Shaping Tomorrow’s Buildings: Towards Carbon-Positive Architecture

Posted on by

We have been involved in exploring the new frontiers of low-energy and low-embodied carbon designs for many years. Today, I’m excited to share the crucial role architects, like us, have in fighting the biggest challenge of our age – the climate crisis.

Chapter 1: The Imperative of Carbon-Conscious Building

Constructing the buildings that define our skylines and streets generates a staggering 39% of global carbon emissions. These emissions include “embodied carbon” from the manufacture and transport of building materials, and the “operational energy” used in running the buildings. The goal, therefore, is to aim for “net zero emissions” – a balance between the carbon emissions produced and the carbon sequestered or offset by renewable energy sources. But to truly confront climate change, we must strive beyond neutrality towards carbon-positive buildings – structures that go a step further to remove more carbon from the atmosphere than they emit.

Chapter 2: The Carbon-Positive Paradigm

By producing more energy than they consume, carbon-positive homes raise the bar for sustainable living. They embody a compelling blend of benefits including economic gains, environmental improvements, and health advantages for their inhabitants. Achieving such architectural marvels involves careful choice of low embodied carbon materials and designing the building to create an energy surplus during operation.

Chapter 3: Demystifying Embodied Carbon

Creating carbon-positive structures starts with the selection of sustainable building materials. These materials reduce embodied carbon – the sum total of greenhouse gas emissions produced during their manufacture, transport, and installation. Remarkably, some building materials even sequester carbon, trapping it within the building for its lifespan. Materials like bamboo, cork, straw, hempcrete, cellulose fibre, and wool insulation, alongside timber sourced from sustainably managed forests. Prefabricated construction methods also play a crucial role in minimising waste, further reducing embodied carbon.

Chapter 4: The Power of Energy Efficiency

Nearly half of a home’s energy usage goes to heating and cooling. Implementing passive solar design – features that maximise natural heating and cooling – is therefore essential to reducing energy consumption. From building orientation and external shading to airtight envelopes, insulation, and energy-efficient windows, each element plays a part in reducing the need for mechanical heating and cooling. Green features such as green roofs and green walls, LED lighting, and passive heat transfer also contribute significantly to maintaining indoor comfort while reducing energy use.

Chapter 5: Harnessing Renewable Energy

Once a home’s energy consumption is optimised, it’s time to generate carbon-free power. Methods for doing this vary by location and include solar panels, wind turbines, and Ground Source Heat Pumps. It’s also worth noting that the grid itself is becoming greener. With ambitious targets for all electricity to come from 100% zero-carbon generation by 2035, the UK government is setting the stage for a more sustainable future.

Chapter 6: Certifications and Regulations to Ensure Sustainability

A plethora of building regulations and certifications exist to recognise sustainable and resilient design. Standards such as BREEAM Outstanding, the International Living Future Institute’s Zero Carbon Certification, and Powerhouse set benchmarks for sustainability. These rigorous certifications not only focus on operational energy usage but also consider energy inputs associated with construction and materials used.

Chapter 7: Beyond Regulations: Pioneering Carbon-Positive Architecture

Beyond meeting regulations, architects and developers around the world are pushing boundaries to design and build carbon-positive structures. ArchiBlox, an Australian-based architectural practice, has designed the first-ever carbon-positive prefab home, demonstrating that low-carbon design can be affordable, efficient and aesthetically pleasing. Similarly, the ZEB Pilot House in Norway shows how a small home can generate enough surplus energy to power an electric vehicle year-round.

Chapter 8: The Tah.Mah.Lah Project: A Living Example

Tah.Mah.Lah, a pioneering residential project in California, offers an early example of how homes can go beyond carbon neutrality. This environmentally regenerative home produces more energy than it consumes, restores native habitats, recycles water, and reduces waste. It serves as a beacon of inspiration, showing us how innovative design can lead to carbon-negative homes.

Chapter 9: A Future Vision: The Architecture of Tomorrow

Our focus on low energy and low embodied carbon designs reflects our commitment to the future of our planet. By harnessing sustainable materials, incorporating energy-efficient design principles, and using renewable energy, we can create homes that not only tread lightly on our Earth but actively contribute to healing it.

Chapter 10: Joining the Low-Carbon Revolution

The urgency of climate change requires us all to play a part in creating a sustainable future. As architects, we have the privilege and responsibility to lead the way in this low-carbon revolution. Whether you’re a homeowner looking to retrofit your existing property or a developer aiming to create the next carbon-positive building, we invite you to join us in this exciting journey towards sustainable living.

In conclusion, carbon-conscious building isn’t just a trend – it’s a necessary shift towards a sustainable future. Let’s build not just for our generation, but for those to come.

When designing ethical and environmentally friendly housing, it is essential to consider a building within the context of its environment. Beyond energy use, a zero-carbon home should facilitate a zero-carbon lifestyle, incorporating features like space for food production, bicycle storage, and home offices. Even in high-density areas, provisions can be made for green roofs, vertical gardens, and container growing. Blurring the boundaries between indoor and outdoor spaces through verandas and conservatories enhances the relationship between a sustainable home and its surroundings.

Chapter 10: Energy Use and Efficiency in Eco Homes

Beyond insulation and solar orientation, homeowners must actively reduce energy usage to create a truly sustainable home. Opting for A+++ rated appliances and highly efficient lighting, such as LED, can make a significant impact. Consideration should also be given to incorporating photovoltaics and other local energy generation methods to meet electricity requirements. By pre-heating water, active solar measures can further reduce energy loads. Addressing hot water heating systems and minimising associated heat losses are critical considerations in eco and Passivhaus design.

Chapter 11: Water Management for Sustainable Living

An often-overlooked aspect of green home design is the responsible use and management of water. Incorporating water-saving measures like low-flush plumbing and grey-water recycling can significantly reduce water consumption. Sustainable homes may also integrate composting toilets and alternative waste management systems to minimise environmental impact. Careful attention must be paid to the installation of water systems in Passivhaus projects to prevent heat loss. Additionally, waste management should prioritise on-site recycling, composting, and the use of reclaimed materials.

Crafting an Oasis within the Urban Jungle: The Art and Intricacies of Backlands Planning

Posted on by

Nestled within the confines of our contemporary urban sprawl lies an opportunity, often overlooked – the realm of the backlands plot. As an architect with two decades of experience leading a boutique, design-focused architecture studio, my journey has led me to deeply appreciate the charm and potential of backlands development. Our studio, passionate about pioneering sustainable and low embodied carbon designs, has been navigating the intricacies of backlands planning with a discerning and innovative eye, and I’m eager to share our insights and experiences with you.

Decoding the Backlands Puzzle

The backlands plot, a parcel of land situated at the rear or side of an existing property, can be an architectural gem in the making. Frequently a sizeable portion of a sprawling garden, these plots are often secluded from the bustling roads encapsulating them. The charm lies in their potential, large enough to cradle a new dwelling yet intrinsically private due to their positioning.

Historically, the practice of exploiting these plots was pejoratively referred to as ‘garden grabbing’, meeting opposition from local authorities. However, the lens through which we view these plots has transformed significantly in recent years. In our quest to fulfil housing needs in increasingly saturated environments, backlands development has emerged as a sensible and innovative strategy, enabling an escalation in housing density without expanding the urban footprint.

Such plots are a canvas for self-builders eager to create their dream abode on land they already own. However, treading the path of backlands planning isn’t without its hurdles. That said, a comprehensive application that anticipates and addresses pertinent concerns significantly heightens the odds of success.

Navigating the Labyrinth of Backlands Development

Embarking on a backlands project is akin to setting foot on a thrilling architectural expedition, punctuated by challenges to be surmounted. These hurdles revolve primarily around accessibility and the dynamics with neighbouring properties, though other considerations involving space, privacy, and design are of substantial significance.

A cardinal rule for a backlands plot to be planning-compliant is the availability of direct access to the road. This could be via a boundary fence, a discreet alleyway, or an access road. Ownership of the access pathway considerably simplifies matters when submitting the planning application.

Neighbourly relations can be a double-edged sword in backlands developments. Neighbours might view a new construction within their surroundings as intrusive, leading to potential opposition. However, objections can be mitigated if it can be convincingly demonstrated that the planning policies have been scrupulously followed, and that the development will not significantly impinge on the views or light entitlements of the neighbours.

Space and privacy are intertwined in the considerations that govern the success of backlands development. The proposed home must have sufficient space to breathe, avoiding a congested feel and aligning with the spacing pattern of the surrounding homes. Privacy is an integral part of this equation, with the plot location and proximity to neighbouring properties being critical elements.

Design, the backbone of our architectural vision, holds the key to successfully unlocking backlands plots. The constraints notwithstanding, creating a design that harmoniously balances your aspirations and the stipulations of the planning authorities can be a thrilling architectural challenge. The form and materials of the proposed structure may be dictated by the location, whether it involves adhering to a single-storey restriction to preserve view corridors or incorporating vernacular materials to harmonise with the local aesthetic.

Unlocking Success in Backlands Planning: A Guided Approach

Each planning authority has its own unique regulations and policies, making the expertise of an architect well-versed in backlands planning applications invaluable. Coupled with the insights of a planning consultant, their collective wisdom can pave the way for a successful application. While local area experience is beneficial, the core understanding needed is of backlands plots and their inherent constraints.

Here are some nuggets of wisdom for navigating backlands development:

  • Engage an experienced designer to guide your journey.
  • Keep your neighbours informed and involved from the outset to anticipate potential issues and defuse any brewing confrontations.
  • Undertake a planning pre-application to obtain expert advice and insights on potential challenges.
  • Strive to create a sustainable, future-proof home. The environmental advantages carry significant weight.
  • Demonstrate how the development will enhance the utilisation of the land.

Backlands Planning: A Case Study from North West London

One of our recent backlands planning applications and approvals involved an underused side garden situated close to a Conservation Area. Owing to the contentious nature of backlands plot applications, we embarked on a pre-application process to identify potential hurdles from the perspective of the local authority.

The pre-application advice is a fundamental part of the process, particularly for projects involving virgin sites or those seeking to establish key principles for site development before delving deep into the design process. This stage can be time-intensive but yields invaluable feedback from the local planning authority, providing clarity on the project’s viability and the likelihood of their support for your proposal.

This particular site already enjoyed road access, thanks to it being located at the side of a semi-detached plot enclosed by two roads. Additionally, the trees populating the pavement immediately adjacent to the site provided a natural screen, minimising visibility from neighbouring properties and ensuring no adverse impact on their views or light entitlements.

The Powerhouse Standard – Pioneering Eco Architecture

Posted on by

Throughout my career, my focus has been on creating low-energy and low-embodied carbon designs that contribute to a sustainable future. However, there is one project that stands out among the rest – the Powerhouse initiative.

The Powerhouse standard, hailed as the world’s toughest eco-building benchmark goes far beyond traditional sustainability goals. To meet this extraordinary standard, a building must not only produce more renewable energy over its lifetime than it consumes but also account for the energy used in its manufacturing, construction, operation, future renovation, and even its eventual demolition. In essence, a powerhouse must generate more renewable energy over a typical 60-year lifespan than it consumes throughout its entire life cycle.

But before embarking on the journey of calculating the renewable energy output of a powerhouse, it must first meet the passive house standard. This ensures that the building is meticulously designed to be as energy-efficient as possible, minimizing its energy demands from the outset. In addition to these requirements, a Powerhouse must also be sold or rented at market rates, provide a healthy indoor climate, and generate all its renewable energy on-site or in close proximity, even utilizing wave or tidal energy if feasible.

The Powerhouse project emerged as a collaborative effort between renowned international architecture firm Snøhetta, Swedish contractor Skanska, the environmental NGO Zero, and various other partners. It was a groundbreaking endeavour that sought to redefine what was possible in terms of sustainable architecture.

Kjørbo, nestled along Sandvika's enchanting seafront, graces Bærum municipality near Oslo, Norway. These two refurbished structures, dating back to 1980, span roughly 2,600 square meters each. Their collective energy consumption amounts to a staggering 250 kWh per square meter every year.

Their collective energy consumption amounts to a staggering 250 kWh per square meter every year. Architect: Snøhetta

Chapter 1: Powerhouse Kjørbo – Reimagining the Past for a Greener Future

In 2014, the world witnessed the completion of the first building to meet the Powerhouse standard – Powerhouse Kjørbo. Situated just outside Oslo, this project involved the deep retrofitting of two 1980s office buildings. The transformation was remarkable. The original glazed facade gave way to triple-glazing and insulated panels adorned with beautifully charred timber cladding. As a testament to our commitment to sustainability, we repurposed the existing windows for interior partitions, minimizing waste and exemplifying the principles of the circular economy.

During construction, we prioritized recycling and reusing materials, resulting in over 90% of construction waste finding new life in other projects. But the true highlight of Powerhouse Kjørbo lies atop its roof – a massive 1,500 square meter solar photovoltaic array that produces twice the energy needed by the building itself. This remarkable feat serves as a shining example of how sustainable design can transform existing structures into powerhouses of energy production.

Chapter 2: Drøbak Montessori – Where Nature and Education Harmoniously Coexist

Nestled amidst the lush forests and overlooking the majestic Oslofjord, Drøbak Montessori, a timber-framed school, exemplifies the essence of the Powerhouse standard. Designed to generate an estimated 30,500 kWh of solar power annually, the school seamlessly integrates cutting-edge technology with architectural elegance.

At the heart of the design lies an angular “solar plate” clad with south-facing PV panels, positioned at an optimal 33-degree slope to harness the sun’s energy. This unique feature also functions as a ventilation “stack,” facilitating the expulsion of stale air while simultaneously drawing in fresh air to supplement the building’s heat recovery ventilation system. The integration of sustainable technologies and the use of natural materials seamlessly blend the boundaries between the built environment and the natural world, fostering an environment that inspires wonder and respect for nature.

Mervi Flugsrud, a member of Drøbak Montessori, succinctly captures the spirit of the school, stating, “We believe that the building itself will contribute to increased understanding and respect for nature. We eagerly anticipate moving into the greenest school in Norway, where sustainability is not just a concept, but a way of life.”

Chapter 3: Powerhouse Telemark – Paving the Way for Future Sustainability

As the Powerhouse initiative continues to gather momentum, the next project poised to meet this extraordinary standard is Powerhouse Telemark – an office building in the idyllic Norwegian town of Porsgrunn. With completion scheduled for the coming year, Powerhouse Telemark serves as a testament to our unwavering commitment to sustainable architecture.

Drawing inspiration from nature, the building will feature a design that seamlessly integrates timber construction, minimizing its carbon footprint while simultaneously providing a warm and inviting atmosphere. It will rest on “weather-resistant wooden poles,” extending into the pristine waters of Holandsfjorden, further emphasizing the harmony between the built environment and the natural landscape.

Chapter 4: Svart – A Hotel Born from Nature’s Embrace

However, perhaps the true jewel in the Powerhouse crown is yet to come – Svart, an awe-inspiring hotel nestled at the foot of the Svartisen glacier in Norway’s Arctic region. Svart represents the culmination of our collective vision to create a circular building constructed primarily from timber, minimizing its impact on the environment while offering unparalleled comfort and luxury to its guests.

In preparation for this ambitious project, Snøhetta undertook an extensive study to map the behaviour of solar radiation in the fjord. The surrounding towering mountains and extended summer nights presented unique challenges, which we diligently overcame, ensuring that Svart’s solar PV systems would operate at optimal efficiency throughout the year.

As construction progresses, Svart is poised to become a beacon of sustainable hospitality, setting new standards for the industry and inspiring future generations of architects, designers, and travellers to embrace sustainable practices without compromising on luxury.

1. The Cornerstone: Energy Performance Certificates (EPCs)

EPCs, for those unfamiliar, play a pivotal role in the UK’s housing market. As a mandatory provision for rental properties, they offer potential tenants a window into a property’s energy efficiency. In simpler terms, a higher EPC rating can significantly increase the property’s allure to prospective tenants, acting as a beacon for those conscious of both their environmental impact and energy bills.

2. Navigating the New Building Regulations

The winds of change ushered in revamped Building Regulations on June 15th, 2022. Of these, landlords and developers must pay heed to:

  • Part L: Zeroing in on thermal performance.
  • Part F: Concentrating on ventilation.
  • Part O: A brand-new addition, highlighting overheating.

While these updated regulations predominantly focus on new constructions, existing properties undergoing major renovations aren’t exempt.

3. SAP’s Evolution: The New Assessment Methodology

The SAP assessment methodology’s technical upgrade is pivotal. Gone are the days when fossil fuel-based heating methods ruled the roost. The contemporary approach places energy-conserving building materials and non-fossil fuel heating methods on a pedestal.

4. The Changing Landscape for Landlords

From my interactions with landlords and fellow architects, it’s evident that these changes carry profound implications:

  • Transition in Heating Paradigms: Traditional gas boilers, once champions of heating, are now fading into the background, making way for sustainable alternatives.
  • The Advent of SAP10.2 Software: Elmhurst Energy‘s response to the shifting landscape. This sophisticated software transcends conventional energy cost assessments, capturing the essence of new builds’ energy efficiency.

5. The Legal Tapestry

Developers, brace yourselves! The new regulations are now enshrined in law. From conceptualising to habitation, these metrics are non-negotiable. Non-compliance is not only detrimental to our environment but can lead to legal ramifications.

6. EPC Scores: The Silent Influencers

Having been deeply entrenched in the property world, it’s clear that EPC scores are gaining traction. With mounting concerns over energy consumption, these scores heavily influence rental or purchase decisions, serving as the unsung heroes (or villains) of a property’s desirability.

7. The Economic Lens: Impact on Property Valuations

Anticipating market trends suggests a potential uptick in rent or sale prices for properties boasting EPC ratings of band C or higher. As the market plays catch-up, landlords must discern the long-term financial benefits of aligning with these regulations.

8. The Looming Shadow of Rising Energy Costs

The projections are stark. With the Ofgem fuel price cap speculated to soar above £3,000 by this year’s end and likely staying above £2,600 till late 2023, the clamour for energy-efficient homes will grow louder.

9. Tackling Fuel Poverty Head-On

Fuel poverty is an impending crisis, with countless UK households teetering on its brink. As architects and landlords, our responsibility extends beyond bricks and mortar. By championing energy-efficient properties, we can play a pivotal role in alleviating this looming challenge.

Conclusion: The Road Ahead for Sustainable Architecture

The architectural realm’s trajectory has never been clearer. With the new Building Regulations and SAP assessment shifts, the paradigm has undeniably changed. Landlords must not only adapt but also champion this change, ensuring their properties not only stand tall in the market but also embody the spirit of sustainability.

From my two-decade vantage point, I believe that marrying contemporary design with energy efficiency is the future – a future that is not only sustainable but also aesthetically breathtaking.

Section 1: Understanding BIM

1.1 What is BIM?

Building Information Modelling (BIM) can be defined as the “use of a shared digital representation of a built asset to facilitate design, construction, and operation processes to form a reliable basis for decisions” (BS EN ISO 19650). BIM utilises digital parametric modeling to create comprehensive architectural design models and construction workflows. It is the present and future of architecture, revolutionizing the industry.

1.2 The BIM Process in Architecture

The BIM process is all about creating a collaborative environment where all stakeholders can access and share a virtual model that contains detailed information about the building. Traditional methods involve numerous separate documents that are often lost or inaccessible. BIM eliminates these inefficiencies by providing a centralised digital model that ensures better visualisation, coordination, and development of designs. It streamlines communication and minimises errors, benefiting the entire project lifecycle.

Section 2: BIM in Architectural Practice

2.1 The Role of BIM in Architectural Services

As early adopters of BIM in the UK, we have experienced firsthand the advantages it offers in architectural services. Regardless of project scale, BIM’s 3D capabilities enable us to effectively communicate design concepts to clients and collaborators. We create digital representations of buildings that contain detailed information, from technical specifications to cost estimates, facilitating the development of construction projects. Our specialisation in using BIM for residential architecture allows us to collaborate with stakeholders, consultants, and authorities in a BIM environment.

2.2 Advantages of BIM for Developers

For property developers, BIM offers significant advantages beyond traditional architectural services. By demanding a higher level of information, developers gain better control over their projects. For example, by commissioning a point cloud laser scan survey, developers can obtain a detailed 3D digital model of the building. Through the BIM process, any changes made to the design are automatically reflected across all dimensions, ensuring consistency and reducing errors. BIM’s compatibility with the construction industry enables efficient coordination and seamless integration of project teams, resulting in cost and time savings.

2.3 Enhancing Design Communication for Homeowners

Homeowners can also benefit greatly from the implementation of BIM. Traditional floor plans and elevations often fail to convey the spatial experience of a design. However, by utilising BIM’s 3D modelling capabilities, architects can provide homeowners with a more immersive understanding of their projects. Tools like BIMx allow homeowners to explore 3D models on their phones or tablets, providing a sense of the space, flow, and atmosphere of their future homes. For those seeking an even more immersive experience, virtual reality models offer the sensation of walking through the building.

Section 3: BIM and the Building Lifecycle

3.1 Streamlining Construction and Building Control

The benefits of BIM extend beyond the planning phase, proving invaluable during construction and building control. By ensuring that all stakeholders use the same core information, BIM eliminates inconsistencies and reduces the risk of errors. The coordinated approach ensures that custom-manufactured elements, such as windows or kitchens, fit perfectly into the design, mitigating delays and additional costs. Furthermore, BIM proves indispensable for the post-construction phase, facilitating repairs, alterations, and maintenance by consolidating all relevant information in a single computer file.

3.2 BIM’s Role in Sustainable Design and Performance Monitoring

Sustainability is a key concern in modern architecture, and BIM can play a vital role in achieving environmentally conscious design and monitoring building performance. By integrating BIM with sustainable design strategies, architects can optimise energy efficiency, reduce waste, and minimise embodied carbon. Additionally, BIM enables the accumulation and sharing of data on building performance, allowing owners, architects, and local councils to make informed decisions for ongoing sustainability improvements.

Section 4: The Future of BIM

4.1 The Need for BIM in Planning Applications and Building Control

While BIM has become integral to the design and construction phases, its adoption in planning applications and building control processes is still limited. However, there is a growing consensus among architects and industry experts that BIM should be an essential component of these procedures. Integrating BIM visualisations and assessments into online planning platforms would improve coordination, reduce costs, enhance community involvement, and expedite decision-making. By incorporating building regulations into BIM effectively, architects and engineers can easily ensure compliance, resulting in faster and more efficient processes.

4.2 Overcoming Challenges and Embracing a Digital Future

Despite the potential benefits of integrating BIM into planning and building control, significant hurdles remain. These challenges encompass not only technological considerations but also the need for a cultural shift within planning departments and increased engagement with building performance. While the path towards a fully digitised planning system may be long, architects can lead the way by embracing BIM and leveraging its capabilities to design and construct buildings efficiently and sustainably.
