Indoor model parameters

Overview

Since r31xx an indoor climate and energy demand model is available in PALM.
The indoor climate and energy demand model based on the DIN EN ISO 13790:2008 with simplfified dynamic hour-based procedure.
This model is a equivalent circuit diagram of a three-point RC-model (5R1C). It take account to following parts:

• different zoned building physical properties (material, building year...)
• transmission and solar heat gains (with reduction by sunprotection)
• different ventilating properties (for scheduled empty and occupancies rooms)
• different internal heat gains (for scheduled empty and occupancies rooms)
• thermal comfort requirements (air change, target temperature)
• heat recovery factors (effiency of heat recovery)
• plant irreversibilities

This module differ between indoor-air temperature an average temperature of indoor surfaces which make it possible to determine thermal comfort.

Working in progress:

• output of heatfluxes and indoor temperature in netcdf data
• reduce the building volume to netto ground surface to take respect costruction areas like walls and ceilings.
• emmisivity change through window blinds because of sunprotection
• make spinup and restart runs possible
