AB  - The population in Serbia predominantly lives and works in traditional buildings from the middle of the last century. This paper investigates the indoor thermal environments in two business offices in the same building, located in Belgrade, Serbia. They are approximately the same size, on the same floor, but on the opposite sides of the building. In Office 1, the exposure to direct sunlight is for about one hour in the morning in winter period, due to the NE orientation. Office 2 is SW oriented and exposed to sunlight starting from 12.30h until the sunset. The study was carried out in a traditional office building from the middle of the last century, with typical walls without insulation. Physical parameters such as air temperature, measured by K-type sensors (TK1 and TK2), relative air speed, and relative humidity are the main factors that influence the indoor thermal environment. Results regarding the thermal comfort indices, PMV and PPD, were obtained by measurements, which were performed one time per day, during the working hours, at noon, in order to get the relevant conclusions with respect to the orientation and  sunlight exposure of the offices. Other physical parameters mentioned above were measured three times per day, at two heights. In this work, the results of measurements of PMV and PPD for the whole heating season are presented.

AB  - Global warming and ozone depletion issues have had an impact on novel approaches of integrating some of
the energy production systems. In present, fossil fuels such as oil, coal and natural gas still are the primary
sources of energy used to provide the majority of the cooling requirements in vapor compression systems. In
addition, this high energy-consumption systems work with substances that contribute to ozone layer depletion
and are typically based on fluorinated gases (F gases), that as well, can have a global warming impact
thousands of times greater than CO2. Much research has been done on reuse and waste heat utilization within
different systems to achieve a reduction in high carbon fuel consumption. The method that aims at improving
the value of the exergy of the available renewable energy sources is the absorption refrigeration cycle (ARC).
With ARC, the concept of “cooling with the heat“ can be achieved, with a variety of benefits such as integration
of the energy production systems, implementation of sustainable based technology in the industry of cooling,
the possibility of establishing a district cooling system, etc. The cooling demands can be met through utilization
of solar radiation, energy from biomass, waste heat from industrial processes, geothermal energy.
In the terms of the importance of low-temperature heat sources and the reuse of heat energy, currently present
researches have focus on identifying engineering and cost-effective approaches to enhance the efficiency of
an integrated system. That kind of system affects the output parameters of energy production and energy
consumption, so the possibilities to compare the different systems from the exergy and economic standpoint,
based on the different parameters are vast. The criteria of comparison and investigation the effects of
integrated systems in majority of cases would be based on: better performance at very low temperatures,
carbon dioxide emissions and cost savings. Despite the existence of different obstacles, the integration of
different energy production systems will have a considerable impact when it comes to overcoming the
challenges in the energy sector.
