Abstract
The paper aims to popularize green energy technology by proposing the way of easy
integration in urban environment. Integration of PV in urban environment is a
promising technology that can lead to a construction of Zero or nearly Zero Energy
Buildings. However, PV installation in an urban environment is followed by
difficulties such as lack of space, severe climate exposure and aesthetic
implementation. The most recent and relevant solution is Building Integrated PV
(BIPV), which is an installation of PV on building façades with an appropriate
aesthetics contributing to the urban environmental impression of passers-by. In
addition, it is known that in working with renewables, financial feasibility is of major
importance. BIPV cladding can substitute building material, which implies good
savings. The government of Kazakhstan aims for the share of renewable energy in
domestic electricity generation to rise to 30% by 2030 and 50% by 2050. Therefore,
this investigation aims to determine the techno-economic potential of BIPV on
façades of high-rise buildings in the city of Astana. As a case study, a student
dormitory building of Nazarbayev University is considered. The paper concludes that
the current FIT of 99USD/MWh for solar energy in Kazakhstan is too low to get
favorable Benefit to Cost (BC) ratio. However, an increase in FIT to 115USD/MWh
would lead BC ratio greater than 1 that implies that the new project could be
profitable. Furthermore, increasing the current FIT by 60%, would lead to very
attractive equity payback period. In addition, anchoring the panel in 30-degree angle
would increase the rate of solar irradiance captured, that consequently leads us to
acceptable BC ratio. This thesis project proposes a simple, but effective way to mount
PV units on a flat building wall at 30-degree angle inclined position.
