In 2003, the Heschong Mahone Group completed a second suite of major human performance studies on behalf of the California Energy Commission's Public Interest Energy Research (PIER) program. These include: a study of how skylighting effects the sales at a second chain retailer; how physical comfort conditions in classrooms are associated with student learning at Fresno Unified School District; and how windows and how physical comfort conditions are related to office worker performance at Sacramento Municipal Utility District offices. These new productivity studies consider the impact of daylight on human performance, along with other aspects of the indoor environment such as ventilation and view.

For the Pacific Gas and Electric Company in 1999, we studied the correlation between daylight availability and human productivity. The study was done in two parts. One part looked at elementary student test scores in three school districts. The second part looked at retail sales in a chain of 100+ similar stores.
