A thermally switched optical downconverting (TSOD) filter is a self-regulating device including a downconverter that converts incoming light at a variety of wavelengths into longer-wavelength radiation and then directs it using one or more bandblock filters in either the inward or outward direction, depending on the temperature of the device. This control over the flow of radiant energy occurs independently of the thermal conductivity or insulating properties of the device and may or may not preserve the image and color properties of incoming visible light. The TSOD filter has energy-efficiency implications, as it can be used to regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The TSOD filter also has aesthetic implications, since the device has unique optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls. The TSOD filter has particular, but not exclusive, application as a building material.

A flat or curved photochromic laminate structure and a plastic photochromic lens blank can be produced in a simple and efficient manner from relatively low-cost polymeric sheet materials. These laminates can be used to provide goggles, face shields, windows, window coverings, skylights, and optical lenses having efficient, uniform and high quality photochromic properties. The use of a polyesterurethane as the binder for the photochromic material has been found to improve the performance of the photochromic material. There may be a desire to have a protective exterior layer (e.g., an abrasion resistant layer) in combination with the lens system, but that may be provided in various methods. In the case of using the laminate in a goggle application, the laminate may be hard coated on one or both outer surfaces with an abrasion resistant coating, antireflective coating, and/or an anti-fog hard coating.

A constructed enclosure, adjacent to an interior habitable space, uses a microprocessor-based control unit to operate enclosure openings to provide a multi-layer insulation barrier containing or creating heat, or providing a radiant barrier, isolating by open air, a thermal insulating layer from warm exterior surfaces, maximizing insulation values. The enclosed space, through the use of openings, which in one embodiment are windows, skylights and dampers connected to louvers, is heated by radiant exposure or cooled by natural air flow or exhaust fan. Return air is heated upstream from a forced air heating unit by traversing ductwork heated by the enclosure and by direct solar exposure from enclosure windows. Enclosure openings to the habitable interior spaces create air displacement drawing warm air out of the interior and fresh air in through exterior windows. The energy efficient system is tailored for immediate climate specific conditions.
