1. Context
The Air & Light House is a European call for projects launched in 2009 by VELUX "ModelHome 2020", to experiement new ways of designing the habitat of the future, with the experimental construction of a detached house destined to reach a positive energy balance (Active House) and a neutral environmental impact, focusing on the comfort of its inhabitants.
2. Feedback
This experimentation and its organisation was rich in lessons, since the project was open to professionals for 6 months then inhabited for a year by a family. this generated a real feedback and allowed us to validate major Active House principles.
This experimentation will let us replicate the concept on individual or collective habitats for a sustainable comfort that saves energy and resources while stressing on a reasoned bioclimatic design and recycling fatal energies.
Sustainable development approach of the project owner
The Air & Light House VELUX ® Model Home 2020 was designed in a bioclimatic approach to produce more energy than it consumes. This is meant to implement a concept developed by VELUX ®: integrate the construction of a house into a holistic approach to consider all the design parameters of a contemporary home with a low environmental footprint, to offer a "whole package" combining quality and comfort of life.Architectural description
ModelHome 2020 by VELUX:- Timber frame (wood and zinc on facades)
- Solar and photovoltaic panels
- Heat pump, double flow ventilation, WINDOWS MASTER system (autmated management of heating, ventilation and solar protection nees) with inner comfort, CO2 and lighting monitoring.
- Weather station that anticipates external factors.
- Instrumentation, monitoring and supervision of consumptions for a year off and during the inhabited period.
- Specifific ModelHome 2020 requirements focusing on comfort of life (daylight, indoor air quality, summer comfort) and energy savings for a Positive Energy Building level, domestic uses included.
- HQE approach, especially followed on this project, inspired by the tertiary buildings requirements.
- BBC (Low Consumption Buildings in France) approach followed
Results:
- A positive energy building on regulatory needs (heating, hot water, lighting, ventilation and distribution), covered domestic consumption to 69%
Thermal comfort of the living room in class 1-2 (very efficient to efficient) according to EN 15251
- Observation on a hot day (36°C outside): the temperature inside the hosue is 8°C colder than outside.
Building users opinion
The feedback by the PASTOUR family:
"The different seasons are not felt in the house, the house is cool but still bathed in light"
"In summer, we are immersed in the light without feeling hot in the house. "
"The management of the temperature room by room allowed to adapt to individual needs, for example Rayan prefered the temperature of the room is 18°C to sleep well at night. "

Reasons for participating in the competition(s)
NOMADE Architectes a développé avec une approche holistique un ‘Concept Home’, habitat contemporain à faible empreinte environnementale, alliant qualité et confort de vie.· Une maison de conception bioclimatique et contextualisée : s’adapte à son environnement, en tenant compte de l’orientation, des vues, de la luminosité.
· Un concept transposable : une forme adaptable à d’autres configurations urbaines, par une composition en trois volumes de base modulables.
· Une cinquième façade active : le toit devient la « cinquième façade » par une optimisation des pentes commesurfaces de captage solaires.
· Une maison autosuffisante et responsable : conçue afin de produire plus d’énergie qu’elle n’en consomme, par une attention particulière portée à la qualité de l’enveloppe et à sa perméabilité, au choix des matériaux retenus pour leur faible impact environnemental, à l’orientation des ouvertures, à la ventilation naturelle et aux systèmes de production d’énergie (capteurs solaires et cellules photovoltaïques intégrés aux toitures pour la production d’eau chaude et d’électricité, pompe à chaleur pour le chauffage, ventilation double flux et système domotique pour le pilotage de la ventilation, du chauffage et des apports solaires).
· Une maison ouverte sur le ciel : L’ensemble des pièces disposent d’un apport de lumière naturelle abondant mais maîtrisé afin de ne pas produire de surchauffe en été.
· Une maison aérée et saine : La volumétrie générale associée à la disposition des ouvertures en façade et en toiture créé une convection naturelle qui favorise la ventilation naturelle.
· Une maison à géométrie variable : cette maison peut évoluer dans son enveloppe intérieure, avec notamment la possibilité de transformer la mezzanine ‘pièce en plus’ ou par l’ajout de modules.
· Une maison moderne : gestion domotique du chauffage, de la ventilation et de la luminosité naturelle. Ce système pilote automatiquement l’ouverture ou la fermeture des fenêtres, des volets et du chauffage, en fonction de l’ambiance intérieure recherchée et des conditions climatiques.
