| Abstract [eng] |
Cities are the engine of the economy. Population in cities is projected to reach 70% in the coming decades. Therefore, it is normal that a smarter, more economically productive cities needs smarter and more efficient buildings that provide more opportunities for higher income generation at company and country level; greater competitiveness. On the other hand, buildings use more than 40% of the world's primary energy and produce 24% of greenhouse gases. Buildings are also big users of water, materials and land. Thus, reducing the environmental impact of buildings is a priority when addressing climate change and other sustainability challenges. Meanwhile, smart buildings contribute to the perceived quality of life, preserve scarce resources and integrate single systems into one whole. Research has shown that properly constructed buildings can boost employee productivity. It can be argued that the development of smart buildings not only contributes to the practical implementation of the smart city concept, but also contributes positively to the urban and national economy and, above all, to the perceived quality of life of the population. At the same time addressing global challenges: reduce CO2 emissions; use resources efficiently and sustainably. The object of paper – real estate development model in smart cities. The aim of paper is to develop a theoretical model for real estate development in smart cities. Tasks: 1) review the concept and main characteristics of a smart city; 2) review systems for assessing of smart buildings; 3) to evaluate ten buildings according to constructed theoretical model of real estate development. The theoretical model of real estate development in smart cities created the preconditions for comparing 10 buildings: 5 abroad and 5 in Lithuania. Buildings are compared in 5 stages: 1) idea generation; 2) pre-design stage; 3) designing; 4) construction; 5) operation and maintenance. |
