[RE-wrenches] More Summer cooling

[Dana]

I moved away from the humidity [ to SW Colorado] and yes we open up at night
and close down during the day. 

 

OK how about a small chiller that cools the slab during the day. 

 

There are solar absorption chillers in the UL stage that I have heard about
[not seen or used] recently.

 

Thanks -

Hi Dana;

 

In-floor heating of a super insulated building is a great idea.  In-floor
cooling however, has some serious condensation problems and is not a good
idea. 

In earth Air duct systems can harbor mold and Legionaries' disease.

Here in Northern New Mexico we use adobes (lots of thermal mass) and open up
to the cool night air. When I lived through Texas summers, you either ponied
up for AC, went to your mountain home, or suffered.

You stated the first 2 steps: 

super insulate & increase thermal mass.

Next ?? : 

Reduce your cubic footage of air conditioned space.

Reduce east & west glazing

Grow overhanging deciduous trees on the East & West

Use Fans

Use some evaporative cooling if possible

Use small High efficiency AC units (Sanjo?)

Raise thermostat

Use geothermal heat pumps

Migrate?

I have always wanted to do a super insulated house design that had a large
central masonry mass or floor slab with heat tubing that you could cool in
the summer during the nighttime and solar heat in the winter with solar. Or
an earth tube air duct system that you could pull cool night air through
that would cool the slab. I built a Passive Annual Heat Storage home 16
years ago that kept the house at 68 F during the summer in western
Washington. I was very comfortable. Any thoughts ?
