Near Zero Energy Building Consulting

█ Near Zero Energy Building Consulting

Nearly zero-energy buildings refer to adapting to climate characteristics and site conditions, minimizing building heating, air-conditioning, and lighting requirements through passive building designs, maximizing energy equipment and system efficiency through active technical measures, and making full use of renewable energy. The energy consumption provides a comfortable indoor environment, and its indoor environmental parameters and energy efficiency indicators meet the requirements of the "Nearly Zero Energy Building Technical Standard" GB/T51350-2019.

◆ The level that can be achieved without the help of renewable energy and active and passive technologies (reduced by more than 50%)

Through passive technical means, the heating and cooling demand of buildings is greatly reduced, and the efficiency of energy equipment and systems is improved. It is the primary manifestation of near-zero-energy buildings. Its indoor environment parameters are the same as those of near-zero-energy buildings, and its energy efficiency index is slightly lower than that of near-zero-energy buildings.

◆ Utilize renewable energy (60%~75% reduction) + active and passive technology

The term "Nearly Zero Energy Building" originated from the European Union. Taken from the "Building Energy Efficiency Directive" issued by the European Union on July 9, 2010, all member states are required to ensure that all new buildings owned or used by the government meet the requirements of "nearly zero-energy buildings" from December 31, 2018 ; From December 31, 2020, all new buildings will meet the requirements of "nearly zero energy buildings".

◆ Renewable energy is greater than or equal to the building's own energy consumption + active and passive technologies

The term "zero-energy building" originated from the United States. It was taken from the "Building Technology Project 2008-2012 Plan" of the U.S. Department of Energy. In September 2015, the U.S. Department of Energy released the official definition of zero-energy An energy-efficient building whose annual energy consumption is less than or equal to the energy generated by the building itself and nearby renewable energy sources.
