	Above. Passive design doesn’t mean that user controls should be basic. If anything, the user controls need to be designed with even greater care so the occupants know precisely what button to press to get the desired effect. Automatic lighting controls often alienate building occupants when they turn on and off nonsensically. A lack of manual override can compound the problems. At Broadmeadows, lighting can be switched between automatic and manual control using very intuitive and well-labelled switches.		Above. Passive design doesn’t mean that user controls should be basic.

	Innovation can fall into one of two camps: that which fulfils a client’s craving need, or that which fulfills a designer’s craving desire. Satisfying both is quite rare, especially with ostensibly active green technologies that often create more management and maintenance than clients have been lead to expect.

	Broadmeadows is notable as it signals a major shift in Australian school design. The passive engineering is far more akin to UK design practice than traditional Australian engineering, which tends to air-condition or mechanically ventilate as a matter of course. Here, ventilation relies on a natural thermosyphon, where supply air, up to 40°C in summer, is drawn through the water-encased ducts and injected into the occupied space. Air rises through internal heat gains and wind-assistance to be exhausted at high level.		Broadmeadows is notable as it signals a major shift in Australian school design.

	Above. Fluorescent luminaires in recessed fittings or metal halide lamps in a pendant fitting would usually be appropriate for a high-bay sports hall of the kind provided at Broadmeadows. Instead, the architect opted for a Chinese-made Zhejiang LED Pendant fitting of 120 W (100 x 12 W LED arrays), around half the wattage of a conventional pendant lamp suitable for this context. The gross weight of the fitting, with a glass light deflector, is under 14 kg. The supplier quotes a life of 30,000 h, a luminous flux of 9,600 lm, and a beam angle of 130 degrees.		Above.

Innovation can fall into one of two camps: that which fulfils a client’s craving need, or that which fulfills a designer’s craving desire. Satisfying both is quite rare, especially with ostensibly active green technologies that often create more management and maintenance than clients have been lead to expect.

Innovation in passive engineering, on the other hand, can lead to far more robust fit-and-forget installations.

In June 2010, Delta T reported on the construction of Broadmeadows Primary School in Melbourne, Australia, where the architect (Now Achitecture) aimed to cool the school’s supply air by drawing it through water-encased foundations (‘Pooled Resource’, Delta T June 2010).
