System distribution losses

 Go to the Extra energy and losses form

 Set hot water use

👉  You can change the units for hot water use

 Break the link for number of occupants calculation by defining 5 hot water consuming occupants for the whole building

 Select ‘Typical’ for all distribution system loss coefficients

👉  Alternatively set the distribution system by writing its coefficients in these text boxes

👉  Note that units can be changed for these

👉  Define what percentage of the lost energy that will enter into zone heat balances (the share of ducts and piping that pass through modeled zones)

👉  Define average plant losses (permanent loss, independent of operation)

👉  Define any additional energy, such as external lighting, ice melting equipment etc., that do not enter into the building heat balance

👉  Close the Extra energy losses form
