Customer ServiceIn the PVT scenario, the solar collectors generate both heat and electricity that are consumed differently in buildings. The thermal output of the PVT collectors is stored in a properly-sized storage tank (62 liters/m 2 of panel area ) and then is used to directly meet any thermal load (not energy demand) in the building.
In this numerical study, the potential application of a centralized solar water-heating system in high-rise residence was evaluated. Arrays of solar thermal collectors, that occupied the top two-third of the south and west façades of a hypothetical high-rise residence, were proposed for supporting the domestic hot-water system.

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.
Conclusion In Hong Kong, there is a good application potential for the centralized solar water-heating systems in new multi-storey residential developments. With a high density of tall buildings, it is more viable to take advantage of the vertical surfaces of these buildings, instead of the limited roof spaces.
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.
