Simulation of Energy Consumption Changes in Residential Buildings

23.7.2018 | doc. Ing. Dalibor Vytlačil, Ph.D., ČVUT v Praze, Fakulta stavební, Katedra inženýrské informatiky, Časopis Vytápění, větrání, instalace
Energy consumption in residential buildings depends on the quality of building stock. Besides external conditions, there are two basic factors influencing future energy consumption – the technical requirements for new-built buildings and the refurbishment rate of the existing building stock. The paper presents an approach which integrates both strategies into one dynamic model. The main outputs are the amount of refurbished buildings and the energy consumption in the whole building stock. The model allows to estimate these results according to the quality of new-built buildings and at the same time it is possible to set up a strategy for the second option reducing the energy demand of buildings, i.e. the refurbishment of existing building stock. In the case of refurbishment, the key parameters for the decision about implementation of proposed improvements in buildings are usually the energy prices and the level of subsidy. Decrease in energy prices will change the financial profit from a project and it will consequently influence the owner decision about the refurbishment of a building. The model is based on system dynamics. It allows for a large scope of boundary conditions to be simulated. A sensitivity analysis has been performed on the input parameters having major influence on the owners’ decision about refurbishment of the existing building stock.

Water elements – technology and operation

23.7.2018 | Ing. Zdeněk Žabička
Historic gardens served for closed groups of people. Today, gardens and parks are mainly used by the general public, with all the negative influences that flow from it. The article also mentions requirements for technical solutions of water elements, including operational requirements.

Building Regeneration

Refurbishment of Riding`s Hall Roof Structure - The National Heritage

23.7.2018 | doc. Ing. Jaroslav Sandanus, PhD., doc. Ing. Kristián Sógel, PhD., Katedra kovových a drevených konštrukcií SvF STU v Bratislave
In the paper the refurbishment of riding`s hall roof structure is presented. The combined steel-timber load-bearing structure had visible and high horizontal deformations and the gable wall was pushed out of the building.In the frame of refurbishment the diagnostic survey, structural calculations of the original and the new stage of the structure and the proposal of refurbishment works were worked out.
