The building sector is one of the crucial stakeholders in global energy and environmental scenario. Life cycle assessment (LCA) a tool widely used to evaluate performance buildings, materials activities. Saudi Arabia has rapidly growing construction with over $1 Trillion ongoing projects. housing sector, annually needing 2.32 million new residential units coming years, yet entertain buildings its list priorities. present work undertakes LCA study three-bedroom modern villa located Dhahran....

The application of renewable energy has been an integral part the sustainability drive in building sector and solar photovoltaic (PV) is one most effective technologies this respect. present study aims to investigate prospects PV residential buildings hot–humid climatic conditions. discusses utilization roofs for terms potential hurdles factor (UF). Technical performance systems also investigated power output as well saved a result shading impact panels two types units, apartments villas....

To meet the increasing energy demand and to shave peak, Kingdom of Saudi Arabia (KSA) is currently planning invest more on renewable (RE) seeking diversity resources. Through integration demand-side management measures distributed generation (DG) systems, study outlined in this paper aims at investigating potential hybrid systems supplying demands for residential communities an oil-rich country. The community considered study, located eastern region KSA, has annual electrical usage 1174 GWh...

Purpose This study aims to evaluate the quality of an on-campus medical facility at a leading university. Design/methodology/approach Published literature was consulted review knowledge areas on usability and performance requirements healthcare facilities. Quality indicators were, thus, developed from extant verified by walkthrough case facility. Then, assessment survey administered obtain feedback users Additionally, focus group meeting conducted more qualitative issues identified through...

The commitment of electrification and decarbonization goals in the United States (U.S.) will significantly change performance future buildings. To meet these goals, it is critical to summarize existing research related building discuss pathways. This paper provides a perspective on pathways buildings U.S. A review was conducted, which divided into three closely linked categories: technologies, economic impacts, code regulations. Technologies support investments regulations while marketing...

The Gulf Cooperation Council (GCC) countries have over 50% and 30% of global oil gas reserves respectively therefore traditionally relied on fossil fuels to meet all their energy requirements. In recent years however there has been a realization diversify mix tap rich solar potential. While buildings account for as much 80% the total national power generation in these countries, emphasis thus far large scale projects. article examines prospects application PV building by undertaking...

Saudi Arabia is experiencing a rapid growth in energy demand as result of burgeoning population, modernization and economic development. The building sector has an import role this respect it accounts for almost 80% the total national electricity consumption. Following global trends, also resorting to high rise glass facade buildings especially commercial sector. Sustainability aspects such terms environmental impacts, however, have not been duly addressed Kingdom yet. This study undertakes...

Abstract Switchable building envelope systems, including passive and active have recently seen an increase interest in the literature. Unlike static insulation, switchable insulation systems (SISs) ability to adjust thermal properties of elements. Advanced control strategies for SISs are evaluated this analysis using genetic algorithm-based optimization techniques. In particular, study investigates potential heating cooling energy savings deploying optimal controls specific SIS technologies...

Abstract In this paper, the energy efficiency potential of applying novel dynamic insulation systems to slab foundations is investigated for residential buildings. Specifically, allows foundation change its thermal resistance reduce both heating and cooling loads compared static systems. The benefits are evaluated using a validated numerical model integrated with state-of-art whole-building simulation tool. optimal settings slab-integrated determined monthly while maintaining comfort...

Abstract In this paper, the energy benefits of dynamic photovoltaic (PV)-integrated overhang systems are evaluated for office buildings. The PV-integrated overhangs combined efficiency by decreasing both heating and cooling demand on-site renewable power generation deploying tracking PV panels. performance is considered various design operation conditions. Specifically, impacts features such as depth, window size, glazing type, heating, ventilation, air conditioning (HVAC) system type....

Awareness of how buildings interact with the occupant experience—especially human productivity—is becoming more prevalent, as seen by increasing interest and investment in healthy built environments. However, there has been little previous work translating quantitative indoor environmental assessment productivity research to building operation. The that does exist typically focused on a single metric, combined disparate metrics types, not making results utilizable practitioners. This...
