What Is A Zero-Energy Building, And Why It Is Essential These Days?

We can say that a building with zero energy balance is a Building Energy Modeling with a high level of energy efficiency, where the little amount of energy required must come from renewable energy sources. These Zero Energy Building Singapore are designed to contribute to the general objective of reducing energy consumption and CO2 emissions with the least economic and environmental cost.

The condition that a zero energy building must satisfy is that the weighted renewable generation of energy exceeds the weighted demand in a specified period, usually one year. The energy balance can be determined either by balancing between supplied and exported power or by balancing energy demand and generation. 

The idea of zero energy buildings was born from facing the search for possible solutions to the severe problems of pollution and climate change on the planet. This concept refers to the construction of buildings that can cover all their energy needs by themselves. That is, buildings designed and built with ecological materials, renewable sources, and a series of technologies that allow them to have a high level of energy efficiency.

To be considered within this group, a building must have a net consumption of energy and zero carbon emissions per year. For this, it uses systems that generate electricity through renewable sources. It means that the power provided for the building itself must be equal to the energy demanded by it. The zero-energy buildings are also known as ultra-low energy buildings. The ZERO Building Energy Modeling has become the ideal design for buildings with low environmental impact.

Some of the techniques used within a zero energy building are based on heat, the installation of solar cells or fuel cells to generate electricity. The construction of these works requires a multidisciplinary team made up of environmental engineers, physicists, and industrial designers, who must evaluate various variables before starting. Among these aspects to consider are the orientations of the building concerning the sun, thermal insulation, and the location of the windows, the depth of glass and walls.

The goal of making the construction of zero energy buildings much more massive seeks to generate solutions to the serious environmental problems that our planet faces.
