The New Era for Sustainable Building and Net Zero Carbon

BREEAM V7: The New Era for Sustainable Building and Net Zero Carbon 


WWith BREEAM Version 7 on the horizon, it brings a refreshed approach to sustainability standards across the built environment.

As part of this rollout, the new BREEAM Residential Manual is set to launch on the 16th April 2025, introducing key updates to criteria, evidence requirements, and a major revamp of how life cycle assessments and embodied carbon are handled.  

BREEAM (Building Research Establishment Environmental Assessment Method) is the world’s longest-established method of assessing, rating, and certifying the sustainability of buildings and has been a cornerstone of sustainable building certification since its inception in 1990.  Developed by the Building Research Establishment (BRE) in the UK, BREEAM sets the standard for best practice in sustainable design, construction, and operation across a range of building types. The assessment covers key categories such as; Energy, Water, Health & Wellbeing, Materials, Waste, Pollution, Transport, Land Use & Ecology, Managment and Innovation.  

By awarding ratings, BREEAM helps developers, designers and building owners benchmark and improve environmental performance, reduce costs, and demonstrate their commitment to sustainability and ESG principles. 

Launching in 2025, BREEAM Version 7 realigns BREEAM’s criteria with global best practices and net zero ambitions, placing Whole Life Carbon and energy performance at the center. 

This update further strengthens BREEAM’s role in demonstrating genuine sustainability across a building’s lifecycle, from early design to post-construction. It introduces new minimum standards, revised weightings, and a clear emphasis on reducing both operational and embodied emissions. Some of the key changes in BREEAM V7 regarding energy, carbon, and whole life cycle assessments are as follow: 

BREEAM V7 aligns with the latest science and global sustainability goals by focusing on reducing emissions across operational, embodied, refrigerant, and transport sources. It’s aimed at supporting the transition away from fossil fuels, streamline the path to net zero and reward projects that demonstrate measurable carbon reductions. There are also new minimum standards for ‘Excellent’ and ‘Outstanding’ ratings, as they now require more comprehensive whole life carbon strategies. 

The focus of energy-related credits shifts toward real-world performance outcomes, with increased flexibility in demonstrating compliance, the update introduces new energy performance benchmarks and promotes advanced operational energy modelling to better monitor and minimise energy usage. The new assessment issues include, but are not limited to: 

  • Ene 02 – Prediction of operational energy and carbon, encouraging early-stage modelling and third-party verification. 
  • Ene 04 – Low carbon design through emphasising building form optimisation over traditional passive design. 
  • Ene 07 – Flexible demand response, which is a new issue, modified to include all fixed building systems 
  • Ene 08 – Installed Controls, another new issue, which recognises smart controls for energy-efficient system operation. 

These changes reflect modern decarbonisation strategies, and credits are reweighted to emphasise electrification and operational energy use. 

Mat 01 has been completely overhauled to support a robust approach to embodied carbon, introducing three stages of LCA: concept, technical design, and post-construction. Credits are also now awarded based on performance against embodied carbon benchmarks, using BREEAM-recognised tools aligned with EN15978. 

There is now also a minimum credit threshold for higher BREEAM ratings to reinforce the growing emphasis on early and accurate carbon reporting. 

 

The ecology credits are now more closely aligned with biodiversity net gain goals, promoting developments that contribute positively to ecological value, with new requirements that promote sustainable site selection practices that minimise environmental impacts. The version 7 update also includes new benchmarks to align with the English Biodiversity Net Gain law and additional methodologies.  

  • Pol 01 considers the impact of refrigerants, and the criteria now mandates that all refrigerant gases have zero ozone depletion potential as a prerequisite, which highlights the importance of reducing direct greenhouse gas emissions from building operations.  
  • Pol 02 refers to local air quality, and within this update, more credits can be achieved for building with no onsite combustion, which further encourages a shift away from fossil fuel-based heating and cooling systems.  

Version 7 also introduces a consistent methodology across schemes, such as New Construction, In-Use, Refurbishment & Fit Outs, therefore improving the alignment of metrics and rating boundaries. The latest version will also extend Whole Life Carbon coverage to additional areas, such as water consumption. This more holistic approach will help to close the performance gap, ensuring users are empowered to drive measurable sustainability outcomes across an asset’s full lifecycle.  

  • Wat 01 means that the water consumption calculator has been simplified, with benchmarks now based on water consumption figures. This revised scoring scale now recognises recycled water use, in turn, promoting better water management practices 

This more holistic approach helps close the performance gap and empowers users to drive measurable sustainability outcomes across an asset’s full lifecycle. 

Version 7 introduces key enhancements to the Health & Wellbeing category, with a stronger focus on occupant comfort and long-term wellbeing. New credits have been introduced that address advanced lighting controls and the non-visual effects of light, in turn supporting circadian rhythms and promoting healthier indoor environments.  

Notably, Hea 01 Visual Comfort has been restructured to cover key elements such as glare control, daylight access, exposure to direct sunlight, and quality of views to the outside, all of which are increasingly linked to mental and physical wellbeing.  

This section also includes updated considerations for indoor air quality and acoustic performance, aligning with industry-wide recognition that occupant health is becoming a core priority, not only for those using the space, but also for investors and developers aiming to futureproof their assets.  

At Wallace Whittle, our growing ESG team integrates wellbeing strategies early in the design process, balancing occupant health with broader sustainability, energy performance, and building efficiency goals. 

BREEAM Version 7 signals a clear strategic pivot toward decarbonisation, circularity, and performance-based outcomes. By embedding whole life carbon across the core assessment framework, V7 is positioned to be a key enabler for delivering net zero carbon buildings in practice, and not just intent.

Early-stage modelling and robust data collection are now not only encouraged, but essential to achieving top-tier BREEAM ratings. The shift in weightings and minimum standards also raises the bar. The reconfiguration of credits emphasises BREEAM’s increasing alignment with other industry accreditations like NABERS UK, also improves the interoperability and long-term tracking of carbon performance across an asset’s lifecycle.

BREEAM Version 7 represents a step towards a more holistic and performance-based assessment of buildings, and as we approach the official launch of the new Residential Manual on 16 April 2025, now is the time to assess how your upcoming projects align with these changes. Whether you’re preparing for registration or evaluating your route to certification, our Sustainability Team at Wallace Whittle is here to help you navigate BREEAM V7

Resilience Under Fire: What the Heathrow Outage Reveals

News


Resilience Under Fire: What the Heathrow Outage Reveals

Resilience Under Fire: What the Heathrow Outage Reveals


Last week, we witnessed a major disturbance at Heathrow Airport due to a fire at North Hyde substation, which as a result caused widespread disruption, leading to the cancellation of nearly 1,400 flights and affecting over 200,000 passengers.  

While power was restored and the airport returned to a full schedule by Sunday, the incident has triggered investigations by the government and Heathrow itself into the cause of the outage, the response, and the broader resilience of critical national infrastructure.  

A key point emerging from the immediate aftermath is the claim by National Grid’s CEO that sufficient power was available from other substations for Heathrow to remain operational, raising questions about the airport’s preparedness and decision-making during the crisis, but it also raises questions within the industry on the importance of wider resilience across sectors, from Data Centres, to education. We spoke to Stephen Phimister, Director of Engineering at Wallace Whittle, to hear his perspective on the importance of resilience. 

Despite Heathrow having multiple electricity connections and reported on-site, the fire at the North Hyde substation appears to have caused an outage of such significance the airport had to be closed. Thus highlighting a vulnerability where a single event can cripple a critical system, even with redundancy measures in place and it’s a reminder of how easily critical infrastructure can be disrupted. 

Grid Supply Points (GSPs) play a vital role in transforming high-voltage electricity from the transmission network, typically 275kV or 132kV, down to distribution levels around 66kV or 33kV. Each GSP is generally equipped with two transformers, operating in an N+N configuration, meaning both can handle the load if one fails. A failure of a single transformer creates what is known as an N-1 condition, which the system can typically withstand. However, in the case of Heathrow, the fire not only caused the failure of the first transformer but also appears to have compromised or shut down the second transformer, resulting in an N-2 condition, complete system failure. Stephen explained.

Although Heathrow had backup diesel generators to maintain safety-critical systems, these were not sufficient to power the entire airport. According to Heathrow’s CEO, Thomas Woldbye, switching to the other two substations “takes time.” However, the head of National Grid indicated that these substations were operational and could have supplied enough power to keep the airport running. This discrepancy raises concerns about the speed and effectiveness of Heathrow’s electrical reconfiguration procedures and its overall preparedness for handling such emergencies. 

What Happens When the Lights Go Out?

This incident raises the issue of the importance of a stable electricity grid. With increasing reliance on the grid how could a major outage affect wider society, and how consequences of such an outage could ripple across multiple sectors. Here’s a generalised glimpse into how different parts of society could be affected: 

Built with resilience in mind, data centres typically operate with at least N+1 generators and uninterruptible power supplies (UPS). As demonstrated during the Heathrow incident, these facilities continued to function without interruption. 

In an N-1 scenario, hospitals are likely to stay on grid power. However, in an N-2 event, they would switch to on-site generation to ensure all critical infrastructure remains operational, albeit with the possibility of some local disruptions. You can learn more about our approach to Electrical Categorisation in Healthcare here.

These facilities often pay a premium to be supplied by two separate GSPs, ensuring continuity of operations even during significant outages. 

Most office buildings maintain only life safety systems (emergency lighting and evacuation support) during power failures. While some tenants may have their own generators to sustain limited operations, these rely on the availability of essential landlord services, such as water and sanitation, which could also be compromised during prolonged outages.

The majority of shops and offices lack backup power, leading to mass evacuations of premises and business closures.

The impact of such disruptions extends far beyond commercial and institutional sectors, affecting everyday life in numerous ways. While diesel and internal combustion engine (ICE) buses may continue operating, electric buses are left stranded once their batteries run out, as EV charging infrastructure is rarely supported by backup generators. Major railway stations may continue to function, albeit with reduced capacity, but smaller local stations, lacking on-site power support, are likely to shut down entirely.  

What can we learn from this?

The National Grid substation fire serves as a stark reminder of how fragile critical infrastructure can be and the cascading effects of a major power failure. One key takeaway is that resilience is often only noticed when it fails. The impact of incidents on the electricity grid, or even within private premises, can impact business operations. This highlights the need to consider not just primary failures but also worst-case cascading failures in resilience planning. 

The incident also emphasises that business continuity planning cannot be a one-size-fits-all approach. Underscoring the importance of regularly reviewing and testing backup systems to ensure they function properly in a crisis, and the urgent need to strengthen the protection of critical national infrastructure. This is especially important given that Heathrow is a privately operated business and not under direct government control. 

Accepting that Heathrow is a private operation, ultimately, the Heathrow outage is a wake-up call for governments, infrastructure providers, and businesses to consider the importance of resilience. As the complexity of modern systems grows, so does the need to build robust and adaptable infrastructure that can withstand challenges. Investing in resilience today is not just a precaution, it’s necessary for future safeguarding. 

It would be easy to suggest that resilience is added everywhere but that just isn’t practical or economical. Instead, consideration needs to be given to the impact of disruption on a number of factors including cost, operational impact and reputational damage. Stephen concluded.


At Wallace Whittle, we understand the importance of resilience in critical infrastructure.

UK's Net Zero Carbon Building Standard

Building for the Future: Navigating the UK Net Zero Carbon Building Standard

The UK Net Zero Carbon (UKNZC) Building Standard is an initiative that aims to tackle climate change. The pilot version of the Standard launched in September 2024. With the goal of delivering Net Zero Carbon Buildings by 2050, this voluntary standard sets ambitious new benchmarks for the built environment.  

The Standard adopts both a phased approach and sector-specific targets, understanding that achieving net zero carbon emissions in buildings is a long-term goal and requires a phased approach, but also that different building sectors have unique characteristics and challenges in achieving net zero carbon emissions, meaning there are also sector-specific targets. 

Consolidating existing standards and guidelines from organisations such as the BSI, UKGBC, LETI, RIBA, RICS, and CIBSE, The Standard establishes a unified process for achieving net-zero buildings by addressing carbon emissions across new developments and existing structures. The Standard covers retrofits, renovations, and replacements, and provides a framework for significantly reducing the carbon footprint of buildings across all sectors.  

Organisations and clients across all sectors are setting bold net-zero ambitions in line with their ESG commitments. However, the real challenge lies in delivering on these goals in a transparent and measurable way. Buildings play a critical role in this effort, both in understanding their environmental impact and achieving meaningful carbon reductions. The UKNZC Building Standard provides a clear, structured framework that leverages industry expertise to support this transition. Its introduction is a welcome step toward a more sustainable built environment.” Nick Hayes, Head of ESG & Sustainability, shared. 

Overview of The UKNZC Building Standard  

As buildings account for around 40% of the UK’s total energy consumption and 23% of greenhouse gas emissions, The UKNZC Building Standard applies to a broad range of building types, across residential, commercial, and public sectors, in attempt to reduce those emissions, and make the shift to a more sustainable environment.  

Unlike many previous industry initiatives, the UKNZC Standard takes a comprehensive and holistic approach to assess a building’s carbon impact, considering both embodied and operational carbon emissions. This ensures that carbon reduction is not treated as a one-off effort, but rather as an ongoing commitment spanning the entire lifecycle of a building.

Key Components of the Standard

The core objectives of the UKNZC Building Standard focus on reducing both embodied and operational carbon emissions across the entire life-cycle of buildings. It emphasises genuine carbon reduction over offsetting, transparency through independent validation, and encourages innovation and collaboration to achieve a sustainable, net-zero carbon built environment. Limits and reporting metrics are proposed for various key components, which become progressively more stringent each year, which in turn incentivises early action to reduce energy consumption. The proposed targets are subject to third-party verification to confirm that the buildings meet the requirements. Each component targets a critical aspect of carbon reduction and sustainability, ensuring that every aspect of a building’s emissions is considered: 

The Standard currently provides benchmarks for Upfront Embodied Carbon, referring to the emissions associated with the materials and construction processes up to the point of building completion. The limits vary based on the building type and reportable work (new build, retrofit, etc.). Future versions of the Standard are expected to include limits for Whole Life Embodied Carbon, which encompasses embodied emissions throughout a building’s life cycle, including demolition and disposal. There are also reporting requirements for the assessment of both lifecycle (whole life) and upfront embodied carbon.

The Standard sets limits for Annual Energy Use Intensity (EUI), which must be demonstrated using measured data from the building in use. Similarly to embodied carbon, these limits vary depending on the sector and building type. The Standard also requires annual operational carbon emissions and the energy intensity of specific energy end-uses to be reported for some building types. While there are no pass/fail limits for water usage, the Standard requires reporting of annual operational water use, water use intensity, and water emissions intensity. 

The Standard sets a limit on the Global Warming Potential (GWP) of refrigerants used in buildings, capped at 677 kgCO2e/kg, equivalent to the GWP of the refrigerant R32. If the total GWP of refrigerants in a building exceeds 3,000 kgCO2e (equivalent to 4.4 kg of R-32), annual emissions from refrigerant leakage for products regulated by the Kyoto Protocol must be reported. These limits will help existing regulation by phasing down fluorinated gas usage and promote the push towards ‘natural refrigerants with lower GWPs, such as CO2 or propane. 

 

The Standard requires building projects to track and report electricity usage patterns. Although there is no specific pass or fail targets yet, projects must report key data points, such as the date, time and electricity demand for periods representing the 99th, 50th, and 1st percentiles of energy use. Although the pilot version of the standard focuses on reporting, future versions may introduce specific targets, such as limits on peak winter electricity demand.

The Standard emphasises on measuring and reporting data, both for individual buildings and district systems, which are crucial for transparency and verification of net-zero claims. Centralised systems, which serve multiple buildings, can be more efficient and deliver lower adverse environmental impacts than individual systems. The Standard sets carbon intensity limits (kgCO₂e/kWh) for heating and cooling, with stricter benchmarks for new systems and requirements for reporting annual energy use and emissions.  

The Standard emphasises the use of on-site renewable generation as a crucial strategy for reducing a building’s carbon footprint and achieving net-zero targets. This aligns with broader efforts to decarbonise energy supply and reduce reliance on fossil fuels. The Standard includes specific targets for the annual amount of on-site renewable electricity generation that a building must achieve, which varies depending on the region and the type of building. The standard acknowledges that not all buildings may be able to meet the on-site generation targets in exceptional circumstances due to site constraints, and limited roof space for solar panels etc. 

This is a central requirement of the standard. All buildings are able to operate free from the use of fossil fuels, meaning eliminating the use of fossil fuels such as grid-supplied gas, oil and coal for the purposes of space and water heating, and cooking. Eliminating fossil fuel use is essential to delivering net-zero buildings, but it must be complemented by other strategies, such as reducing overall energy demand and integrating renewable energy.

The UKNZC Building Standard does not outline specific methods to achieve its goals but instead sets clear benchmarks, which can foster innovation and encourage tailored solutions.  

The Standard creates opportunities for us to work with clients, architects, and other stakeholders to deliver integrated, efficient, and forward-thinking designs. As the industry embraces this shift towards decarbonisation, our experience in MEP design, Sustainability, and ESG principles positions us to help our clients follow the pilot standard and drive meaningful change.

Strategies for Implementation

At Wallace Whittle, we believe that achieving net-zero carbon starts at the very beginning of a project. By integrating sustainability principles early into the design and planning stages, we ensure that every aspect of the building process is aligned with net-zero goals. This involves selecting sustainable materials, optimising building fabric for energy efficiency, sourcing materials locally, and incorporating renewable energy solutions from the outset.

We work closely with our clients to ensure these principles are part of the foundation, ensuring long-term sustainability from day one. Some of the strategies include:

Such as selecting sustainable materials, optimising building fabric, and incorporating renewable energy solutions from the outset. At Wallace Whittle, we work closely with our clients to ensure these principles are part of the foundation, ensuring long-term sustainability from the get-go.

Meeting net-zero carbon targets requires collaboration across all disciplines architects, engineers, contractors, and developers. We foster this collaboration by sharing knowledge, best practices, and innovative solutions and understand that achieving these ambitious goals requires a collective effort.  

To meet the targets set by the UK Net Zero Carbon Building Standard, investment in training and education is essential. We are committed to upskilling the next generation of engineers and professionals to design and calculate net-zero carbon buildings. We recognise that addressing the skills gap is critical, we therefore provide ongoing training to our team across the business with our WW:Academy. However, we also recognise that this is a wider industry challenge that requires policy support and investment at all levels, including funding for education and skills development. 

Government incentives, grants, and streamlined planning processes are crucial to supporting the transition to net-zero carbon buildings. We actively advocate for such policy support and align our work with the evolving regulatory landscape. With the new Labour 2024 Budget placing emphasis on sustainable initiatives, we are aiming to leverage these resources. 

We understand that to achieve net-zero emissions, we must think beyond efficiency and focus on sufficiency by designing buildings that meet the needs of the occupants without over-consuming resources. Many existing standards optimise “business as usual” approaches, which can still result in over-consumption and continued emissions. By rethinking our approach to consumption and resource use, we can design and deliver truly sustainable buildings that make meaningful contributions to carbon reduction goals.

As the UK Net Zero Carbon Building Standard paves the way for a more sustainable environment, it sets ambitious yet achievable benchmarks for reducing carbon emissions across all sectors. While the path to net-zero demands collaboration, innovation, and long-term commitment, it also opens unprecedented opportunities for forward-thinking consultancies like Wallace Whittle to lead by example. 

The UKNZC Building Standard is more than a framework; it is a call-to-action. Through commitment and collaboration, we can meet these ambitious goals and create a built environment that better benefits buildings, people and the planet!
