Introduction. The building sector is expected to play a critical role in the energy transition, mitigate global climate change, and achieve sustainable development goals (IPCC, 2014; Wang et al., 2018; Zhou et al., 2018).Accurate estimation of building energy consumption (indicating the delivered energy to the buildings in this study) is the
Shaun Brodie • 11/04/2024. A Battery Energy Storage System (BESS) secures electrical energy from renewable and non-renewable sources and collects and saves it in rechargeable batteries for use at a later date. When energy is needed, it is released from the BESS to power demand to lessen any disparity between energy demand and energy
"China Tianying''s ''100MWh complete set of gravity energy storage equipment'' is currently the world''s largest complete set of gravity energy storage equipment. Its basic technical route is to use new energy such as wind and solar power or grid valley and flat power to raise the gravity block to a certain height, so as to convert the
EnergyPlus™ is DOE''s open-source whole-building energy modeling (BEM) engine, the successor to DOE-2.1E. Under development since 1997, EnergyPlus embodies the state-of-the-art in BEM knowledge in a comprehensive and robust engine that is continuously maintained, thoroughly documented and fully supported. BTO releases two annual
Improving the energy performance of buildings is the key to achieve these goals, as buildings are responsible for 40% of energy use and 36% of CO 2 emissions in the EU [1], [2]. The easiest and also the most promising measure is to increase the utilization of solar energy.

An increase in PCM as an energy-storage aggregate in energy-storage concrete also decreases the 28-d compressive strength of the energy-storage concrete by approximately 40 − 70%, thus greatly reducing its service life [17 − 20].
Buildings. Thermal Energy Storage Systems for Buildings Workshop. The Building Technologies Office (BTO) hosted a workshop, Priorities and Pathways to Widespread Deployment of Thermal Energy Storage in Buildings on May 11–12, 2021. It was focused on the goal of advancing thermal energy storage (TES) solutions for
The energy consumption of office buildings is an important part, accounting for 30% of the sub-sector [52]. However, for zero-energy office buildings, there is still a lack of investigation on the short-term energy flexibility in responding to the requirements of the energy supply side, especially for buildings in China.
Adapting to the local climate is the key to developing nearly-zero energy buildings (NZEBs). During cooling season in Western China, the climate conditions are characterized by a large daily temperature range and high solar radiation, and improving the thermal storage performance of buildings is an effective passive cooling design strategy
Furthermore, a computational simulation for an office building proves that 2.6–10.2% energy could be saved by thermochromic transparent hydrogel wood in four different climate-zone cities.
