PMV-based comfort standards

These helpers describe static PMV-based comfort zones. They are distinct from adaptive comfort models such as comfort_model_adaptive(), which use running mean outdoor temperature and produce operative-temperature bands.

Usage

comfort_pmv_ashrae55(edition = "2017", range = c(-0.5, 0.5))

comfort_pmv_en15251(edition = "2007", breaks = c(-0.7, -0.2, 0.2, 0.7))

Arguments

edition

Standard edition. Currently "2017" for ASHRAE 55 and "2007" for EN 15251.

range

PMV comfort interval for ASHRAE 55.

breaks

PMV boundaries for EN 15251 comfort bands.

Value

A comfort standard object.
