Net Zero Energy Buildings (NZEB) – What does it mean?

A net zero energy building produces as much energy as it uses over the course of a year.

NZEBs are very energy-efficient buildings, with low energy needs typically met through the use of onsite renewable energy. NZEB advantages include reduced total cost of ownership due to improved energy efficiency, isolation from future energy price increases and safeguards from future legislative restrictions including carbon emission tax that is being seriously considered by several nations.

Onsite solar PV systems are probably the most commonly used technology to generate energy. There are several buildings world-wide including healthcare facilities that already utilize solar PV panels to generate onsite energy. Other energy sources such as micro wind turbines are also being explored in a big way world-wide, while biogas and biomass systems are still developing.
