A zero net energy building (ZNEB) uses clean, renewable resources to produce energy on-site in an amount that is equal to or greater than the total amount of energy used on-site over the course of a year.
A zero net energy building (ZNEB) is one that uses clean, renewable resources to produce energy on-site in an amount that is equal to or greater than the total amount of energy used on-site over the course of a year.
Designers and builders use integrated design and building strategies to produce ultra-efficient residential and commercial structures. They also decide what types of renewable on-site generating and energy efficiency tactics and technology will help the buildings achieve improved energy performance. The combination of these factors will result in a cozy, healthier home or workplace, lower energy expenses, and a reduction in greenhouse gas emissions, all of which make ZNEB buildings appealing and worthwhile.
These case studies, which highlight zero and nearly zero net energy buildings that have been either constructed or modified, are intended to educate and motivate you to think about what is possible. Indeed, creative architects, contractors, and homeowners are revolutionizing the way we construct buildings in Massachusetts and providing desperately needed solutions to cut down on energy waste.
What is the Difference Between Zero and Net Zero?
Although the terms “Net Zero” and “Zero Energy” are used in industry, they are not interchangeable because the two methodologies differ.
This entails finding other ways to offset the energy utilized on-site. In order to attain net zero, a project, for instance, would need to create 500,000 kBTU of on-site renewable energy if it uses 250,000 kBTU of electricity and 250,000 kBTU of natural gas.
The Department of Energy, on the other hand, defines zero energy as the requirement to produce on-site as much renewable energy as it consumes in source energy. This includes both the energy used to produce the electricity or natural gas as well as the energy used to consume it. This analyses each energy source separately and takes into account elements like transmission loss and energy generation efficiency. In this case, since their sources differ, one unit of electricity does not equal one unit of natural gas.
Since net zero does not take into consideration the variations in fossil fuels or the energy used in sourcing and transportation, it is less complicated and easier to attain than zero energy. Additionally, it permits some industries to run at greater fuel costs.
