摘要：Historical buildings in the centre of European cities are
characterized by compact built-up areas with diversified heights of
buildings, most often with multi-sloped roofs. Architectural elements,
dormers, chimneys and bay windows, cause limitations in the availability
of surface area for solar installations. The paper presents the results of an
analysis for possibilities in meeting energy requirements with the use of
solar energy for old-town buildings in the centre of Bydgoszcz. Based on
the calculations made, it was determined that the dense downtown
development has a very large roof surface, however, the vicinity of
buildings, roof slope angles, and obstacles cause significant restrictions on
the location of such installations. The article analyzes selected fragments of
the Downtown district. The height of buildings, their shape and the surface
of their roofs and all the obstacles that occur there were taken into account.
The conclusions concern an assessment of the possibility of using the
potential of solar energy in this type of building. The efficiency of solar
installations and the losses associated with energy conversion and
transmission to customers is also included.
