Magazine Notes

• ASHRAE Journal - you can only access the current issue at their Web Site but you can sort of access the article online by gaming their on-line magazine browser. it appears to go back to March 2006. (junk email & Ash!####)
• Sustainable Facility previously known as Energy User News. Old archives Before Sept 2007 and New Archives
• Engineered Systems with archives back to June of 1999. You have to register but it's free and not difficult. (junk email & Esy!####) They also have a Blog but it doesn't seem to be up active.
• Heating Piping & Air Conditioning- HPAC nice archive all the away back to January 1992.
• Archietectural Lighting Online- devoted to lighting mostly high end fancy lighting with great photography in the issues. Archives go back to November 2006. It appears you can search for older articles.

Weather Report

A monthly Engineered Systems column that has some great information about using weather data to estimate loads and savings. Unfortunately it doesn't appear archived- at least I can't find it. By Michael Kjelgaard, P.E. Engineering Weather Data

• Heat Recovery Systems. March 2004
• Pushing Economizer Cooling To The Limit. July 2004
• Sensible Loads. August 2004
• Ventilation Load Analyzer. September 2004
• Economizer Savings. November 2004

HVAC Commercial

Estimating Demand & Efficiency

Score Sheet for HVAC System Efficiency: Nice spreadsheet for estimating overall efficiency of a commercial HVAC system. It covers 7 system elements: Chiller/Compressor, Supply Air Handling Unit, Return Fan Pressure, Chilled Water Pump Head, Condenser Pump Head, Cooling Tower or Condenser Fan, Zone or VAV Terminal Fans.

The program/ spreadsheet is available at www.geokiss.com (not online anymore? Try Google and Archive.org. ) Ground Source Heat Pump Design: Keep It Simple & Solid

ASHRAE Journal, July 2003, p36
