Low energy buildings require an efficient thermal insulation of the envelopes ensuring minor heat losses; such buildings must be tight in order to avoid heat losses due to over-infiltration. Installation of a heating recovery system compensates for some heat used for heating the ventilation air. The design solution of transparent envelopes of low energy buildings determines significant solar heat gains that compensate for a part of heat losses through the envelopes and ventilation systems. Taking into account these properties of low energy buildings, the modeling of indoor temperatures of such building was carried out at varying outdoor temperatures and power of the heating system. On the grounds of the obtained results, it was determined that a lower heat source power than the one determined according to the outdoor temperature of the coldest five-day period can be used to meet the indoor microclimate requirements in a low energy building. In this way, the expenses of heating system installation are reduced and the operational efficiency of the heat source is increased.

Abstract The publication presents a design solution for circular multi-pipe thermal insulation and an example of an existing heating installation consisting of six individual heating pipes in the building of the Bialystok University of Technology. In the paper, the arrangement of six heating system pipes in circular thermal insulation was designed in such a way that one heating pipe is centrally located in the circular thermal insulation, the other five heating pipes are located at the vertices of a regular pentagon inside the circular thermal insulation. Heat loss calculations were made using the Boundary Elements Method (BEM) with the actual boundary conditions in the room where the existing heating installation is located. Additionally, the ecological effect was determined in the form of reduction of pollutants emitted into the atmosphere resulting from heat losses for the developed multi-pipe thermal insulation. The calculation results showed a significant reduction in heat losses as a result of the use of multi-pipe thermal insulation in relation to the existing single heating installation. The use of multi-pipe insulation undoubtedly follows the trend of energy-saving heat transport and is an alternative to the commonly used single pipes.

Abstract The heating and cooling of buildings with large-scale ceiling systems nowadays is widely used in traditional as well as in new, low-energy buildings. This type of system is being employed in a building of the Civil Engineering Faculty (FCE), Slovak Technical University, in Bratislava. The building’s refurbishment in 2010 included the complete replacement of the building’s envelope. The replacement is a lightweight facade with a high percentage of transparent construction. Due to the differences between the type of envelope and the heating system, the operation of the heating system frequently causes thermal discomfort, especially during warm spring or autumn days. The aim of the measurements was to evaluate the control of the operation of the heating output, the appropriateness of the location of sensors measuring the outdoor temperature and possible improvement of the current control system to improve the heating system’s quality.

Low Energy Buildings

Passivhaus or Passive House buildings are low-energy buildings in which the design is driven by quality and comfort, hence achieving acceptable levels of comfort through post-heating or post-cooling of fresh air. Additionally, Passivhaus building design follows the Passivhaus design criteria, as described in the Passive House Planning Package (PHPP). This article aims to introduce the Passivhaus background, development, and basic design principles. Finally, it also presents a brief description of the performance of Passivhaus buildings.
