TEMIS INNOVATION, A high environmental quality approach

ECO CONSTRUCTION

HARMONIOUS RELATIONSHIP BETWEEN THE BUILDING AND ITS ENVIRONMENT
The approach is integrated into the development of the site

> Vegetation that is part of the life of the building

• Vegetation in all its forms is an indispensable element for the balance of the ecosystems in which we live.
  Plants help improve air quality by increasing the production of oxygen and absorbing carbon dioxide.
• Plant cover reduces waterproof surfaces and prevents overloading draining systems.- Plantations accompany the project and help create pleasing views of the outdoor spaces, with high environment quality.

> All the technical support systems are placed on the roof, in specific spaces with aesthetic and acoustic protection and no visible discharge.If any outdoor technical systems are required, a terrace area is provided. This area is protected by partitions.

INTEGRATED CHOICE OF CONSTRUCTION PROCESSES AND PRODUCTS: CHOICE OF NATURAL MATERIALS

• terracotta
• wood
• Choice of materials that are easily recyclable: galvanised steel, aluminium cladding

> Durability
The materials used do not require any particular maintenance.

> Low-nuisance worksites
The worksite is organised and planned to reduce nuisance in terms of waste and keep the neighbours safe and protected from noise. The use of materials that generate little waste or recyclable waste is preferred.

> The worksite contributes to environmental quality
The environmental requirements of low-nuisance worksites are determined along with Health and Safety requirements.

> The objectives are:

• To limit the nuisance to the neighbourhood, particularly in the area of noise, dust and the appearance of the site for the other users
• To limit the health risks to workers
• To avoid worksite pollution (vegetable stripping oils, pre-treatment of wastewater before it is discharged in the natural environment, decantation of concrete laitance, agreement put in place with the municipality for connection to the drains etc.)
• Reduction at source of the production of worksite waste and selective sorting to meet the objectives of the law of July 1992

To ensure compliance with the law of July 1992 that requires that from July 2002, only final waste may be put into tips in order to prevent the inherent extra costs, selective sorting has been put in place of all the material output from the worksite.

ENVIRONMENTAL MANAGEMENT
ENERGY MANAGEMENT

>Heating:
The building design pays particular attention to thermal bridges: the principle of insulation from the outside, under the cladding, is a major plus.
Argon-filled low-emission double glazing has been used.
The premises that require a high volume of air renewal due to their conditions of occupation are fitted with high-efficiency double-flow units with recovery.

>Cooling and air-conditioning:
The building is the subject of a dynamic thermal study to assess the change in temperature on the basis of weather conditions, particularly in summer.
The building is designed so as to have high inertia. Combined with the use of high-performance glazing, sun shades and an earth pipe, that helps limit the need for air-conditioning to areas where the process generates heat and calls for compliance with strict requirements.
When the earth pipe is started up in summer, the temperature of the air introduced is 4 to 5° less than the atmosphere.

>Lighting:
Preference is given to natural lighting wherever that is possible, including in stairwells and common passage ways.
In order to use electricity more rationally and comply with decree NRT 0402 relating to the new thermal regulations, we have used low-consumption equipment for lighting the rooms:

>High-efficiency luminaires:

• flush-fitted high-efficiency fluorescent luminaires with concealment grille and very low luminance
• the qualities of the device makes it possible to finely adjust the number required, while providing the comfort required and reducing consumption

>High-efficiency fluorescent tubes:

• new generation of fluorescent tubes
• small diameter and low power rating (14 W instead of 18 W for the same efficiency)
• life of up to 20,000 hours, with the same luminous flow

>Electronic ballasts:

• These make for immediate lighting of the luminaire and does away with the starter, which creates interference due to the arcing generated by it
• They do away with the parasite magnetic fields emitted by the induction coil of conventional ballasts, which are harmful for laboratory activities (microscopy and spectrometry)
• They increase the life of lamps

>The lighting is controlled to suit the use of the room and the level of natural light:

• control by a presence sensor associated with a photo-electric cell that manages the artificial lighting according to the natural light
• remote control to force the automatic system if needed
• solution that makes it possible to consume only the power required at any time of the day

>Conclusion:
The solutions proposed generate savings of about 70 % on the electricity consumed for lighting

MANAGEMENT OF WATER AND RAINWATER:

In accordance with the legislation applicable in the zone in respect of hydro-geological conditions, which bans the infiltration of rainwater, rainwater is collected in a large tank under the parking area and carried away by a lifting pump to the drains, after a delay and in a regulated manner (study in relation with the Water department of the City of Besançon).

WASTE MANAGEMENT

Naturally ventilated and appropriate bin rooms have been put in place for selective sorting, in a series of equipment sheds placed on the edges of the car park.

MAINTENANCE MANAGEMENT

• That objective has affected the choice of materials, right from the design stage: particularly the building covering material: terracotta bricks and aluminium, galvanised steel, all of which requires no particular maintenance.
• - The shared equipment is placed in equipment terraces that are easily accessible (included with goods lifts).
• - The distributed fluids are metered in order to make it possible to analyse and manage consumption, in terms of both the distribution of costs and management by the users.

ELECTRICITY:

• the solutions proposed in target 4 help reduce the maintenance costs (increasing the life of fluorescent tubes)
• deterrent outdoor lighting is provided in the project to limit malicious damage
• A complete folder, including a maintenance proposal prepared by each contractor on the worksite, is supplied to the project owner.

ACOUSTIC COMFORT

The rooms generally have false ceilings to absorb sound reverberations.

VISUAL COMFORT

Optimum natural lighting for maximum comfort and minimum energy consumption.

HEALTH CONDITIONS OF THE SPACES AND AIR QUALITY

The choices made for power saving are fully compatible with air quality requirements: the technical installations are designed to renew the air to suit needs and occupation for the lowest power cost; in no event is one selected at the detriment of the other.
The air intakes and outlets are placed in order to meet those requirements and those of olfactory comfort.
