During the refurbishment and redevelopment of The Record Hall, Workspace made BREEAM Excellent a priority from the outset, exceeding planning requirements. The whole project team worked collaboratively to successfully embed sustainability into every aspect of the scheme and create a location of choice for occupiers.

At Workspace, sustainability is embedded throughout the business, and is increasingly embraced by Workspace customers, who want to ensure they are having a positive impact on the environment and wider community.

At The Record Hall, Workspace is transforming a former record depository to create 5,400m2 of modern office and studio space over six floors, with high-tech meeting rooms, a co-working lounge, a café and roof terraces offering views across the City.  Located in the Hatton Garden Conservation Area, 14% of the scheme is designated for jewellery businesses, reflecting the area’s heritage as London's jewellery district.

The project involves refurbishing an existing four-storey office building and adding a two-storey roof extension. The team includes Karakusevic Carson Architects, building services engineers Max Fordham, main contractor HG Construction, cost consultant Stace and structural engineer Thornton Tomasetti, which also provides BREEAM assessor services. All have strong environmental credentials and have worked with Workspace on other BREEAM projects. 

The Record Hall achieved BREEAM Excellent Design Stage, scoring particularly highly for transport, land use and ecology. The project team is now working towards Excellent for the Post Construction Stage (final). Design features and construction plans are outlined below:

Transport

Cycle facilities exceed BREEAM requirements, with 51 secure indoor cycle spaces, 54 lockers, six showers and changing facilities.
Travel Plan developed to encourage sustainable travel through information, facilities and incentives.
Highest possible rating on Transport for London's Public Transport Accessibility Level (6b), with Farringdon, Chancery Lane, Holborn, City Thameslink and Blackfriars stations all within walking distance.

Land use and ecology

Ecologist appointed at an early stage of design, reviewing ecological value and opportunities.
279m2 of green roof space added on two levels, with a 100% wildflower turf vegetation layer.
Habitats and planting designed to support regional and national biodiversity action plans, including the London Biodiversity Action Plan e.g. Leontodon autumnalis, a plant specific to a rare UK beetle, Olibrus flavicornis.
Contractor appointing a biodiversity champion, delivering training to the site team on how to protect ecology, and reporting ecology actions.

Health and wellbeing

All lighting specified in line with best practice guidelines for visual performance and comfort (CIBSE Code for Lighting 2012 and Lighting Guides 6 and 7).
Lighting zoned and controllable in office areas, so occupiers can easily adjust light levels.
High frequency ballasts on all fluorescent lamps to reduce the risk of flickering.
Blinds with side cords on windows, so occupiers can control shading.
Improved air quality, with air intake designed to avoid key external pollution sources.
Good thermal comfort levels in office areas, with all office areas actively cooled (CIBSE AM11).
Temperature controls in each occupied space, so levels can be adjusted for different users’ needs.
Reduced noise levels through insulation, outperforming BREEAM requirements of 50 dB LAeq in all internal areas.

Energy

Zero carbon energy from 85m2 array of 230W solar photovoltaic panels, supplied by EvoEnergy, chosen based on compliance with the specification, trading record and costs.
Low carbon energy from reversible air source heat pumps.
Energy efficient lifts that operate in standby mode during off peak and idle times, with variable speed drive motors and electricity generated by the lift movement returned to the site.
Extensive energy sub-metering, so the building team and occupiers can monitor and proactively manage energy use. Occupiers will be given logins to view their energy profiles directly.
Energy efficient internal and external lighting throughout, in conjunction with daylight sensors and presence detection to further reduce consumption.
Mix of mechanical ventilation with heat recovery and natural ventilation to reduce emissions.

Water

Toilets with effective flush of three litres or less, achieving the maximum BREEAM credits.
Taps fitted with two litres per min Eco spray outlet and showers not exceeding nine litres per minute.
Water metering and leak detection, so the building team can monitor and proactively manage consumption.
Proximity detection shut-off system in all toilet areas to prevent waste water from minor leaks by shutting off the supply when no one is there.
Materials
At least 80% of timber certified sustainably sourced.
At least 80% of key building elements responsibly sourced, as defined by the Green Guide to Specification, with A/A+ rated elements including plasterboard, steelwork and vinyl flooring.
Masonry brickwork façade retained, reducing lifecycle emissions.
Thermal insulation products with low embodied impact relative to their thermal properties, determined by the Green Guide to Specification, and responsibly sourced.
Exposed building and landscape areas protected to minimise the frequency of use of replacement materials.

Waste

Less than 6.5 tonnes or 12.9m3 of waste to be generated per 100m2 gross internal floor area – reducing waste through careful procurement (e.g. ordering precise quantities needed and purchasing plasterboard at 2.7m high to suit storey height) and use of prefabricated materials (e.g. precast brick faced panels).
At least 90% of demolition waste and 75% of construction waste (by weight) to be diverted from landfill, with all waste sent to a registered sorting station.
Onsite recycling facilities for occupiers in a central, dedicated space.

Management

Commissioning in line with current best practice and included in main contract preliminaries.
Green leases covering heating, cooling, lighting, sustainable travel, alterations and data sharing.
Building User Guide to support occupiers in operating their areas efficiently.
43/50 Considerate Constructors Scheme score, reflecting care about appearance, community, environment, safety and workforce.

Financials

£63,200 investment in the green roof.
£1,200 for BREEAM certificates.
Enhanced occupier appeal, contributing to rental income.
Reduced construction costs by retaining building structure and façade.
Energy cost savings for occupiers.

Benefits

Upgrading office space and adding 582m2 of café space and 279m2 of roof terraces.
Extending the building’s useful life.
Enhancing sustainability credentials, through BREEAM Excellent and an EPC score of B-26, up from C before the project.
Preventing exposure to the Minimum Energy Efficiency Standards, which come into force in 2018.
