Hello! I am constructing a building model which spaces are half offices, half laboratories. The HVAC system chosen is system 5 (packaged VAV with reheat) for all building, since it is considered a

Hello, I have a question regarding equivalent standards : Is there an USGBC approved equivalent standard for projects located in France ? Many thanks in advance for your assistance.

The LEED v4 Reference Guide offers three was of determining equipment efficiencies, distribution losses, and distribution pumping energy: Monitored data, engineering analysis, and default values.

Hi everyone, Reading the v4 reference guide, it seems that the default process energy being 25% of total energy cost for the baseline disappeared from the requirements. Have you also noticed it?

In the building there is an electric transformer that transforms the electricity coming from the grid into low voltage energy. The transformer is particularly efficient.

Can you take credit for occupancy sensors that control HVAC systems? I am thinking probably not for system operation E.g setbacks, agree? But I am unsure for the ventilation.

We have a Green Building Council in Australia that has a very advanced energy simulation methodology that achieves the same outcomes as the ASHRAE 90.1 process outlined in LEED.

Hi all, Could anyone clarify if Ireland is in climate zone 5A or 5C? Thanks in advance

Does anyone know wether or not evaporator input power should be included in the efficiency calculation of a VRF system?

Exception c requires that lab spaces use a system 5 or 7 in the same way that exception d does, but exception c does not prescribe any specific turn down during unoccupied periods.
