Built to stand out

Sustainable Development

At first glance, Prologis Park Dunstable is the most sustainable development in our portfolio. DC1, a 310,000 square foot distribution centre has achieved BREEAM 2011 ‘outstanding’ accreditation and was shortlisted for a BREEAM award – two years running. Then earlier this year, its 360,000 square foot neighbour, DC2 became the first industrial building to be awarded design stage BREEAM 2014 ‘outstanding’.

It would be reasonable to ask why these two buildings are more sustainable than the rest of our portfolio. But both Dunstable distribution centres are just the same as our other new developments; both have been designed and constructed to our standard methodology.

The difference at Prologis Park Dunstable is that we are regenerating an urban brownfield site. While a number of developments have been built on brownfield land, Dunstable has distinctive characteristics. The site is in the middle of the town and it has been previously used for development.

Working closely with our supply chain, we dealt with site specific issues such as historic ground contamination and re-using demolition materials. As a result, we gained additional BREEAM credits for both buildings.

The building scored well for energy use – as it did in every other category in its BREEAM assessment. But the areas where DC1 and DC2 have gained additional credits are those associated with the site.

Towards ‘Outstanding'

All new Prologis UK buildings are designed and constructed to be sustainable and BREEAM certification is one of the metrics we use for measuring environmental performance. Providing an externally benchmarked, understandable overview, the BREEAM process informs and guides our sustainability strategy and we aim for a minimum BREEAM ‘very good’ accreditation, generally achieving ‘excellent’.

Energy efficiency is central to our strategy and we typically achieve EPC A ratings for all new developments. At DC1 at Dunstable we achieved an EPC A (12) rating, having reduced operational carbon emissions by 45% compared to 2011 Building Regulations.

At DC1, as with all new buildings, our approach was to use passive measures to reduce the need for energy; ensuring high levels of air tightness and insulation, for example, and installing rooflights to 15% of the warehouse. Where energy is essential, we used the most efficient plant possible, such as LED external lighting. 

The design team also looks at the best way to incorporate low or zero carbon technologies into buildings and at DC1 we included a 51kWP rooftop photo voltaic array, together with a SolarWall® to provide pre-heated air to the office areas and a rooftop thermal system for hot water.

At Prologis Park Dunstable we have redeveloped a previously derelict brownfield site in the middle of the town. There was a significant amount of demolition waste on the site and at DC1, we were able to re-use or recycle 97% of this, avoiding the need to send it to landfill. All the high grade aggregate for DC1 – some 23,000m3- was sourced from the site.

'Outstanding’ Achievement

Our aim is to deliver high quality buildings that will help our customers run their operations as efficiently as possible. All our buildings are designed to be the best they can be, so we are delighted that having followed our standard approach, we now have two BREEAM ‘outstanding’ buildings in our UK portfolio.
