Multifunctional building component
A multifunctional building component is capable of serving as one or more of a window, a wall, a shading device, a roofing element, a color panel, a display, an energy harvesting device, an energy storage device, and an energy distribution device.
1. A multifunctional building component comprising
a structural element;
a color-changing element housed in the structural element that exhibits at least a reflective state in which incident light is reflected by the color-changing element;
an insulation element housed in the structural element to limit heat transfer; and
an energy-harvesting element housed in the structural element and arranged to receive an increased amount of light when the color-changing element is in the reflective state.
2. The multifunctional building component of claim 1 , further comprising an energy storage element housed in the structural element.
3. The multifunctional building component of claim 1 , further comprising an energy distribution element housed in the structural element.
4. The multifunctional building component of claim 1 , wherein the structural element is an insulating glass unit.
5. The multifunctional building component of claim 1 , wherein
the color-changing element is disposed within an interior space of the structural element adjacent to a surface defining the interior space;
the insulation element is disposed within the interior space of the structural element adjacent to the color-changing element; and
the energy-harvesting element is disposed within the interior space of the structural element proximate to a perimeter of the interior space.
6. The multifunctional building component of claim 1 , wherein the color-changing element is a reflective material and a color of the color-changing element results from reflection of incident light by the reflective material.
7. The multifunctional building component of claim 1 , wherein the color-changing element is a diffusive material and a color of the color-changing element results from diffusion of incident light by the diffusive material.
8. The multifunctional building component of claim 3 , wherein the color-changing element and the energy distribution element are combined into a single element of an energy radiating material and a color of the single element results from radiation of absorbed incident light by the energy radiating material.
9. The multifunctional building component of claim 2 , wherein the energy-harvesting and energy-storing elements harvest and store electrical energy.
10. The multifunctional building component of claim 2 , wherein the energy-harvesting and energy-storing elements harvest and store thermal energy.

12. The multifunctional building component of claim 3 , wherein
the energy-harvesting element includes one or more photovoltaic collectors; and
the energy distribution element distributes electrical energy.
13. The multifunctional building component of claim 3 , wherein the energy distribution element comprises an optical lighting system.
14. The multifunctional building component of claim 3 , wherein the energy distribution element comprises a thermal radiator.
15. A multifunctional building component comprising
a structural element;
an insulation element disposed within an interior space defined within the structural element adjacent to a surface defining the interior space and capable of serving as a bandblock filter;
a color-changing element disposed within the interior space of the structural element adjacent to the insulation element and capable of serving as one or more of an optical attenuator, an optical downconverter, or an energy harvesting element;
an energy storage element disposed within the interior space of the structural element adjacent to a perimeter of the interior space for storage of light, heat, electrical, or vibration energy; and
an energy distribution element disposed within the interior space of the structural element adjacent to the perimeter of the interior space for distribution of light, heat, electrical, or vibration energy from the energy storage element, wherein
a color state of the color-changing element, under control of an external control signal, is used to regulate a flow of energy into the energy storage element and to regulate a release of energy through the energy distribution element in the form of heat, light, electricity, or vibration.
16. The multifunctional building component of claim 14 , wherein the color-changing element is thermochromic.
17. The multifunctional building component of claim 14 , wherein the color-changing element is electrochromic.
