The threat of global warming, together with international agreements like the Kyoto Protocol on sustainable/renewable development, has led to significant interest in the potential of using sustainable energy as a source of power in various buildings such as Solar Energy/Power and Biomass Heating/Bioenergy. This has resulted in rethinking in building construction supply chain industry. Amongst relevant declarations, the United Kingdom (UK) government made a commitment to ensure that 10% of energy production would be from renewable/sustainable sources by 2010 and would progressively increase to 15% by 2020 and beyond. This is a tremendous task and it is definitely affecting the building construction supply chain industry both locally and globally. A concerted effort is therefore required from academia, industry, the general public and the government to achieve these targets. However, Africa and UK cannot act alone to tackle the climatic issues that affect the building construction supply chain, and therefore, international collaborations are required especially with the foreign suppliers of building construction materials. Thus, designing and constructing Near Zero Energy Buildings (NZEB) embedded with ‘SMART’ Structural Health Monitoring (SHM) technology are not only important but necessary. A building which produces or emits energy through sustainable routes as much as it uses from the Grid is known as Near Zero Energy Buildings while Structural Health Monitoring technology is a way of monitoring and evaluating structural health using smart sensors.
Near Zero Energy Buildings (NZEB) project analyses current design practices especially for high integrity and safety critical structures made from composite materials such as building roofing and column. The capabilities of Structural Health Monitoring (SHM) technologies to provide dependable and continuous structural diagnosis and prognosis will be investigated and aligned with structural design cases. The research will involve propose stage and test hypothesis for new structural design principles that preserve the damage tolerance and fail safe nature of current design but incorporating ‘smart’ SHM features as a design variable. New concepts will arise at the point where SHM and structural design converge. The novelty of this work gives excellent prospects for high profile publications and dissemination in conferences.
The work will comprise theoretical investigation of structural design processes especially with respect to building structures and composite materials. Experimental test cases incorporating SHM technologies will also be realised and demonstrated based on new approaches to design that realise advantages in terms of weight, complexity and performance. Furthermore, application ofTheory of Inventive Problem Solving (TRIZ) will be integrated into the project because of its benefits such as segmentation or segregation and extraction.
Net Zero Energy Buildings (NZEB) Concepts
The following NZEB concepts have been identified from the work of Pless, S., and Torcellini, P., 2010:
1. Connection of Grid
2. Switching of Fuel
3. Renewable/Sustainable Energy Credits
4. Options for Energy Supply and Demand
1. Connection of Grid
In concept, NZEB generates excess energy than it employs annually and discharges excess Sustainable Energy generation to the utility (such as district hot water system and electricity grid) to control the energy employed. A utility connection is permitted for energy balances for NZEB. Based on assumption, on-site generation excess can be sent to the grid to be wholly employed.
2. Switching of Fuel
The definition of NZEB enables renewable/sustainable electricity generation to offset different fossil/traditional energy employs. E.g. natural gas energy employ can be offset with excess wind energy or solar energy (i.e. photovoltaic-PV) transferred to the grid; the offset level is calculated by the energy employ accounting method.
3. Renewable/Sustainable Energy Credits
Various Sustainable/Renewable Energy projects are not fully sponsored via the marketing of renewable energy credits (RECs). Though this is a pertinent financial tool, once the RECs are sold and then bought by another person, the project cannot claim the advantages of the renewable energy generated on site for the usefulness of NZEB classification. RECs are not resold in other different utility purchase models.
4. Options for Energy Supply and Demand
Many supply angles of renewable energy production technologies are available for NZEB. Examples of renewable energy production technologies are solar energy (i.e. photovoltaic-PV), geothermal energy, wind, biofuels/bioenergy and hydroelectricity. Renewable energy demand angle and efficiency measures combine methods that save energy but are not commercialised. These cannot be included in the supply angle balance for achieving an NZEB. Examples of demand angle renewable energy and energy efficiency methods consist of day lighting, solar heating, domestic solar water heaters and solar ventilation air preheaters. Renewable energy guiding principles in NZEB are formulated to minimise the movements of energy from production route to final usage and generate maintenance in the residential and commercial buildings environments:
· Reduce the total environmental influence by recommending building designs that are energy-efficient, utilization of renewable energy, and minimising conversion, transportation and transmission losses.
· Renewable energy technology must be available over the life duration of the residential and commercial buildings.
· Must have high repeatable/consistency data potential for future NZEB.

How I Made Buhari President in 2015 – Amaechi

Former Rivers State Governor and ex-Minister of Transport, Rotimi Amaechi, has said that he, and not President Bola Tinubu, played the pivotal role in making late Muhammadu Buhari president in 2015.
In a Friday interview on Arise News’ Prime Time, Amaechi, who is now a presidential aspirant under the African Democratic Congress, addressed longstanding claims by Tinubu.
During his pre-2023 campaigning, Tinubu said Buhari would not have become president without him and that it was his turn to become one too.
But Amaechi explained that as a serving minister under Buhari, he could not publicly challenge Tinubu’s assertions to avoid risking his position.
“When we decided to form the APC, while I was a minister, (Tinubu) was claiming he made Buhari president and I couldn’t respond because I was a minister under President Buhari. That would have been suicidal because Buhari could fire you,” Amaechi said.
He continued, “So I couldn’t have said, ‘You are wrong.’ He didn’t make President Buhari president. Not only was I the DG of the campaign, but everybody will bear witness that I did all the battle.
“I led the Governors’ Forum, criss-crossed the country fighting here and there trying to get Nigerians to know that this is the time for change.”
Amaechi served as Director-General of Buhari’s 2015 and 2019 presidential campaigns.
He was a key figure in the 2013–2014 defection of PDP governors that helped form the APC alliance, which ultimately defeated President Goodluck Jonathan.
However, Tinubu was also instrumental in Buhari’s emergence, leading the merger of major opposition parties, including his Action Congress of Nigeria, to form the All Progressives Congress, which challenged and defeated the then-ruling PDP.
The remarks come amid Amaechi’s positioning for the 2027 presidential race as part of the growing opposition coalition under the ADC.
He has been vocal in recent months criticising the Tinubu administration over economic hardship.

In medicine, oxygen is the invisible molecule upon which all human life depends. Remove it, and the body shuts down almost instantly. The brain weakens, the heart struggles, and every organ begins to fail. As someone who studies how the human body works, I have always understood the centrality of oxygen to biological existence. But in recent years, watching Nigerian society evolve in the digital age, I have arrived at another conclusion: connectivity has become the oxygen of modern civilisation.
Without network connectivity today, businesses freeze, students lose access to learning, hospital records fall into jeopardy, POS transactions struggle, markets slow down, and families become disconnected. Digital access is no longer a luxury; it is the infrastructure upon which modern life breathes.
And in Nigeria, one network increasingly stands out as the supplier of that digital oxygen: GLO.
Across campuses, markets, offices, villages, and urban centres, millions of Nigerians now depend on the Glo network for the daily rhythm of their lives. For students, it powers e-learning, research databases, virtual classrooms, and academic collaboration. For traders and entrepreneurs, it sustains mobile banking, online transactions, advertising, and customer communication. For farmers in rural communities, it ensures communication with farmland workers. For doctors and healthcare professionals, it enables telemedicine and rapid information exchange. In many homes, Glo is the invisible bridge connecting families separated by distance.
This is why many Nigerians increasingly describe Glo not merely as a telecom company, but as a necessity.
What is even more fascinating is the growing public confidence in Glo’s reliability, something I have personally witnessed. I recently observed a man asking a shop attendant to call his boss. After placing the call once, the attendant calmly replied, “Sir, his phone is switched off.” The man insisted he should call repeatedly before concluding. The attendant smiled and responded, “Sir, I am using Glo network. If Glo says the phone is unavailable, then it is unavailable.” Everyone around laughed, but beneath the humour was a powerful reality: people increasingly trust the reliability and clarity of the Glo network. That brief moment was more than a casual conversation; it was a testimony to the confidence Glo has quietly built among Nigerians.
The reality becomes even clearer during moments of national stress. In an era defined by climate change, unstable electricity supply, flooding, extreme heat, and infrastructural disruption, telecommunications networks face enormous pressure. Floodwaters damage fibre optic cables. Heat weakens sensitive electronic systems. Power failures destabilise base stations. Yet despite these challenges, millions of Nigerians continue to experience remarkable connectivity stability on Glo.
That stability is not accidental. Globacom has continued to invest heavily in infrastructure upgrades and network improvement projects aimed at enhancing customer experience nationwide. For millions of Nigerians, clearer calls and faster internet are no longer wishes but daily realities because of the company’s sustained commitment to expanding and strengthening its network systems.
What makes Glo exceptional is not simply its coverage, but its resilience. The company has increasingly embraced hybrid energy solutions involving solar systems and battery storage technology to reduce dependence on diesel-powered infrastructure. This improves network reliability during grid failures while simultaneously reducing environmental pressure. Glo has also undertaken extensive fibre reconstruction and relocation projects across Nigeria, redesigning network routes to withstand environmental disruptions such as flooding, erosion, and climate-related damage. Its investments in expanded spectrum capacity and advanced technologies have further improved efficiency, enabling stronger data delivery and smoother connectivity for subscribers across the country.
From my vantage point in Kano, a region experiencing intense heat and significant environmental pressure, the importance of resilient connectivity cannot be overstated. For traders in Sabon Gari Market, network access means economic survival. For students at Bayero University, it means uninterrupted learning and research. For countless young Nigerians trying to build digital businesses, it means opportunity itself.
In many respects, Glo functions like the respiratory system of Nigeria’s digital society. The Glo-1 submarine cable and Glo fibre optics act like lungs, bringing global bandwidth into the country. The national fibre network resembles blood vessels distributing connectivity nationwide. The 4G LTE base stations function like capillaries, delivering data directly to the individual user whether in Kano or far beyond.
The subscriber shouting “Glo Unlimited!” during a blackout while data continues flowing is not merely celebrating affordable internet. They are experiencing the result of years of investment, resilience engineering, and technological foresight.
Calling Glo “The Digital Oxygen” of Nigeria is therefore not poetic exaggeration, it is an acknowledgment of reality. In a country where millions now live, learn, trade, communicate, and dream through digital connectivity, Glo has become more than a network provider. It has become the vital breath upon which modern Nigerian life increasingly depends…
