Virtual Participation in COP 15

Event 1:
The long awaited UN Climate Change Conference in Copenhagen (COP 15) has finally begun.


Rising hopes for a meaningful outcome at the Copenhagen climate talks have received a further boost with the news that Barack Obama and Indian leader Manmohan Singh will attend the 192-nation conference in its vital last days.

If you, like me, would have liked to be there to follow the discussions and all the surrounding activity - there is a an offering that will be welcome: "virtual Participation in COP 15".

Progress:
The hand-over meeting is less than one day away and there is still work to be done, but nobody showed up today.


During the weekend I found out that there was a 10C increase in the "used air" that the ventilation system sends out of the house - when we mix the heated air and the fresh air before the aggregate (versus only sending cold fresh air into the aggregate = the baseline case).


Today I wanted to estimate how much energy we waste when we send out 500 m3 (per hour) of air with a temperature that is 10C higher than the baseline case. Pulling the volumetric heat capacity (VHC) for air from the table below - I found that the loss is equal to 1,8KW for 10C (or 180KW per 1C increase in the exhaust air). This value will of course be higher when the outside air falls below zero (because the 10C temperature difference will be higher).
