REALISATION :    RENOVATION MINERGY-P in ATHENAZ

Facades
	Isolation
Windows
	Thermal bridge
Floor heating system
	Ventilation

To be consistent, I couldn't advice others to increase the energy efficiency of their houses without showing the example.

So I have made a total renovation of my home dated 1966 to a low energy comsuption bulding (type Minergy-P). The following works had to be carried out :

• isolate west, north and south facades with a 30 cm-thick mineral isolation material
• isolate the separation between heated and non-heated spaces (for example : basement's ceiling, playroom's walls and floor) with 20 cm of Multipor
• break the balcony thermal bridge (concrete slab sawing and isolation)
• isolate underground walls up to 1 meter
• change windows for triple panes
• create an entrance airlock on the northside
• install a very low temperature floor heating system
• install a breakdown double flow with heat recovery
• build a Canadian well

This way the cost of heating oil has been reduced approximatively by 70%.

Improving my home's energy efficiency gives me the same revenue that I would get from investing in a bond at 2,5%. This performance will be reviewed upwards as the energy costs are increasing. Moreover, I benefit from a more confortable home and preserve the environment.
