Package of different window ventilation models

## Information

#### Overview

This package contains models of window ventilation with various types of sash openings from literature.

Currently, the models are only applicable for single-sided ventilation.

#### Window opening types

This package considers the following types of window openings:

- Simple opening, without window sash
- Side-hung opening, in- or outward, for casement window
- Top-hung opening, outward, for awning window
- Bottom-hung opening, inward, for hopper window, tilt window
- Pivot opening, vertical or horizontal, for center hinge window
- Sliding opening, vertical, for single-hung or double-hung window
- Sliding opening, horizontal, for slider window

These opening types are included in WindowOpeningTypes.

#### Opening area types

For hinged and pivot openings, there are five different types to define the opening area:

- Clear opening area, as shown in the figure on the left
- Geometric opening area, as shown in the figure in the middle, see function geometricOpeningArea
- Projective opening area, as shown in the figure on the right, see function projectiveOpeningArea
- Equivalent opening area, derived from clear opening area and geometric opening area, see function equivalentOpeningArea
- Effective opening area, derived from clear opening area and equivalent opening area, see function effectiveOpeningArea
