The use of VRF system and insulation in building envelope are both considered as promising option to reduce energy consumption a building. This study analysis saving potential using modelling simulation typical office model is simulated with the weather Hyderabad, Sindh, Pakistan EnergyPlus software. cases include conventional air conditioning systems without evaluate compare annual cooling sav...

This study determines the optimum insulation layer thickness to be applied external building walls considering heating degree-day (HDD) method, then energy saving costs, payback periods, and carbon dioxide (CO2) emissions are calculated accordingly. The optimisation analysis is performed for four different thermal materials (glass wool, rock extruded polystyrene, expanded polystyrene). Natural ...

This article discusses an express control method that allows in situ measurements of the thermal conductivity insulation materials. Three samples most common materials, such as polyurethane, extruded polystyrene, and expanded were studied. Additionally, optical organic glasses investigated materials with a stable value conductivity. For measurement conductivity, device, which implements differe...

Abstract Expanded polystyrene (EPS) geofoam is one of the lightweight materials used in civil engineering applications. Present study deals with application retaining wall as a backfill. In this study, two-dimensional finite element software to simulate geofoam. A 6m height considered. Lateral pressures and surface settlements are examined for various orientations Orientations include upper tri...
