The present study has focused on the impact of location and deadband (range of thermostat setpoints for cooling and heating) on the energy performance and economics of nano granular silica aerogel (nanogel) glazing in a multi-storey office building, by considering 26 climatic locations of Saudi Arabia. The selected cities were classified according...
This article evaluates the thermal and energy performance of mortar blocks containing local agricultural waste. The mortar blocks were cast by the replacement of ordinary Portland cement (OPC) with varying amounts of date palm ash (DPA) in the range of 10–30%. Experiments and simulations were carried out to assess the thermal characteristics and en...
Energy consumption in the building sector accounts for a large percentage of global energy consumption. For this reason, it is essential to take action to minimize this destructive consumption and promote energy conservation practices within the building sector. A Zero Energy Building (ZEB) concept has been proven as a viable technique for improvin...
In hot and humid climates, a significant part of the energy is used to cool the building. There are several ways to reduce this air conditioning load, but one standout is through the selection and design of the right building envelope and its components. The thermal characteristics of the building envelope, in particular the thermal resistance of t...
Thermal insulation of wall and roof and high-performance glazing have potential to save energy in cooling-dominated climates. However, lack of careful selection of these options based on the climatic location can adversely affect their energy performance. The local building codes need to be revisited to ensure that the thermal insulation and glazin...
High energy consumption has far-reaching consequences for the natural world, including the acceleration of climate change, the acceleration of environmental deterioration, and the acceleration of air pollution caused by the combustion of fossil fuels to generate electricity. However, there are still many obstacles to implementing the nZEB idea, not...
Sustainable materials present a significant revolution in the construction industry and exhibit tremendous potential to develop a green building material that can be adopted to lower the construction sector’s carbon footprint. This study details the development, mechanical and thermal properties of mortar produced using biochar derived from date pa...
In this study, three types of cellulose nanocrystals (CNCs) of varied crystallinity (79.91–89.31%), diameters (of 0.1–1 μm), lengths (of 0.8–10 μm) and synthesized at solid to acid ratios (of 1g:20ml to 1g:25ml) were incorporated as a green additive (0–1.5%) in the preparation of cement mortar. The performance of the developed mortar was examined b...
In recent years, nanotechnology has become an essential means of producing sustainable and engineered materials, resulting in high value-added products in the construction industry. Nanostructured cellulose (NSC) is a next-generation sustainable and eco-friendly material due to its favorable physicochemical characteristics for various construction...
The building construction sector in the Kingdom of Saudi Arabia (KSA) is the largest and fastest in the GCC states. Building Envelope has a major role in deciding the cost and energy performance of a building. As far as KSA is concerned, application of life cycle costing (LCC) technique, which performs the cradle-to-grave assessment of a building,...
Saudi Arabia is considered as the largest Muslim country that witnesses high demand on construction of new mosque buildings. This demand is emerged from the rapid booming in the construction of new residential buildings. The revolution in construction results in increasing of domestic energy consumption which consequently increases the environmenta...
The construction industry is one of the ever
growing and leading sectors, which contributes to the economic
growth of any nation. One of the current challenges in this
industry is to ensure compliance with the norms and standards
pertaining to the construction process, building quality,
performance, and most remarkably, the environmental impact.

This paper aims to examine the energy performance of a multi-story education building in Saudi Arabia, by changing the settings of façade, keeping other parameters (orientation, HVAC systems illumination load, etc.) at their standard values. Simulations were carried out for different types of facades by using DesignBuilder 3.0 software for calculat...
