strong symbolic and identity pronounced character to the building, two qualities in our redevelopment optical readability CoRI its site. The graphic image of the facades wants an interpretation of the activity in the presence in the building. The extension takes the form of an elegant wooden cladding façade ribbon around which the composition is drawn. It is characterized by alternating large windows and Rockpanel tone white, all punctuated by signs with the colors of the company. The tape is fastened to the existing building, defines the outline of the new volume, and gives the building a new entrance at the junction between the old and the new. The existing building is insulated and encased with Rockpanel white. The colored buttons here are made by large sunshades to control solar gain. 2 / high-tech opposition / sustainable Durability, functionality and performance are three criteria that focuses its activity in the CoRI. In this idea, the objective was to create a building designed in an intelligent and thoughtful way, combining two aspects that our priori opposed to: high-tech and durable. In the collective mind, a "sustainable" building is perceived as a building constructed from natural materials with traditional techniques or forgotten (timber frame, coated lime or clay, ...). Conversely, when talking about a high-tech building, we imagine rather large windows, clean lines and advanced technology, or even a "smart" building. Through this project, we want to change prejudices and design a building both environmentally friendly and at the forefront of today's technologies. To achieve this, the principle is to put technology at the service of ecology. Thus, when designing the project, several thrust studies identified the optimal solutions: Dynamic Simulation, PEB study of natural and artificial lighting study, study of solar masks, blower-door, analysis of the life cycle, etc. . Moreover, during the life of the building users and visitors can be informed and aware of sustainable development: teaching screen that provides real-time information (consumption, temperature, ...), visible natural materials, dry basin green roof, etc.
If you had to do it again?
CoRI: "As regards us, we really have no negative point if we would change it again on the type of materials in relation to their implementation but especially compared to companies that have been selected for this project. It is true that the implementation of the siding on existing building was tedious. this could have been avoided if the company had had a better experience on the implementation of the selected panels .... It seems that risk can never be avoided because they are the architects who select the materials and then these are the companies that implement them and they sometimes commit without really knowing the risks / challenges related to particular materials ... .. Finally even if it is true that the beginning was a bit difficult to find a temperature equilibrium in the different spaces (rooms, corridors and laboratories), ultimately it is a matter of adaptation, we must change the way General to address this type of system. Once accepted this finding, we went on a completely different setting .... In the end it works. "
Building users opinion
CoRI: "In general, workers are very happy with the comfort of their offices and other work spaces The lighting is good and does not tire the end of the day Soundproofing is generally good.. whether in an office or between offices. regarding the quality of indoor air, we selected paintings without much of VOC emissions. There was never any comment on that. the thermal comfort will be tested next winter since the last settings were selected after severe cold and for the moment we can not say that we suffer from heat waves. to see the use ...

Second œuvre / Menuiseries extérieures
Rockpanel panels are prefabricated compressed mineral wool and amalgamated with thermosetting binders. The outer surface is coated with four layers of polymer emulsion paint in aqueous phase, available in a rich palette of colors. Rockpanel suitable as facade cladding, finishing panels and roof details and perimeter trim (soffits, exterior ceilings, etc.).
Rockpanel were used to achieve the cladding of the existing building and extension, but also to make the sunscreens that provide the colored buttons on the existing building. In addition to their environmental benefits (BRE label A + / A), Rockpanel allowed to reproduce on the facade identity colors of society, through collaboration with Akzo Nobel has provided adequate paint.
Second œuvre / Cloisons, isolation
Cellulose is made from waste paper newspapers. The i3 cellulose is produced in Belgium on a highly efficient production line. Its lambda value of 0.038 W / mK allows it to compete with insulation of mineral origin.
The cellulose was blown into the timber frame facades (22 cm) and the main roof (34 cm in average).
Wood fiber insulation Steico Flex
Second œuvre / Cloisons, isolation
flexible and compressible insulation panels wood wool. lambda value of 0.038 W / mK.
This natural insulation material is very suitable to be placed between the rafters of the technique against bulkhead. In it also pass various techniques of small diameter such as water supplies or electrics pipes. This technique against bulkhead also allows not to break the air seal during placement of wall mounts.
Heat treated wood siding DC-Wall
Second œuvre / Menuiseries extérieures
This ayous cladding ensures outstanding stability on both the rigorous care of during sawing. Softwood ayous is subjected to heat treatment with steam, under conditions of high temperature and high pressure that alter the long term. In a climate like ours, subject to intense fluctuations in temperature and humidity, wood so changed remarkably resists better to the formation of cracks and is ideal for the application of coatings. The four kilns at the port of Ghent has a capacity of 1000 m³. The company is certified FSC since 2008.
This cladding ayous heat treated and FSC label was chosen because it presents an interesting aesthetic, without knots, and requires no chemical post-treatment using heat treatment carried out at the manufacturer. The profile used is a "perforated false" giving the impression that the slats used are very thin. The angles tabs cutouts give a very neat finish to the wooden strip.
reversible heat pump AWR-HT
+33 1 (0) 1 30 95 19 19
Génie climatique, électricité / Chauffage, eau chaude
reversible heat pump with high efficiency air source for outdoor installation, high temperature water. The entire range reached a much higher level of efficiency to the levels provided by the class A energy savings (heating).
Pump aerothermal heat of a heating power of 71 kilowatts is placed on the roof of the existing building. In the extension, the heat pump supplies the heating circuit with the ground. In the existing building, it feeds two batteries preheat ventilation air. Because the heat pump is reversible, it can also be used to cool the building in summer. However, this function should not be used or bit by the building design.
Photovoltaic solar panels Professional 60 poly
rated power: 260 W Number of cells: 60
The 196 photovoltaic modules placed in the garden at the rear of the building achieve an output of 50.7 kWp for an estimated annual production of almost 43,000 kWh. The electricity produced will be completely self-consumed. Indeed, many measuring devices present in laboratories operate continuously and require huge electric power. The return on investment time is estimated at 6 years.

Génie climatique, électricité / Eclairage
LED luminaire with microprismatic cover CPD. A built-in exposed grid ceiling 60x60 cm module. Applications: offices, corridors, lobbies, meeting rooms, retail areas, waiting rooms, ... System LED luminaire luminous flux 4000 lm, connected load 40 W, luminous efficiency of 100 lm luminaire / W. Color neutral white light color temperature of 4000 K, color rendering index Ra> 80. Parameters of the rated lamp life: L80 rated life: 50000 hours.
Besides the aesthetic integration in false ceilings in mineral slabs, the choice of high performance luminaires allows to significantly reduce electricity consumption for lighting. They also limit the internal loads and therefore summer overheating. These devices were used to equip every office in the extension but also a part of the laboratory to replace outdated fixtures.
Synco building automation
The Synco 700 is a communicative and flexible pre-programmed controller. The Communication on KNX allows Synco controllers exchange a lot of information together: temperature, time programs, energy demands, defects etc. This also allows up all the information on a supervisory or directly on the web.
Centralized technical management (CTM) allows to retrieve data from different meters in the building. These fall in energy consumption (lighting, heating, ventilation and hot water are measured separately) but also other consumption (rainwater, mains water) and energy production (via photovoltaic). These data are then communicated to the shapes and the building users and visitors via the screen placed in the building lobby. The GTC also allows users to easily set up the technical facilities. They can for instance change the desired temperature in each room.
charging point for electric car
charging point for electric cars.
This terminal, located on the front of a parking space, allows users or visitors of the building that have an electric car recharging during their presence in the building.
The building is located on the CSE website (Scientific and Technical Centre for Construction). The choice of location of the extension is due to an energy reflection (North-South direction) but also a desire to provide better visibility to the building (to avoid confusion with the CSTC). The site already had a correct biological quality by the presence of a meadow behind the building and a wooded area on the back edge of the field. Interventions on biodiversity are: placement of two hives in the garden, various plantations around the building, extensive green roof, dry dock, new permeable parking. The majority of the site is verdurisée. DSUB = 0.0007 (destruction coefficient of useful areas for biodiversity) NSUB = 0.1 (coefficient of useful new areas for biodiversity) CBS = 0.85 (biotope surface coefficient)
Land plot area
10 854,00 m2
After work, the building has 30 parking spaces, a PMR up near the building entrance. A location on the ground floor is reserved for bicycles.
