1 WHAT A BUILDTOG IS 1 Updated A Passive House project by EURHONET, ANMA, LUWOGE consult and BASF Eurhonet Buildtog Common design Planning and consulting services Local adaptation Outcome

2 GLOBAL WARMING 3 background EUROPEAN ENERGY SAVING TARGETS UP TO % less energy consumption by increasing energy efficiency 20 % less consumption of fossile energy by use of renewable energy 20 % less CO 2 emissions NECESSARRY SUPPORT Installation of necessary processes to implement energy efficiency in refurbishment and new construction Transfer of knowhow about energy efficient constructions along the whole value chane Initialisation of high level technology and sustainable construction material

4 BUILDTOG (building together) 5 eurhonet Our companies have the same goals To build high energy performanced buildings on a large scale at a reasonable price, with similar 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?

6 BASF / LUWOGE CONSULT 7 buildtog - partner eco efficiency and sustainability World s leading chemical company Intelligent system solutions and high-value products for almost all industries More than 50 billion sales (2009) More than employees (2009) Housing company of BASF Pioneer in energy efficient and sustainable housing solutions Social mission - housing offer with low costs for energy housing units Consulting company, subsidiary of LUWOGE Specialized in energy and economy efficiency and sustainability Experience in cooperation with housing companies Founded in 2006 Team with 20 architects, engineers and economists

7 BUILDING CONCEPT 8 common design Structure Typology 3 rooms Dwelling duplex 2 rooms Dwelling duplex 2 rooms Dwelling duplex 3 rooms Dwelling duplex Design Energy (Passive House Standard) coldest annual temperature - 1,1 C - 6,6 C (it) - 12,3 C (fr, nl,uk, lu) - 17,7 C (de) - 23,3 C (se) - 28,8 C - 34,5 C - 40,0 C

8 BUILDING ENVELOPE 9 common design - goal 1: heating load under 10 W/m2 or heat demand under 15 KWh/m2a, goal 2: n 50 under 0,6 / h Construction elements Carcass Massive construction, concrete and/or masonry, insulation outside of construction to avoid thermal heat bridges. Groundslab Mat foundation, concrete basement, pressureresistent perimeter insulation, subbase, frostprotected base frame. Wall Concrete or masonry, outer wall insulation system, plaster or rear ventilated facade system. Window/door Certified Passive House windows/ doors (wood/ insulation, wood/ insulation/ aluminium or plastics/ insulation). Roof Concrete or wood/boarding, on top of roof insulation, rear ventilation, roof covering.

9 BUILDING SERVICES 10 common design - goal 3: primary energy demand under 120 KWh/m2a (including domestic eletricity) A. Central indirect heat supply B. Central direct hot water supply C. Central direct heat supply Centralized heat generation for hot water, ventilation and heating by district heating (bottom/up), burner or heat pump (up/down). Centralized or decentralized ventilation with heat recovery, heat preparation indirectly by heat exchanger, after heating individually, radiators optionally. Decentralized hot water generation, indirect supply by heat exchanger. Centralized heat generation for hot water by burner or heat pump, solar heat possible. Centralized or decentralized ventilation with heat recovery, individual heating by electricity. Central hot water generation, direct supply by storage. Centralized heat generation for hot water, ventilation and heating by district heating, burner or heat pump, solar heat possible. Centralized ventilation with heat recovery for basic heat, individual after heating possible. Central hot water generation, direct supply by buffer storage.

13 DECISION SUPPORT 14 local adaptation Finding the best material solution step by step in course of project (example wall insulation) decision I Basic evaluation 10% (energy performance level - u-value) II Preliminary design 15% (construction system - rate of insulation) III Design 10% (facade system - insulation system) IV Building application 5% (product certificate - application of insulation) V Construction Planning 15% (insulation material - kind of insulation) VI Call for tenders 10% (product specifications - quality of insulation) VII Award of contract 30% (product - selection of insulation product) VIII Implementation 5% (product control - use of insulation product) IX Documentation x* 100% (certification - confirmation of insulation product) KU - PUR panels: PUR Sarking KTF EPS Neopor KTF XPS Styrodur The goal is not to work on thousands of projects! It is to develop a methodology and help to manifest it in replication.
