Imjin Barracks Single Living Accommodation (SLA)

Imjin Barracks is the first site to benefit from a new wave of Net Zero Carbon construction, which is delivering major improvements to the design and delivery of the Army’s SLA. The Imjin Barracks SLA provides modern, sustainable accommodation for Army personnel based at the Headquarters of the Allied Rapid Reaction Corps (ARRC).

The three-storey building, which includes a Counter-Terrorism Measures (CTM) level 2 compliant roof, was constructed via Modern Methods of Construction (MMC). Using 3D volumetric construction, units arrived on site up to 90% complete, allowing for significantly faster programme delivery, increased security measures thanks to fewer personnel needed on site, little disruption to an active military location and heightened quality assurance.

The new SLA comprises 69 single en suite bedrooms, alongside communal living and dining facilities, kitchens, drying rooms and utility rooms. The bedrooms have been equipped with full-size double beds and designed to maximise storage space provided for their occupants, while shared kitchens are fitted with state-of-the-art hobs and combination microwaves, bespoke fridges with individual coded compartments for cold food storage and lockers for dry food storage.

The SLA is a cognitive building, which complies with a BACS Class A system (BS EN ISO 52120) and scores over 95% in the Smart Readiness Indicator (SRI), making it one of the most advanced buildings in Europe for SMART building control. In other words, an integrated approach has been taken to how the building is monitored and controlled to improve occupant experience and provide actionable insights that optimise energy and maintenance.

The building, which has achieved Defence Related Environmental Assessment Methodology (DREAM) ‘Excellent’ and EPC 2 ratings, is currently generating over 21,000 data points (including humidity, door and window contacts, sound levels, temperature, and more) because of an enhanced sensing and metering strategy. These points, which are all accessible via a single SMART building technology platform, are being used to control systems such as heating, lighting and ventilation in order to minimise the energy consumption spent from human error. Large volumes of real time data will allow the facilities management team to understand the occupant experience and evolve these control strategies.

Each bedroom is equipped with a fully programmable touch screen, that allows the occupant to customise their heating preferences, increase ventilation and identify operational issues such as leaks in their bathrooms. The screens also provide the occupant with information on their monthly electricity and heating consumption, which is also ranked on a building-wide leaderboard. Using gamification strategies, the hope is to incentivise and motivate occupants to make conscious changes to improve their consumption and move up the rankings.

The system also presents a fault console to the facilities management team, allowing dynamic maintenance based on equipment usage and the generation of meaningful schedules to check and replace equipment where needed.

The building also includes photovoltaic panels on the roof and connected walkway, air source heat pumps for heating and hot water and Nano Crystal Cell Battery technology, which can hold up to 1327 kWh of energy. The system will always maintain a minimum energy level to ensure the resilience of the building in the event of any grid failure. It is also anticipated that the battery will enable the building to go entirely off grid during the summer months.

The £13M project was delivered for the Army by the Defence Infrastructure Organisation (DIO), contracting to off-site construction specialist Reds10 and design and engineering consultants Arcadis.
