6 Frequently Asked Questions about “High-rise residential external solar energy displacement”
Can solar energy be used in high-rise buildings?
As urban areas become more populated and densified, it becomes more important to have low-energy high-rise buildings with minimal GHG emissions. On this account, this study evaluates the feasibility of achieving net-zero energy performance by employing solar energy in high-rise buildings in North America.
Can high-rise buildings gain solar radiation?
Finally, high-rise buildings have great potential to gain solar radiations because of their vast facades. Analyzing case studies illustrate that applying solar passive strategies in high-rise buildings have a meaningful effect on reducing the total annual cooling and heating energy demand.
Does energy demand affect solar gain in a residential building?
The results show that there was a high correlation between energy demand and solar gain for any flats of this residential building. In this research, BES was used to analyse the performance of the 12-storey residential building under different surrounding conditions.
Can solar-powered high-rise buildings achieve net-zero energy status?
Examined feasibility of solar-powered net-zero energy high-rise buildings. The maximum permitted EUI by net-zero energy status is 17–28 kWh/m 2. Meeting this EUI is harder than most stringent building codes. Taller the building, harder it becomes to achieve net-zero energy status. Building orientation impacts maximum permitted EUI.
Do neighbouring buildings affect energy performance of a high rise building?
Influence of neighbouring buildings on the energy performance of a high rise building. Energy demands and thermal comfort performance of the building in Copenhagen, Beijing and Singapore were compared. The impact of surrounding building number, height and position on the target building's energy performance were evaluated.
How does solar radiation affect building solar gain?
The amount of solar radiation is related to building solar gain directly. Previous sections show that the residential building's cooling demand was low during summer, and the solar radiation mainly affected the heating energy demand.
