Historic Building Thermal Diagnostics Algorithm Presented for the Example of a Townhouse in Lviv

Abstract

This paper presents a proposal for a historic building thermal diagnostics algorithm for the example of a historical townhouse located in Lviv, Ukraine. The authors proposed a testing and diagnostics procedure that should precede design and renovation work associated with improving the energy standard of the buildings under discussion. The procedure was presented using a case study of a selected historical building. The scope of the study included an assessment of the building’s technical condition, thermal vision diagnostics, wall moisture, and water absorption in the context of protection against rain. Sample thermal and hygrothermal calculations were performed for a sample architecture element. The calculations included simulations of partition envelope behaviour after planned thermal retrofitting had been carried out. Performing the presented thermal diagnostics methods in three interlinked blocks (A, B, and C) shall ensure the proper thermal retrofitting of historical buildings in the context of their further occupancy.

Thermovision analysis of heat and power plant chimneys technical condition

“…Historical buildings conservation guidelines are very demanding in terms of renovation of the facades or thermal retrofitting of walls. The undertaken analysis show that internal insulation improves the thermal parameters of walls but unfavorably affects conditions within thermal bridges [6]. Thermal imaging testing verified the undertaken numerical analysis and was suggested as a part of the pattern that should be taken in any historical buildings for the assessment of the extant state and modernization of Lviv's historical architecture in this particular article [6] but also as reference for similar buildings.…”
