New Hoop for Builders to Jump Through – Zero Energy Buildings

Zero Energy Building

This pre-fabricated house in Germany is a near-zero energy building

ZEB is one of the latest acronyms to hit the fields of Air Conditioning and Heating and of Building Sciences. It stands for Zero Energy Building. In theory a Zero-Energy Building eliminates the use of non-renewable energy sources in favor of on-site and locally available renewable sources such as wind, solar power, and hydro-energy. An energy efficient design and educating the building’s occupants in managing their energy usage are also critical to achieving a zero-energy or near zero-energy goal. The obvious benefits of this goal are increased energy efficiency and improved energy sustainability. These buildings may be more secure in the event of a terrorist attack on traditional utility infrastructure.

The National Institute of Building Sciences (NIBS) and the U.S. Department of Energy (DOE) are currently working together to develop a common definition for zero-energy buildings. The European Union (EU) has actually been pursing this goal for years. A 2010 Directive requires EU member states to ensure that, after December 31, 2018, all “new buildings occupied and owned by public authorities” be near zero-energy buildings.

Pictured above is pre-fabricated near-zero-energy home in Germany. Not bad! However the real testing ground for zero energy buildings would be the successful design and implementation of such structures here in southeast Texas where the greatest battle would be keeping the interior cool and comfortable.
