[BLDG-SIM] Part Load Efficiencies of Air Cooled Chillers

[Ian Doebber]

I'm looking to understand to obtain efficiency data based on part load and various condenser temperatures for two chilled water temperatures (45 F and 28 F) for an air cooled screw chiller.  I need this information to understand the energy consumption with an integrated TES system.

BLDG-SIM,

Recently, Kathy Bash of DMS Architects gave a presentation 
to BSUG titled "Architecture As a Second Language -- 
collaboration between architects and engineers" that I 
thought many of you would find interesting. I have posted a 
copy of the presentation at:

http://www.gard.com/ml/ASL.pdf

Below is Tom White's original posting about it. 

Please take a look at it and let me know what you think.

Thanks,

Jason

Greetings BSUGgers:

We have just posted the handout for Kathy Bash's BSUG 
presentation: "Architecture As a Second Language -- 
Effective collaboration between architects and engineers"  

To retrieve a copy, point your Internet browser to:

http://tech.groups.yahoo.com/group/BSUG/files/

and download the file under the 070718 - BSUG July 2007
folder.

You might find Kathy's presentation especially interesting.
A few highlights include:

- A graph of six variables showing Napoleon's march to 
Moscow and how the Grand Armée  of 500,000 soldiers was 
decimated piecemeal by the Russians and the winter before 
their return.  

- When a pie chart makes sense and a table can be 
invaluable.  

- A new take on the definitions of the standard 
construction phases of programming, SD, DD, and CD 
(reminiscent of Mike Hatten's integrated design language).  

- An overview of simplified design tools, like Google's 
SketchUp, and when they make sense to use.  

- There are three languages in a project: architect-speak, 
engineering-speak, and owner-speak. Owner-speak is the 
language of decision-making.  

- What if designing buildings were top-down instead of 
bottom up? Code is bottom-up: setting minimum threshold 
criteria. But top-down would be to set a standard or target 
for a sustainable design, then see whether you could meet 
or exceed the target.  

How are all these points related? You'll just have to get 
Kathy's presentation to find out.
