A Net Zero Energy Building (NZEB) is a building with zero net energy consumption over a year. The total energy used annually is roughly equal to the renewable energy produced on site. NZEBs are highly energy efficient and meet demand through on-site renewables like solar or wind power, reducing greenhouse gas emissions compared to conventional buildings.

What makes a building net zero?
It uses as much energy annually as it produces from on-site renewable sources.

Efficiency measures plus on-site renewable generation.
New residential and commercial projects use high-efficiency envelopes, HVAC, and on-site solar to achieve net zero energy targets and lower operating costs.
Work with an energy consultant or HVAC professional to assess energy use and identify efficiency and renewable upgrades.

NZEBs can remain grid-connected, sending excess power to the grid and drawing power when renewables are low.
Is net zero the same as off-grid?
No. Net zero buildings can stay connected to the grid while balancing annual energy use.
Do net zero buildings cost more to build?
They can, but energy savings and incentives often offset upfront costs over time.
What systems matter most for net zero?
Envelope insulation, efficient HVAC, lighting, and on-site renewables are key.
