Hi,
Does anyone know if there are any extra requirements aside from the optional BECx in LEED for HC vs Canada NC 2009? I can't see any but have been told there are more visits required. Am I missing something?
Thank you!

Shevaun,
I'm not aware of how the Canadian version of NC is written but the US version of NC has no requirement for building envelope commissioning. In HC, there is one point for BECx and one point for ECx. The Enhanced portion of HC is the same activities as the NC version minus a point value for the same amount of work. For building shell Cx, the HC version requires you to follow the NIBS guideline which is easy to obtain online. How many visits this requires is dependent on the different types of building envelope a project has.
I'm not sure if I answered your question.

Thank you Susan, I can't find any differences between Canada NC 2009 & US LEED for HC requirements for HVAC/energy/lighting systems enhanced Cx, so I think they are the same. I'm going to have one more read through the credits and call it even.

My only advice for MEP commissioning in hospitals is to do what is right for the facility in addition to meeting LEED. You'll want to commission life safety and emergency systems in hospitals. Your owner may require additional systems to be commissioned.

Susan, I could not agree more. There are several systems that are critical in a healthcare environment that should be tested. One major test we recommend is the blackout test…it is vital that this works right when patients are in the building, and it can only really be done when the building is not occupied.

Yes, in addition to LEED requirements our hospital facility services often include Cxing the electrical, IMIT, communications and security systems, elevators, med.gas and equipment; coordinating and witnessing full building systems integration verifications; and coordinating and witnessing multiple post-occupancy 'doomsday' testing scenarios. Some educational facilities are beginning to request commissioning of these other systems as well.
