13 How did you reconcile opening to the environment when there are such temperature variations? Left and above The floating roof on the north elevation permits deep winter sun penetration with little need for artificial day-lighting during any season. The house when required, is quite porous. It’s all about openings and accessibility. The coastal climate here can be quite extreme with high winds, so the design and build had to be fully water and airtight. The biggest challenge was that the clients enjoy a sense of opening to the sea and use of the decks, yet the house needs to hunker down at other times. Passive ventilation occurs through roof vents and optimal windows to create air movement. The big driver was creating a warm thermal envelope that would pick up solar gains in winter and manage those extremes of thermal gain across the seasons. Use of Viridian’s double-glazed units incorporating ComfortPlusTM are brilliant in achieving that.
