NC-2009 EAp2:Minimum Energy Performance

30% fresh air allowance over minimum requirements of ASHRAE Standard 62.1

I strongly question this application of minimum 30% more fresh above ASHRAE Standard 62.1 for buildings in hot and humid climates like Colombo in Sri Lanka where designers on specific project insist on having this additional 30% of fresh air. 

I would appreciate comments in this subject.

Precisely why this credit is optional. It should be agreed by all the stakeholders, not blindly applied to every project. The manual makes it very clear that this credit in particular involves trade-offs (including increasing energy use) and may not be ideal for every project. If your LEED consultant is insisting on this then ask why-- if it is just for accumulation of points then there may be a better way to get to that goal. I hope that helps!

The tradeoff is usually for an improvement in indoor air quality. There are studies that show that more fresh air can provide some benefits to the inhabitants. So I agree with Melissa you need to find out why they would like to do this.
