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
