LONDON - AS OF 2013 • New residential in UK required to meet zero carbon standards. • To comply, a new scheme must achieve a 44% reduction on the carbon emissions rate over a target notional building of the same size, shape and area.
Aim: To future-proof the energy efficiency of dwellings over their whole life by limiting heat losses across the building envelope. Impact: Increasingly difficult for traditional curtain wall design to comply with code and meet market demands. HISTORIC LANDMARK

RESIDENTIAL CODE COMPLIANCE
TO COMPLY WITH CODE (SAP):
is pushing standard curtainwall design to the limit MINIMIZE GLAZING, EXCEPT SOUTH FACING Performance Criteria he Standard Assessment T Procedure (SAP):
MAXIMIZE OPAQUE INSULATED VERTICALS
The focus on cladding compliance becomes: • heat loss; and • air tightness with the average U-value of the wall targeted at 1.0W/m²K (metric).
X MAXIMIZE INSULATED SPANDREL
MINIMIZE THE NUMBER OF MULLIONS
RESIDENTIAL CODE COMPLIANCE is pushing standard curtainwall design to the limit
Contradicting Criteria Daylighting requirements generate wider glazed panels.
TO SATISFY DAYLIGHTING, VENTILATION AND DEVELOPERS: MAXIMIZE MINIMIZE GLAZING WIDTH MINIMIZE MAXIMIZE OPAQUE INSULATED VERTICALS
Market drivers generate: • floor to ceiling glazing for views; and • reduced depth of insulation to maximise area Ventilation requirements generate operable windows, introducing more mullions and transoms.
MAXIMIZE INSULATED SPANDREL BUT AVOID SILLS OPERABLE PANELS MEAN ADDITIONAL MULLIONS MINIMIZE THE NUMBER OF MULLIONS

RESIDENTIAL CODE COMPLIANCE Utilizing larger unitized panels to improve thermal performance
Benefits • Reduce mullions and panel to panel joints - the worst performing parts of the curtainwall • Avoid triple glazing • Integrate precast into unitized panel • Avoid dependence on the tower crane by using a monorail

Secondary Benefit • The use of prefabricated pods is increasing the demand for floorspace during construction • Installing larger facade panels from the ground creates floorspace
