A Dwelling ProjectGallions Ecopark, London
Environmental design in practice
Gallions Ecopark Objectives
Demonstrate replicable sustainable homes for social housing
Pragmatic and convincing concepts, based on Dutch examples
Dutch architecture in UK contextJan Splinter Architects - Netherlands
From concept to reality
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
Ecopark Concepts
A > small houses, passive solar + sunspaces at entrance façadeB > single family houses, underfloor heating and heat recoveryC > large single family houses, passive solar + sunspaces, preheatingD > single family houses, rainwater harvesting, natural ventilation

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
