Global performance contract

Energy consumption

• Primary energy need : 113,00 kWhep/m².an
• Primary energy need for standard building : 130,00 kWhep/m².an

Calculation method : RT existant

Breakdown for energy consumption : Heating consumption: 52 kWhep / m2
Lighting: 7 kWhep / m2
All uses: 78 kWhep / m2

The lighting is reviewed with LED luminaires managed by presence detectors in the halls and unheated premises (except the boiler room), this self-regulation system is completed by timers.

Joinery PVC range Design 5



Lorillard

 http://www.lorillard.fr/


Product category : Second œuvre / Cloisons, isolation

The PVC joineries range DESIGN 5 are intended for the collective buildings, individual constructions, as well for the new works as for the works of rehabilitation.
- These joineries are made from multi-chamber profiles in new generation PVC with reduced tolerances, tinted in the mass white tone Lorillard design, integrated into the REHAU range.
- The insulating double glazing of 28 mm total thickness according to the description of the CCTP of the lot Exterior joinery is certified CEKAL.
- The profile has 5 rooms, used to design the range Design 5 was studied to ensure a perfect thermal insulation of joinery. The range is equipped with double or triple glazing. (UW = 1.0W / m2K for triple glazing).

VMC regulating humidity and indoor temperature.

Ventilation and indoor air quality improved.

Construction and exploitation costs

• Cost of studies : 42 900 €
• Total cost of the building : 2 473 701 €

Indoor Air quality

The absence of building insulation and poor ventilation were detrimental to the indoor air quality and the comfort of the inhabitants. Thanks to this renovation:

• The ventilation maintains hygrometry permanently between 40% and 70%.
• The air change is permanent, and the sanitary quality of indoor air improved.

Principle of ventilation :

• Air entrances on joinery in dry rooms (living room, bedroom, living room).
• The low ventilation grilles (air inlets of damp rooms) are blocked by PVC sheets.
• The doors are cut off.
• Extractions of air are made by wet rooms: extraction vents connected to SHUNT ducts.

Benefits of renovation:

• Air quality and interior comfort.
• Disappearance of building pathologies due to poor renewal of indoor air (mold).

Comfort

Health & comfort :

The insulation and the double glazing make it possible to increase the surface temperatures of the walls. The work also helped treat thermal bridges (avoid condensation and mold formation around the windows). The renovation thus ensures a minimum comfort temperature for everyone and eliminates the associated health risks.

GHG emissions

• GHG in use : 19,00 KgCO₂/m²/an
Methodology used :

GHG emissions concern consumption of heating, DHW and cooling. Emissions GHG before renovation: 50 KGCO2 / M2 / AN

GHG and energy label according to CSTB THCEx V.1.0.3 engine

Life Cycle Analysis

Eco-design material :

The insulation of all the concrete facades was done thanks to a mineral coating. Detail of the insulation under plaster: 16 cm of mineral wool. Insulation of paintings, lintels and window sills using a 3 cm thick woolen insulation.
