The purpose of Clerestory windows is to:

An ideal insulation material has a high R value which means the transfer of heat through the material is slow.  The inverse is known as the U value and is a measure of how well a material conducts heat.

Eaves are a very simply design feature on buildings that allow solar radiation to come in through windows when the sun is low in the sky in winter, but shade the windows when the sun is high in the sky in summer time.  Modern homes often don't have eaves and rely on fossil fuels to heat and cool the building instead which is really stupid.

The gold standard heat exchange equipment incorporates a heat pump so that (consider the winter case):

A heat pump uses compression and expansion of a gas to move heat from inside a building to the outside (cooling mode) or from outside a building to the inside (heating mode).  A typical heat pump will use one unit of electricity and move 4 units of heat.  This ratio is known as: 

Gillies Hall at the Monash Peninsula campus has achieved:

Low emissivity glass can be achieved by adding an extremely thin layer of silver, stainless steel or titanium to glass via a vacuum deposition process similar to that used in making thin film photovoltaics.  The film on the glass:

If you are in the Southern hemisphere, which is the preferred side of the building to have the windows?

A G-value of 0.6 means that:

In Rob's slides he show results for pressure tests with some houses showing air flows rates of 30 air changes per hour at 50Pa conditions.  This kind of house could be described as:
