Architectural description

A zero-loss passive architectural design meeting the targets below:

Energy consumption

• Primary energy need : 259,00 kWhep/m².an
• Primary energy need for standard building : 449,83 kWhep/m².an

Calculation method : Other

• Final Energy : 81,99 kWhef/m².an
Breakdown for energy consumption :

Heating 2042.29 Kwh / year
Cooling 41049 Kwh / year
Interior lighting 38140,84 Kwh / year
ventilation 139 712.05

These data are based on a Dynamic Thermal Simulation study phase design (improved inputs and ambitious assumptions)

More information :

the actual consumption differs from the theoretical consumption, we did not perform any dynamic thermal simulation in the execution phase, however we have energy meters communicated to a centralized technical management (see photos), they indicate a consumption (17 MWH) the building is not yet busy regularly, we can share the annual consumption at the end of 2019,
The actual energy production by the installed PV system measured on June 13, 2019 is: 45 MWH in 2421 hours since system startup. (to see the photo)

Envelope performance

More information :

Garden floor retaining wall: A 13 mm Placoplatre, 5 cm high density rock wool accompanied by a 1 cm layer of thermal insulation of mineral wool, 20 cm reinforced concrete covered with an extruded polystyrene insulation of 4 cm => U = 0.571 W / m2-K.

Exterior Garden floor: A 13 mm Placoplatre, 5 cm high density rockwool with a 1 cm air gap, covered with 20 cm reinforced concrete => U = 0.616 W / m2-K

Wall outside floor: Wall rammed from 80 to 100 cm, the option 80 cm was selected responding to the safeguards of the RTCM => U = 0.665 W / m2-K

- Low floor on solid ground: Concrete slab of 15 cm with // Extruded polystyrene thermal insulation of 4 cm U = 0.658 W / m2-K
- Intermediate floor: 10 cm polished concrete slab on a DAS 250 // a 60 cm plenum, and a 13 mm acoustic plasterboard U = 0.451 W / m2-K
- Roofing: bituminous waterproofing layer // 7 cm high density rock wool insulation // one layer of R12 insulating foam and 3 cm fir decking U = 0.338 W / m2-K U < 0.65 W / m2-K ✓

- Structural partition: 16 cm reinforced concrete U = 2,490 W / m2-K
- Non-structural partition Garden level (classroom separation): Two layers of 26 mm plasterboard separated by rockwool insulation in 5 cm rigid panel U = 0.653 W / m2-K
- Current non-structural partition: Two plaster plaster of 15 mm on a brick terracotta 6 holes of 7 cm. U = 1.630 W / m2-K
- Glass partition: Simple glazing Stadio extra clear with aluminum joinery without thermal break. U = 5.788 W / m2-K
- Curtain wall double glazing argon filling with aluminum joinery with thermal break: U = 1,4 * 0,95 + 4,719 * 0,05, Uw = 1,396 W / m2-K, U <3,30 W / m2 -K ✓ and FS = 0.34
