Sustainable buildings: long-term thinking and design for performance

Sustainable buildings are no longer a specialist’s responsibility. Every stakeholder in the building design, construction, management and maintenance processes can contribute to more sustainable outcomes, so long as they work towards a common goal. They key to aligning these different roles is in matching up sustainable best practice with a better commercial outlook for the project.

TFT Sustainability Associate, Oliver Morris, recently joined a RICS conference panel to discuss how this can be achieved, drawing on our experience as part of project teams and client advisers for building investors and occupiers alike.

So how can project teams and clients contribute to more sustainable buildings and the commercial outlook for their next project?

Sustainable buildings are more valuable in the long-term

Developers and investment funds are increasingly following property strategies which prioritise long-term sustainability and occupant well-being. Their confidence is bolstered by an industry which is proving its experience in delivering these outcomes but also providing greater certainty of the costs involved. The good news is that project teams engage more fully with the proper application of sustainable design and construction principles from the outset.

However, major schemes tend to embrace this process more fully than smaller or less high-profile buildings. Budget limitations can mean that projects aim to simply meet regulations, not exceed them. The problem is that regulations are evolving continually: while buildings may still be ‘compliant’ in the future, in a market of newer and higher performing buildings those assest are at risk of becoming under-valued or stranded.

Our solution is to advocate for a beyond-compliance approach at an early stage to avoid the risk of stranded assets down the line.

Designing for performance beyond compliance

TFT is a delivery partner for the Better Buildings Partnership (BBP) Design for Performance programme. The BBP aims to tackle the performance gap: the difference between how buildings are designed to perform, and how they function after the project is finished and the occupants move in.

Projects which rely on design intent alone to measure building performance, miss out on the most important indicator of success: the experience of the buildings’ users over time.

Designing for performance means gathering data on how the finished building is used by its occupants, and how well its component parts meet their needs. Operational targets can refer to aspects like energy efficiency and occupant satisfaction levels, broken down to whichever metrics are most important to the key stakeholders.

Choosing the right indicators and monitoring their performance is the best way to ensure that an asset is delivering value for its occupants, and therefore sustainable returns for its owners.

TFT contributes to World GBC sustainable renovation report

The World Green Building Council (GBC) recognises the role of renovating building stock to boost economic recovery across Europe following the COVID-19 pandemic and its wider effects. To that end, the World GBC has issued guidance and case studies on leading sustainable building renovation programmes. Published under the EU-funded BUILD UPON2 project, the Starting a Renovation Wave Report (download link) is now available.

The report summarises the World GBC’s recommended approach to sustainable renovations:

  • Starting local with best practice case studies of sustainable building renovations.
  • Use leaders and regulators, including mandatory energy performance requirements to drive building standards such as the UK’s Minimum Energy Efficiency Standards (MEES).
  • Systemic impact tracking to enable cities and local authorities to understand the outcomes of their initiatives.
  • Convene diverse stakeholders across the building and construction value chain to solve sustainable renovation barriers together.

In terms of regulation, the UK’s MEES certification is a unique proposition in global real estate, because it imposes a minimum standard for a building to achieve before it is let or sold.

TFT is often brought in to advise investors and building owners on their buildings’ operational energy use, with a view to MEES and its impact on property or portfolio’s commercial prospects. No other country has a requirement as consequential as this in the market and, looking ahead, it’s possible the UK government will go on to introduce higher standards still.

Partner and Head of Sustainability Mat Lown contributed to the report’s deep dive on MEES in the UK, explaining how our clients are responding to the regulations and expect it to tighten in the near future.

“Of the several thousand properties and transactions that we’ve been involved in, we’ve only lodged two exemptions, which is because either we were able to improve the rating by accurately modelling the property and/or by our clients carrying out cost-effective improvements to secure a compliant rating. However, with the continue to let provisions kicking in for non-domestic property in 2023 and if the minimum standard tightens to a B in 2030, then I expect it will become more challenging to meet the standard and therefore, expect there to be an increase in the number of exemptions.

The future trajectory of MEES is very much on our clients’ radar with the acceptance that the minimum standard is likely to move to a B within the next 10 years.”

Back to the workplace: The first step to safe building use

While every business disrupted by Covid-19 will be making plans to return to full operation, a return to workplaces will be tricky for SMEs or large businesses without dedicated health and safety risk management support.

Analysing a building’s layout, physical contact points, HVAC systems and more besides for potential hazards in-use can be a complex process. Government guidance states that all employers must have a full risk assessment for their business which addresses the risks of Covid-19.

This requirement is not just for offices and includes construction sites, shops or retail branches, warehouses, leisure and hospitality settings too.

Following recent risk assessments of our clients’ workplaces and of course all TFT offices, we have developed a comprehensive process for measuring and responding to risk.

Our goal is to help employees, clients and visitors feel at ease when returning to these buildings.

The process takes one to two days.

In that time, our assessments begin by discussing how the client has used the space in the past and wants to use the space in the future – to determine norms and expectations for the workforce. Then, after a physical site inspection, we will produce a full report identifying hazards, establishes who might be harmed, evaluates the risks, records the findings and provides an action plan.

It is also possible to prepare a Covid-19 risk assessment in-house.

If you are planning to take this approach, have a look at the re-opening guidelines produced by RICS, which includes steps and a helpful building checklist to follow.

The Health and Safety Executive also has detailed advice, in plain English, which explains what you need to be thinking about. Read it here.

If you have any questions while you are going through this process, or would like formal advice from one of our Chartered Health and Safety practitioners, please get in touch with Shoaib Shaikh.

How can WELL v2 inform your wellbeing strategy?

The International WELL Building Institute (IWBI) the body responsible for the WELL™ Building Standard (WELL™), has released interim guidance to prepare buildings, communities and organisations to support health and wellbeing in the workplace, in the midst of COVID-19. The advice is useful for organisations and building owners preparing to receive greater numbers back to workplaces following the latest official advice.

Though it draws on the existing WELL™ version 2, this guidance does not provide a new badge or certification. It is still very useful for understanding the most relevant WELL™ version 2 requirements in prevention and preparedness, resilience and recovery from the current pandemic. The guidelines touch on different aspects of the built environment including cleanliness, air and water quality, organisational resilience, mental health and comfort.

Following the interim guidance is the August launch of IWBI’s full Guidelines for Prevention and Preparedness, Resilience and Recovery and the graduated WELL™ v2 Standard.

In June IWBI will also launch the WELL™ Health-Safety Rating for Facility Operations and Management, which applies to a range of other facility types and market sectors including: offices, hotels, retail, grocery stores, warehouses, manufacturing, theatres, recreation, restaurants and schools.

Our team at TFT include WELL™ Accredited Professional and we are part of the recently instituted IWBI Task Force on COVID-19 and Other Respiratory Infections. We draw upon our wellbeing expertise to help organisations occupying buildings, and building owners themselves, to understand which WELL™ strategies are most appropriate for their buildings and users to maximise opportunities to enhance wellbeing.

Get in touch to find out how we can support you and your company on your workplace wellbeing journey, at: tftsustainability@tftconsultants.com and stay tuned for more news over the summer months.

Back to the workplace: safer heating, ventilation and air conditioning (HVAC) systems

To support workers who must return to offices and other workplaces while also mitigating COVID-19 spread, building owners, managers and occupiers must assess their spaces and HVAC systems with new challenges in mind. How prepared are buildings to limit the transfer of the COVID-19 virus in working environments?

Building HVAC systems are a key part of the solution for both occupied and partially-occupied buildings.

Where buildings remain vacant, please take a look at our article on managing buildings with reduced usage.

REHVA (the Federation of European Heating, Ventilation and Air Conditioning Associations) has released a guidance document on practical measures that can be applied to HVAC (Heating Ventilation and Air-Conditioning systems). This is intended to work alongside and support the government’s social distancing requirements and advice from NHS England and the World Health Organisation. The recommendations are applicable to support those employees which must travel to work, to limit the risk of infection spread between building users.

First and foremost, despite usual instincts, managers must not simply switch off plant and equipment to save energy during times of reduced usage. Anything we can do to minimise the transfer of infections in the current outbreak is a higher priority than potential energy savings (which would be minimal during the current Spring season in any case).

Research from previous epidemics shows us how viruses similar to COVID-19 can be transferred in small droplets which can in turn be caught in the air movements of ventilation systems. So, supplying as much fresh air as possible and exhausting air to atmosphere can help to remove contaminated particulates from office spaces, before they are inhaled or land on and infect surfaces.

We have outlined 12 practical measures to help prepare building services, per REHVA guidance:

1. Secure ventilation of spaces with outdoor air

Supply air should be provided from outside air wherever possible. If this is not possible, it is recommended that you consider not using these areas.

2. Switch ventilation systems to nominal speed at least 2 hours before the building usage time and switch to lower speed 2 hours after the building usage time

It is not always possible to alter speed dependant on the age of the building. Where it is not possible to change the fan speed, we recommend running at nominal speed 24/7.

3. At nights and weekends, do not switch ventilation off

Keep systems running at lower speed – May not be able to reduce speed, recommend running at full speed where this is not possible.

4. Ensure regular airing with windows (even in mechanically ventilated buildings)

Where buildings have opening windows, it is recommended that these are opened as much as possible, even if this causes some discomfort. (Note: toilets and W/C’s should always have their windows shut).

5. Keep toilet ventilation in operation 24/7

This is to create negative pressure within the toilet areas, as these areas are considered to be of higher risk. (small areas, lots of contact areas, more likely to be sneezing, toilet flushes spread particles as well). COVID-19 has been sampled within stool samples in some studies.

In this higher risk area, avoid open windows to ensure the right direction of ventilation. Building occupants should flush toilets with closed lid to further limit the amount of droplets released into the air.

6. Switch air handling units with re-circulation to 100% outdoor air

Re-circulating air may allow airborne viruses to re-enter the building. The filter media within these systems are generally not able to capture airborne particles with sufficient efficiency.

7. Inspect heat recovery equipment for leakages

This is generally to do with thermal wheels and actuators, which may not “seal” as well as they should, due to wear and tear, or faults. Any leakage may recirculate airborne virus particles as above.

8. Switch fan coils off or operate so that fans are continuously on

This is to avoid spreading the virus around internally, or where necessary keep them running to avoid the virus contaminating the fan coil unit filters and chassis.

9. Do not change heating, cooling and possible humidification set points

There is no evidence that a change in temperature or humidity will impact the proliferation or destruction of the virus. It is noted that relative humidity of 30% or less can increase the likelihood of spreading viral infections.

10. Do not plan duct cleaning for this period

Ductwork cleaning has no theoretical or proven effect on reducing the spread of the virus and could expose the workers to potential infections.

11. Replace central outdoor air and extract air filters according to your maintenance schedule

Please note: the size of the droplets typically expected are unlikely to be caught in conventional filter media installed in an office environment. The types of filters required are generally specialist, for pharmaceutical/laboratory/operating theatres.

12. Regular filter replacement and maintenance works shall be performed with common protective measures including respiratory protection

There’s no evidence that the virus is likely to be completely removed from incoming air by filtration, but it may get caught within the filter media, creating a contamination risk. In addition, filters should be “double bagged” once removed.

How can construction projects achieve circular economy ambitions?

TFT has supported UKGBC's circular economy guidance since it launched in 2018

One of the greatest opportunities about the circular economy is also its greatest challenge: success will deliver, and relies on, systemic change. In the context of sustainable construction that means investors, contractors, consultants and construction supply chains must work together and follow the same strategies to do things differently.

The UK Green Building Council (UKGBC) highlighted that, of 50,000 buildings demolished every year, much of the 90% of waste which is recovered is then recycled into less valuable products or materials, as opposed to being reused. This leaves a huge environmental and financial opportunity for our industry to resolve.

The circular economy brings clear benefits to construction, including:

  • Reduced embodied carbon
  • Reduced landfill costs
  • Help to secure planning permission more easily
  • Reduced depletion of natural resources

TFT has supported UKGBC Circular Economy guidance from its conception in 2018. We do so because we believe it is becoming the most important tool for our industry to act on replacing material waste and carbon emissions with circular principles through our day-to-day work.

The latest stage of its guidance focusses on three changes of mindset and practice. Together, they will drive us closer to a circular process which results in a better environmental impact and lower project costs too.

1. Use the circular economy to inform building design (not the other way around)

Some investors and developers – those initiating the build or works in question – are more aware of circular economy principles than others, but invariably the steps they take to achieve them must come sooner.

Material inventories and assessment tends to be part of the design process, which results in a diminished scope for designing a building for circularity, so the advantages of the process are already proportionally reduced. These steps need to begin as early as RIBA Stage 0-1.

Our circular economy consultancy typically kicks in before this stage. At this point, we can advise on setting ambitions for the work then organising and communicating the process so that design teams can understand what existing materials we are working with, and coming up with the best design to suit their re-use.

2. Procure products as a service (PaaS) to improve installation, maintenance and replacement

As well as reuse, the UKGBC has released guidance on embracing products as a service (PaaS). The principle is to create a feedback loop which engages suppliers of building products such as lighting fixtures, steel tubing or flooring on a contract basis. This way, products are installed, maintained and decommissioned for refurbishment by the supplier, as opposed to being bought, used and discarded or recycled by different parties through the building or product lifecycle.

UKGBC describes lighting as a service (LaaS) to illustrate and encourage the demand for servicing over purchasing. The model results in greater efficiencies, longer product lifetime and specialist refurbishment and reuse or, as a last resort, recycling.

This How-to Guide takes project teams which are working on projects that are replacing lighting, through the process and project teams’ roles and responsibilities for applying LaaS. This guide provides an understanding of what information is required, who to involve and at which point in the programme.

A huge advantage we see for this approach is in re-evaluating the way maintenance contracts are procured. A closed loop approach owned by the manufacturer lends itself to better-performing fittings and a fully accountable maintenance regime by the product experts.

Furthermore PaaS can help support dilapidations-free leases and more flexible models of tenancy. If components are created and installed with ease of removal, dismantling and re-use in mind, that could be one less hurdle for tenants and landlords to negotiate at the end of a lease.

3. Share circular economy responsibility across the whole design and construction team

Though the impetus will come from the client at the outset of a project, responsibility for meeting a circular ambition rests with the client’s entire delivery team. Over the course of the works, everyone from procurement, project management, main contractor, demolition contractor, design team, facilities management and inventory auditor will play a vital role and have responsibilities in progressing circular outcomes.

In our Development and Project Consultancy roles, TFT helps to orient project teams toward greater material reuse and waste reduction, using resources such as the UKGBC guidance. Doing so effectively means early involvement, as we suggest in point 1!

Sustainable building services: 3 steps for building owners and managers

This post is adapted from an article written by Mat Lown, TFT Partner and Head of Sustainability, for the CIBSE blog. Mat spoke at CIBSE’s Build2Perform event about how building surveyors and engineers could deliver sustainable and resilient buildings by working with landlords and tenants to adopt a customer experience focus.

Sustainable building is often understood in material terms – from use in construction to energy efficiency in operation. But better management of building services can contribute significantly to a building’s resilience to future climate change as well as evolving requirements of occupiers.

How can building owners create more resilient assets?

There are three ways that property managers and facilities managers can overcome unsustainable practices. Standard practice currently splits responsibility and organises maintenance in silos, resulting in a disconnection between the work of surveyors, engineers, facility and property managers. Each of these points helps to overcome this barrier to building resilience and sustainable performance.

1. Use contracts and procurement to set sustainable building priorities

As with many procedures in the building industry, contract content, structure and mobilisation is critical. Current procurement practices tend to favour the lowest bidder that often under-prices the maintenance element, while maintenance contracts and contractor performance is monitored against statutory compliance alone.

This is a short-term approach for a building which could be in use for decades, subject to a great deal of change in that period. It also does not reflect increasing market demands in relation to building performance, sustainability and user experience.

Instead, a closer and more consultative relationship with contractors can result in a better long-term strategy and delivery of more sustainable and economical outcomes. To make this work, the building owner must be clear about specifying the right maintenance and performance measures at the outset, while also engaging with the contractors’ own expertise early on to assess overall viability.

By better understanding the condition of building plant and equipment, one can determine what repairs and maintenance are required to ensure optimal performance and a long service life. Then independent verification can ensure that maintenance is undertaken and that occupiers feel they are receiving value for money.

Understanding of system design and settings is essential to ensure that the building is operating as designed thanks to its maintenance regime. 

2. Combine surveying and engineering skills for sustainable building maintenance

Surveying and engineering roles don’t always overlap, but they should work in tandem. Join up the process to mitigate wastage of equipment and time for access, and to anticipate potential problems and save money on future repair or replacement works.

For instance, if an engineer is commissioned to replace equipment on the roof, allow a surveyor to access and inspect the entire roof area and recommend simultaneous works or identify developing issues.

Even if there are no additional works resulting, surveyors and engineers can be useful consultants for a building manager. While their language and viewpoints are different, surveyors’ understanding of service charges, leases and landlord obligations can put the engineers’ deep technical expertise into context and help owners prioritise and plan for more effective maintenance.

3. Maintain sustainable building services for user experience and occupier needs

Prospective occupants now view building performance not simply in terms of energy badges and due diligence reports. Instead, they consider how spaces will function for the comfort and performance of their users, the people within it. That functionality might change as occupiers spend time in a space and adapt it to their needs, so the role of maintenance becomes crucial to adapt and optimise performance of services rather than only to keep them functioning.

That requires regular and quality dialogue between those using the building and those maintaining and managing it. Surveys and measurement tools can provide metrics, while qualitative feedback by occupiers’ employees for instance can contextualise the experiences of individuals against what they use the space for, and how that might change.

Newcastle’s The Gate: creating the future of leisure and retail

We know all too well that the retail sector is undergoing a period of transformation, but whether that means decline or rebirth seems to depend increasingly on the vision of a brand or store in question. Yes, shopping habits are changing, rendering many tricks of retail past irrelevant and unproductive, but we’re seeing new innovators and fast-moving incumbents take steps to get ahead of the curve. Familiar shopping centre and leisure brands are highly exposed to these challenges but, equally, by leveraging their large estates in the right way they can create a major advantage in a changing landscape.

The Gate is a retail and leisure complex situated in central Newcastle, which originally opened in 2002. It now plays host to 19 venues including nine food and drink outlets and five unique leisure activities including increasingly popular activity: escape rooms. With 18.65m tourists visiting Newcastle & Gateshead in 2018, a 3.5% increase from 2017[1], the Gate has had to rethink its offering to remain a popular destination for a broad range of visitors.

TFT has been lucky enough to be part of the transformation of The Gate, Newcastle, since it has been in the hands of investors The Crown Estate. As lead building consultant, we’re supporting its reinvigoration as a modern leisure destination by incorporating new and unique features to position it as a one-of-a-kind destination.

Jake Honor, project lead and Associate at TFT said:

“Since our involvement commenced on site in 2013, we have seen a shift in the retail and leisure market to becoming a much more challenging environment for landlords and tenants alike. We have also seen individual tenants more and more determined to overcome these challenges and best position themselves with a unique market offering.”

With several vacant units at the start of the 2019, it was all hands-on deck to achieve a complete makeover over the last 12 months. The transformations are clearly oriented towards a new generation of entertainment, including Cineworld’s first 4DX cinema in the North East which boasts ‘extreme sensory cinema’ capable of simulating effects like water, wind, scent, strobe lighting and motion to put you in the middle of the action. It was the largest project to date at The Gate at a value of £7m. But that’s not the only immersive entertainment on offer, with one of the largest gaming and virtual reality entertainment centre in the UK, YuMe, and The WonderBar and Mayfair Pub & Kitchen which offers guests interactive multiplayer darts tournaments, live music, sports events and more.

The 220,000sq ft retail wonderland is now able to set itself apart from its competitors by combining forward-thinking market insight and a readiness to adapt for a changing leisure sector. Supporting this transformation, TFT provided proactive and technically informed advice to ensure that the works would achieve the vision of The Crown Estate and the expectations of The Gate’s many future visitors. As more venues appraise the potential of a new generation of retail, leisure, or perhaps more accurately a hybrid of the two, the specifics of how such projects are carried out could be a deciding factor in their long-term viability.

Our projects and work streams for the site have been diverse; ranging from large scale full common area refurbishment work to individual unit enabling works, dilapidations and fit-out reviews, which has covered multiple TFT offices, disciplines and skill matrices.”

It is no secret that there is a high street crisis in the UK and the decline in shoppers is at a growing rate, but do experience-led retail offerings promise to reverse this loss? The Global Wellness Institute have reported that fitness and wellbeing industry sales have been thriving as more and more health-conscious individuals are making efforts to incorporate fitness into their daily regimes. Similarly, we are seeing more funding going into inclusive leisure activities for a wider customer profile, including disabled, elderly and young consumers.

“Looking forward we see significant potential for growth in the North East, with key infrastructure programmes rolled out with this family-friendly leisure centre paving the way for the sector, proving to be the best in its class.”

If you need a team of consultants with retail and leisure experience, and deep understanding of building materials and systems which those sectors demand, get in touch with us, we’d love to hear about your challenges.

Reliance on EPC metrics will hold back better buildings

When The Times highlighted the carbon load of prominent tall buildings on the London skyline, it drew on data gathered from those buildings’ Energy Performance Certificates (EPCs). But EPC measurements are often inaccurate and can be a red herring for building performance and sustainability.

Mat Lown, TFT Partner and Head of Sustainability, outlines a more realistic and practical approach to understand building performance.

As The Times described, there is a ‘CO2 challenge that towers over tall buildings’. But, rating the London skyline on their energy performance certificates (EPCs) figures isn’t always the best way to determine the scale of that challenge.

While I can’t fault the aims of the piece to draw attention to a major concern, the EPC is problematic. It’s a widely recognised marker of a building’s energy efficiency, but that doesn’t mean it is a reliable standard. The EPC-based CO2 emissions of the buildings listed in the article could be far greater or lower in reality. In fact, the highest-rated buildings (EPC A+) do not necessarily produce zero carbon in operation.

TFT has examined over 1,000 EPCs in London alone, which have shown the shortcomings of focusing on their ratings in isolation. We found that EPC performance predictions often overlook significant variables, instead making assumptions to ‘standardise’ ratings across different buildings. The result is that EPC certification won’t accurately consider the impact of: actual occupational densities, usage profiles and additional services such as lifts, external lighting and other equipment which isn’t included in its predictions.

EPCs may appear to be a go-to sustainability credential, but these shortcomings mean that EPC adherence must sit alongside a more viable strategy for performance measurement. We believe a more robust approach to sustainability is to assess how buildings perform in use, not just how their designs stack up.

The good news is that more advanced modelling approaches are in use, which will predict a building’s operational performance during design, construction and occupation. Emerging initiatives such as Design for Performance developed by the Better Buildings Partnership (BBP) and based on Australian NABERS experience allow owners and occupiers to understand the reality of how the building will use energy on a day-to-day basis in operation.

It means we can more accurately measure and optimise buildings for an occupier’s needs and regulatory demands, minimising energy use and boosting performance.

The EPC will continue to be a regulatory sticking point which owners will need to overcome when selling or letting. But we must also employ realistic and practical measurement to prevent red herring regulation from holding back progress towards a more sustainable built environment.

Mental health and workplace wellbeing

Mental health has become a key national concern over recent years, but was brought in to clear focus as a result of the pandemic and the lockdown restrictions which have challenged so many. As we look to the future and chart a route for returning to buildings and fully using towns and city centres, what role will mental health and workplace wellbeing play?

Government and businesses alike are trying to support the easing of lockdown restrictions with enhanced policies, products and services. On top of these initiatives, it’s important to consider how the built environment itself shapes our experience of the world, and what features we should focus on to improve workplace wellbeing and to re-open leisure and commerce venues in a better way.

They are rarely the first things people pay attention to, but many elements of our workplace wellbeing are rooted in our working environment, adding up to our day-to-day satisfaction and performance at work. Increasingly, we at TFT are engaged to measure and improve workplaces with mental and physical health as a priority.

One of the key issues to consider in supporting mental health at work is to understand what ‘restorative spaces’ are within and around the workplace and how they affect us. Research shows that access to these places encourages us to take adequate breaks during the day, restoring energy and concentration levels, so we can go back to our work refreshed.

Restorative spaces are defined by the leading industry wellbeing certification – WELL Building Standard™ v.2 – in which TFT is an accredited partner and assessor. The WELL standard describes the role of restorative spaces in the following way:

M07 – “Restorative spaces […] can help alleviate the negative effects associated with workplace fatigue or mental depletion. Through incorporation of nature, among other restorative elements, these spaces can help relieve stress and mental fatigue, support focus and encourage overall mental well-being. Exposure to plants and other natural elements has been linked with decreased levels of diastolic blood pressure, depression and anxiety; increased attentional capacity; better recovery from job stress; increased psychological well-being”[1]

M01 – “Increasing nature contact at work may offer a simple, population-based approach to enhance workplace health promotion efforts.”[2]

Indoor breakout areas and outdoor terraces that feature natural elements such as plants, flowers and natural materials, can be considered as restorative spaces. Easy access to outdoor amenities such as a nearby park, a lake or river can motivate us to go for stroll during lunch time and have an even bigger impact on our tranquillity at work and on our general wellbeing.

This effect is due to a concept known as biophilia – the innate affinity we have with other forms of life and nature. Biophilia plays a significant role in defining places and spaces for mental health and wellbeing. The presence of natural or man-made biophilic spaces within a reasonable walking distance (≤1km) that are accessible via safe and secure routes is key in supporting mental health both inside and outside the workplace.

Beneficial outdoor spaces can also include public art, museums, food markets and festivals – all of which are highlighted by the International Living Future Institute’s ‘Living Building Challenge’, citing ‘design features intended solely for human delight and the celebration of culture, spirit and place appropriate to its function and meaningfully integrate public art.’

Furthermore, the Urban Land Institute and the Centre for Active Design emphasise the importance of providing access to nature, both indoors and outdoors, which in turn facilitates social engagements and healthier lifestyles.

What are some real-life examples of these places? And do you have enough of them near you?

Our teams in Bristol and Birmingham pulled together a selection of the restorative spaces around their offices, recommended to provide the all-important outdoor and social break that we all need from time to time:
