Alternative energy resources have a significant function in the performance and decarbonization of power engendering schemes in the building application domain. Additionally, “green buildings” play a special role in reducing energy consumption and minimizing CO2 emissions in the building sector. This research article analyzes the performance of alternative primary energy sources (sun and hydrogen) integrated into a hybrid photovoltaic panel/fuel cell system, and their optimal synergy to provide green energy for a green building. The study addresses the future hydrogen-based economy, which involves the supply of hydrogen as the fuel needed to provide fuel cell energy through a power distribution infrastructure. The objective of this research is to use fuel cells in this field and to investigate their use as a green building energy supply through a hybrid electricity generation system, which also uses photovoltaic panels to convert solar energy. The fuel cell hydrogen is supplied through a distribution network in which hydrogen production is outsourced and independent of the power generation system. The case study creates virtual operating conditions for this type of hybrid energy system and simulates its operation over a one-year period. The goal is to demonstrate the role and utility of fuel cells in virtual conditions by analyzing energy and economic performance indicators, as well as carbon dioxide emissions. The case study analyzes the optimal synergy between photovoltaic panels and fuel cells for the power supply of a green building. In the simulation, an optimally configured hybrid system supplies 100% of the energy to the green building while generating carbon dioxide emissions equal to 11.72% of the average value calculated for a conventional energy system providing similar energy to a standard residential building. Photovoltaic panels account for 32% of the required annual electricity production, and the fuel cells generate 68% of the total annual energy output of the system.

PurposeSeveral studies have shown that climate change is a threat to sustainable human living and high consumption of energy by buildings is a contributory factor. However, green practices in buildings have been proved as one of the successful technologies to mitigate global warming. Previous studies have shown lax green practices in developing countries’ buildings, but how far concerning green certification of buildings in Nigeria is yet to be explored. Therefore, this paper investigated the barriers to green certification of buildings (GCB). Also, the paper proposed a model for promoting GCB in Nigeria.Design/methodology/approachEighteen experts with green building certification knowledge were engaged across three of Nigeria’s cities (Benin City, Abuja and Lagos) via scheduled WhatsApp video and teams calls. Collated interview data were analysed and presented in themes.FindingsFindings show that there is an absence of a framework to promote GCB in Nigeria. Hence, GCB is low across the states. Twelve main sub-themes emerged as the barriers to GCB in Nigeria. Also, eight key sub-themes emerged as the possible concepts that can be used to improve GCB in Nigeria and formulated into a proposed framework to promote GCB in Nigeria.Research limitations/implicationsThis paper is limited to GCB in Nigeria and only 18 participants were engaged. Thus, this paper suggests that a mixed-methods approach should be conducted in future studies with wider coverage. This may assist to validate the paper’s findings.Practical implicationsFindings from this paper will stir up practitioners in green building and influence the promotion of GCB in the sector. As part of this study’s implications, suggestions through the paper’s proposed framework will benefit Nigeria’s policymakers to make decisions towards achieving GCB. This can be achieved via the proposed framework to promote the concept across Nigeria.Originality/valueThis paper is probably the first that attempted to investigate the barriers and proffer policy solutions via a framework to promote GCB in Nigeria and by extension in other developing countries.

Descriptive Approach

Construction industry has been proven to cause environmental problems ranging from excessive consumption of natural resources in construction, to the pollution of the environment. Studies on green building to minimize environmental impact are already underway. Tools of assessment of environmental performance of buildings are plenty. However, Middle East countries together with Gulf region are still away from practicing the concept of mitigating the impacts of buildings on the environment. Reasons could be relying on the insufficient awareness of building stakeholders, or the privilege of much fortune. The main objectives of this paper are to arouse the people's attention to the importance of assessment of environmental performance of buildings in KSA, and to introduce a sustainability model for project appraisal based on a multi-dimensional approach, that will be used for the assessment of a case study in KSA. The approach is using the LEED (Leadership in Energy and Environmental Design) rating system as a guide for the assessment. The plan of work includes reviewing the literature on the assessment of sustainability performance of buildings, displaying the LEED system, and assessment of a commercial building in Dammam. The paper uses the descriptive approach to study the problem and collect the data, and the comparative approach to compare the obtained data with the required standards of LEED. The case study, which is a commercial complex in Dammam, is one of these types of buildings widely spread in the development schemes of current real estate investment in KSA. While the building achieved some credits and prerequisites of LEED system, the building lacks many other points. The overall credits achieved are 22%, and the overall prerequisites achieved are 43%. The main problem of the building is related to energy and atmosphere aspects.

This study was conducted in response to the lack of green office buildings in Malaysia, despite the fact that the green concept has been initiated in Malaysia for many years. The Penang State Government has taken the initiative to establish the Penang Green Council (PGC) as the first state in Malaysia, and the implementation of green offices is one of its programme initiatives. Nonetheless, green offices are still in scarcity across Penang. This study identified the challenges faced in implementing green offices. Data were collected from five green building owners using semi-structured interviews and the data were analysed using thematic analysis. The outcomes revealed that the main challenges faced by green office adoption were lack of budget, lack of awareness, lack of expertise, ownership factor, and type of building. This study offers several implications for practitioners and policy makers to improve the adoption of green office in Malaysia. The results may be applied to raise awareness amongst practitioners and office owners regarding green practices in office buildings. The study outcomes may serve as reference to policy makers on enhancing the development of green buildings.
