Historic Preservation Commission <br />President's Report - May V th, 2011 <br />• 04/18/2011 7:00-8:30P: HPC Monthly Meeting (Rm 1308). <br />• 04/30/2011 11:00-2:30P: Attended Energy Audit #2 demonstration by Ron <br />Zmyslo at 1012 Riverside Drive (the Michael & Gabrielle Keen residence). HPC <br />attendees: Elicia Feasel, Wayne Doolittle, and Michael Voll. Test and discuss <br />building science concepts - i.e. convection and the stack effect. Original <br />workshop in 2010 (612 Portage Avenue) did not produce blower test data due to <br />excessively high leaks in the building envelope. Today's test was challenged by <br />occasional, strong wind gust. But with delicate compensation, data points were <br />finally recorded and will be available for review. Findings reinforce the theory <br />that excessive energy loss (heat) does not occur through window and door <br />openings, drafts enter the structure from the lowest level of windows (basement) <br />and what might typically feel like drafts around upper story windows is actually <br />air evacuation. Also "comfort" problems (cold areas around window/door <br />openings) do not necessarily represent energy loss. <br />• 05/16/2011 Repair HPC Micro cassette Transcriber/Dictator Model #BM -850. <br />Install new coupler jack (D -Sub connector), solder patch cord to pc board, add <br />servo boss pins for broken mount. It works! <br />
