1 BUILDTOG BUILDING TOGETHER JEAN DENIS MEGE Project Director EURHONET JOHANN SOUVESTRE Engineer, Energy Efficiency & Construction BASF Certified Passive house planner IMMEUBLE COLLECTIF PASSIF Paris, December 10 th 2010 Our companies have the same goals To build, on a large scale, high energy performance buildings at a reasonable price, with similiar technical and architectural approaches in our different countries. Then, why not to build a building on a common basis and compare concretely our different approaches to achieve the same goal? (EURHONET) 1

3 LA CLAIRIERE DES PRINCIPES POURTANT BIEN SIMPLES Principe 0 : Définir le volume chauffé Principe 1 : Isolation Principe 2 : Etanchéité à l air Principe 3 : Valorisation des gains solaires Principe 4 : Gestion de la ventilation Principe 5 : Equipements techniques efficaces Principe 6 (éventuellement) : Energies renouvelables MAIS DE NOUVEAUX MODES OPERATOIRES A METTRE EN PLACE Importance du travail en équipe et non séquentiel Importance des détails d exécution Source : Maisons passives, A. Guerriat Importance du suivi de chantier par les thermiciens 3

23 EFFICIENCY ENERGETIC PERFORMANCE, CLIMATE AND LOCAL INFLUENCES PASSIVE HOUSE STANDARD Passive House Institute Darmstadt, Germany REGARDING TO THE FOLLOWING ASPECTS Minimizing of heat losses via transmission by insulating the building envelope. Insertion of high quality windows to accomplish a comfortable atmospheric environment. Airtight closure of the building envelope to avoid unintentional infiltration. Minimizing of heat losses by gasper supply through controlled ventilation with heat recovery. Use of inner and solar gains for basic heating of rooms. Transport of necessary warmth for heating by ventilation system only, if possible. A CERTIFIED PASSIVE HOUSE CAN BE BUILD 1.Relinquishment of conventional heating and cooling system by maximum heat demand of 15 kwh/m²a (technical need) 2.Requested airtightness of n 50 0,6/h (technical need) 3.Primary energy demand for heating, warm water, auxiliary current and electricity 120 kwh prim /m²a (Definition Passive House Institute Darmstadt, Germany) (Maximal transportation of heat by ventilation system limited by heat capacity of air and draught sensation) 23
