Environmental characteristics of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences) are controlled to eliminate, reduce or ameliorate adverse or harmful aspects and introduce, increase or enhance beneficial aspects in order to improve a “wellness” or sense of “wellbeing” provided via the environments. Control of intensity and wavelength distribution of passive and active Illumination addresses various issues, symptoms or syndromes, for instance to maintain a circadian rhythm or cycle, adjust for “jet lag” or season affective disorder, etc. Air quality and attributes are controlled. Scent(s) may be dispersed. Hypoallergenic items (e.g., bedding, linens) may be used. Water quality is controlled. Noise is reduced and sounds (e.g., masking, music, natural) may be provided. Passive and active pathogen controls are employed. Controls are provided for the occupant and/or facility personnel, as is instruction, and surveys, including assessing wellness.

A dry space creation apparatus includes a processing tank, expansion members, an ejection unit, a dry gas supplier, and a controller. The processing tank has an internal space. The expansion members are provided in the processing tank and expand while leaving part of the internal space. The ejection unit ejects gas in the internal space out of the processing tank. The dry gas supplier supplies dry gas to the internal space. The controller performs first control to allow the ejection unit to eject the gas in the internal space out of the processing tank with the expansion members expanding, and then performs second control to allow the dry gas supplier to supply the dry gas to the internal space with the expansion members contracting.

Environmental characteristics or scenes of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences, or other spaces or sub-spaces) are controlled to facilitate certain activities of a user in the environment by increasing focus, preparing for sleep, directing movement, masking ambient noise, and improving air quality, among others. Controllable characteristics include, for example, lighting, CO.sub.2/O.sub.2 levels, humidity levels, sound, aroma, and air temperature. Controls are provided for the occupant and/or facility personnel to select activities or scenes, or sensors detect the activity and implement an appropriate scene.

A dehumidifier/cooling apparatus for use in a room having an elevated temperature and/or humidity is provided which utilizes the natural coolness of tap water to condense water vapor from the air or merely cool the air. The tap water line is diverted into a heat exchanger upstream of a hot water heater to dehumidify and/or cool the air in the room the air and remove the latent heat given off during condensation to cool and/or dehumidify the room air and to pre-heat the water entering the hot water heater. An air moving device powered solely by water moving through the tap water line directs a flow of air through the heat exchanger.
