01. Wind Flow Analysis

Andreeq Bunica 9.2. GH Wind, Energy & Building Simulation

9.2.01. wind flow analysis

Date published: August 23, 2022

DESCRIPTION

GHWind is a Fast Fluid Dynamics (FFD) Wind Simulation plugin.

PROCEDURE

1. Define a 3D domain area to carry out the analysis
2. Define the resolution of the analysis with a cell size input
3. Input the mesh for analysis
4. Define the discrete mesh for the solver
5. Define the wind properties including wind speed and terrain conditions
6. Run the solver using a Boolean toggle
7. Display the wind field: you can adjust the xyz toggle and section slider to preview a specific section plane on specific axis
8. Display the wind pressure on the input mesh surface

This exercise is using Grasshopper version 1.0.0007

9.1.03. psychrometric chart

Date published: August 23, 2022

DESCRIPTION

This example generates a specific location’s phychrometric chart using moisture measurement processes including physical and thermodynamic properties like dry bulb temperature, wet bulb temperature, humidity, enthalpy and air density.

PROCEDURE

1. Import the .epw file.
2. Generate the psychrometric chart and evaluate a set of temperatures and humidity ratios in terms of indoor comfort.

01. Sunpath and sunlight hour analysis

Andreeq Bunica 9.1. Ladybug, Energy & Building Simulation

9.1.01. sunpath and sunlight hour analysis

Date published: August 23, 2022

DESCRIPTION

Ladybug allows users to import and analyse standard weather data in Grasshopper; draw diagrams like Sun-path, wind-rose, radiation-rose, etc; customise the diagrams in several ways; run radiation analysis, shadow studies, and view analysis. This exercise uses a time- and location-specific sun trajectory to count the number of hours building surfaces are exposed to direct sunlight.

PROCEDURE

1. Import the .epw weather file.
2. Adjust analysis period
3. Ladybug sun path diagram
4. Ladybug sunlight hour analysis
5. Mesh selector
