Owner approach of sustainability

This school, offering varied options in the industrial technical field and in the graphic arts, needed much more space to ensure a comfort worthy of the name to its students.

Since last September, this positive energy building has welcomed electricians, computer scientists and electronics engineers.

This concept, entirely prefabricated and with apparent structural elements, constitutes a real commitment for future generations with its green roofs and its rainwater recovery system.

Product category : Gros œuvre / Système passif

Prefabricated structure in insulated wood box

Fast system integrating thermal insulation and airtightness. Lets you really "pack" the building and avoid thermal bridges and weak spots for airtightness.

Reasons for participating in the competition(s)

PASSIVE BUILDING

- the heating requirement is maximum 15 kWh / (m².year)

- the cooling requirement is maximum 15 kWh / (m².year)

- the overheating frequency of the building above 25 ° C is maximum 5% of the occupancy time of the building (comfort criterion verified by dynamic thermal simulation)

- The air tightness of the building ensures a leak rate through the envelope of maximum 0.6 air changes per hour at 50 Pa (criterion verified according to report)

- the primary energy consumption is less than or equal to 90 - 2.5 x compactness (expressed in primary KwH / (m².year)
