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

Hi All, I'm working on a project building with double skin facade, and this double skin facade system is equipped with an automatic shading device in the cavity space between the glazings.

I'm working on a science building on a prep school campus with a lot of lab space. It was entered as a school into Target Finder, but obviously compares poorly to regular school buildings.

Hallo Marcus, I am doing a WBS for an office building, which cooling is supplied by ground water. The only energy consumption of ground water cooling is the energy need for the water pumps. The e

Dear All, For modelling pumps for my Proposed design, I have a manufacturer's datasheet for a Variable speed pump (Secondary pump) with the following values: Duty Flow = 209.5 gpm Du
