Предизвикателства при проектиране, изграждане и експлоатация на пасивна сграда в България

Challenges to the Design, Construction and Exploitation of a Passive Building in BulgariaThe construction of buildings that have to achieve the idea of a sustainable and energy-efficient construction sector requires a study of passive buildings. Specific requirements for the design, construction and exploitation of a passive building leading to limited flexibility in terms of heating, ventilation and air-conditioning, renewable energy, modern know-how, the introduction of highly efficient building systems, the lack of experience of Bulgarian producers present the relevance of the topic and justify a more detailed study. The aim of the article is to analyze the challenges in the design, construction and exploitation of the passive building in Bulgaria and on this basis draw generalized conclusions and make recommendations for improving the implementation of projects according to the Passive House Standard. The content of the article is structured as follows: 1) Literature review of technological features in the design, construction and exploitation of a Passive House; 2) Methodological framework of the study; 3) Assessment of the challenges in the design, construction and exploitation of a passive building in Bulgaria; 4) Summary of the results and recommendations. The last part of the article summarizes and recommends the challenges of implementing this type of projects related to the characteristics of the construction’s technologies and conditions for exploitations.
