GREENWICH ROYAL OBSERVATORY

• 75 residential buildings over 20 storeys under construction

• Additional 145 are approved

PALACE OF WESTMINSTER

• 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.

• air tightness

Daylighting requirements generate wider glazed panels.

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.

Contradicting Criteria

MAXIMIZE INSULATED SPANDREL

TO SATISFY DAYLIGHTING, VENTILATION AND DEVELOPERS:

• Triple glazing difficult to avoid

• Insulated mullions

• Depth of units increased to accommodate thicker insulation

• Minimum number of operable windows

• Potential overheating - as not enough ventilation

RESIDENTIAL CODE COMPLIANCE

• 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

Utilizing larger unitized panels to improve thermal performance

Benefits

RESIDENTIAL CODE COMPLIANCE

• The use of prefabricated pods is increasing the demand for floorspace during construction

• Installing larger facade panels from the ground creates floorspace
