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.
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.
Conversely, the best-performing residential and commercial buildings have EUIs of 50–75 kWh/m 2 a. Only if building heights are limited to 5–10 floors does the available solar energy, and thus the permitted EUI, reach 50–75 kWh/m 2 a.
Only if building heights are limited to 5–10 floors does the available solar energy, and thus the permitted EUI, reach 50–75 kWh/m 2 a. Therefore, we recommend that policymakers not require high-rise buildings to be net-zero energy, unless they are prepared to limit building heights to 5–10 floors. 1. Introduction
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.
Therefore, by considering the use of solar passive strategies and active technologies as an alternative in high-rise buildings, this study tries to fill some of the current gaps as much as possible and its proposed fundamental message is changing architects’ and construction builders’ view in dealing with the subject. 1.1. Research methodology
Solar considerations in high-rise buildings
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. These strategies can be applied and adapted to high-rise buildings by using direct solar gain, indirect solar gain, isolated solar gain, thermal storage mass and ...
