# Introduction The heat loss caused by the transmission of a room is the sum of all heat flows through the room limiting surfaces. This means walls, floor, ceiling, windows and doors. The room-limiting components can be adjacent to differently-controlled rooms or environments. For this reason, these have different heat flows arise between the adjoining surface areas. These also have different heat flows on the adjoining wall surfaces. The heat flows can occur both positively (heat loss to the neighboring room) and negative (heat gain from the neighboring room). A key fact for getting the right result of heat loss (room) calculation is to know, which temperature the considered room and the adjacent neighboring rooms have. The room heating load corresponds to the sum of the heat losses / gains of all space-limiting surfaces. # Definition of task Required is the temperature that is applied to the outer surface of the room-limiting component (walls, floors, ceilings). This is determined by the adjacent space or environment. The following illustration shows four rooms separated by internal walls. Room one is separated by an inner wall of room two, room three and room four. Each adjacent room at room one has a different internal temperature, which has different effects on the heating load of room one. Three subsurfaces are required with the respective ambient temperatures (room temperatures), which are adjacent to the inner wall of room one. One of the three required surfaces is highlighted with red (thick) in the illustration. The adjacent temperature for this area corresponds to the room temperature of room three. Analogously, this applies to all space-limiting components (walls, floors, ceilings...). # Details We want to extract the following values from Revit models for every room: * Room ID * Room name * Room temperature * Room volume * Room area * Room height * Room perimeter (the length of the line delimiting a geometric figure or object) * Room is heated or unheated * Level of the room ** Hight of the level above the ground * Room belongs to which Housing Unit * adjacent element of the room (external air, ground (earth), heated, unheated) * heat transfer coefficient * dimensions of space-limiting components (Wall, door, window, ceiling, floor) ** height/depth ** length * component surface (Wall, door, window, ceiling, floor) * component ID * adjacent temperatures for space-bounding elements (temperature of either side of a wall) The value should be exported to an sqlite >= 3 database or to a mysql >= 5.7 database. The export plugin should be made for Revit >= 2017. All values (length, temperature etc.) must use the metric system!
