Envelope performance

• Envelope U-Value : 0,28 W.m^-2.K^-1
More information :

very strong thermal insulation with biosourced materials (Thermibloc, wood wool insulation) + inertia with system isolated from the outside
Mixed indoor, Foam Glass in under basement, Cork in under basement, Misapor under slab

• Building Compactness Coefficient : 0,34

Indicator : n50

• Air Tightness Value : 0,41

Users' control system opinion :

very positive: external BSO controlled by facade according to the sun, no overheating, very good brightness, in the morning all the BSO are opened automatically before the arrival of the occupants. Use of natural light in addition to artificial light, brightness controlled by the presence detection system and light sensors.

More information

The calculated performances are given on the basis of the PHPP calculation which is rather pessimistic, the first real consumptions are below these calculations.

ALGO

Algo 15, rue de la Motte 35770 Vern sur Seiche

 http://www.peinture-algo.fr


Product category : Second œuvre / Peinture, revêtements muraux

Painting based on seaweed, Breton manufacturing, which contributes to the quality of indoor air in our premises. Respect for the environment, promotes the short circuit by integrating raw materials from local and renewable resources. This product has a very low carbon footprint
Made in local (Breton algae and manufacturing plant VERN SUR SEICHE)

It is an extraordinary painting in any respect (application, smell, resistance, washable, rendering, colors ...)

THERMIBLOC

THERMIBLOC

XELIS GROUPE, ZA Piquet Sud Est 35 370 ETRELLES

 https://www.thermibloc.fr


Product category : Gros œuvre / Structure, maçonnerie, façade

Thermibloc, formwork block made of mineralized wood fibers, incorporating insulation on the outside,
The insulation used is the wood wool on 16 cm thick, this complex (thermibloc with wood wool) was set up for the first time at the health house of Vern sur Seiche (Voier additional information about the product )


The insulation placed outside ensures a continuous mantle wall without thermal bridge
The concrete load-bearing wall of floors brings the benefit of a strong inertia, thus an excellent phase shift and limitation of temperature variations
Wood concrete highly permeable to water vapor participates in hygrometric regulation, it contributes by its acoustic absorption to attenuate the acoustic waves and thus creates a soothing interior atmosphere
This material is perfect for a passivhaus health home

Construction and exploitation costs

• Cost of studies : 10 800 €
• Total cost of the building : 1 490 000 €
• Subsidies : 98 000 €

Energy bill

• Forecasted energy bill/year : 5 000,00 €

Real energy cost/m2 : 5.15

Real energy cost/none : 200

Water management

• Consumption from water network : 10,00 m³

Water Consumption/m2 : 0.01

Water Consumption/none : 0.4

Optimization of water consumption by automatic electronic valves.
Minimum water consumption by the flow and the right amount needed.

Indoor Air quality

The use of paint with a very low emissivity level (Algo), the installation of a very high efficiency CTA, lime renders, the use of Métisse (recycled cotton) insulation and Fermacel ensure the hygrometric regulation of the building.

The set contributes to the indoor air quality of our premises .In the meeting room, CO2 detector that controls an air flow control damper.

Comfort

Health & comfort :

VOC (volatile organic compounds) is less than 1g / liter or 10 times less than the minimum allowed by the A + standard.

The Métisse cotton wool provides exceptional acoustic comfort The triple glazing freed us from the cold zone and limits air movement.

Calculated thermal comfort : Inner summer temperature between 20 and 25 ° C, indoor winter temperature between 20 and 22 ° C

Measured thermal comfort : Room-by-room regulation of the temperature by ceiling radiating slabs, setpoint temperature adjustable in each room.

Acoustic comfort :

The mixed race (recycled cotton wool LE RELAIS) brings exceptional acoustic comfort.

Fibralith false ceilings (ORGANIC PURE brand KNAUF based on cement-coated wood fiber, forming an acoustic wave-absorbing surface) contributes to the acoustic and visual comfort of circulations and waiting rooms.

GHG emissions

• GHG in use : 1,50 KgCO₂/m²/an
