“…Several studies have investigated the effect of different facade and building envelope solutions on the energy performance and indoor climate conditions of office buildings over the last years [6][7][8][9][10]. Majority of the previous studies have focused on measures applied in office buildings located in hot or intermediate climates, where the dimensioning and operation of air-conditioning systems is one of the essential factors in office buildings, when energy performance, indoor climate conditions and performance of workers are discussed [8][9][10][11][12][13]. Typically improved indoor climate conditions lead to increased energy consumption in office buildings and it is challenging to improve the energy performance and to decrease the environmental impact of buildings towards low-energy, low-carbon and nearly zero-energy buildings, and to provide productive and comfortable indoor climate conditions at the same time [10][11][12].…”

The paper presents cost-optimal renovation solutions and economic viability of different renovation measures to maximize environmental performance, thermal comfort conditions and productivity of workers in office buildings built in the late 1970s and 1980s in cold climate regions. The study also analyzes optimal combinations of renovation measures and HVAC system set points to maximize thermal comfort conditions and productivity of the building users. The productivity loss caused by unfavorable indoor thermal comfort conditions was integrated in the LCC analysis (15-year life-cycle period) of the study using an appropriate method to estimate the amount of lost performance of workers caused by the productivity loss. Simulation-based multi-objective optimization analysis was used as the research method of the study. Environmental impact of the renovation measures was studied by assessing the CO2 emissions of the delivered energy consumption. The results demonstrate that as high as 65% return on investment and 63% reduction in the CO2 emissions of operation can be achieved in owner occupied office buildings, when both the energy efficiency and the thermal comfort conditions are cost-optimally improved simultaneously. According to the results, the cost optimum energy production system concept is a ground source heat pump system used for combined heating and cooling.

“…Although large windows are interesting, the resulting excess daylight can cause glare in the administrative environments, increasing the thermal load in summer and producing thermal losses in winter. Within the context of the large glazed plans [7], in a study for Belgrade, characterized that a glazed façade can provide double solar gains compared to a Traditional Façade. From these considerations arose the research questions that this article sought to answer: Is the model used in the Federal University of Rio Grande for the new administrative buildings adequate considering the thermal-energetic performance, even though located in different orientations?…”

Daylight is a fundamental element to obtain built environments that promote environmental comfort and energy efficiency. However, strategies that enhance the building daylight performance can affect its thermal energetic performance. In this sense, research that addresses these aspects at the same time is considered essential. The objective of this paper was to evaluate the daylighting and thermal-energetic performance of administrative environments in a public institution, and to propose strategies that will enhance the use of daylight and lower energy consumption. Therefore, for future projects, and considering new buildings, and retrofit, this research will be an important reference. The research was developed through a case study of an administrative building model, in which the characteristics of solar orientation, light shelf use, glass type, and light and dark colors in walls were modified and combined, deriving it into models proposed. The daylighting performance evaluations were performed through dynamic simulation with the Rhinoceros for Diva software, and the thermal-energetic performance evaluations with the EnergyPlus software. The results of the work showed that a suitable solar orientation has a great impact on the automation of daylight and the energy consumption of the evaluated models, followed by the type of glass and the use of the light colors in internal walls, and that the use of artificial lighting with dimerization is fundamental as a complement to the daylight autonomy. For the boundary conditions of the study, the use of light shelves modified neither the daylight performance nor the thermal-energetic performance of the evaluated models.

“…Research on energy consumption in buildings has shown that much of the environmental impact of а buildings (about 80%) is due to the use of the buildings [11 -12]. Energy efficiency is also discussed by many local authors who analyze buildings in Serbia [13][14].…”

The aim of the research is to obtain optimal ranges of thermal envelope for the desired energy classes, which will contribute to a more economical and rational approach to the design of buildings, as well as to prove that with the increase of thermal envelope there is an increase of the energy class. The model on which the research was formed and applied is a typical semi-detached house in Belgrade. By comparing the results of the reference family house, the framework parameters for the satisfaction of a certain energy class have been formed, based on the fulfillment of the energy efficiency requirements established by national regulations.
