Buckingham Palace Road

LTi in conjunction with their key manufacturer Hidria have recently supplied the major central plant for this large commercial office building refurbishment in Buckingham Palace Road in the centre of London.

In the overall renovation of the glass office building located in the direct vicinity of the Buckingham Palace and the famous Victoria Railway Station, LTi-Hidria provided its advanced solutions for the refurbishment of the main cooling and air supply system.

LTi were awarded the contract thanks to its innovative products for efficient use of energy which have a competitive edge on the market. In collaboration with international consultancy practice Meinhardt, LTi were able to offer a unique solution to the buildings cooling load utilising low energy and recovering waste heat.

Chillers at BPR

Chillers at BPR

There are eight air cooled chillers built into the facility, with a total output cooling power of over 4 MW. Four chillers incorporate a patended free cooling system to provide low energy cooling when ambient temperatures are below 15 0C. The other four chillers incorporate heat recovery through a built in desuperheater, and this energy is used to provide pre-heated water to the boiler return.

LTi-Hidria also provided 50 air handling units for this prestigious building, each constructed to Eurovent standards and meeting energy Class-A. Eight roof-top mounted fresh air supply units incorporating high efficiency thermal wheel heat recovery, deliver treated fresh air to the plant rooms located within each core on every floor. Within each on-floor plantroom, a mixture of fresh air and office return air is then treated locally through an on-floor VAV supply AHU.

Dundalk Institute of Technology (DKIT) the Carroll’s Building

What is believed to be the world’s first Ice Storage System to be coupled with a wind turbine installation has been completed at the Dundalk Institute of Technology.

The Dundalk Institute of Technology, a forward-thinking faculty located on 90 acres and housing some 5000 students is located on the outskirts of Dundalk, the county town of County Louth.

The Carroll’s building was originally built between 1967 and 1970 as the P J Carroll’s cigarette factory, owned by the Carroll family but latterly forming part of the Rothmans Empire. The building was acquired by the Department of Education in 2001.

The factory was completely refurbished during 2009/2010, providing some 11,500m˛ of additional space forming an important new extension to the Dundalk Institute of Technology and now housing the School of Informatics, Apprenticeships and Bright Room.

Designed by the famous architects Scott Tallon Walker with mechanical services by BDP Dublin, the building has been completely transformed into a 21st Century facility for learning.

Existing already within the faculty, The Centre for Renewable Energy at Dundalk IT (CREDIT) focuses on wind energy, electricity storage and bio energy from marine sources.

In August 2005 Dundalk IT installed the world’s first large commercial turbine to be located on a college campus which currently generates approximately half of Dundalk IT’s electricity needs.

To further extend the potential for wind energy and in keeping with the philosophy of utilising storage to most effectively harvest wind power, the refurbishment incorporates 8 Calmac Model 1190 Ice Storage Tanks. These will provide cooling for the new facility.

The tanks were installed by the HVAC contractor T Bourke in the basement adjoining the refurbished building with an air cooled chiller providing the chilled water to charge the system.

Ice storage has a major role to play in the future of renewable technologies such as wind and wave power. The tanks can be charged and topped up, generally out of operational hours, depending upon the system design.  Various strategies can be employed to maximise the stored cooling energy depending upon the profile of the load to be served.

The DKIT project has been shortlisted for the CIBSE awards in the category ‘Refurbishment Project of the Year’.

LTi are pleased to have been of assistance to the consultant and contractor during this project.
