There is a lot of pressure from both real estate investors and the government to make new buildings more energy efficient. As a result, making a building energy efficient is often a necessity to make sure a construction project complies with local laws, as this SBEM calculations page shows: https://focus360energy.co.uk/sbem-ca....

As to how that efficiency is achieved, there are a lot of options available. It usually involves designing the building’s heating, cooling, water, and lighting systems using efficient solutions and following certain standards.

Efficiency can also be achieved by making use of features of the environment to help reduce energy needs in the building. This includes the use of passive heating and cooling systems that rely on local wind currents and sunlight to help manage the building’s temperature. Geothermal heating and cooling systems can also be useful in this department.

There is a lot of complexity involved in managing a building’s energy consumption and carbon footprint. This is why running tests and getting expert assessments is so important.
