Creating a sustainable future

As the world grapples with the challenges of climate change and resource depletion, the concept of an environmentally friendly built environment has gained significant importance. Designing and constructing spaces that minimise their ecological footprint is essential for creating a sustainable future. Buildingspecifier Editor Joe Bradbury explores what an entirely environmentally friendly built environment might look like, highlighting key principles and innovative solutions.

Energy Efficiency and Renewable Energy

An environmentally friendly built environment prioritises energy efficiency and the utilisation of renewable energy sources. Buildings are designed with high-performance insulation, energy-efficient appliances, and LED lighting systems. Passive design techniques, such as proper orientation and shading, maximise natural light and minimise the need for artificial lighting.

Renewable energy generation is integrated into the built environment. Buildings incorporate rooftop solar panels, wind turbines, and geothermal systems to harness clean energy. Excess energy can be stored in on-site battery systems or fed back into the grid, promoting sustainability and reducing reliance on fossil fuels.

Green Building Materials

Environmentally friendly buildings rely on sustainable, non-toxic building materials. Recycled materials (such as reclaimed wood and recycled steel) minimise resource extraction and reduce waste. Bio-based materials, like bamboo and cork, offer renewable alternatives to traditional materials.

Innovative construction materials, such as carbon-negative concrete and hempcrete, have a lower carbon footprint and sequester carbon dioxide during their life cycle. These materials contribute to carbon neutrality and reduce the environmental impact of the built environment.

Water Efficiency and Conservation

An environmentally friendly built environment emphasises water efficiency and conservation. Buildings incorporate low-flow fixtures, dual-flush toilets, and rainwater harvesting systems. Greywater recycling systems treat and reuse water from sinks, showers, and laundry, reducing reliance on freshwater sources.

Landscaping design includes native, drought-resistant plants that require minimal irrigation. Permeable surfaces, such as permeable pavement and green roofs, allow rainwater infiltration, reducing stormwater runoff and alleviating strain on drainage systems.

Smart and Connected Systems

Smart and connected systems play a vital role in an environmentally friendly built environment. Building automation systems monitor and control energy usage, optimizing heating, cooling, and lighting based on occupancy and external conditions. Advanced sensors and controls adjust systems in real-time, maximising energy efficiency.

Internet of Things (IoT) devices enable efficient resource management. Smart meters track energy and water consumption, providing real-time data for better decision-making. Connected transportation systems promote sustainable mobility, encouraging walking, cycling, and the use of electric vehicles.

Waste Reduction and Circular Economy

Minimising waste and embracing the principles of the circular economy are fundamental aspects of an environmentally friendly built environment. Buildings are designed for deconstruction and materials recovery, allowing for easy disassembly and reuse of components at the end of their life cycle.

Construction sites implement waste management plans, diverting waste from landfills through recycling and composting. Pre-fabrication and modular construction techniques reduce waste generation during construction and enable efficient resource utilisation.

Urban Planning and Green Spaces

An environmentally friendly built environment incorporates thoughtful urban planning and the integration of green spaces. Compact, walkable neighborhoods reduce the need for extensive transportation and promote a sense of community. Mixed-use developments facilitate access to amenities, reducing the need for car travel.

Green spaces, such as parks, urban forests, and rooftop gardens, improve air quality, mitigate urban heat island effects, and enhance biodiversity. These areas provide recreational spaces for residents and contribute to overall well-being.

Community Engagement and Education

Creating an environmentally friendly built environment requires community engagement and education. Residents are involved in the design process, ensuring that their needs and preferences are considered. Educational initiatives raise awareness about sustainable practices, encouraging residents to adopt eco-friendly habits.

Community gardens, composting programs, and shared resources promote a sense of ownership and encourage sustainable living. Collaboration between residents, local authorities, and building professionals fosters a culture of environmental stewardship.

Resilience and Climate Adaptation

An environmentally friendly built environment takes into account the challenges posed by climate change and focuses on resilience and adaptation. Buildings are designed to withstand extreme weather events, such as hurricanes, floods, and heatwaves. Robust construction methods, reinforced structures, and elevated foundations are employed to enhance resilience.

Integration of green infrastructure, such as bioswales and permeable surfaces, helps manage stormwater runoff during heavy rainfall events. Elevated or flood-resistant building designs mitigate flood risks in low-lying areas. Utilising natural ventilation and passive cooling strategies reduces reliance on energy-intensive cooling systems during heatwaves.

 

Additionally, the built environment embraces nature-based solutions to enhance climate resilience. Planting trees and creating green corridors can help mitigate urban heat island effects, improve air quality, and provide shade. Building and infrastructure designs incorporate climate data and future projections to ensure long-term adaptability.

By considering resilience and climate adaptation in the design and construction of the built environment, we can create spaces that are better equipped to withstand the impacts of climate change, protect communities, and promote sustainability.

What’s the alternative?

If we do not prioritise the construction of a sustainable built environment, several negative consequences could arise:

Increased Environmental Degradation: The construction industry is a significant contributor to environmental degradation. Without sustainable practices, we would continue to deplete finite resources, such as timber and minerals, at an unsustainable rate. The extraction and processing of these resources lead to deforestation, habitat destruction, and soil erosion. Additionally, the energy-intensive processes involved in traditional construction, such as concrete production, contribute to high levels of carbon emissions and air pollution.

Higher Energy Consumption and Carbon Emissions: Buildings account for a significant portion of global energy consumption and greenhouse gas emissions. Without energy-efficient designs and renewable energy integration, buildings would continue to rely heavily on fossil fuel-based energy sources. This would contribute to increased carbon emissions and exacerbate the effects of climate change. Rising energy demands would also put a strain on existing energy infrastructure and lead to increased costs for individuals and communities.

Vulnerability to Climate Change: Climate change is already impacting our planet, with more frequent and severe weather events. If the built environment is not designed to withstand these challenges, communities would become more vulnerable to flooding, heatwaves, storms, and other climate-related hazards. Lack of resilient infrastructure would result in increased property damage, displacement of residents, and disruption of essential services.

Waste Generation and Landfill Overload: Construction and demolition waste contribute to significant landfill volumes. Without sustainable practices, buildings would continue to generate substantial amounts of waste during construction, renovation, and demolition. This would not only strain waste management systems but also squander valuable resources that could be recycled or repurposed. Additionally, improper waste disposal can lead to soil and water pollution, further degrading the environment.

Adverse Health Impacts: Non-sustainable built environments can have adverse health effects on occupants. Poor indoor air quality due to inadequate ventilation, volatile organic compounds (VOCs) from construction materials, and exposure to toxins can lead to respiratory problems, allergies, and other health issues. Lack of natural light, improper noise insulation, and inadequate thermal comfort can also impact occupants’ well-being and productivity.

Social and Economic Inequity: Unsustainable built environments often perpetuate social and economic inequalities. Communities with limited access to sustainable housing and infrastructure face higher energy costs, decreased quality of life, and limited opportunities for social and economic advancement. Lack of affordable, energy-efficient housing options exacerbates housing crises and further marginalises vulnerable populations.

Missed Opportunities for Innovation and Economic Growth: Building a sustainable built environment provides opportunities for innovation, job creation, and economic growth. By embracing sustainable practices, the construction industry can drive the development and adoption of green technologies, creating new business opportunities and employment prospects. Failing to invest in sustainable construction means missing out on these economic benefits and falling behind in the global shift towards a greener economy.

Neglecting to build a sustainable built environment would lead to worsening environmental degradation, increased energy consumption and carbon emissions, heightened vulnerability to climate change, waste generation, adverse health impacts, social and economic inequity, and missed opportunities for innovation and economic growth. To mitigate these negative consequences, it is imperative that we prioritise sustainability in construction and design, adopting energy-efficient practices, renewable energy sources, and resilient infrastructure to create a better future for both the planet and its inhabitants.

In summary

Designing an entirely environmentally friendly built environment is a multifaceted endeavor that requires a comprehensive approach. By incorporating energy efficiency, renewable energy, green building materials, water efficiency, smart systems, waste reduction, thoughtful urban planning, community engagement, and resilience to climate change, we can create a built environment that minimises its ecological footprint and promotes a sustainable future.

From sustainable materials to smart technologies, from energy-efficient designs to community engagement, each aspect plays a crucial role in transforming our buildings and cities into sustainable, resilient, and liveable spaces. It is through innovative thinking, collaboration, and a commitment to sustainable practices that we can build a better future for ourselves and future generations.

By embracing the principles of environmental sustainability in the built environment, we not only reduce our impact on the planet but also create healthier, more comfortable spaces for people to live and thrive. Together, let us strive to design and construct an environmentally friendly built environment that supports our well-being while preserving the beauty and integrity of our natural world.

The planet experiences harsh temperatures, intense radiation, and a thin atmosphere that lacks the protection offered by Earth’s magnetic field. Construction techniques must account for these challenges, including the need for radiation shielding, temperature regulation, and durability against Mars’ atmospheric conditions.

Distance and communication: The vast distance between Earth and Mars introduces significant communication delays. This delay makes real-time remote control of construction equipment impossible, necessitating autonomous or semi-autonomous construction processes. Construction techniques must be able to operate with minimal human intervention and leverage advanced robotics and AI systems for efficient decision-making.

Limited resources: Unlike Earth, Mars has limited resources readily available for construction; traditional construction materials like wood and concrete are scarce, if not absent, on the Martian surface. Construction methods must adapt to utilize Martian resources such as regolith (Martian soil), ice deposits, and local minerals. In-situ resource utilization (ISRU) will be crucial to reduce reliance on Earth for construction materials and minimize the cost and logistics of transporting supplies.

Strategies for construction on Mars

Pre-fabrication and robotics: Given the challenges of the Martian environment and the limitations of human presence, pre-fabrication and robotic construction techniques will play a crucial role. On Earth, pre-fabrication involves constructing components off-site and assembling them at the final location. Similarly, on Mars, pre-fabricated modules could be transported from Earth or manufactured using local resources, reducing the complexity and cost of on-site construction. Robotics and autonomous systems will be instrumental in assembling and integrating these pre-fabricated components efficiently.

3D Printing: Additive manufacturing, or 3D printing, holds immense promise for Martian construction. Using regolith as a raw material, 3D printers can create structures layer by layer, eliminating the need to transport bulky construction materials from Earth. The European Space Agency’s MELT project and NASA’s Mars Ice House concept are examples of utilizing 3D printing technology to construct habitable structures on Mars. 3D printing offers the advantage of flexibility, enabling the construction of customized designs and adapting to the specific needs of Mars’ environment.

In-Situ Resource Utilization (ISRU): Leveraging the resources available on Mars through ISRU will be crucial for sustainable construction. Martian regolith can be processed to extract minerals and use them as building materials. Ice deposits found in the Martian poles can be harvested and utilized for water supply, life support systems, and as a raw material for manufacturing construction materials. ISRU will minimize the need for transporting materials from Earth, reducing costs and increasing self-sufficiency.

Habitat Design: Martian habitats must be designed to provide a safe and comfortable environment for humans. They need to withstand the harsh Martian conditions while supporting the physical and psychological well-being of the inhabitants. Design considerations include radiation shielding, thermal insulation, airtight seals, and the integration of life support systems. Habitats may employ underground or partially buried structures to provide additional protection from radiation and temperature extremes. Innovative architectural designs, such as inflatable structures or modular expandable habitats, can maximize habitable space while minimizing launch mass.

Potential benefits and impacts

Human expansion and exploration: Construction on Mars will be a significant milestone in human space exploration. Establishing habitable structures will allow for longer-duration missions, enabling astronauts to conduct in-depth scientific research and explore the planet’s surface more extensively. It sets the stage for eventual human colonization and opens doors to further space exploration, potentially paving the way for future missions to other celestial bodies.

Technological advancements: The challenges of Martian construction will drive technological advancements with practical applications on Earth. The development of autonomous robots, 3D printing technologies, advanced materials, and resource utilization techniques will have broader implications for terrestrial industries such as construction, mining, and robotics. The knowledge and experience gained from Mars construction projects will contribute to innovation and push the boundaries of engineering and space exploration.

The long and winding journey of HS2, still without end

,

Despite having very little public support, HS2 continues to tear its way through our countryside and villages, destroying countless habitats and displacing people from their homes. Those in favour estimate it to create 22,000 jobs over the next few years, while opponents claim it will destroy almost that many jobs. Is the rationale for what has eventually been labelled “a vanity endeavour” still applicable in a post-Covid world? Buildingspecifier.com’s Joe Bradbury discusses:

High Speed 2 (HS2) is currently being funded unwillingly by taxpayers throughout the United Kingdom. The proposals for it were made public in 2010, near the end of the previous Labour administration, and the first phase is scheduled to open in 2026. Yet, it is both over budget and behind schedule. Toxic mix… Nevertheless, opposition to the project is growing, owing to its poor economic case, negative environmental consequences, and better suggestions as to how to spend the money set up for HS2.

A study conducted by the ITV Tonight programme back in 2016 discovered that:

  • Only 15% felt that HS2 is worth £56bn
  • 58% didn’t think it’s a price worth paying
  • 77% of people would prefer that the money was spent in other areas, like the NHS
  • Nearly three-quarters of people thought HS2 would lead to price rises for train tickets
  • 60% said they would not pay more to ride on HS2
  • Only 7% would be prepared to pay increased prices for the high speed line
  • 80% said they felt sympathy for people who may lose their homes to HS2, even though they may be compensated
  • A mere 11% of people thought the high speed rail link would actually benefit the majority of commuters

 

That was 7 years ago. Since then, it has even harder to build a case for HS2.

For many years, politicians insisted that HS2 was on time and within budget. Skeptics referred to the Elizabeth Line (previously Crossrail), which appeared to be “on time and on budget” until a few months before it was scheduled to begin. This all changed in a matter of months, with billions added to the Crossrail budget. Worse, the launch date was pushed out from December 2018 to possibly 2021 in the summer of 2018.

Now, according to the HS2 website, Phase One will open sometime between 2029 and 2033… so place your bets!

Spiralling costs

Transport Secretary Grant Shapps published the Stocktake document by incoming HS2 Ltd Chair Allen Cook at the start of the Parliamentary term. This confirmed what opponents Stop HS2 had long predicted: HS2’s expenses and schedule were woefully behind schedule.

Parliament had been told by ministers that the budget for HS2 was £55bn. However the cost for HS2 officially went from £55bn in 2015 prices to £81-£88bn in 2019 prices (£72-78bn in 2015 prices).

When a new high speed railway was first presented as an alternative to expanding Heathrow airport, the suggestions were that this would cost about £18billion. However when the HS2 proposal was firmed up and made public, Phases 1 and 2 were expected to cost £33billion in total, with Phase 1 opening in 2026 and Phase 2 in 2033. By 2013, this had risen to £42 billion, excluding the cost of the trains. A further review set the funding envelope for delivery of the full HS2 scheme of £55.7bn at 2015 prices.

The overall cost of completing HS2 has now ballooned from £33bn a decade ago to an estimated £100bn in 2023. That’s almost double the original quote, and significantly more than the £18bn posited at its first suggestion.

Bad for the environment

Despite their best efforts to dress HS2 up as an ecologically sound project, the environmental case for HS2 fails to hold water; the operation of HS2 will cause increasing carbon emissions, well into the 22nd century, in addition to any embedded carbon from construction. There will be negligible modal shift from cars and planes, there will be massive damage to the natural environment, including sensitive wildlife sites and HS2 Ltd’s mitigation efforts are failing.

Even when HS2 was first suggested, the carbon case was at most neutral, with the operation of HS2 potentially balancing the carbon cost of construction over decades. Yet, things have deteriorated substantially since then.

Building HS2 will result in embedded carbon emissions, which HS2 Ltd predicted in 2019 to be roughly 1,451,000 tCO2e tonnes.

However, as of February 2019, the carbon case massively worsened, with the latest figures from HS2 Ltd showing that after 120 years of operations, HS2 would be increasing carbon emissions rather than reducing them.

Habitat destruction

HS2 Ltd has not given a comprehensive list of wildlife locations that will be directly or indirectly impacted by HS2, however it is known to number in the hundreds.

An examination by the Independent on Sunday way back in 2013 discovered that Phases 1 and 2 had already affected over 350 sites: they reported: “Among the sites that could be directly damaged or indirectly affected are a national nature reserve, 10 county wildlife trust reserves, about 50 ancient woods, 30 river corridors, 24 Sites of Special Scientific Interest (SSSIs, the highest level of protection) and hundreds of other wildlife habitats. Among the rare or scarce species at risk are the small blue butterfly, long-eared owl, stag beetle, great crested newt, purple hairstreak butterfly and Bechstein’s bat.”

More recently than the IoS report, the Wildlife Trusts condemned the HS2 Phase 2b draft Environmental Statement saying: “HS2 Ltd’s own figures for the latest phase of the Phase 2b route show it will have a devastating impact on important places for wild plants and animals. 12 highly protected areas for nature conservation known as Sites of Special Scientific Interest, 111 Local Wildlife Sites and 19 ancient woodlands will be seriously damaged.

“HS2 Ltd’s work on this latest phase of the HS2 route is derisory in its assessment of the environmental impact. It is incomplete, there isn’t enough detail, there are significant omissions, it lacks sufficient proposals to compensate for nature’s loss, and to make matters even worse, there’s very little information about the impact on species. On the evidence, we have been given, this phase will result in an unacceptable level of damage to wildlife along the route.”

The Independent also reported on effects from the operation of HS2, saying “The toll on individual animals will be great. A Spanish study found that high-speed trains kill about 36 animals per kilometre. If that was applied to both phases of HS2, this would result in some 20,000 mammals, reptiles and amphibians being killed on the line every year.”

Even their best efforts are a blunder

Even where HS2 Ltd has attempted to prevent animal loss, it has failed to do so. Here are a few examples:

  • Trees planted in 2018 to replace destroyed woods were allowed to die, according to HS2, because watering them was too expensive.
  • To build a “biodiversity zone,” HS2 Ltd destroyed an existing County Wildlife Park.
  • Berkshire, Buckinghamshire, and Oxfordshire Wildlife Trust (BBOWT) barred HS2 contractors from entering Calvert Jubilee Nature Reserve because HS2 planned to destroy wildlife habitat before replacing it, leaving wildlife with nowhere to go in the meanwhile. Luckily BBOWT were there…

In summary

I always try to keep an open mind, but it’s impossible to remain neutral on a topic as divisive as HS2. It appears that in 2023 (13 years after HS2 was conceived), it is significantly easier to argue against HS2 than for it. How alarming then, that this fact doesn’t seem to make a jot of difference to the outcome. We’re getting it… whether we like it or not.

…Are we truly that powerless? In spite of widespread objection from the British public and multiple members of parliament, the project ploughs ahead; through fields, pastures, homes, gardens, habitats and nature reserves. Will it all be worth it? Or are we tearing our country and its economy to shreds?
