A self contained guide to all aspects of cleanroom design, construction, testing and operation. Also examines cleanroom clothing requirements, as well as practical advice on the cleaning of cleanroom facilities. Supplemented by information on the latest sources, recommended practices, journals, books and internet sites.
Reports on the detailed design of Birchensale Middle School, and how the design team has incorporated PROBE lessons into the specification. The school is over 30 years old, naturally ventilated and lightweight in construction. The PROBE team's role has been to help fine-tune the design based on the findings from PROBE post-occupancy studies. Perimeter classrooms are naturally ventilated with cross-ventilation via openable fanlights above the classroom doors.
This article concentrates on displacement ventilation design procedures appropriate for rooms with heat- and contaminant-removal requirements. With passive thermal displacement ventilation, supply air is discharged directly into the occupied zone at a low velocity near the floor level and at a slightly cooler temperature than the design room temperature. The air from the diffusers spreads along the floor, creating a relatively cool layer of fresh air near the floor.
Describes how methods used in widespread energy efficient residential buildings in Germany are now being applied to larger buildings. Germany's Passiv Haus Institut has become a leading centre in developing a specification for the next generation of energy efficient buildings - the Passive House Standard. In 400 residential building the standard has reduced total energy consumption to 12% of the UK norm. Describes how this approach has been applied to a 2,200 m2 office and factory in Colbe, Marburg. The three-storey structure was completed in autumn 1998.
