Owner approach of sustainability
This building very much fits in with the Horizon 2020 initiative set up by the European Commission. In effect, by that date, any new building must be “zero energy”. Neobuild wanted to get a six-year head start on this regulation by constructing a building which heralds the arrival of smart buildings and which will use as much energy as it will generate. To do this, special heating and ventilation systems have been set up, which will be supplied by a number of renewable energy systems (such as solar panels, geothermal energy, ice stores, etc.).
Alongside this purely environmental aspect, a lot of importance has been placed on the comfort of users, an equally vital component. This building will be regularly monitored and its users will play a key participatory role in this, being able to determine the heating or lighting levels, for example.
Finally, the construction techniques are obviously in line with the latest products on the market, or even experimental ones, such as for insulation or for planting roofs and walls.
The Neobuild building is a two-level solid timber structure standing on a concrete lower storey. The 500m2 ground floor is used for the plant rooms, a workshop for training and a meeting space for professionals. The two upper floors comprise offices, training and meeting rooms, with a total floor space of 1,000m2. The flat roofs are used for plant and equipment; they have a useable surface area of 560m2. The new building is connected to the IFSB building (Training Institute for the Construction Industry) by a triangular atrium made from a 3D web of metal beams. For moving between the different entrances to IFSB, Neobuild and the main private entrance to Neobuild from the road there are concrete-coated pan joist floors. The net surface area of this zone is 300m2. The main building is split in two vertically by a glass corridor, creating two staggered units perpendicular to the existing building. On one of these units, the wooden facade is arranged vertically whilst on the other it is horizontal, based on the aspect and exposure to the sun of the units. The external woodwork is fitted with over-sized frames in order to emphasise the volume of wood over the concrete base.
The atrium is partially enclosed at the sides using glass curtain walls in order to highlight the transparency of its role as a connection. Sections have been left vacant for experimental purposes. In order to target a reduction in energy usage and greenhouse gas emissions, innovative environmentally friendly, high-performance products have been used. These products meet the requirements for passive buildings, such as some of the windows which have electrochromic panes of glass. Different types of insulation have been fitted in each of the external walls and their behaviour is monitored using probes.
The building, produced in accordance with "passive" energy requirements, is air-conditioned throughout (heating/ventilation/cooling). In addition, three rooms have new ground-heating systems. The energy is supplied from a number of renewable sources such as geothermal wells, ice stores or bins or simply the outside air. Three heat pumps juggle the different energy sources to test the optimum configuration. Eleven lighting designs were assessed using LED technologies. The power required is less than 10W/m2.
The internal layout has been created by taking account, in part, of the lighting designs and the precise acoustic ratings to be achieved. As a result, a variety of different types of screed, indoor woodwork, false ceilings and acoustic wall panels are used.
The part-planted roof houses the solar panels, the weather station, the urban greenhouses with hydroponic or even aeroponic systems, along with empty spaces for future developments (such as a solar concentrator).
If you had to do it again?
Perhaps plan the project in a more optimal way, in full cooperation with the architect.
In effect, this would have allowed the building to be better designed and its construction could have been planned better, under the keen eye of the architect.
As the building is experimental, choices had to be made in the selection of materials used.
Yet, new materials are being developed constantly.
We are fortunate, therefore, that we can continually evolve the building, able to change this or that material over time.
Building users opinion
As part of a continuous improvement process, Neobuild has issued a satisfaction questionnaire to the occupants of the building and to visitors, in order to gather their views and comments and to assess any potential areas for improvement. These surveys have helped to enhance the level of comfort of the occupants. The results showed that the occupants particularly appreciated the lighting levels (e.g. electrochromic glass), the visible wooden structure which gives Neobuild Innovation Centre a welcoming feel, the roof-top greenhouse and garden, the sports equipment, the user-friendly kitchenettes and the individual control of the lights and the outdoor blinds.

The core of the Acti 9 Control system, the new modular smart Acti 9 Smartlink interface, sends the data from the Acti 9 devices to an automated controller or a monitoring system, using the Modbus serial line connection network.
All of the data are stored, such as number of cycles, consumption, running time, even in the event of a loss of power.
No configuration is required for the products connected.
The communication adapts automatically, when Acti 9 Smartlink is switched on, to the communication settings of the Modbus master (PLC, monitor).
Although the idea of a Smart Building is very well known in the press and in construction news, getting hold of equipment has not been easy. Schneider Electric has helped to consolidate smart concepts devised during the design stage.

DuPont™ Energain® is made of a polymer which contains a phase-change material (PCM) made of paraffin wax.
It means that excess heat in a room can be absorbed when the temperature rises and, conversely, can be returned when the indoor temperature falls.
This product is traditionally placed behind a plasterboard but in the NIC this product has been placed in the ceiling to test its effectiveness in this location. As a result, it has not been the success it deserved.

The "ice store" is a buffer store of solar energy, outdoor air, ground energy and other natural resources.By using the latent heat of the water, this system supplies the primary energy required for the heat pump to work throughout the heating season with no well!
This idea, which is as old as time, has re-emerged with precisely-scaled systems. The implementation and optimisation times are quite long. We have not been completely satisfied but it remains a promising product.

Wood-cement construction products, environmentally friendly, blocks and floorings.
To start with, the workers were resistant to this new material because they weren't used to wooden materials. The first two rows which were laid helped them to see that it is similar to fit to concrete blocks and that it was much more comfortable to handle thanks to the wood.
Woobago's system and structures use 100% biodegradable raw materials and locally sourced products, with all that this implies in terms of quality and beneficial impact for the social and economic fabric of your region. Furthermore, these raw materials are rapidly renewable: bamboo, indigenous wood, straw and local clay.
As straw is not very widespread in innovative construction, it attracts a lot of curiosity from visitors in the experimental connection area.

Foobot is a smart online device which can measure air quality in the home.It makes a number of claims: tracking allergy-causing particles, keeping chemical components under control which stem from our mobile devices and controlling the correct temperature and humidity level to create a more pleasant living space for the whole family.
A new arrival on the market, this additional piece of equipment helps to consolidate and cross-check the results obtained using the various different air sensors included in the rooms.
The solar panels which use back contact technology are made of single-crystal solar cells which are currently considered to be the best technology on the market.These cells have the notable feature of generating a very high load voltage, even in high temperatures and provide an excellent load input even with very low irradiance.
As solar panels are already a well-known product, it was straight-forward to incorporate them.

CW2000 is a filling made of wood shavings with a mineral coating and defined cubic chip form.The special combination of materials allows the beneficial properties of the wood and mineral substances to be practically combined.
Putting this material into service beneath a screed posed a number of questions for the companies. However, the implementation phase was particularly appreciated by the workers and, after one year in service, the results are still very positive.

Reasons for participating in the competition(s)
Parce qu’il est un véritable laboratoire intégrant plus 100 matériaux, produits et systèmes différents, ce bâtiment de haute technologie « nearly zéro énergie » de 2200 m² impressionne beaucoup. A la fois expérimental et pédagogique, il offre de nombreuses possibilités en matière de monitoring et de tests grandeur nature.
Le Neobuild Innovation Center, en tant que véritable Living Lab, intègre de nombreuses technologies innovantes, telles que le projet Neostein® développé par l’entreprise IMSIM, qui constitue un parcours pédagogique du bâtiment.
C’est un bâtiment vivant évolutif, non seulement en fonction des besoins de ses occupants, des entreprises, qui ont l’opportunité de découvrir et de faire découvrir de nouveaux matériaux ou des technologies innovantes, mais qui progresse également continuellement pour tenter de répondre aux exigences environnementales naturelles et nécessaires.
C’est pour ces raisons que Neobuild Innovation Center est un très bon candidat pour ces quatre catégories.
Matériaux bio-sourcés et recyclés
L’utilisation en majeur partie du bois massif, de la cellulose, du bois-ciment, de granulats de pierre, du bardage bois et d’une peinture 100% bio-sourcés nous positionne favorablement pour défendre l’engagement dans les matériaux bio-sourcés de la grande région.
Les forages géothermiques, les bacs à glaces, les corbeilles enterrées, les panneaux solaires thermiques présentent diverses sources d’énergies renouvelables pour alimenter les trois pompes à chaleur du bâtiment.Ces dernières sont fournies en électricité par 7 systèmes de panneaux photovoltaïques et le système d’énergie inépuisable par excellence, l’énergie humaine.
Sante & Confort
Le confort des utilisateurs était une des préoccupations principales à l’origine du projet. Pour y répondre au mieux, il a fallu définir le concept de « confort » pour chacun. Suite à quelques interviews,un compromis respectant confort et environnement a été établi. Aujourd’hui,chaque utilisateur bénéficie d’un espace lumineux et fonctionnel tout en acceptant que les chaleurs estivales doivent être gérées par un comportement adapté et non en ayant recours à la climatisation. L’utilisation de matériaux régulant naturellement l’hygrométrie des espaces, une ventilation adaptée et la présence de matériaux inoffensifs tels que les peintures naturelles et les colles sans formaldéhydes, sont autant d’éléments qui prodiguent un air sain aux utilisateurs. Celui-ci est contrôlé par de multiples capteurs qui alarment le gestionnaire en cas de déviance. En parallèle de ce contrôle, des enquêtes de satisfactions sont menées régulièrement afin de répondre aux besoins des utilisateurs en constante évolution.
La présence de plus de 1500 capteurs à multiples fonction permettent un monitoring rigoureux du bâtiment et de ses installations techniques afin d’être en adéquation parfaite avec les fonctionnalités premières du bâtiment. De plus, les technologies misent en place permettent la réalisation d’un délestage de premier niveau. L’aspect « Smart » du bâtiment est également soutenu par des utilisateurs avertis qui intègrent aisément le concept et qui se veulent actifs dans son évolution.
