We calculate insulation thickness in accordance with the criterion of maximum heat loss and monitor unwanted warming or cooling media and maintain the required temperature.

This article reflects the author's view on the issue of emissions from the combustion of solid fuels in small combustion appliances and theirs decreasing by subsidy for boilers’ change. For maximum efficiency of subsidies, author recommends: 1) replace old boilers with modern gasification and automatic boilers, 2) subsidize only boilers certified by independent accredited laboratory, 3) optimize settings of newly installed boiler according to the measurement of flue gas composition and efficiency, directly at the new operator, 4) periodically check emission parameters in real conditions.

Article is dealing with gasification principles and gasifiers. Gasification is process for gas producing from solid fuels (coal, wastes, biomass). Producer gas can be used in cogeneration unit (piston engine or combustion turbine) for generating of heat and electricity with higher efficiency in comparison with combustion in boiler. All processes in gasifier taking place with regulated supply of gasification media (air, oxygen or steam) and reaction heat.

The article describes the transmission grid of the Czech republic and continental Europe.

The article deals with the beginning and development of the energy transmission system in the Czech republic and Slovakia and it's integration to the continental transmission grid.

Methods of cost allocation in apartment buildings have undergone significant changes in recent years. The article offers a comprehensive overview of cost allocation methods in multi-dwelling units according to applicable regulations. It is intended mainly for owners of residential units, board members of homeowners associations, managers of housing cooperatives or individuals and companies managing residential buildings.
Cost allocation in apartment buildings is currently governed by two laws: Act No. 67/2013 Coll. and the new Civil Code No. 89/2012 Coll. These laws governed cost allocation in calendar year 2014 and apply also for 2015. The heating and hot water supply costs in MDUs from 2016 onwards will be allocated pursuant to the new decree No. 269/2015 Coll. and the amended Act No. 67/2013 Coll.

The aim of electricity distributor is that customers may be sourced if a constant amount of energy. When properly appliances division into groups according to how they can be turned off, it is possible to reduce the agreed value of the load shedding and save on fixed fees. The regulator load shedding so in the short term applies.

This article analyzes the causes due to which the subscribers disconnected from district heating. It also offers cheap technical solution which will bring genuine increase in energy efficiency to which we are committed (EU Directive 20-20-20).

In a previous article we described current problems of district heating. Their creation is shared by all stakeholders - customers, suppliers and the state. The only difference is that while consumers and suppliers are more or less at the mercy of events, the state is the one who will decide on the future success or failure of the sector. And in this role still failing. The state should support the heating industry, but instead he openly harms.

The amount of heat consumed by households for heating will continue to decline. The causes of this trend, we can identify more, but they all have one common feature - the growing cost of heat. It is growing because of rising prices of inputs (raw materials, technology, labor) but also due to decreasing consumption of heat (climate change, saving measures).

In the presented article is analyzed aging of the photovoltaic power plant panels located in Dukovany. Photovoltaic power plant in Dukovany (identified also as PV power plant) is the oldest PV power plants built in the Czech Republic. PV power plant was put into service in 1998. After 17 years of working is slowly ending its life. This work compared an electricity production in individual years, decreasing of produce energy from the values given by the manufacturer and also describing visible defects on selected modules.

The heating period 2014/2015 in Prague based on the observation of Prague-Karlov station was with 222 days, a little shorter, and with an average temperature of 6,4 °C, slightly warmer than the long-term average. Basic characteristic of heat demand for heating is 2803 D°(19) degree days, heat demand is much lower than the long-term average of 3227 D°(19). It's the second lowest number of degree days of the heating period since the beginning of the century.

The last time we meet with the requirement to improve energy efficiency practically every step, as a result of the implementation of Directive 2012/27/EU into our legislation. The purpose of this regulation is to cause such changes in society and in the energy sector to increase energy efficiency in 2020 by 20% and created the conditions for its further growth in the longer term. The most important area in terms of energy consumption includes heating of buildings.

The article deals with the change of the basic standard for flue gas of heating appliances. It draws attention to the illegality of technically unjustified distances between flue outlets on the facade and windows or other building openings. The specified distances lead to practical ban on installation of considerably cheaper gas boilers with the flue gas outlet through the facade.

The new rules replace the TPG 605 02 from 9. 9. 2008. A brief abstract of the law contains only general requirements and building part.

The new rules replace the TPG 609 01 of 9. 12., 2009. A brief abstract of the law contains only general requirements and building part.

Article freely continues the theme of thermodynamic analysis of phenomena occurring in and around the pipeline construction, located in the sandy backfill, now with respect to theoretical foundations, describing the related effects of heat transfer. The article includes in particular the currently known insights into heat exchange in the case where the thermally insulated pipes placed near each other in the soil backfill. Individual processes intended to evaluate size of heat loss are used in the model calculation example a specific pipeline, whose real insulating state has previously been verified by measurement.
