Evolution of Energy Efficiency of Buildings Using the Guidelines of the European Green Deal Plan
In contemporary literature, there are not many analyses taking into account changing heat transfer coefficients over the years and examining and comparing the variability of insulation thickness in different thermal standards. The article presents the evolution of energy demand taking into account the requirements of the Green Deal. The analysis was carried out using two materials, showing how their thickness changed in relation to the evolving energy requirements. The research was illustrated with an example of thermal modernization for a building in specific time periods. The analysis was carried out using a numerical program, comparing warming variants for individual years using the Index of annual primary energy demand. Following the requirements contained in the EPDB directive, a comprehensive reduction of the penetration coefficients for building partitions was proposed and requirements for the mandatory use of mechanical ventilation and photovoltaics were introduced.
Diagnostics and Multi-criteria Analysis of Methods for Drying Buildings After Flooding. Case Study
This article presents guidelines for moisture and mycological diagnosis procedures for buildings after flooding. This paper proposes a division of the diagnostic procedure according to the medium of action and collects and presents methods for drying building elements. 54 companies dealing with drying were analyzed. The task of dehumidification is to use various methods to reduce the moisture level of building partitions to the equilibrium moisture level. An analysis of dehumidification methods in terms of ease of application, duration of the dehumidification process and level of structural interference is presented. In Poland, there are no guidelines formulated in legal acts or instructions regarding the procedure for moisture diagnostics and nor drying. It was noted that in situ studies cannot always lead to determining the actual values of mass moisture and thus to creating a real model of partition drying.
Metody obliczania studni opuszczanych
W pracy przedstawiono metody obliczania studniopuszczanych, uwzględniając metody tradycyjne oraz współczesnenumeryczne metody obliczeniowe. Omówione zostały najważniejszezagadnienia, na które należy zwrócić uwagę przy projektowaniustudni, takie jak: zapewnienie studni pogrążalności,w przypadku posadowienia w gruntach nawodnionych, zagwarantowaniestudni stateczności na wypór, zaprojektowanie podwzględem wytrzymałościowym płaszcza studni, noża studni, korkabetonowego studni oraz płyty dennej, jak również uwzględnienietechnologii wykonywania studni.
