Hello, we are working on a project LEED C&S in 2009 of approximately 100,000 square feet. The property doesn't want to implement the energy modeling due to economic issues. Since the project is

The project team has specified a centrifugal chiller of over 600 Tons with a nonstandard conditions. It has been sent an AHRI certificate showing the compliance with ASHREA 90.1-2007 and 2010.

How do you account for the difference in service hot water efficiency from the proposed design to the baseline design if the proposed design is using electric point-of-use water heaters?

We have a project that use heat recovery chiller to recovery heat from the waste heat from a nearby data center.

We are creating a Revit model using Revit 2014. Going for LEED2009, (ASHRAE 90.1-2007). Do we need two models? Thinking of bringing model into eQUEST. Is that necessary to determine baseline vs.

Our project is a major renovation project. Do the ASHRAE mandatory provisions apply to existing systems/components that are not altered?

Our office building (Major Renovation v3 2009), located at 3C climatic zone, doesn’t exceed 25,000 ft2 of conditioned floor area, but has more than one floor. Different users will have their own s

Appendix G does not address humidity controls.

Hi, I am trying to classify an HVAC System (for the Baseline model) of 3731 m2 distribuited on 6 conditioned floors (HealthCare facilities). Checking the Table G3.1.A (Ashrae 90.1-2007) apparentl

i m using HAP 4.41 for HVAC load calculation and energy modeling but unfortunatly the weather data available is hourly average s it ok to use for leed energy simulation or i ahve to go to another f
