ASHRAE 160/ DA07 Moisture

ASHRAE 160/ DA07 Moisture Modelling on Speckel
Our moisture modelling approach is unique, where the modelling requirements of ASHRAE 160/ DA07 are set, and reporting is automated.  A typical wall is modelled in less than 10 minutes, including simulations and results.

Moisture modelling, or hygrothermal modelling, is an advanced simulation method called Heat and Moisture Transfer (HAMT). 
The HAMT model takes into account various influential factors such as temperature gradients, humidity differentials, material properties, airflow patterns, and vapour pressure differentials. By incorporating these variables, the model accurately predicts the behaviour of heat and moisture transfer across different layers of a building assembly, including walls, roofs, floors, and insulation materials.
Below is a step-by-step overview of the inputs required for our moisture simulations. All inputs are based on ASHRAE 160/ DA07, in line with National Construction Code 2022 requirements.
➡️ Study
Set the run period and focus of your study.
​
🏢 Model
Set orientation, cavity ventilation and buildng volume.
​
💧 Internal Conditions
Set a moisture loading scenario, based on temperature, relative humidity and services.

Run a Simulation
To start simulating ASHRAE 160/ DA07 moisture assessment, the first step is the same as Thermal, select 'Moisture' in the simulation panel, and a pop-up will appear with the following inputs. Here is a video to get you going.
