Wurster Hall Public Lighting Report (Revised)

December 8th, 2010 by alexander.petuskey

After further consideration about the topic of Wurster Hall’s Public Hallway Lighting, several changes were made to the previous report posted on WordPress. A few new content inclusions and revised survey charts are among some of the most notable changes. Additional energy reduction analysis was also performed in the event that all atrium lighting was equipped with daylight senors. Hopefully some of the suggestions and conclusions from this report will result in future action to further reduce Wurster’s electricity demand by retrofitting public lighting. The new report is posted below:

Submetering group report and presentation

December 6th, 2010 by dheinzerling

The report and presentation for the submetering group are available below as PDFs.  Despite not having access to submetered data in time, there are a few interesting conclusions to be drawn.  We will be keeping our eye on the meters to see how some of our predictions pan out.

VFD Group – Paper and Presentation

December 4th, 2010 by kcsolheim

Our group was tasked with evaluating whether Wurster Hall’s ventilation system could become more energy efficient without creating a code violation or sacrificing occupant comfort. With variable speed drives installed on exhaust and supply fans throughout the building, we capitalized on our opportunity to collaborate with Eli Perszyk and attempt to tune these drives while also measuring the efficacy of outdoor air delivery in a mixed-mode building.

Wurster Public Lighting

November 30th, 2010 by JessicaJones

In recent years Wurster Hall has undergone a light fixture retrofit for the purposes of running a more energy efficient building and reducing long-term costs.  The following study examines the possibility of delamping retrofit fixtures as a mean to reduce Wurster energy use.  The study involved looking at the effects of the lighting retrofit by observing and measuring existing lighting illuminance levels in public areas, specifically major corridors of floors one through three, and comparing the findings to the recommended amount for lighting hallways by the Illuminating Engineering Society of North America (IESNA).  The gathered data determined whether or not delamping would provide sufficient lighting without compromising occupancy comfort and safety during the day and night.

Diggin’ into Wurster’s Plug Loads

November 19th, 2010 by erichi

Using plug load data that Austin painstakingly and altruistically collected, I took a crack at estimated how much energy consumption these loads might be responsible for (by appliance, of course).  The results were illuminating:

Public Area Lighting Update

November 16th, 2010 by alexander.petuskey

The public lighting group has analyzed two sections in Wurster that we recommend would be good tests sites for de-lamping. Below is a PDF of the locations where the lighting measurements were taken and their lighting values during night, day, and influence of day light. We took measurements in the center of 3 feet x 3 feet regions in order to map the influence of lighting throughout all portions of the hallway. The measurements were taken 30 inches from the ground. The recommended hallway lighting values are 5-10 foot candles as outlines by . Most of the 1st Floor section was not measured during the day since it is well removed from day lighting sources. For more goodies, read the rest of the entry .

Hallway Lights

November 9th, 2010 by JessicaJones

This past week we have been taking illuminance readings of selected areas of the hallways.  We are focusing on an undaylit area on the first floor and a daylit area on the second floor.  Our goal is to show that these areas are overlit and partially delamp some of the fixtures (with Cris’s help).  The PDFs show the readings taken at night, during the day and the influence the daylight has on the area.
