• Highrise living for the win, I think being off the ground helps a lot summer or winter.

  • Sort of similar. Edwardian detached house converted into flats, so we have a flat below us and a flat above. Having 4 external walls isn't great but only 2 have windows in them, all but 3 of the 9 windows in the flat are double glazed. We get the benefit from the heating being on below and above us most of the time, and it's rare that all 3 of the flats are away at the same time.

    Still need to add in a sensor to collect how often my heating is on (will be attaching a Dallas 1-wire temp sensor to the hot water and central heating pipes from boiler), and also adding sensors to see much gas/elec is being used*.

    * There's an LED on the electricity meter that flashes every 1/1000th of a kWh of use. Think there's something similar on the modern gas meters too. http://www.reuk.co.uk/wordpress/solar/flashing-led-on-electricity-meter/
