1/ There must be something more hi-tech than white masonry paint to repaint the render. I'm thinking of the reflective glass beads on road signs and number plates, but optimised for peak infra-red wavelength of sun's radiant heat.2/ Chain drilling out a brick in the loft section of a redundent chimney to fit a small fan to extract loft heat into the stack and chimney pot, any cautions relating to breaking through pargetting or whatever?Have already adopted external to windows African sail shades version of brieze solar and expanded metal loft access panel for summer. And all windows closed all day unless at night is cooler oudside than core of building, again with expanded metal mest, as anti fly, mice,rats, burglars.
