## 4 Case Study  
The methodology presented in the previous section was used to develop an intelligent decision support system, which helps to analyse and select the most appropriate renovation alternatives, based on conflicting criteria.  
The site selected for the multi-criteria analysis of sustainable renovation project alternatives was in Ukraine and targeted reconstruction of a non-residential building into a residential building. The building is located at street Nizhniy Val, 31-A in the Podilskyi district of Kyiv, in a dense urban development; an urban structure of the district within the Central historical area. It is in the zone of regulation of category I buildings and in the archaeological protection zone, which is an integral part of the memory of monuments and history of local significance \"Historical landscape of the Kyiv mountains and valleys of the Dnieper River\", on the territory of the archaeological monument of local significance \"Cultural layer of the Podil IX-XVIII centuries\".  
The object of study--reconstruction of three floors of a brick building (out of eight floors) with an unambiguous mountain roof type with metal tiles with the maximum public dimensions in terms of 46,940 \(\times\) 9400 m, which provides a significant amount, performed by LLC \"Engineering and Construction\" in 2019 (see Figure 6). The capital building, built before 1917, with load-bearing living and transverse brick walls, 750 mm thick (external) and 620 mm (internal), overlapping over the coconut floor: monolithic on metal beams, over 1-3 floors wooden on wooden beams. Partitions--brick.  
The reconstruction is based on the following documents:  
* Order of the Kyiv City State Administration No. 506 dated 05/26/2016 on the reconstruction of the building on the street Nizhnyi Val, 31-A;
* Urban planning conditions and land development restrictions, issued by the Department of Urban Planning and Architecture of the City of Kyiv dated 24 May 2016 No. 456/16/12/2009-16;
* Design task;
* Extract from the database of the regular cadastral plan dated 2 June 2015;
* Topoplan made by the \"Kyivgeoinformatics\" Institute;  
Figure 6: Facade A-E of the building.  
* Pre-project proposals developed by Transproekt CJSC;
* Other documents.  
The project includes the exterior decoration of the house, installation of metal-plastic windows, ventilation (air conditioners), a water supply system and heating and roof tiles, in accordance with the project task. The project does not include the transfer of any structure located on the design site, as well as the removal of the existing greenery.  
The data gathered from this site were used to make comparisons between the results of this study and those of similar studies carried out by other authors. In this case study, pollution, physiological parameters of the crowd by age and gender, emotional (anger, sadness, happiness, etc.) and physiological (HRV) states of the participants were measured from September 2020 to September 2021.  
The first step was to develop a neuro decision matrix and obtain the initial data for the correlation analysis where the physiological and emotional states of stakeholders from different groups by age and gender were considered. The three categories of criteria are included in the matrix:  
* Criteria of an energy-efficient and green construction project.
* Criteria of local air pollution (CO, NO2, PM10, PM2.5) and noise levels (see Table 2).
* Criteria of the depersonalised emotional and physiological states of participants gathered in the examined site, including the states of sadness, happiness, fear, anger, disgust, surprise, valence and heart rate variability.
