The idea that a hot bath can offer benefits similar to those of exercise sounds counterintuitive, but the results of a couple of other studies suggest that passive heating
is an important new area of research.
These reported the core temperature response of 347 pregnant women to heat stress, either through exercise or through passive heating
, such as using a sauna or sitting in a hot bath.
This system has the following four independent functions: passive heating
, heat preservation, heat insulation, and passive cooling.
Al Maadeed explains the focus of the project: "The project is focused on the development of plastic heat absorbers called 'Phase Change Materials' (PCM) based on recycled polyethylene and paraffin wax which can be used as components that improve the passive heating
or cooling of buildings to save electrical energy and reduce carbon dioxide emissions."
Other recently neglected uses of the sun are passive heating
and drying clothes on clotheslines.
(The old terminal is used now as a workforce and charter terminal.) Super-insulated walls, in-floor heating, passive heating
and lighting via extensive use of windows, heat recovery and displacement ventilation figure large in reducing the cost of heating and cooling the terminal.
The windows to the southern aspect are larger to enhance the views and also to provide passive heating
. Storm water is stored in large tanks beneath the south facing patio which, in combination with the lakes, provide the water for the grounds.
The use of thermal insulation, renewable energy, reflective surfaces and colors for shading are just some of the passive heating
, cooling and lighting techniques applied in bioclimatic architecture.

and ventilation are assisted by roof monitors that also contribute to daylighting, while mechanical heating and cooling are provided as needed by four variable refrigerant flow units.
Passivhaus buildings are constructed to be virtually air tight and they generally require no conventional heating or cooling systems, instead relying, as the name suggests, on passive heating
and ventilating solutions.
