ventilation, gains) and contructions data (layers, surfaces, windows) 
and schedules

· Use of longer names of airnodes and zones, construction types, etc. 
possible

· Use of small letters for names of airnodes and zones, construction 
types, etc. possible

· Rename wall types to construction types

·  Updated glazing library

·  New schedule library

·  Added annual schedules

·  Added new gain library

·  New gain categories: lights, people, equipment, misc, thermal bridge

·  Reference area as a new parameter for each airnode

·  Area related definition of regime data types (heating, cooling, 
ventilation, gains) possible

·  Extended regime coupling of airnodes from 2 to 6

·  Added total renewable primary energy and total non-renewable primary 
energy for opaque layers and windows
