Ultra-lightweight concrete: Energy and comfort performance evaluation in relation to buildings with low and high thermal mass

The modelling gap: Quantifying the discrepancy in the representation of thermal mass in building simulation

“…The authors compared its thermal performance to conventional lightweight and heavyweight structures using EnergyPlus software. They concluded that for the case study under investigation, ULWC behaves closer to the heavyweight building in long-term heating periods and shows a relatively fast heating-up response, comparable to the lightweight building envelope in shortterm analysis [9]. Another novel approach to wall construction was investigated by Hoes and Hensen [10].…”

“…It incorporates the dynamic interactions between building design, climatic context, HVAC operation and user behaviour; hence it is considered a valuable source of information regarding the thermal performance of new building products. Roberz et al [9], performed a simulation-based assessment of the impact of ultra-lightweight concrete (ULWC) on energy performance and indoor comfort in commercial and residential buildings. ULWC is an innovative wall construction material.…”

Thermal and Mechanical Properties of Cement Mortar Composite Containing Recycled Expanded Glass Aggregate and Nano Titanium Dioxide

“…The construction industry is a potential sector for utilization of waste glass. In this regard, use of solid wastes for manufacturing the building materials with high thermal insulation properties is an effective approach toward sustainable development and decreasing the energy consumption in buildings [4][5][6]. It has been reported that the incorporation of insolation materials in the building can reduce the indoor temperature fluctuation up to 4 • C that would save 10-30% of energy usage [1,2].…”

Impact of external wall insulation thickness on internal surface temperature behaviour

“…Heat loss in the summer helps cool the interior at night. However, there is still a conclusion from the contributions [3,4] that the effect on overheating is affected by the control of building ventilation and heat gains.…”

“…The college from Eindhoven University of Technology considered the 700 mm depth ultra-lightweight concrete wall in terms of energy efficiency and thermal comfort [3]. At first, they use the periodic thermal transmittance, which combines the properties of thermal transmittance, time shift and decrement factor in one metric.…”
