Developing sustainable buildings
Sustainable buildings are more attractive to occupiers, cost less to run and are less likely to become obsolete, enhancing the long-term value of our property portfolio.
Building sustainable workplaces
Featured sustainability downloads
To build resilient buildings we must reduce the resources used and carbon emitted, both during the development process and when in use by our occupiers. To be attractive to occupiers, we ensure wellbeing and improvements to the public realm are considered early in our designs.
In London, local authorities are including ambitious sustainability measures in their planning strategies. We welcome this approach and seek to exceed current regulatory requirements, using BREEAM and SKA to help us achieve high standards of sustainable design.
Our Sustainable Development Brief sets out our aspirations for each step of the design process in respect of energy, water, waste, materials sourcing, transport, ecology, occupiers, community, emissions, wellbeing and supply chain. Our Sustainability Tracker helps us monitor progress against the brief throughout the development.
Striving for excellence
We use BREEAM as our sustainability assessment criteria, requiring all new builds to achieve a BREEAM Excellent rating. For major refurbishments we target BREEAM Excellent or Very Good depending on the scale and extent of the work. For refurbishments under 50,000 sq ft we use the RICS SKA system and look to achieve gold or silver ratings depending on the project.
95 Wigmore Street
A seven floor multi-let commercial office building. The property achieved a BREEAM Excellent and an EPC Rating of B. 82 cycle spaces were included in the development along with ten showers. A biodiversity action plan was put in place with sparrow, bumblebee nest and insect boxes installed and rainwater irrigation for planting.
240 Blackfriars Road
A multi-let commercial office building, with 19 floors. The property achieved a BREEAM Excellent and an EPC Rating of B. The building exceeded Building Regulations energy efficiency requirements by 28%.
240 Blackfriars Road was our first development constructed using Building Information Modelling (BIM) technology, enabling construction rehearsals to be undertaken in a 4D timeline to identify sequencing and logistics issues and ensure an efficient programme.
12/14 New Fetter Lane
A 12 floor commercial office, pre-let to Bird & Bird, the property was forward sold to TIAA-CREF in December 2014. The property achieved BREEAM Excellent with a score of 76.3% and outperformed BREEAM requirements on water consumption by 40% equating to an estimated saving of 17 litres per person per day. The site was awarded the Considerate Constructors Scheme Gold award for two years running.
30 Broadwick Street
30 Broadwick Street Completed in November 2016 with six floors of office accommodation. The property achieved a BREEAM Excellent rating, an EPC rating of A, benefits from mixed mode ventilation and has full FSC Chain of Custody Project Certification.
For the first time, Building Information Modelling (BIM) technology, traditionally used for building design and construction, has been utilised in the delivery of facilities management services for the property (planning the full operational life of the building). The BIM model will be used by the facilities management team and our mechanical and electrical contractor to realise cost benefits and improve service delivery.
A 418,700 sq ft mixed use scheme with commercial, residential and retail elements. The office elements will achieve BREEAM Excellent, with the residential flats targeted to achieve Code for Sustainable Homes Level 4. The property benefits from a Combined Heat and Power system and 400 sq m of photovoltaic panels, and greywater systems for the apartments have been installed with rainwater harvesting to irrigate the green and brown roofs and the public garden.
Using smart technology
Building Information Modelling (BIM) is used on all our major development sites to improve collaboration between designers and contractors, so we can:
- Identify and solve design issues in a virtual environment before starting on site
- Reduce waste on site by improved sequencing and increased offsite manufacture
- Improve the energy efficiency of the building through enhanced energy modelling
Reducing energy consumption
We use renewable energy and energy efficient solutions in the design of our mechanical and electrical services, such as solar hot water heating, photovoltaic panels and energy efficient cooling and heating technology.
Diverting waste from landfill
waste diverted from landfill
We set stretching targets for demolition and construction waste management to require the diversion of 95% of non-hazardous demolition and construction waste from landfill. During the year to March 2017 we achieved a diversion rate of over 95%.
Maximising water efficiency
of water per person per day saved through water efficiency at 12/14 New Fetter Lane
As part of design we look to meet and where possible exceed best practice guidelines on water conservation using a variety of water efficient devices. During the construction process we also monitor the volume of water used.
For more information on environmental data related to our developments see Our Performance.
Sourcing materials responsibly
We target FSC project certification on all new build developments and major refurbishments. At smaller refurbishments we specify that 90% of timber must be FSC certified. For all other construction products and materials, we support and give preference to the procurement of products from suppliers who are able to demonstrate compliance with a recognised responsible sourcing scheme, certified by a third party.
Preserving and developing ecology
Urban greening measures such as green and brown roofs, green walls and planters, bird boxes and insect boxes all serve to improve biodiversity. They also help mitigate the heat island effect in cities. We ensure that biodiversity measures are considered early in the design process and, once in place, we provide information to occupiers on how to look after them when we have left the site.
Designing in Wellbeing
We integrate relevant health and wellbeing measures during the design process, considering matters such as air quality, views out, lighting design and how we can encourage physical activity.
Working collaboratively with suppliers and occupiers
Communication is the key to success. We produce a Tenant Action and Neighbourhood Plan to understand and minimise potential disruption that may be caused during our developments.
At key points during the design process we hold ‘Soft Landings Meetings’ to bring the design and building management teams together to discuss and exchange ideas. This process continues until after practical completion to ensure a smooth transition of the building between construction, commissioning, fit-out and occupancy.
Post Occupancy Evaluation surveys of our completed developments, which include extensive consultation with occupiers.
James Pellatt Head of Projects
Our Post Occupancy Evaluation surveys have proved invaluable in providing feedback to our design and project teams working on other developments and have helped inform our Soft Landings process.
Our Supplier Code of Conduct is issued to all our contractors and suppliers to provide clear guidance on our expectations in connection with:
- Protecting our environment
- Implementing high standards in health and safety
- Looking after people
- Preventing child labour
- Encouraging apprenticeships
- Avoiding forced labour
- Wage and benefits
- Working hours
- Freedom of association and collective bargaining
- Working in our community
Our plans for the future
- Update our Sustainable Development Brief to include clear guidance on measures to enhance tenant wellbeing through improved design.
- Review the effectiveness of our soft landings process at completed developments.
- Facilitate apprenticeships and work experience across our development projects.
- Undertake a social value report to support a planning application for a forthcoming development.
