Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Photovoltaic (PV) heating is a promising technology for achieving fossil fuel–free heating and carbon neutrality in the building sector. Cost-effective energy storage plays a critical role in PV heating to solve the temporal mismatch between supply and demand. Herein, we propose the concept of using a building envelope as an active energy-storage device for a PV heating system, thus transforming the building envelope into a thermal battery. Experimental results show that the energy storage capacity of 142 kW h/m 2, which is higher than that of conventional thermal storage systems. We developed a top-down macro performance assessment model to quantify the contribution of a PV heating system using a building envelope as energy storage. By our estimation, the envelope-embedded system can reduce heating-related CO 2 emissions by 7435.7 tons annually in northern China. Our study provides insights into innovative energy-saving building energy storage systems that can help achieve global carbon neutrality and sustainability.
