Sustainable building practices can considerably reduce building’s environmental impact in energy consumption. Covering a building envelope with green vegetation, such as green roof and green wall, is considered a sustainable construction practice, as green vegetation has a positive performance in energy savings. It reduces heat flux and solar reflectivity, generates evaporative cooling, increas...

This paper investigates the interaction between supermarket heating, ventilation and air conditioning and refrigeration systems through simulation in EnergyPlus. This interaction has been studied by modelling a generic UK supermarket. The impact on the sum of HVAC and refrigeration energy consumption due to changes in a range of operating conditions was studied. These include the effect of alte...

Radiance matrix-based methods enable efficient parametric simulations, allowing users to vary sky conditions, fenestration systems, and other model parameters at a minimal cost computation. However, the steep learning curve complex workflow hinder widespread adoption of methods. The frads Python library with series command-line tools was developed automate entire simulation process, lowering en...

As high performance design is becoming more desirable in the field of architecture, the need for supporting architects with environmental analysis tools is also growing. Rhino/Grasshopper is one of the most widely used platforms that are used by designers today. There are already a number of environmental plugins developed for Rhino/Grasshopper. However, Ladybug offers several advantages that a...

This paper proposes and demonstrates the effectiveness of an economic model predictive control (MPC) technique in reducing energy and demand costs for building heating, ventilating, and air conditioning (HVAC) systems. A simulated multi-zone commercial building equipped with of variable air volume (VAV) cooling system is built in Energyplus. With the introduced Building Controls Virtual Test Be...

Based on the building of a kindergarten in Weinan, Shaanxi Province, this paper explores influence different envelope structures and heating modes indoor thermal environment for energy saving comfort existing buildings. Using operating temperature as evaluation index comfort, 15 designed schemes were simulated through Energyplus software actual measurement to obtain change law annual consumptio...

Bioclimatic solar greenhouses are passive systems of relevant interest in the building sector, as they allow reduction energy needs related to air-conditioning. The aim this work is analyze thermal behavior a bioclimatic greenhouse attached residential building. It equipped with photovoltaic blinds (SPBs) manage inputs and produce electricity. Automated control implemented activate vents SPBs. ...

Abstract Building surface reflectivity determines the amount of reflected solar radiation, which indirectly affects cooling and heating load a building. Therefore, optimizing building retro-reflectivity is an effective method to reduce energy CO2 emissions buildings. To analyse optimization potential retro-reflectivity, effect on daily, monthly yearly load, as well educational were simulated ba...

Recently, expanded metal mesh has been used on the facades of many buildings in Taiwan. Therefore, this study, we evaluated impact natural lighting and energy consumption office buildings. First, compatibility EnergyPlus DIVA simulation software with was verified using field measurements. The results show a high correlation between measurement, except for some periods direct sunlight. Then, eff...
