Point: 4.4.1 Does the wording "It should also be noted that a net photovoltaic yield NPVE can be calculated in accordance with EN 15316-4-6, subject to the condition that the total electricity demand per month of the building may not be exceeded by the NPVE invoiced and added to the balance (i.e. grid feed-in may not be used to reduce the final energy demand)" mean that, in the case of a residential building, the NPVE to be determined on a monthly basis may not exceed the value of the monthly household electricity consumption? - Österreichisches Institut für Bautechnik | OIB

The passage “Grid feed-ins may not be used to reduce the final energy demand” means that yields may only be balanced to reduce demand if a demand occurs at the same time! Until standardized load profiles are available, the existing loads may be distributed evenly over the times of use.
