I am working on a project that consists of an existing building which will be retrofitted and modeled as a major renovation under LEED BD+C.

Utility rates is a confusing thing for me, I am working on a building that has 9% Retail Area, 7% Church and the rest is a Residential Area.

Hi, 90.1-2007 confuses me a little. Our project (4 story, 9000 m²/90000 ft²) is located in climate zone 1b. The proposed building is heated by an electrical heatpump.

I've gone through the threads and can't find a response for a question like this, there must be one, but we have a theater project with all of the speciality lighting associated with this use.

ASHRAE's table G3.1, section 5(a), states the baseline model should not shade itself.

Hi, I have a question about the interpretation of section G3.1.3.13 (VAV minimum flow setpoints).

I've been trying to understand how does LEED treat kitchen exhaust hoods with make up unit(heating only) in the energy model. Is it process or non-process?

Anyone knows what energy modeling software has developed South America weather data?
