The view factor is an approximation of the quality of the view that an individual has at their workstation. So, if you’ve got a larger building with many workstations, this is probably not a great method to show quality views. The LEED Reference Guide includes further explanation for how to calculate the view factor for an individual workstation.
The ISO and CEN standards are simply alternatives for determining acceptable ranges for thermal comfort in the building. So, applying one of these standards instead of ASHRAE 55-2010 won’t change the monitoring strategy that you need to have in place. However, the alternative standards may be more familiar to international teams and therefore could make the implementation process go more smoothly.
Currently, tank-type toilets, tankless toilets (flush valves), water-using urinals, private lavatory faucets, and showerheads can be WaterSense labeled, so must be labeled for this prerequisite. Aerators and flow restrictors added to private lavatories or showers must also be WaterSense labeled. Non-water using flush fixtures (waterless urinals, composting toilets), and public lavatory faucets do not have be WaterSense labeled because no label currently exists for those fixture types.
Yes. Any fixture that can be labeled by WaterSense must have the label.
To meet the credit requirements as a CS project, you must either meet the specific requirements within your scope, or, if those measures are not within your scope, you can require the tenant to carry them out under a binding and signed lease agreement. For the official language on this, see page 15 of the LEED Reference Guide.
Yes, the pressure differential has been eliminated in LEED v4. See LEEDuser's guidance for more info.
Yes, you can still get credit for meeting the exemplary performance threshold after the design review is complete. As long as you haven’t maxed out your two exemplary performance points under this credit, you can still claim the EP point after the design review.
Yes, you can replace that credit with another one that did earn exemplary performance.
The credit prescribes the use of a 2% leakage rate in the calculations regardless of the actual leakage rate in experience over the performance period.
Yes, the calculation needs to account for all refrigerants within the building systems, including the pipe funs for a VRF system. For this reason, buildings with VRF systems rarely meet the credit requirements.
