Teach Green Building Technology in Your Lessons with the LJ ECO House

Escalating energy and material costs, coupled with the targets for reducing CO2 emissions, make understanding the efficient use of energy in the home an increasingly important topic. This field is fast emerging as an industry that requires a great deal of research and development as well as a new set of technical skills. This learning resource is focused on our innovative ECO Building, a classroom resource that allows practical investigation of energy in the home. It has been specifically designed to allow tutors and students to practically explore green energy technology on a micro-generation scale. The building has a 6 panel solar PV array and a solar water heating panel mounted on the roof. A pump and water tank with temperature sensor complete the solar hot water system. A powerful infrared lamp allows us to simulate sunlight in a classroom situation. A separate wind turbine is also provided and this is typically powered by a simple desk fan. A battery storage system collects any energy generated that is not instantly used and allows it to be used latter. An intelligent building control system is used to select between energy provided by the grid or from the renewable sources. A range of sensors provide measurement of room temperatures, light levels and power and energy consumption. A heater is provided in one room and a heatpump is provided in another. When used, these show students how heating a room and more significantly, cooling a room using electricity from the
