Traditional Australian houses
Raised timber floors, ventilated roof spaces, weatherboards or masonry and later service additions.
Post-war Australian housing
Brick veneer, tiled roofs, slab and raised-floor variants with limited insulation.
Air-conditioning transition era
Growing insulation and cooling use across varied climate zones.
Contemporary Australian homes
Tighter lightweight assemblies, complex glazing and climate-zone-specific energy provisions.
Historic cold-climate homes
Masonry basements, solid framing, plaster and successive heating-system upgrades.
Post-war Canadian homes
Basements, split levels, early vapour control and variable attic ventilation.
Tighter envelope era
Improved insulation and glazing with greater dependence on controlled ventilation.
High-performance era
Advanced air sealing, mechanical ventilation and highly insulated assemblies.
Historic European fabric
Solid masonry, timber floors, lime or mineral finishes and layered urban alterations.
Reconstruction and mass housing
Concrete, masonry infill, flat roofs and large apartment systems.
Insulation and window-upgrade era
Progressive insulation, sealed glazing and external facade systems.
High-performance European buildings
Airtight construction, mechanical ventilation and high-efficiency heating.
Traditional Nordic houses
Timber or masonry structures, ventilated foundations and later layered insulation upgrades.
Post-war Nordic housing
Rapid construction, vented attics, crawl spaces or early slabs and mechanical exhaust.
Energy-crisis construction
Heavier insulation, tighter envelopes and evolving vapour and ventilation practice.
Low-energy Nordic homes
Highly insulated, airtight assemblies with mechanical ventilation and complex service penetrations.
Early timber New Zealand homes
Raised timber floors, weatherboard cladding and simple roof forms.
Post-war New Zealand homes
Timber framing, fibre-cement or weatherboard cladding and limited insulation.
Complex-cladding transition era
More complex forms and changing cladding practice, requiring careful weathertightness interpretation.
Contemporary New Zealand homes
Drained cavities, improved insulation and evolving ventilation practice.
Traditional solid-wall buildings
Solid masonry, lime finishes, suspended timber floors and breathable material behaviour.
Early cavity-wall era
Cavity walls, suspended floors, tiled roofs and later heating upgrades.
Modernisation and retrofit era
Changing insulation standards, sealed windows and widespread central heating.
Contemporary UK & Irish homes
Tighter envelopes, engineered floors and increasingly complex ventilation strategies.
Pre-1940 traditional homes
Masonry foundations, balloon or platform-transition framing, plaster interiors and later layered alterations.
Post-war expansion
Rapid suburban construction, vented crawl spaces or basements, early insulation and ageing service systems.
Energy-transition homes
Increasing insulation and tighter windows, mixed mechanical systems and extensive renovation layering.
Contemporary code-era homes
More engineered assemblies, air conditioning, complex rooflines and tighter envelopes.
Historic masonry homes
Thick masonry, timber roofs, suspended floors in some regions and later service additions.
Post-war South African homes
Masonry walls, tiled roofs, slab floors and variable site drainage.
Modern suburban era
Expanded electrical loads, flat-roof details and mixed cooling systems.
Contemporary South African homes
More insulation, solar systems, complex waterproofing and efficient services.
