My house has slate shingles and cooks in the summer like you wouldn't believe. Sun Lizard Solar Climate Control Solutions uses zero emission technology to regulate these dynamics of temperature in your home using natural sources. Using special roof surfaces and solar heat bank cells to collect the sun's energy during daylight hours the Sun Lizard system is able to heat your home when weather is chilly by up to 50 degrees Celsius and cool your home using air from below your home.
During time of high heat natural air currents are maximized to remove the hot air from the home with stored electrical energy to run a circulation fan system. Cold air in lower parts of your home are tapped into for circulation to the living area. Air in basements, around underground piping, and other low sources is filtered through vents and put to use.
In addition, heat can stay trapped under the roof and in the eaves of homes, making your house act as a thermos, keeping you sweaty all night long. A key feature of the Sun Lizard system used to regulate house and building temperature is Ceiling Diffusers which allow hot air to escape upward, using the natural flow of air to your advantage. I know when I open my closet door in the summer over the eaves of the house a blast of hot air rushes into the room, I can feel the warmth in the walls in my third floor bedroom. To remove this energy when it is unnecessary and utilize it when warm air is needed saves the need to burn gas/oil/electric systems for comfort.
Sun Lizard technology puts practical solutions to efficient use (in conjunction with proper insulation) to minimize the need to run energy intensive AC and heating units. Sun Lizards is based in Australia, but their technology can be called upon by anyone around the globe with a little elbow grease and initiative.
