A net-zero energy building (NZEB) is a building that generates as much energy as it consumes on an annual basis. NZEBs use a combination of energy efficiency measures and renewable energy sources to achieve net-zero energy.
Some of the features of NZEBs include:
- Energy-efficient design: NZEBs are designed to use less energy than conventional buildings. This includes features such as high-performance insulation, efficient windows, and energy-efficient mechanical appliances.
- On-site renewable energy: NZEBs generate their own energy from renewable sources such as solar panels, wind or water turbines.
- Energy storage: NZEBs may use energy storage systems (batteries) to store excess energy generated during times of low demand. This energy can then be used to meet demand during times of high demand.
The aim of NZEBs is to reduce or neutralize the environmental impact of buildings. By generating their own energy from renewable sources, NZEBs can help to reduce reliance on fossil fuels and mitigate climate change.
Here are some of the benefits of NZEBs:
- NZEBs can save building owners money on their energy bills.
- NZEBs can provide a more comfortable living or working environment by reducing drafts and improving indoor air quality.
- NZEBs can increase the value of a property.
- NZEBs can help to reduce greenhouse gas emissions, reduce impacts to climate change and improve air quality.
- NZEB can be more resilient during power outages and natural disasters by creating and storing their own power and creating safer living spaces with a better building envelope that protects occupants from extreme weather conditions.
