Tale of Two Windows

A comparison of two window assemblies, one the original wood windows, the other a vinyl replacement window, seek to determine if the perceived thermal efficiency of the vinyl replacement window are actually realized. Components bottom and side sash components were analyzed to determine the extent of the thermal bridging between the inside and outside of the two assemblies as well as rudimentary infiltration analysis.

Temperatures in the Sunspace at Gerlinger Hall

This case study looks at the temperature influxes within the South-facing hallway of Gerlinger Hall, a historic building from 1921, on the University of Oregon campus. Large windows along the south side creates a grand sunspace. This sunspace is a popular place for students to study and relax, even while the temperature is out of comfort range. We investigated sources of heat loss and movement of heat through the section of the hallway. We discovered that solar heat gain was as much of (if not more of )a problem in the space than was heat loss.

Price of Printing

This case study looks at levels of ammonia hydroxide and whether they exceed air quality standards in a printing area of an architecture office in Eugene, Oregon. The office is an open- plan drafting room adjacent to a printing room where the printing machine is located. The room does not have any mechanical ventilation. Occupational Health and Safety representatives assisted us in determining ammonia levels.
