Buildings are responsible for almost forty
percent of global energy. Due to their high consumption of energy, buildings
are on the front line of sustainability researches. In Turkey, six million out
of twenty-two million buildings need to be demolished and rebuilt to meet
seismic standards. These buildings are also far below the standards in terms of
energy efficiency. Therefore, urban transformation can be thought of as a great
opportunity for energy efficiency. This study investigates four things: (i) the
energy-efficient urban transformation strategy in Gaziosmanpaşa-Istanbul
region, which is selected as a case study; (ii) the effect of energy efficiency
in this market; (iii) the adequacy of energy standards of Turkey; and (iv)
contribution of digitalization in construction to sustainability with Building
Information Modelling (BIM) and energy analysis. According to the energy
efficiency scenarios, energy analyses were carried out on the BIM model. The
most cost-effective strategy was determined with the Life Cycle Cost method. When
compared with the current situation, it is possible to save energy up to 227
GWh a year, which is equal to the annual heating energy demand of approximately
30,000 housing, in the case study area with the most efficient scenario to be
realized.
