摘要
Disclosed are various structure surface configurations and related methods. An exemplary structure includes a facade that has grooved cavities that are configured in a manner that reflects summer (cooling season) insolation and absorbs winter (heating season) insolation. The effective absorptivities of the exemplary structure for various cavity reflectance characteristics, i.e., a wide range of diffuse and specular reflectance characteristics, are evaluated using a Monte Carlo model. The calculations in an illustrated embodiment are performed for the latitude of 41° N where both heating and cooling loads are significant. Embodiments of various structures are similarly within the scope of the disclosure for locations of different latitudes and longitudes.
