Abstract
The study presents a sustainable building modernisation model that uses knowledgebased decision-making methods to general reconstruct old public buildings, intending to achieve the best level of energy use on the design scene. The rapid development and dissemination of standards cause multiple research opportunities in the fields of process automation and adaptation of BIM technologies to the prerequisites of existing buildings. Decision-making was widely supported by imitating structures used in the late stages of design. However, its application is not sufficient at the beginning, which affects design solutions with a significant impact on the performance of the completed building. Construction design is a multifaceted discipline where architects, engineers, contractors, and builders influence design decisions. This modernisation way uses digital systems and simulations to estimate the expected energy consumption of construction faster and economically. BIM and critical characteristics are the basis of the model, where design and general processing needs to follow to pre-built instructions. This solution allows estimating energy demand in reconstructed buildings and correlation of parameters.
Highlights
A more detailed analysis of the development of the construction economy shows that in the 21st century, property management has shifted from near-exceptional growth and construction consumption to critical types of sustainability, namely economic growth, social development, and environmental protection (Jia et al, 2019; Zou et al 2017)
The Energy Roadmap 2050 and 2030 EU Climate and Energy Framework insist on more focus on the energy efficiency of the housing sector due to the reason that it is the biggest user of energy in Europe, counting for almost 40% of the all energy consumption (European Commission, 2011b, 2014; European Union, 2010)
Strategic energy documents of the EU insist on placing greater emphasis on promoting the efficiency of energy consumption in the building management sector as inefficient buildings account for about 40% of consumed energy in Europe (European Union, 2010; European Commission, 2011a, 2014)
Summary
A more detailed analysis of the development of the construction economy shows that in the 21st century, property management has shifted from near-exceptional growth and construction consumption to critical types of sustainability, namely economic growth, social development, and environmental protection (Jia et al, 2019; Zou et al 2017). Buildings with zero-waste can only be achieved ensuring that design of building, construction processes and operation phase increase productivity and decreases energy consumption, use fewer resources it reduces the amount of waste and the impact on the environment as well as reduce costs during the lifecycle. The design, construction and operation of buildings shall aim to ensure full energy consumption in line with the principle of sustainable and energy-efficient development. They seek to achieve higher efficiency and lower energy consumption, fewer resources, less waste and minimal environmental impact, as well as reduce the cost of a building during its life cycle (Wang & Adeli, 2014; Žėkas et al, 2014). Hybrid MCDM approach consists of MCDM methods. Zavadskas et al (2016a, 2016b) identified four groups of hybrid MCDM methods to calculate the relative value of criteria and prioritise identified alternatives
