Ultra-low energy consumption building energy storage equipment

What are ultra-low energy consumption buildings?

Among them, ultra-low energy consumption buildings (ULEBs) have become representative of efforts to balance the service demand and the need for energy self-sufficiency (Ohene et al., 2022). In 1976, the concept of zero-energy consumption buildings (ZEBs) was first proposed by Esbensen (Danish Technical University) (Wilberforce et al., 2021).

Can ultra-low energy consumption be implemented at different energy consumption levels?

To date, studies on the implementation of ultra-low energy consumption have been based mainly on the analysis of the effects of certain technologies, and few studies have examined the regional implementation paths at different energy consumption levels.

Why is the operational state of energy-efficient ultra-low energy consumption buildings important?

The operational state of energy-efficient ultra-low energy consumption buildings is very important to achieve energy savings and emission reductions, which are currently necessary considerations for the development of the building industry.

Can ulebs be realized only by the application of existing energy-saving technologies?

The comprehensive application of existing energy-saving technologies indicates that the minimum EUI of conventional buildings in HSCW areas is 38.43 kWh/ (m 2.a), while the energy consumption target value in these areas is 29.04 kWh/ (m 2.a). This shows that ULEBs cannot be realized only by the application of existing active technologies.
