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