To support decision-making in the design process of the energy renovation of office buildings, energy simulations are increasingly being used, and the process itself is supported by the BIM environment. The topic is highly interdisciplinary, it is under development, so any inappropriate allocation of project roles and inappropriate project and information management can lead to a substandard treatment of the building. This often leads to unsatisfactory results of the project, re-works, errors, delays and increased investment.
The dissertation introduces an information modelling methodology for the energy renovation of office buildings that is based on a progressive approach to analyses according to the building typology. This approach represents gradual model detail development according to the project phase, analysis, level of information details and goals of the project. The methodology is integrated into the proposed process map in which data flows between the stakeholders in the project are defined. The design process is supported by a qualitative analysis of the estimation of effort for obtaining additional data for additional analyses and its impact on the analysis from the aspect of costs, simulations and accuracy. A system of qualitative and quantitative performance indicators enabling the comparison of different approaches has been developed to evaluate the performance of the energy renovation design. The validation of the progressive approach was carried out on the basis of the original methodology and compared with the actual approach used.
The proposed progressive methodology improves the design control and increases the efficiency of the design process, more accurately predicts energy consumption, reduces investment costs, avoids design errors and delays in construction. The dissertation represents progress in the field of energy renovation design and supports architects and engineers in aligning customer requirements with project plans and results by clearly defining information requirements with respect to the end goal.
