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...

Abstract Green building technologies and design-correlated choices may significantly contribute to supporting the transition toward net energy flows in built environment. Nevertheless, large discrepancies are underlined between standard simulated monitored behaviours requiring approaches able simply correlate real ones further support coherent certification and/or optimization. The paper focuss...

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. ...

We investigate data-driven, simple-to-implement residential environmental models that can serve as the basis for energy saving algorithms in both retrofits and new designs of buildings. Despite nonlinearity underlying dynamics, using Koopman operator theory framework this study we show a linear second order model embedding, captures physics occur inside single or multi zone space does well when...

In this study, a composite double-layer wallboard with shape-stabilized phase change humidity control materials (PCHCM) has been proposed for building usage. This novel PCHCM can absorb/release both heat and moisture to moderate indoor hygrothermal environment. Based on numerical analysis in an office Wuhan (30.52°N, 114.32°E), China, the effects of energy consumption environment investigated. ...

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...

The household sector in Poland consumes more than 25% of final energy. At the same time, residents reported dissatisfaction with thermal conditions during summer months. This paper details search for passive and energy-efficient solutions to improve comfort Polish dwellings. A five-story, multi-family building was selected this research. Analyses were conducted apartments located on top two flo...

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...

To evaluate the performance and energy savings of different ventilative cooling systems, three mixed forms were described most promising rule-based heuristic control criteria used as applicable strategies based on various parameters. Parametric analyses including set-points frequencies have been conducted. EnergyPlus was to perform aforementioned a typical office building. Case studies verified...

This study aims to support building energy policymaking for office buildings in South Korea through regression models by considering the global temperature rise. The key variables representing standards and codes are selected, their impact on annual consumption is simulated using EnergyPlus reference models. Then, simplified built basis of selected variables. prediction performance developed mo...
