Thereby, as few studies have been done by architects such as Ken Yeang on the amount of energy consumed in high-rise buildings, the author attempts to make viewpoints of some architects, construction builders and also users more clear about the influences of using passive solar strategies and active solar technologies on tall buildings.
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.
If we go with a traditional solar installation, it takes up the entire rooftop space and only gives us a height of 500mm above the ground (it is for cleaning purposes to remove dust and debris). If we choose an elevated design, we will have a clearing distance of 2000 mm (depending on the consumer’s needs) from the ground level.
For instance, to meet the building heating demand, three paths are available: 1. direct use of solar heat generated through a thermal collector, 2. conversion of solar electricity to heat in an electric-resistance heater, and 3. running a heat pump using the solar electricity. The same three paths are available for Domestic Hot Water (DHW). Fig. 2.
In design, the most occupied living spaces should be considered on the solar side. In order to absorb the heat and set thermal inertia that decrease the temperature fluctuations inside the building, the floor should be constructed from high thermal masses.
Feasibility of achieving net-zero energy performance in high-rise ...
A limited area for harvesting solar energy, low efficiency of technologies available, and finally low density of solar energy are the key hindrances that make achieving net-zero energy performance using solar energy difficult. For high-rise buildings, reaching the net-zero energy goal is even more difficult, mainly because of their large floor ...

Solar energy | Definition, Uses, Advantages, & Facts | Britannica
The potential for solar energy to be harnessed as solar power is enormous, since about 200,000 times the world''s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its exploitation in many places.
