Building Information Modelling (BIM) is a well-known construction technology for improving management. Its implementation in Saudi Arabia’s construction industry is increasing as it adapts to futuristic construction management practices. This quantitative case study examines the factors that led to the success of employing the BIM tool in managing a recent home development project in Jeddah, Saudi Arabia. After a survey of the available literature, 28 success criteria were identified and validated by an expert panel of 18 industry professionals. Exploratory Factor Analysis (EFA) is used to analyze data from a pilot survey of 132 people. A total of three factors are deleted because of factors leading to a value of less than 0.6. Further, there were 212 people who filled out the main survey questionnaire, and the data are analyzed using structural equation modeling (SEM). The findings show that BIM significantly improved the house development project in terms of cost, time, quality, safety, efficiency and environmental effect. Implications for management are highlighted, along with the study’s limitations and suggestions for further investigation. Overall, this research offers helpful information for residential building experts who want to make the most of BIM.

“…With a simple payback period of 4 to 5 years, the authors sized a solar PV system to provide these rationalized energy requirements using less than half the energy used before ECMs. A theoretical techno-economic analysis of the effect of changes made to the architecture of educational buildings on energy consumption was conducted in Dammam, KSA, by Hamida et al (2021). Following the implementation of all ECMs, there would be an annual energy savings of 22.7% with a 2.7-year payback period.…”

One of the primary things damaging the environment is the use of energy. In the Kingdom of Saudi Arabia (KSA), electricity is the main source of energy in educational buildings. To conserve the environment, significant efforts are now being made to reduce energy use in general and electricity use in particular. To be sustainable, it is also vital to research the possibilities of employing solar energy in the higher education sector since it is also accessible in the KSA. The main motives behind this study are the low prices of photovoltaic (PV) solar systems globally and the existence of a new government system to benefit from solar energy in the KSA. The utilization of PV solar energy at Sulaiman Al-Rajhi University in the Qassim region was examined in this article. Two scenarios were considered: scenario 1, in which the entire roof of the buildings is covered by a PV system, and scenario 2, for securing electricity so that it is a nearly zero-bill campus (nZBC). The yield factors calculated for scenarios 1 and 2 are 1896 and 1922 kWh/kWp, respectively, while the capacity factor is 21.6% for scenario 1 and 21.9% for scenario 2. For scenarios 1 and 2, the systems produce 2,160,181 and 10,199,253 kWh of electrical energy annually, respectively. The production in the second scenario is about 113% of the load to reach an nZBC, compared to the first scenario's coverage of about 24% of the load. The levelized cost of energy was found to be between 0.026 and 0.028 $/kWh, with a simple payback period of 10 years for scenario 1 and 8.1 years for scenario 2. Additionally, the proposed systems’ environmental benefits were noted.

“…A brief literature review reveals numerous recent studies have demonstrated a significant possibility of reducing energy demand in residential buildings [40][41][42][43] and educational buildings [44] in the country by energy retrofitting. For example, a study by Ahmed W. and Asif M. identified several measures that could reduce the energy consumption of residential buildings by 60%.…”

The global building sector has great potential for energy savings. Retrofitting of existing buildings can effectively improve their energy and environmental sustainability. However, retrofitting is a complex task and requires proper Measurement & Verification (M&V) to validate the process for various building types and locations. Such M&V studies for commercial buildings in the studied region are missing and a critical gap exists. This paper addresses this gap by discussing the effectiveness of retrofit energy and water efficiency measures implemented in a commercial building in Saudi Arabia. At first, a thorough energy audit is conducted and then five Energy Efficiency Measures (EEMs) and a water conservation measure is implemented. A post-retrofit M&V exercise is conducted to measure and validate the savings along with respective economic benefits. The results indicate that the implemented EEMs reduced the building’s annual energy consumption by 27%. The overall compound payback period for the investments is found to be six years. The study successfully validates the energy and water savings achievable through retrofitting by presenting the first M&V case study of a post-retrofit commercial building in the country. Thus, it proves that implementation of EEMs and water saving measures are effective strategies to retrofit commercial buildings in the region.
