“…For the heating and cooling energy demand estimation, the EnergyPlus simulation program has been used, a tool that has been widely applied and validated by numerous scientific studies [12,13]. The plan of the investigated building unit along with the 3D model of the thermal zone and the surrounding obstacles are shown in Figure 1a, 1.b and 1.c respectively.…”

The present study aims to evaluate the effect of climate change on the heating and cooling energy needs of a residential building unit, located in the city of Thessaloniki, Greece. Future weather files have been generated using both statistical and dynamical downscaling methods. In the first case, the Meteonorm weather generator was used to generate a future weather file, while for the dynamic downscaling approach, the Hadley Regional Model 3 (HRM3), coupled with Hadley Climate Model 3 was employed. The generated future weather datasets have been then used as an input parameter in the dynamic energy performance simulations of the residential building unit with Energy Plus. For all examined weather datasets, the simulation results show a decrease of the heating energy use, an effect that is strongly counterbalanced by the rise of the cooling energy demand.

“…Their in situ measurement shows that their proposed shielding system could reduce incoming thermal energy equal to 38.7% during the summer. Queiroz et al (2020) simulated UDI range 100-2000 lux for buildings in Florianopolis, Brazil, using Radiance and EnergyPlus [11]. They used Rhinoceros 3D with the Grasshopper plugin.…”

Energy consumption is a major sustainability issue. One of the largest portions of energy consumption in buildings comes from cooling. This paper proposes the use of L-shaped minilouvers as shading, which both improve useful daylight illuminance (UDI) and reduce cooling-energy consumption. Jakarta, Indonesia was chosen as the study location since it has driving factors for higher cooling energy, ranging from those of demographic to the environment. An open office was chosen for simulation in Rhinoceros 3D with the Grasshopper, LadyBug, and Honeybee plug-ins, which utilize the EnergyPlus engine. Following the UDI and cooling-energy simulations, surveys were conducted to gather the information of the price of materials for shading and electricity. Savings from cooling energy were compared with the cost of shading application to obtain the simple payback periods. The best shading was provided by L-shaped minilouvers, which can achieve a simple payback period of 0.86 years, reducing cooling-energy consumption by around 18% while improving around 16.78 UDI in comparison with the base case with the average of all the orientations. All simulated L-shaped minilouvers also performed better than the overhang did, which is a more common form of shading in the simulated location.

“…Several methodologies were implemented to estimate energy saving, predict the specific meteorological data of the year, and needed selected building data for real-time building energy consumption, then simulating the software model using the actual power consumption [16]. Research using simulation EnergyPlus can effectively reduce energy and money consumption pointed out the appropriate orientation and lighting control [17]. Simulations were performed by using EnergyPlus in order to measure the influence of behavior patterns on the building's energy consumption [18].…”

The heating, ventilating, and air conditioning (HVAC) system consumes nearly 50% of the building's energy, especially in Taiwan with a hot and humid climate. Due to the challenges in obtaining energy sources and the negative impacts of excessive energy use on the environment, it is essential to employ an energy-efficient HVAC system. This study conducted the machine tools building in a university. The field measurement was carried out, and the data were used to conduct energy modelling with EnergyPlus (EP) in order to discover some improvements in energy-efficient design. The validation between field measurement and energy modelling was performed, and the error rate was less than 10%. The following strategies were proposed in this study based on several energy-efficient approaches, including room temperature settings, chilled water supply temperature settings, chiller coefficient of performance (COP), shading, and building location. Energy-efficient approaches have been evaluated and could reduce energy consumption annually. The results reveal that the proposed energy-efficient approaches of room temperature settings (3.8%), chilled water supply temperature settings (2.1%), chiller COP (5.9%), using shading (9.1%), and building location (3.0%), respectively, could reduce energy consumption. The analysis discovered that using a well-performing HVAC system and building shading were effective in lowering the amount of energy used, and the energy modelling method could be an effective and satisfactory tool in determining potential energy savings.
