Urban environment

• Land plot area : 630,00 m²
• Built-up area : 15,00 %

To meet the criteria of environmental, societal and urban requirement of the project, the research field of the future house is oriented areas under Layouts in Ile-de-France. The choice involves a subdivision incorporating specific characteristics to an eco-neighborhood: Parc des Justices on the common Verrieres-le-Buisson (91). The houses in this subdivision are particularly common in the use of the principles of construction and ecological design, while respecting the diversity of styles and architectures, in this city where half the area is wooded.

Indoor Air quality

Categories 1 to 2 according to EN 15251 in all parts of the house

Comfort

Health & comfort : In the design stage of the Air & Light house, certain aspects were specifically attended to:
a. Daylight
Different daylighting simulations were performed to optimize positioning and sizing of vertical windows and roof windows. The goal was to obtain a daylight factor greater or equal to 5% in the living rooms, so as to maximise the well-being of residents and impact down the consumptions of artificial lightings. Ultimately, the glass windows ratio compared to the living surface reaches 33% (or 2 times the regulatory minimum requirements of 1/6 of glassed bays edicted by the French RT2012)
Attached, natural lighting final analysis done with the VELUX Daylight Visualizer software.

b) Summer comfort
The Air and Light house benefitted from a thermal comfort strategy and particularly summer comfort, right from the design stage:
Structural aspects
- High concrete floor to increase inertia (the hosue is timber framed)
- Awining in the south, to protect the terrace and all the southern windows.
- Strategic positioning of roof windows to exploit the natural thermal draft and crossed natural ventilation
- For roof windows: use of double glazed windows with solar control.
*Active systems
- Automated management of openings (motorized skylights façade, roof windows motorized roof) according to the indoor and outdoor temperature levels (probes) optimization of night cooling in summer - automatic closing roof windows when it rains (Detector Integrated rain to motorized skylights).
- Automated management of external sunscreens according to the outside temperature and solar radiation.

c) Indoor Air Quality:
* Harmlessness Cage materials
 - Choice of materials classified A +
 - Plasterboard Using Activ'Air® Technology (Placo): active ingredient which captures VOCs, converts to inert species, and thus protecting against the rebroadcasting of pollutants.
* Systems:
Establishment of a hybrid ventilation combining the advantages of the double flow mechanical ventilation and natural ventilation by opening windows seasonally. In both cases, the air change is managed according to the level of CO2 and humidity in each room of the house.

• In testing phase by the family who lived in the house for a year:
a) quantitative monitoring of energy consumption, water, energy production (photovoltaic tiles) and also rational indicators of comfort:
* Outside temperature (weather station)
* Internal temperature in each room
* CO2 and humidity rate in every room
b) Monitoring of quality life experience of the family for a year
* Blog run by family
* Monitoring conducted by the sociological sociologist Monique Eleb.
Monique Eleb, researcher and member of ACS Laboratory the National School of Architecture Paris-Malaquais.

• Feedback:
Following this comprehensive approach for monitoring and tracking the life experience, the key points of feedback are:
a) positive energy balance: consumption of regulatory positions in line with forecasts
b) The key role of natural light
* Consumption of artificial lighting: reduced to 1.3 kWh ep / m².year!
* And especially on the health and well-being of the family - some excerpts from his blog:
"No more little bit of blues in autumn, it is the effect of light therapy home"
"A lot of natural light, has become a standard for our future home. When you go to another house, something is missing "
"In winter we light the light an hour later than our neighbors"
c) The satisfactory thermal comfort throughout the year including summer
d) Air quality regulated satisfactorily in the different rooms of the house.
Very positive testimony of the family: "The air is renewed, it's definitely metter up, forget about airing all the time and the air is really healthy. Health Rayan (11 years elder son) has improved, we would have never believed that he was asthmatic "
e) Automation and lifestyle:
One lesson is that the "all automatic" is not realistic. The possibility, as was the case in the house Air and Light, you can take control of the system is essential.
In parallel, the family could access in real time, thanks to a screen in the house, its water and energy consumption and energy production figures from home. Here are excerpts from his blog:
"We could see that on the screen of sunshine days ago SBIPS big production, it's great! "
"It is not binding, it is empowering. we will less run the water ... it's easy to put a sweater or less water the garden ... ".
This virtuous behavior had a direct effect on water consumption:
The average consumption of the family home Air and Light was 84 liters / day / person or - 44% compared to the average consumption of French.
