Provide additional outdoor air ventilation to improve indoor air quality for improved occupant comfort, well-being and productivity.
For Mechanically Ventilated Spaces:
- Increase outdoor air ventilation rates to all occupied spaces by at least 30% above the minimum required by ASHRAE 62.1-2004.
For Naturally Ventilated Spaces:
- Design natural ventilation systems for occupied spaces to meet the recommendations set forth in the “Good Practice Guide 237: Natural ventilation in non-domestic buildings” (1998). Determine that natural ventilation is an effective strategy for the project by following the ﬂow diagram process shown in Figure 2.8 of the CIBSE Applications Manual 10: 2005, “Natural ventilation in non-domestic buildings.”
- Use diagrams and calculations to show that the design of the natural ventilation systems meets the recommendations set forth in the CIBSE Applications Manual 10: 2005, “Natural ventilation in nondomestic buildings.”
- Use a macroscopic, multi-zone, analytic model to predict that room-by-room airflows will effectively naturally ventilate at least 90% of occupied spaces.
