A recent KXAN news report featured the story of a Round Rock couple who built their home specifically for energy efficiency. Beginning with a strong metal roof designed to support the weight of solar panels, they installed 24 panels which generate ample amounts of electric current.
In winter months, their electric bills are very low. However, as spring and summer months bring greater levels of heat and sunlight, their electricity bills fall into a negative zone. That’s because their photovoltaic panels are producing more electricity than their home consumes. To further reduce electrical consumption, the couple has replaced many incandescent lights with solid state lighting. Special skylights called “solar tubes” provide bright interior lighting during daylight hours, making their home even more efficient. Efficient foam insulation and a roof design which provides longer overhangs shades the walls and further reduces the electricity needed for cooling the home. In addition to this, their home’s heating and cooling unit uses a geothermal well. For more information, click on this web link: News Link
