Abstract: A method of controlling building service systems includes predicting, based on a shading and lighting prediction model, a visual comfort condition and a lighting condition with respect to a region of a building; optimizing, based on a first multi-component cost function including a plurality of components relating to a plurality of lighting or thermal performance parameters, one or more first control parameters for controlling the lighting system and the shading system based on the predicted visual comfort condition and the predicted lighting condition; predicting, based on a building dynamics model, a plurality of building response parameters based on the predicted visual comfort condition and the predicted lighting condition; and optimizing, based on a second multi-component cost function including a plurality of components relating to the plurality of building performance parameters, one or more second control parameters for controlling an air-conditioning/heating system based on the predicted plurality of

Abstract: A method of controlling building service systems associated with a building for optimizing a plurality of building performance parameters with respect to a region of the building, the building service systems including an air-conditioning and/or heating system, a lighting system and a shading system, is provided.

Abstract: The present invention generally relates to a dispersion comprising a plurality of core-shell particles, wherein the core comprising non-fluorinated polymer and the shell comprises fluorinated polymer. It also relates to the use of the said dispersion as an additive in a coating formulation in at least 10 wt %, wherein substrates coated with said coating formulation exhibit improved solar-reflective and anti-dirt properties. In preferred embodiments, the said core comprises methyl methacrylate monomer and the said shell comprises hexafluorobutyl acrylate, hexafluorobutyl methacrylate, tridecafluorooctyl arylate or perfluorooctyl acrylate.
