Eaton-Williams delivers controlled environmental solution for new Life Sciences building at the University of Bristol

New Life Sciences building at the University of BristolWhen the University of Bristol began the development of its new Life Sciences building, it had a compelling vision to provide a world class facility for scientific research to tackle key issues such as environmental conservation and food security.

The new £56.5million, 13,500m2 facility that opened in October 2014 has achieved those goals. It also has achieved a world-class environment inside the facility due in part to 14 custom-built MODUCEL® air handlers from Eaton-Williams Group Limited.

Professor Eric Thomas Vice Chancellor of the university says, “Many of tomorrow's advances will come from the Life Sciences and so it is fitting that this significant new building will be the hub for our world-renowned research and teaching in this area."

Working in partnership with NG Bailey, one of the UK’s leading engineering, IT and facilities services businesses; Eaton-Williams designed the custom air handlers to provide comfort cooling throughout the building which houses the School of Biological Sciences. The building comprises two impressive parallel four-to-six storey wings with two adjoining basement levels, research laboratories, state-of-the-art teaching laboratories, acoustic chambers, a new Biosciences library, write-up spaces, seminar rooms, plus offices and various administrative areas which are accessed by a bridge that links across an atrium space.

The exterior of the building has made extensive use of anodised aluminium cladding which was specified to provide a durable and modern finish. The building also features a vertical living wall, standing over 20 metres above street level, that is home to 11 different species of plants, and includes boxes for birds and bats. A state-of-the-art greenhouse is located on top of the building and is capable of recreating tropical conditions thanks to controlled light, humidity and temperature.

Universities, like many other organisations, face greater demands to achieve ‘more with less’, not just by making greater use of space, but also by improving energy efficiency to minimise energy usage to meet CRC targets and reduce carbon emissions.

Eaton-Williams® LKP air handling systems were specified on the basis of meeting the university’s criteria for energy efficient solutions. Another advantage of the LKP air handlers is that they characterise the Eaton-Williams approach to engineering, which focuses on meeting customers’ requirements for solutions that minimise space and maintenance requirements, whilst addressing environmental parameters.

The systems were custom built and tested at the Eaton-Williams plant in Stoke and manufactured in line with the Part L Building Regulations for new buildings. The units were designed and delivered over a three-month period and delivered to site in modules for easy on-site assembly.

Scope of supply:

14 internal Eaton-Williams LKP units plus one remote extract reclaim coil     

Two types of reclaim system:

  1. Supply / extract reclaim coils   minimum efficiency 40 %

Seven supply units with heat reclaim coils
Air volumes from below 1.0 m3/s to 6.5 m3/s
Units comprise - panel and F7 bag filters / plug fan / reclaim coil / LPHW reheat coil / chilled water cooling coil
Larger units have split coils with connections to one side to facilitate removal within a restricted plant space.
Twin plug fans selected were appropriate to suit unit aspect.

  1. Four extract units with heat reclaim coils

Air volumes from 1.2 m3/s to 6.1 m3/s
Units comprise - damper / F7 bag filters / reclaim coil / plug fan

One remote supply duct type reclaim coil - 10.8 m3/s

The design combined a number of supply reclaim coils with matched extract coils forming a common pipework circuit:

  • Clean system - five supply AHU reclaim coils matched with three extract AHU reclaim coils
  • Office system - single supply reclaim coil matched with single extract coil within AHUs
  • Dirty system - duct mounted supply reclaim coil matched with two extract AHU mounted reclaim coils

Heat wheels (minimum efficiency 70 %)
Three combined supply and extract units with heat wheel recovery

New Life Sciences building at the University of BristolThe LKP range of fully optionalised air handlers are designed to satisfy customer demands for high specification units whilst addressing the need for reduced maintenance and total life costs. Built around a modular concept, the systems offer full optimisation that can satisfy the most exacting project criteria. With 14 models in the product range, there is a solution suitable for any application.

“Eaton-Williams can offer a diverse range of models in the LKP range which can provide customers with the benefits of a bespoke system, but in a standardised format,” says Guy Hutchins, Eaton-Williams’ Sales Director.

A robust profile frame forms the basic design of the LKP that also uses double-skinned infill panels of 25mm, 45mm and 50mm thickness. The panels are formed from two layers of sheet steel separated by infill material that offers excellent thermal and acoustic properties.

The manufacturing process ensures a smooth interior surface that minimises frictional losses and provides a positive air-seal where panels are fitted to the frames.

Features include:

  • Boxed Pentapost frames
  • High strength double skin panels
  • Full length base channel or feet
  • Galvanised or coated finish
  • Indoor or weatherproof designs
  • Burner/heat recovery options
  • Flat pack or kit form configuration
  • Warranty options for full life
  • Modular casing construction providing adaptation for project requirements
  • High standard specification giving long life expectancy and low ‘life cost’
  • In-house computerised selection
  • Frame options available to meet individual design specifications
