I am working on a project that, through a series of contract issues during construction, does not have commissioning documents for the PV array.

For HVAC Background Noise, do all spaces have to use the same Sound Rating Method (NC/RC, dBA,
dBC, RC(N)), or can these vary by individual space or by space type?

Hi

My proposed building has a number of unconditioned spaces (per definition according to Appendix G):

For the prerequisite, can we obtain it, if we only achieve improvements on one of our indicators (Cost or GHG emissions)? e.g. -9.4% for Cost and +14.4% for GHG Emissions

Has anyone been able to tackle the third option for this credit, which is not shown in the BPDO calculator?

Has a 90.1-2010 AEDG been published yet or is 2004 the most recent? Thanks

The Prerequisite is pretty explicit that it only applies to newly installed fixtures. What happens if the ice machines are existing?

What method of testing have people used to measure airborne PM-10 dust required as part of V4 IEQ Credit 3.2?

Is real time monitoring acceptable?

In this reconfiguration of the credit, it's a bit ambiguous in its requirement for nature, urban landmarks or art.

Hi All,
