Special Issue Information

Dear Colleagues,

District heating in residential buildings consumes a large amount of energy, especially in extremely cold climate regions. Energy efficiency in residential heating is important to reduce the depletion of traditional fossil fuels, decrease global final energy use, and decrease global carbon emissions, so as to help achieve carbon neutrality in building sectors. Residential heating systems normally include heating energy supply and heating load at the end-user side. Depending on different energy sources and energy conversion processes, there are different types for residential heating, such as gas boilers; solar thermal collectors; combined cooling, heat, and power (CCHP); heat pump; among others. Normally, heating energy supply systems should be dynamically controlled in accordance with heating load of residential buildings. Real-time controls propose high requirements of fast response times without signal delay, such as iterative feedback control, PID (proportional-integral-differential) control, model predictive control, and so on. In addition, thermal energy storage can also address the mismatch between heating energy supply and heating load.

Energy-efficient heating systems, flexible heating loads, and advanced thermal energy storages are effective strategies for reducing traditional fossil fuel consumption and enhancing self-consumption of renewable energy resources (such as solar energy, geothermal energy, and so on). Furthermore, system optimization can provide multi-dimensional effective approaches in design and operation. Techno–economic–environmental analysis can provide technical viability and economic feasibility on different systems for district heating.

Considering the interest of this topic, we are organizing a Special Issue entitled “Energy Efficiency in Residential Heating”, aiming at reporting the most recent new finding from researchers and sector professionals, in the scope of the following themes.

Original manuscripts covering the following broad themes are invited from researchers and agencies, namely

  • Energy flexibility in residential heating;
  • Thermal energy storages;
  • Renewable energy in district heating;
  • Waste heating recovery;
  • Model predictive control;
  • Single- and multi-objective optimisations;
  • Techno–economic–environmental analysis.

In this study, flue gas heat recovery potential was determined by using the flue gas measurements from boilers of buildings with solid fuel-fired district and central heating systems in Balikesir, Turkey. Potential flue gas heat recovery potential in terms of energy savings were examined. The potential of heating the preheated water and combustion air supplied to the boiler was analyzed. Thus, the efficiency of the heating system was increased, and energy savings were achieved by providing fuel savings. In order to reduce the flue gas temperature in solid fuel-fired boilers, the acidification temperature, fuel properties and excess air coefficient should be known. Below the acidification temperature, corrosion and other adverse effects may occur in the flue and in the heat exchanger. In this study, acidification temperature and fuel and combustion characteristics of coal were taken into account. Generally, seven types of coal are used for heating purposes in Balikesir province. Thus, flue gas heat recovery potential was determined for these seven types of coal. In terms of energy savings, the recovery potential in Balikesir province was calculated to be between 287,706 and 152,780 kW. Full article
