Case Study: TATA Technologies, UK

Tata Technologies, owner of Jaguar Land Rover, constructed a new 30 million dollar European Innovation Headquarters in Leamington Spa, United Kingdom. The three story steel framed, 63,000 sq. ft office building will house nearly 600 staff working in emerging vehicle technologies.

“These new headquarters showcase our ambition to continue to grow and expand Tata Technologies’ operations in the UK and Europe. The development marks an exciting new chapter in the company’s support of engineering excellence across the region and will create an additional 200 jobs opportunities at all levels, from graduate to senior roles.”

The Challenge
Tata Technologies needed the Innovation Headquarters to be both energy efficient and sustainable, and this could prove difficult to accomplish in a three story office building.

The Solution
Air2O developed a hybrid air conditioning system that employed the benefits of a two-stage evaporative cooling system (IDEC), together with a reduced load refrigerant coil to deliver a highly efficient cooling strategy. The cooling was achieved by the addition of an Air2O hybrid air conditioning unit connected to the fresh air intake section of each of the six air handling units. The Air2O hybrid packaged unit is complete with indirect and direct evaporative cooling functions together with the DX coil, compressor and condenser all housed integral to the unit to maximize space. Each unit will deliver approximately 11,000 cfm of air with a maximum supply air temperature of 59°f. The internal set point will be 72°f and the internal maximum allowable condition in the summer months would be 78°f.

The Benefit
By operating the indirect evaporative cooling coil and the DX coil together, the DX coil and subsequent compressor size was reduced by nearly 50% and since the cooling strategy is 100% fresh air, it creates a very fresh and invigorating environment, compared to a traditional air conditioning systems where a large percentage of the air is recirculated. Air2O hybrid cooling technology uses a fraction of energy of a conventional DX or chilled water cooling. Using this approach can create approximate savings of around 50% in terms of both running costs and refrigerant load.
