For a sustainable future, energy consumption in the sector should be reduced and existing buildings need to be energy retrofitted. A number of studies present energy retrofitting of residential buildings in KSA; however, there is a lack of studies presenting retrofitting of educational buildings. Thus, the aim of this study is to adopt a BIM-based approach to assess Energy Conservation Measures (ECMs) in a prototypical Government-built educational building in Dammam, KSA. The methodology consists of six prime steps, (1) case study data collection, (2) energy auditing, (3) proposing ECMs, (4) BIM model development, (5) energy assessment, and (6) economic assessment. The energy audit revealed several inefficiencies in the building construction and operation and four ECMs were proposed and simulated. It was found that annual energy consumption can be reduced b...

The study covers five different regions in Saudi Arabia: Riyadh, Dammam, Jeddah, Tabuk and Khamis Mushait. The study demonstrates the importance of the use of thermal insulation in reducing energy consumption in Saudi Arabia. Findings showed that saving in energy consumption can reach up to 20% of the total electrical consumption. The importance of glazing area and its properties on the performance of wall's insulation was also demonstrated.

Simulations were carried out for different types of facades by using DesignBuilder 3.0 software for calculating the energy consumption. From the simulation result the best façade were selected and their economic viability was studied. It was found a significant effect on energy consumption and cooling load on the change of façade, as a result of which utility operational costs are reduced significantly. The result of the paper enables to select the optimum alternative of façade; to assist decision makers to reduce the energy consumption of buildings.

Main geometrical parameters are considered over practical ranges and common construction materials of main envelope components are addressed by parametric studies. A simple index for electrical consumption is used for comparative energy performance evaluation. The effectiveness of the different envelope constructional and geometrical parameters is investigated and their energy saving potentials are quantitatively revealed. Comparable performance improvements are shown for the geometrical parameters ranging up to 6%. Double-glazing is most effective of the glazing design with a performance improvement of up to 6%. Roof construction in general offers greater advantages of up to 10%. The application of insulation offers advantageous improvement r...

This paper examines the fundamentals underlying their structure as to how they support and interface with the available energy simulation and modeling software as well as computer systems on which they operate. The differences in TMY, TRY, WYEC, DRY, and SMY in the selection and weighting of weather parameters are discussed, outlining the pros and cons of each type. Finally, sample dry bulb temperature regimes from SMY and TMY weather files are presented to show the differences in average monthly maximum, minimum, and mean temperatures.

The dynamic impact of cultural changes on building design features, construction and operational use are identified. The resultant impacts on building electrical energy demand are analyzed using available energy consumption records and simple performance indices. The patterns of energy performance variations are explained and expected future tendencies are outlined.
