African plumes bring heat of the Sahara to UK – but climate change could make them less frequent

It’s not often that the UK feels as hot as the central Sahara, but there were certainly a few days in the summer of 2022 when that was the case. Such heat waves can occur when the Sahara arrives on our doorstep on the back of unusual winds. How do these events work and what can we expect from them in the future?

Heat waves are made in several ways, starting with intense sunshine. But as the early weeks of the summer of 2023 in the UK have shown, you can have noticeably cool air and bright, near-peak summer sunshine at the same time.

What really raises the temperature is the importing of heat from somewhere else. That process is often very efficiently carried out by the wind and that somewhere is the Sahara, when a southerly wind blows for long enough. We have come to call these events African plumes, or sometimes Iberian plumes as you may have heard them described in recent weather forecasts. They only visit the UK a few times a year.

Where plumes come from

African plumes are characterised by a hazy atmosphere laden with dust from the Sahara – the biggest source of that material anywhere on the planet come the summer months in the northern hemisphere.

Very large particles of dust are raised from the desert surface by gusts blowing over hundreds of kilometres, produced by the outflow of energy from thunderstorms. The big bonus following the arrival of this air in the UK is very colourful sunsets, as the setting rays are scattered by the dust, leaving only the red colours of the more elusive longer wavelengths of light for us to see.

While the process of importing heat from afar might sound exotic, it isn’t really. That is exactly what the weather is geared to do. Every day the Earth’s atmosphere has to respond to a never-ending problem of being inundated by an unfathomable amount of energy from the sun and to make things interesting, that energy is unevenly distributed so that some regions, such as the tropics and subtropics receive lots and other regions, notably the high latitudes and polar regions, very little.

Outside the tropics, the number one method for sorting out that discrepancy in energy is to move heat in the winds. In the northern hemisphere, winds from the south are warm and those from the north cool. A constant supply of cool northerly wind has been a key reason why decent June sunshine hasn’t raised temperatures just yet this summer. By crossing latitudes, cool winds going south and warm winds going north help to even up the problem of uneven heating from the sun.

At the latitudes of the UK, weather systems transport more than 3 petawatts of heat polewards. That is about 300 times the installed electricity generation capacity worldwide. If the climate system is so good at carrying out this heat transport, what is it that makes the African plume events infrequent?

First, to line up a wind which blows all the way from the Sahara to the UK takes a special configuration of pressure systems. No one low or high pressure system is quite big enough to do this on its own. And second, that configuration has to stay in place for at least three days because the wind has to travel the better part of 3,000 km.

Assuming those things are to hand, the UK can experience Sahara-like conditions. Of course, the temperature of the wind will be modified as it makes its journey, in this case, cooling slightly the further it gets from the furnace of the Sahara. But that cooling process is much less efficient than you might think. Air retains the conditions at its origin quite stubbornly, and crossing the hot Iberian Peninsula as African plumes have often done in the past – a part of the world which is warming steeply as a result of climate change – doesn’t help.

What the future has in store

Will warming in the UK in future decades result in more African plumes? Well, here’s the surprise. Meticulous work by the Met Office which involved slicing up British weather into 30 different types showed that three out of four of the patterns which can generate southerly winds from the overheated Sahara are actually projected to become less frequent in future, and only one (a southerly wind driven by a high pressure system over Scandinavia) is expected to increase.

Likewise, the persistence or longevity of those weather patterns (and remember, to get the Saharan heat to the UK requires it persisting for three days or more) decreases for three out of four patterns, again only increasing in the case of the Scandinavian high. Meanwhile, there are also weather patterns which can transport heat from central Europe to the UK. And the Met Office work shows that these patterns are set to increase in frequency in the future – and also extend into the autumn months.

Dry soils over Europe reinforce the heat-making pressure pattern. Sunshine warms a dry surface much more readily than a wet one. So Europe is a source of intense heat for Britain too, with temperatures not far off those of the Sahara.

This plume of heat forecast for early June is a good example. We might lose those striking sunsets made of Saharan dust, but the heat is here to stay.

We must move to a circular economy – here’s how

We must move to a circular economy – here’s how

Building activity produces 18% of emissions and a shocking 40% of our landfill waste. We must move to a circular economy – here’s how

By M. Reza Hosseini, Deakin University and Tuba Kocaturk, Deakin University

Architecture, engineering and construction employ 1.2 million people in Australia and account for 9% of GDP. But our biggest services sector also produces roughly 40% of landfill waste and accounts for 18.1% of Australia’s carbon footprint. The sector must change its practices fast for Australia to meet its commitments to cut emissions under the Paris Agreement.

A circular economic model can help solve the environmental challenges created by our built environment – water, waste and power systems, transport infrastructure and the buildings we live and work in. A circular economy involves sharing, leasing, reusing, repairing, refurbishing and recycling materials and products for as long as possible.

Circular economy principles have gained recognition from all levels of government in Australia. But there’s a big gap between acknowledgement and action. Progress towards systemic change has been very limited.

A new report by university and industry experts lays out a roadmap to a circular economy. Those working in the sector reported the top three barriers as: a lack of incentives, a lack of specific regulations, and a lack of knowledge. The top three enablers were: research and development of enabling technologies, education of stakeholders, and evidence of the circular economy’s added value.

The huge amount of waste created by building construction and demolition makes the industry unsustainable.

So what are the world leaders doing?

Extensive research for the report drew on real-world experiences, including a survey and interviews with stakeholders. The report offers practical recommendations to drive the transformation to a circular economy, with examples from global front-runners.

The first recommendation is to learn from these nations. Most are in Europe.

A leading example is the Netherlands’ “Cirkelstad”. This national platform connects key players in the transition to a circular economy in major cities. It provides a database of exemplary projects, research and policies, as well as training and advice.

Cirkelstad highlights the importance of broad collaboration, including research organisations. One outcome is the City Deal initiative. It has brought together more than 100 stakeholders with the shared goal of making circular construction the norm. They include government bodies, contractors, housing associations, clients, networks, interest groups and knowledge institutions.

We rarely see such collaboration in Australia. Connections between government, research and industry practices have been weak. Our universities compete fiercely.

In Denmark and Sweden, rigorous regulations have been effective in promoting circular practices. Denmark has incentives for the use of secondary materials such as recycled brick. It also promotes designs that make buildings easy to disassemble.

In Sweden, contractors must give priority to using secondary materials in public projects. Suppliers are evaluated based on their environmental impacts

In Canada, Toronto is notable for its proactive approach. Measures include a cap on upfront carbon emissions for all new city-owned buildings.

Test beds and pilot projects have proven effective, too. A good example is the UK’s Waste House.

Waste House was built using more than 85% waste material from households and construction sites. Yet it’s a top-rated low-energy building. The project is an inspiration for architects and builders to challenge conventional construction methods and embrace circular practices.

Much of the focus of Finland’s circular economy initiatives is on construction and urban planning. Various policy tools and incentives encourage the use of recycled or renewable materials in construction. The renovation of Laakso hospital in Helsinki is a notable example.

Strategic zoning of public spaces can also be used to bolster circular economy activities. An example is the repurposing of urban land for activities such as waste sorting.

The Brighton Waste House was made largely from recycled materials.

How can Australia create a circular economy?

Australia has been slow to adopt such measures. There are voluntary schemes, such as Green Star, that include emission caps for buildings. However, Australia lacks specific, well-defined requirements to adopt circular economy practices across the built environment sector.

Our report’s recommendations include:

  • develop metrics and targets to promote resource efficiency
  • adopt measurable circular procurement practices for public projects
  • provide incentives for circular practices
  • establish technical codes and standards that foster the use of secondary products.

The report finds funding for collaborative projects is badly needed too. Regrettably, the Australian built environment is not seen as a research funding priority. But more funding is essential to foster the innovation needed to make the transition to a circular economy.

Innovation can help us reconcile the public demand for spacious homes with sustainable construction practices. We can achieve this through a mix of strategies:

  • moving towards modular construction techniques
  • creating incentives to adopt circular design principles
  • making adaptive reuse of existing structures a priority
  • designing multi-functional spaces that makes the most of resources.

Integrating circular economy principles into education and training at universities and schools can embed a culture of innovation. Equipping students with this knowledge and skills will enable the next generation to drive change in our built environment.

Currently, there are few Australian-based training programs that focus on the circular economy. And available courses and programs overseas are costly.

There is also a need to promote inclusivity in the built environment sector. Circular solutions must incorporate cultural considerations.

By embracing the above strategies, Australia can foster a harmonious balance between cultural values, environmental sustainability and efficient resource use.

Collectively, these initiatives will lay the foundation for a circular economy in the built environment sector. The growing need for housing and infrastructure underscores the urgency of achieving this goal in Australia. Ultimately, consumers, industry and the environment will all benefit.

Building nature positive into the energy transition

Building nature positive into the energy transition

Advertisements
Published by wbcsd on 2 June 2023 and written by: Pete Jones, Manager, Nature, Diana Ferrari, Manager, Energy & Mariana Heinrich, Director, Energy, this following insightful view of our world of today appears to be a soft-spoken description of the diverse but global and uniform maltreatment of our mother nature.
.

Nature is the backbone of the world economy. Industries from agriculture to energy impact and depend on the natural world to thrive. Global populations and economies continue to grow, as do their demands on nature and natural resources. Future resilience and prosperity demand that these needs are managed sustainably.

Wildlife populations have decreased by 70% in the last 50 years,1 which puts multiple ecosystems at risk of collapse. The energy sector accounts for 10% of the pressures causing biodiversity loss,2 with oil & gas and utilities having a particularly high impact, largely due to pollution, greenhouse gas emissions and impacts on species and their habitats. Even renewable electricity technologies can have unintended effects on nature. For example, the total amount of land and sea area required to generate the world’s renewable energy requirements is circa 1 million km2, equivalent to almost twice the size of France.2 Any development close to this figure will result in the loss of natural habitats and undermine nature’s resilience to climate change effects. Therefore, we need a holistic framework as part of the global energy transition to address these impacts and, simultaneously, realize opportunities for nature restoration.

The good news is that in December 2022, the Kunming-Montreal Global Biodiversity Framework was adopted, providing the ambitious global aim of halting and reversing biodiversity loss by 2030. While delivering the targets set out in the Global Biodiversity Framework will be a shared task between governments, businesses, financial institutions and civil society, we need more investment, particularly from the private sector, to scale up efforts. This insights piece describes what businesses can do now to take action as required by the Global Biodiversity Framework.

At WBCSD, we are helping companies navigate and manage their nature-positive journeys by providing guidance for consistent and credible business actions, including for specific value chains. Our Roadmaps to Nature Positive are mapping the key nature impacts and dependencies and are identifying priority actions across three high-impact global value chains: land-based (Food & Agriculture and Forest), built environment, as well as energy. This is aligned with broader efforts to map sector transitions to nature-positive in collaboration with Business for Nature and the World Economic Forum.

Our team will lead a workshop at the Reuters Global Energy Transitionin New York on 7 and 8 June. Learn more about what we will cover at the bottom of this blog!

Nature Positive Roadmap for the Energy System

The Nature Positive Roadmap for the Energy System will provide tools and guidance for companies to implement nature-positive transition plans using the globally agreed high-level actions for nature: ACT-D, i.e., Assess, Commit, Transform and Disclose. In addition, it will support companies in setting science-based targets for nature (in line with the Science Based Target Network (SBTN)) and applying the Taskforce for Nature-Related Financial Disclosures (TNFD) framework to nature disclosures.

Emerging insights so far include that:

  • The energy system will play a key role in contributing to the Global Goal for Nature: it has broad and significant impacts on nature, including water use, air pollution and emissions, land intake, habitat fragmentation and disturbances during construction and operation. But it also has massive potential to drive nature-positive change within its value chain and beyond as an essential component of the supply chains of almost all public and private entities, as well as final customers.
  • It is key to consider trade-offs between impacts on nature, climate and people: especially in the energy system, climate impacts have been at the forefront of company actions so far, but the increasing momentum around nature offers an opportunity to rebalance and consider the overall implications for all three topics.
  • We need deep collaboration along the entire value chain to be able to implement impactful transformative actions at a global scale. To enable this collaboration, transparency is required on KPIs, baselines, disclosure and targets so that these can be embedded into each step of the value chain. New metrics are needed for that, and developing and testing these new metrics will take time, as will building partnerships within the value chain that catalyze nature-positive innovation.

TNFD pilot project with WBCSD members

Alongside the roadmap development, six WBCSD member companies have been involved in our TNFD energy system pilot, testing its draft version and providing feedback to the TNFD as well as on the Nature Positive Roadmap.

Key findings to date:

  • The piloting companies already have policies and processes in place to manage and monitor impacts, risks and opportunities associated with nature. Most of them focus on addressing their own impacts, e.g., through converting habitat, using water or via emissions. Some pilot companies are already applying concepts such as “net-positive impact” or “net gain” to individual projects, particularly for biodiversity.
  • To capture the wider nature-positive agenda beyond biodiversity, pilot companies are now undertaking gap analyses between their existing commitments, practices and management tools and what working toward nature-positive requires. Such analysis is necessary to integrate nature-positive aligned approaches more explicitly into strategic business planning and management processes, as well as identify any capacity/skills needed to implement them.
  • New for many companies is the need for a deeper focus on nature impacts and dependencies arising in upstream activities and, for some companies, in their products sold downstream. One possible approach explored during the pilot is to do an initial, qualitative assessment to prioritize those business units for a more detailed assessment.

What’s next?

The overall work on the Roadmap for the Energy System will continue through 2023 and most of 2024, releasing outputs for companies to use along the way – the first ones in Q3 2023.  WBCSD is also setting up an SBTN Preparer Group and scoping a TNFD Preparer Forum. These will help companies to get ready to set science-based targets for nature and TNFD-aligned disclosures.

Join us at the Reuters Global Energy Transition Conference for a deep dive into energy and biodiversity

Our team will be leading a workshop at the Reuters Global Energy Transition 2023As one of Reuters’ flagship events, the conference will gather 750+ executives in New York on 7-8 June to shape and deliver the energy systems of the future. At our workshop, the attendees and us will share advice on how to accelerate nature-positive action via three focused break-out groups:

  • How to apply the 2022 Global Biodiversity Framework (GBF) to your business – what targets and metrics are needed?
  • How to implement the TNFD to help your business – how to integrate biodiversity into enterprise strategy and risk management processes?
  • How to take Nature Positive action on the ground – what actions are other companies already taking to reverse impacts and restore biodiversity?

The purpose of the workshop will be to provide attendees with ideas and examples of approaches already used, or proposed, to address the questions above. Attendees will leave the workshop better equipped to drive nature action within their businesses.

Mariana Heinrich (WBCSD Director, Energy Pathway), Pete Jones (WBCSD Manager, Nature and secondee from ERM) and Margaret O’Gorman (President, Wildlife Habitat Council) will run the workshop. We hope to see you there! Register here to attend.

Top 5 ways to slash carbon emissions in the construction industry

Top 5 ways to slash carbon emissions in the construction industry

As public concerns are mounting, governments are taking action, bringing in environmental targets designed to thwart runaway global warming, for the Certainty of hitting new temperature highs is nowadays unquestionable.

Globally, the sector contributes around 23% of air pollution, 40% of drinking water pollution, and 50% of all landfill wastes.

Meanwhile, the built environment as a whole is responsible for 30% of total global final energy consumption and 27% of total energy sector emissions, according to the IEA.

Populations around the world are already grappling with the impacts of climate crisis and environmental breakdown, from melting permafrosts and ice in the polar regions, to increases in extreme weather across the globe, creating greater risks of wildfires, floods and droughts while rising sea levels and worsening storms threaten coastal communities.

As public concerns are mounting, governments are taking action – bringing in environmental targets designed to thwart runaway global warming and help turn the tide on ecological destruction.

To stay ahead of the forces driving global business, construction firms must re-evaluate the pivotal role in how our species interacts with the planet.

Five key ways they can do this include:

1. Not building

Instead of resource-intensive new-builds, retrofitting existing building stock must play a much bigger role.

Last year the International Energy Agency called for 20 per cent of all existing building stock to be retrofitted by the year 2030 in order for the world to meet its climate targets, and said it should be a “key” focus of the construction industry’s decarbonisation efforts.

The organisation has called for an annual “deep renovation rate” of over 2% from now to 2030 and beyond.

2. Planning for long-term environmental gains

If new building works must go ahead they should start with a wholesale consideration of their form, function and impact on society, and how these impacts can be mitigated. This starts with planning.

Urban planners can make the built environment more environmentally friendly by adopting eco-friendly design approaches at an early stage.

This includes minimising land use, prioritising connections to public transport networks and walking and cycling routes to discourage private car use, and increasing access to green and blue spaces such as parks and bodies of water, which can enhance air quality, protect some natural resources and boost the health and well-being of the people in the environment.

Furthermore, the importance of implementing high Environmental Social Governance (ESG) standards within the industry is growing rapidly. As pressure for the construction industry to clean up its act grows, so too is the requirement for ESG standards, which should one day become a compulsory and universal system for evaluating the sustainability of both new developments and retrofitted buildings.

3.  Incorporating passive design and renewable energy

Passive design features combined with renewable energy can dramatically lower the carbon footprint of a completed building when it is in use.

This starts with selecting suitable building locations and orientations to make the best possible use of the natural environmental conditions.

Then, layout of rooms, window design, insulation, thermal mass, rain collection, shade and ventilation, all play significant roles in making a building as efficient as possible.

Passive House–certified homes use an estimated 80% less energy for heating and cooling than conventional buildings.

With the addition of solar panels or wind turbines for power generation and water heating, energy demands – and therefore environmental impacts – can be even lower. A new generation of photovoltaic solar-tiles promise even greater levels of flexibility and enhanced returns on investment.

Meanwhile, geothermal heat pumps and air-source heat pumps have enormous levels of efficiency in comparison to traditional gas boilers.

4. Cementing a concrete lead

Concrete is the most widely used man-made material in existence and is second only to water as the most-consumed resource on the planet.

Described as “the most destructive material on earth”, the production of cement, which is used to make concrete, is responsible for up to 8% of global CO2 emissions and would be the third largest carbon dioxide emitter in the world if listed as a country in its own right, causing up to 2.8bn tonnes of CO2 a year, surpassed only by China and the US.

Reduction in cement use is vital. This can be done by using recycled materials in the mix, reducing the amount of cement used, and using alternative materials such as fly ash or slag.

5. Choosing sustainable building materials

As well as reducing usage of concrete or mixing less damaging kinds of concrete, there are also various alternatives to concrete which take a much lower environmental toll on the planet. These include hempcrete, which is made from hemp plants mixed with a lime-based binder. This forms a lightweight, breathable construction material with excellent insulation properties.

Another alternative is rammed earth, which is made by compressing soil into a formwork. It is durable, low-maintenance, and has excellent thermal mass properties.

Other exciting modern breakthroughs in construction materials include straw bale construction, cross-laminated timber (CLT), and bamboo, all of which can often be produced with low impacts to the environment, and match existing construction materials for strength and practicality.

Conclusion

For companies to thrive and survive, embracing the health of our planet is a must. With the Cop28 summit in Dubai on the horizon, and the hosts warning that the IPCC has already “made it crystal clear that we are way off track”, the importance of adopting ambitious targets to achieve sustainable building has never been greater.

How Do International Codes Assure Sustainability?

We Expect A Lot From Our Buildings — How Do International Codes Assure Sustainability?

.

Today, society faces 3 major challenges in the built environment: ensuring building safety, improving sustainability, and addressing our affordable housing crisis.

May is Building Safety Month. Up-to-date international codes can make communities more equipped to endure increasingly frequent and severe weather events, improve sustainability, and address the affordable housing crisis. This year, innovation and collaboration are evolving due to the increasing frequency and severity of global weather events. All communities need building codes to protect their citizens from disasters like fires, weather-related events, and structural collapse.

It seemed to make sense to learn more about how modern and innovative international building codes address these imperatives, how code officials work day in and day out to keep the public safe, and how the International Code Council is enabling the flow of innovative policies and practices around the world to improve the built environment.

So we reached out to Dominic Sims, CEO of the International Code Council, who agreed to an interview.

Q: Thanks for making yourself available to answer some questions. For those unfamiliar with the International Code Council, why is it in existence, and what effect has it had on cities and towns across the globe?

Dominic Sims, CEO of the International Code Council, Photo provided by International Code Council

The International Code Council was established in 1994 as a non-profit organization dedicated to developing a single set of comprehensive and coordinated model building codes. The mission of the Code Council is to steward the development process for model codes that benefit public safety and support the industry’s need for one set of codes without regional limitations. We are a member-focused association with members from across building industries who come together to participate in our democratic and transparent process to develop the most widely used set of building safety codes and standards in the world – the International Codes® (I-Codes®).

Our technical staff works closely with legislators and code officials to help jurisdictions implement the most appropriate set of codes for their specific regions.

 

 

Q: I’m struck by the call for reciprocity toward improving sustainability and addressing the affordable housing crisis. These 2 objectives seem not to be related. Might you offer some insights into their symbiosis?

We expect a lot of our buildings. They are complex systems that have broad ranging impacts on our lives and communities. They protect us from hazards, influence our health, and impact our environment. Finding the balance across all these expectations while maintaining affordability is challenging, but the Code Council and governments must navigate these complexities.

Housing affordability is particularly important for low and moderate income households. These households are often the hardest hit by disasters — many of which are exacerbated by climate change — and lack the resources for post-disaster recovery. At the same time, they spend a disproportionate amount of their income on utility bills — in some places 3 times as much as the average household. When we talk about housing affordability, it’s not just whether we can get someone in a house but whether they can afford to stay there.

The International Code Council is currently the only code development organization that actively considers cost as an element of the code development process. Through the code development, process stakeholders from across the building industry come together to identify the best practices for safety and sustainability while ensuring the resulting buildings remain affordable and accessible to broad populations. Naturally, individual communities have their own perspectives on priorities for their building stock. The Code Council provides communities with tools to achieve those priorities from model codes that capture the current consensus to stretch codes that can assist communities in going beyond minimum-level requirements.

Q: May is Building Safety Month. What should our readers know about the need to adopt modern, regularly-updated building codes?

Today, society faces 3 major challenges in the built environment: ensuring building safety, improving sustainability, and addressing our affordable housing crisis. Modern and innovative international codes are society’s first line of defense to address these imperatives. One of the most cost-effective ways to safeguard communities against natural disasters is to build using hazard-resistant building codes.

FEMA studies show that every dollar invested in the adoption of modern building codes provides 11 times more in savings by reducing casualties, lowering the cost of building damage and helping communities get back on their feet faster by minimizing indirect costs such as business interruptions and lost income. We want to emphasize to all communities the importance of adopting modern building codes and stress the critical importance of continued inspection and enforcement to keep buildings and their occupants safe and healthy. We also encourage local governments to fund their building departments to support the needed level of maintenance inspections.

 

 

The formula for success in implementing and supporting modern building codes and inspections is simple: staff, train, and finance.

Q: How is the building industry working to increase water efficiency through innovative practices and technologies — not just domestically but worldwide?

Logo provided by ICC

Innovation and collaboration must evolve due to global weather events’ increasing frequency and severity. There are many examples of countries in water-scarce areas that are innovating to increase water efficiency. Those involved in the code development process can draw best practices from the following examples across the globe:

  • Israel is leading the world through its policies, practices, and technologies for its water resources and conservation, most notably through reclaiming over 80% of its wastewater and stormwater for agricultural operation.
  • Saudi Arabia boasts the highest production of desalinated water worldwide (the country removes salt out of the Red Sea and the Persian Gulf) and is in the process of converting its desalination plants to solar.
  • Cape Town, South Africa is incorporating automated domestic water metering installations to set a target water usage for each resident per day, leveraging alternative water sources, and updating their supply network infrastructure.
  •  The United Kingdom is cutting water use through water metering, incentives for water-saving technologies, hosepipe bans, and investing in updating the country’s water supply equipment.
  • The North China Plain has addressed increasing agricultural demands on water through increased monitoring, institutionalized water conservation practices, ground leveling, and more efficient drainage and irrigation sprinklers.

Q: How does Building Safety Month address some of the issues that we face as a global community, including extreme weather events and water scarcity?

Clean water is the world’s most precious commodity, and public health depends on safe and readily available water. The World Health Organization estimates over two billion people live in water-stressed countries, which is expected to worsen in some regions due to a changing climate and population growth. Water conservation and efficiency issues have become crucial conversations amongst building safety professionals in recent years. Building Safety Month raises awareness about these issues by reinforcing the need to adopt modern, regularly-updated building codes, and helps individuals, families, and businesses understand what it takes to create safe and sustainable structures.

 

 

Q: What additional details or insights might you provide on how we can institute these best practices in the US?

There is currently no national standard on maintenance and inspection. Individual states follow their own enforcement procedures to seek out, modify, adopt and enforce their own building codes and standards. Currently adopted codes, which local jurisdictions can, and do, modify on a case-by-case basis, may or may not include provisions for building re-inspections and maintenance requirements. The International Property Maintenance Code® (IPMC®) established minimum requirements for the maintenance of existing buildings through model code regulations that contain clear and specific maintenance and property improvement provisions. The latest edition is fully compatible with the International Building Code® (IBC®).

Every jurisdiction needs to understand what their specific regional needs are so that their building, maintenance, and re-inspections codes have appropriately specific provisions for the natural, environmental, and emergency conditions more prevalent in their area (e.g., Florida hurricanes, Kansas tornadoes, California earthquakes and wildfires).
