Light and/or heat management system for a building, a building, and a method for light and/or heat management in a building

A method for light and/or heat management in a building, the method comprising:

• supplying, by a water supply system, water into a gap of a panel formed by at least two transparent sheet layers disposed in a frame;
• evaporating said water in a humidification unit disposed in said gap by exposing said humidification unit to heat, thereby producing humid air in said gap;
• and
• adjusting a heat transmissivity and/or transparency of said panel by controlling the humidity in said gap,
• wherein adjusting a heat transmissivity and/or transparency of said panel comprises using a blower to controllably remove humid air from said gap and thereby control the humidity in said gap.

A method for light and/or heat management in a building, the method comprising:

• supplying, by a water supply system, water into a gap of a panel formed by at least two transparent sheet layers disposed in a frame, wherein supplying, by the water supply system, water into the gap comprises supplying saltwater into said gap;
• evaporating said water in a humidification unit disposed in said gap by exposing said humidification unit to heat, thereby producing humid air in said gap;
• adjusting a heat transmissivity and/or transparency of said panel by controlling the humidity in said gap,
• leading humid air from said gap to a dehumidification unit;
• and
• extracting freshwater from said humid air in said dehumidification unit.

A method for light and/or heat management in a building, the method comprising:

• supplying, by a water supply system, water into a gap of a panel formed by at least two transparent sheet layers disposed in a frame;
• evaporating said water in a humidification unit disposed in said gap by exposing said humidification unit to heat, thereby producing humid air in said gap;
• obtaining information indicative of an amount and/or a direction of incident solar radiation and/or a current indoor climate;
• and
• adjusting a heat transmissivity and/or transparency of said panel by controlling the humidity in said gap, wherein adjusting the heat transmissivity and/or transparency of said panel comprises adjusting the heat transmissivity and/or transparency of said panel based on said information.
