Buildings consume more than 40% of the world’s primary energy, of which heating, ventilation, and air-conditioning (HVAC) is the largest end use. Nowadays, more energy conservation measures (ECMs) are developed to improve the building performance and reduce energy use. Furthermore, the variations of thermal loads and energy use of HVAC in buildings are directly influenced by weather. The energy...

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...

Direct solar irradiance may cause thermal discomfort, even in winter when the ambient temperature is low and especially for high-altitude locations with a high intensity of solar radiation. Thus winter solar shading might be required and, if used, must achieve a balance between the prevention of the transmittance of solar irradiance, the utilization of passive solar heat and the supply of adequ...

Green roof and solar photovoltaic (PV) systems are two technologies that could contribute to sustainable building development and reduction of greenhouse gas emissions. When they are combined together on the building roof, it can enhance their functions and effectiveness by cooling and shading effects. This paper explains the major findings of a research to study the benefits of integrating gre...

Integrating daylight and energy performance with optimization into the design process has always been a challenge for designers. Most of the building environmental performance simulation tools require a considerable amount of time and iterations for achieving accurate results. Moreover the combination of daylight and energy performances has always been an issue, as different software packages a...

This study uses the Monte Carlo method and building performance simulations to develop an additive model for rapid peak load forecasting at design phase that considers effects of parameters. The generates numerous simulation cases EnergyPlus software is used calculations. Specifically, a total 20 parameters were considered analysing calculations, including day conditions, envelope performance, ...

Office cooling systems are controlled with on/off control according to typical occupancy patterns. During unoccupancy, the remain switched off reduce unnecessary energy consumption. occupancy, however, in operation decrease indoor air temperature, which is increased during set-point temperature. The time required temperature defined as “recovery time”. According recovery time, thermal comfort a...

The air infiltration through building envelope mainly depends on the doors and windows tightness considered by means of corresponding effective leakage areas pressure difference between exterior interior. Although standards provide simple methods to estimate parameters that control movement, significant differences in volumetric flow fresh are observed standardized most accurate traditional met...

A simulação computacional permite com que a avaliação de desempenho uma edificação seja realizada partir realidade simplificada. O EnergyPlus (EP), desenvolvido e mantido pelo departamento energia dos Estados Unidos, é das ferramentas maior destaque para este processo avaliação. Embora eficiente o se propõe, EP possui limitações no tange às estratégias otimização, parametrização identificação m...
