Rekonstrukce obchodního domu na Mělníku

Abstract

Tato diplomová práce se zabývá rekonstrukcí obchodního domu "Dům služeb Mělník". Cílem je rekonstrukce celého objektu a přestavba 2.NP tak, aby zde vznikly prostory pro městskou knihovnu, dětské centrum Kašpárek a prostory pro další volnočasové aktivity pro občany města. Cílem je dosáhnout optimálního řešení s ohledem na efektivní využití energií vstupujících do budovy, snížit celkovou energetickou náročnost budovy a vytvořit kvalitní vnitřní prostředí pro prostory stávající i nově navržené. Na začátku práce jsou uvedeny parametry a požadavky týkající se návrhu a provozu obchodních domů včetně uvedení příkladů vzorových staveb. Dále je uvedeno vyhodnocení současného stavu včetně vyhodnocení energetické náročnosti budovy, které dále slouží jako podklad pro koncepční řešení přestavby 2.NP a možná opatření vedoucí ke snížení celkové energetické náročnosti stavby.

This thesis deals with the reconstruction of the "House of services Melnik". The main goal is deep retrofit of second floor at the municipal library, children's center "Kasparek", fitness facilities and other services for the citizens of the city. The aim is to achieve an optimal solution with regard to energy-efficient and indoor environmental quality. This thesis consists of five parts. The first part deals with the requirements for buildings based on the functional use. Particular examples of similar reconstruction serve as inspiration. The current state of the building is described in the second chapter. There is a description of the building (information about the location of building, building information, photos and functional use), structures (building construction, windows.), and technical systems in the building (heating, domestic hot water, ventilation ....). Furthermore there is an assessment of building components and technical systems and their possible solutions with a view to improving energy efficiency and indoor environmental quality. The third chapter describes the rebuilding of the 2nd floor and other changes in the building. It is the concept of remodeling of business units at the municipal library, fitness center, multipurpose hall and a children's center with adjacent gym. Changes in the structures, windows, skylights and technical facilities in the building are also described here. The fire protection of the building is described in this chapter. Escape routes from the building are main problem. The assessment of the energy performance of the building is noted in the fourth chapter. Individual input parameters for the calculation (indoor and outdoor temperature, occupancy buildings ...) and the calculation procedure are written in the fourth chapter. The final evaluation of the current state of the building is summarized in tables (average heat transfer coefficient, energy label of the building envelope etc). Finally there are described possibilities of using renewable energy sources. They are the solar collectors and photovoltaic panels on the roof of the building. The last chapter is an overview of the various measures in alternatives A-D and compares them in terms of consumption for heating, HVAC, primary energy entering the building etc. In conclusion there is described a summary of the main objectives of the thesis, as well as recommendations for the more detailed proposal (static assessment of building structures, detailed design of HVAC equipment etc).
