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:  

Going to the extra effort to make a building airtight has which advantage(s)?

According to Rob's lecture what is the death of most buildings?

Consider a house with tradition halogen bulbs for lighting.  Each bulb consumes 50W.  Assume all the energy in converted to heat.  If there are 30 bulbs running, but these are substituted with 9 W LED lights, how many less Watts will be emitted into the house?

Keeping buildings cool is more of a challenge than keeping buildings warm because buildings have a range of appliances (TVs, fridges, kitchen equipment, lighting) and people that emit heat.

Conduction, convection and radiation are best described by (in order):

Loosing heat via evaporation uses which for of heat transfer?
