[esp-r] Re: Dynamic Insulation

Cormac,

You may wish to look up my MSc dissertation (on the same subject) at the ESRU website. Interestingly I did this work with M Imbabi of Aberdeen University. I used an approximate method using thin zones. There is potential in extending the work using a better (first principles) approach.

Regards,
Aizaz Samuel

Hi Cormac,

We can better answer your question if you provide more detail on your research:

 *
What do you hope to learn from modelling this technology?
 *
How is the envelope constructed?
 *
What pathway will airflow take through the wall?
 *
What magnitude of air flow do you expect through the wall—is it the same order of magnitude as the ventilation load, or many orders smaller?

Subject: [esp-r] Dynamic Insulation

 I am trying to create a construction material and composition which includes an air permeable material,
to use as a dynamic insulation to simulate a "breathing building" construction for my Thesis.

How should i go about setting this up, as energy and materials technology are not my general area of study.

also, when setting up control loops, am i right in saying that for a basic heat/cool control,
the applied heat energy in watts is the amount applied per time step? ie, per hour?

thank you,
Cormac Walsh
