The latest revision of national standards, aimed at the thermal performance of structures, conformed to internationally applicable standards of energy-efficient construction, low-energy construction, ultra energy construction, and nearly zero-energy construction. This paper analyzes the requirements of thermal revised standards in the context of the construction of apartment buildings. The mentioned required standards involve improved and more detailed project planning, leading to the comprehensive realization of building projects as they are intended. Currently, in addition to traditional ways of building, there is an increasing prevalence of modern methods of construction. MMC are using the potential of prefabricated parts of structures. In this article, the aforementioned methods will be compared from an energy conservation and economic point of view.

The aim of the paper is to present the results of a comprehensive analysis of three selected wood-based construction systems from design, technological and economical point of view. The selected construction systems imply the stick frame construction system, the structural insulated panels and the standard panel construction system. The optimal construction system from the perspective of a customer is evaluated on the basis of the multi-criteria optimization method. The typified design of the family house Largo 85 served as a model to present and analyze the parameters such as construction cost, construction time, heat transfer coefficient of external walls and air soundproof of walls. The mentioned criteria are the most significant for a customer when making a decision about the most suitable wood-based construction system.

Construction industry has a large share in environmental pollution. In the context of building industry, it is also the transport of building materials and products, which largely contributes to environmental degradation. Construction increasingly promotes wood-based construction systems, thanks to faster construction, better environmental, energy and economic parameters. Prefabricated wood-based panel construction system fully utilizes construction, manufacturing and assembly advantages of the production to the efficiency of the entire construction process. The key moment to increase the efficiency and degree of prefabrication is panel’s finishing. Creation of structural elements in the factories allows a reduction in rides to the site. The paper analyzes the transport costs of the model house constructed by the system of traditional brick and panel system based on wood in the context of transport and manipulation of materials in both bearing systems.
