Green Design and Sustainable Architecture
An ambitious reduction in greenhouse gas emissions is set by the political initiative “The European Green Deal” and “Fit for 55” package. The municipalities, which carry out the strategic management of the district heating systems, will have to ensure the sustainable development of the territory in a way that includes a significant increase in energy efficiency both in the building stock and in the related district heating system.
The aim of this research is to study and develop an easy-to-use methodology and an appropriate web-based application for sustainable management of the urban heating system, which would allow a quick and at the same time accurate and objective analysis of the potential and benefits of the different building renovation depths and corresponding heating system renovation variants in a given area during the pre-design stage, as well as compare them according to their efficiency.
A tree data structure is chosen as the most suitable algorithm, allowing creation of hierarchies of the necessary depth and complexity. Urban (root) level combines many renovation projects to create a dynamic functional model of the specific heating system and for initial modelling the overall impact of various renovation variants – heat consumption and primary energy savings, reduction of CO2 emissions, changes in costs and investments to be performed. At the 2nd - project level – the development of concrete projects and their options takes place. Each project option is a possible heating solution; the attributes of the option define benefits of this project. At the 3rd – component level – heat balances of components (buildings and heat system (DH or local)) are created on the basis of key data of their main elements. The last, 4th level ensures entering and editing thermal, constructive, and financial data on the main elements of heating system components.
Developed management methodology and tool based on the data from real buildings and heating systems shows achievable energy consumption and primary energy savings, reduction of CO2 emissions, takings into account heating energy tariff and renovations investments. Achieving the goal means the serious scientific novelty in the management science and evaluation of the climate policy implementation, as well as the new technological know-how and innovation in data processing.
