1. Chiel Boonstra A Dwelling Project Gallions Ecopark, London Environmental design in practice

2. Gallions Ecopark Objectives Demonstrate replicable sustainable homes for social housing Pragmatic and convincing concepts, based on Dutch examples Dutch architecture in UK context Jan Splinter Architects - Netherlands

3. From concept to reality

4. Environmental characteristics Strong architecture / timber frame Good insulation (U = 0,25 W/m2K) Advanced glazing (U = 1.1) Individual condensing gas boilers Low temperature heating Solar thermal collectors for DHW facade cladding: Slates Solar design Ventilation strategies Water efficient showers + taps, rainwater butts

5. Ecopark Concepts A > small houses, passive solar + sunspaces at entrance façade B > single family houses, underfloor heating and heat recovery C > large single family houses, passive solar + sunspaces, preheating D > single family houses, rainwater harvesting, natural ventilation

6. Ecopark in Gallions Reach

8. Skylights

9. Roof integrated solar collectors

11. Underground waste storage

12. Differences UK - Netherlands -Fresh air supply systems - Decentralized exhaust ventilation - position of heating system - space use / attic - staircase - timber frame - acoustical insulation - commercial availability of sustainable materials - industrialisation, prefabrication - construction details - level of finishes

13. Energy + comfort monitoring
