CBE Research on Ceiling Fans May Help Tackle Future Global Challenges

It’s exciting when we have the opportunity to experience new sustainable buildings first hand. Last week, while attending the CHESC conference at UC Santa Barbara, along with other attendees I stayed in newly completed student housing designed to meet LEED Platinum standards. While these attractive new buildings exhibit many sustainable features, at times the natural ventilation scheme was not sufficient to maintain comfortable conditions, especially when it was necessary to lower blinds for privacy, or to close windows to block noise from the street and some late night volleyball games.

However, a simple and cost-effective addition to these units would have kept us all comfortable: ceiling fans. CBE research has quantified what we all know intuitively, that fans can provide acceptable comfort at temperatures that otherwise would be stifling. This enables passive solutions in milder climates, and may reduce the reliance on air conditioning in climates where passive solutions alone are not sufficient.  Read more
