New Orleans is havin' a heat wave

Aditi and I really can't complain when we see the weather forecast for the New England, but the weather here in New Orleans has been HOT!  We'll use this as an excuse for not posting all of last week.  

Of course, anytime temperatures get this high, the power grid struggles to keep up.  I am pretty sure our neighborhood experienced a bit of brownout last night, when power was cut for around 10 minutes.  (At least, I am being generous to Entergy New Orleans by giving the power cut a demand side reason.) One the most important aspects of investing in Energy Efficiency is helping municipalities to reduce the peak power pull.  If New Orleans made a serious commitment to weatherizing its homes and right-sizing the air conditioner units I would have been spared the 10 minutes of absolute horror that I might have to try to sleep through a night of 87 degrees and high humidity without air conditioning.

An excellent way to weatherize a home in New Orleans is using Thermal Coupling.  This technique reduces the moisture exchange with the ground -  a major problem in humid sections of the country.  This allows homeowners to set their thermostats higher on these hot days because A/C really serves two purposes - cooling and dehumidifying.  By reducing the need to dehumidify, a home can significantly reduce the amount of coolant required to maintain a comfortable interior temperature.

All of this ran through my head when the power cut at 1am.
