Abstract In this study, a multi-criteria assessment approach is performed for residential apartment located in Athens, combination of different energy systems, building envelope and shading systems. 24 alternative cases total are fully simulated via EnergyPlus software aiming to the calculation Key Performance Indicators (KPIs) terms consumption heating cooling, thermal comfort, visual comfort ...

Electric appliances for cooling and lighting are responsible most of the increase in electricity consumption Karachi, Pakistan. This study aims to investigate impact passive energy efficiency measures (PEEMs) on potential reduction indoor temperature demand an architectural campus building (ACB) PEEMs focus envelope’s design construction, which is a key factor influence building’s demand. The e...

Due to increasing pressure to reduce the energy demand in buildings, thermochromic thin film based glazing has become a recognized potential solution due to the intrinsic ability to modulate the solar heat gain of a window as a function of the materials temperature. These “intelligent” glazings have been investigated for several years, and it has been found that, through variation of synthetic ...

As established by the recast of the European Union (EU) Directive on Energy Performance of Buildings (EPBD), all new buildings have to be nearly zero energy buildings (nZEBs) by the end of 2020. However, reaching this result considering cost-optimality is still an open challenge. Balancing renewable power generation with energy efficiency to reach the nZEB target is a key goal of all EU Member ...

In France, buildings account for a large part of the energy consumption and carbon emissions. Both are mainly due to Heating, Ventilation and Air-Conditioning (HVAC) systems. Because older, oversized or poorly maintained systems may be using more energy and costing more to operate than necessary, new management approaches are needed. In addition, energy efficiency can be improved in central hea...

This paper presents the first attempt to address uncertainty in zone temperature prediction with stochastic optimization. The uncertain is a process and has not been considered existing optimization for building control. To fill this gap, we proposed novel formulation of handle Specifically, examined accuracy typical linear model predicting temperature. We then formulated scheduling cooling sys...

Covered lagoon biodigesters are widely used in Brazil for treatment of agro-industrial effluents; however, under natural conditions, they operate at temperatures below the ideal. Thus, external sources heating effluent can enhance reactor performance and optimize thermal exchanges between biodigester environment. This study aimed to evaluate internal environments a covered from influence throug...

Artificial lighting can increase a energy consumption. On the other hand, the availability of daylight in occupied spaces can reduce energy consumption while positively contributing to occupant wellbeing. However, daylight entering the space through windows needs to be reconciled with heat loss during winter and heat gain during summer, which may affect thermal comfort. In this research, a gene...
