The entire heating, cooling and hot water systems were removed from the building and a development plan agreed that would raise the bar on every existing standard that is energy related beyond best practice to create a solution to fit the concepts of EXEED.

While this plan would add millions to the renovation cost, natural energy at zero cost would repay the loan with a fast return on investment.

The government energy agency Seai got behind the initiative offering financial support on the precondition of performance testing when operational so that the system could become a flagship for new development.

Standards were raised, new methods were developed and energy performance was interlinked with consumption by simply exchanging energy to areas in need from areas in excess, the energy exchange system applied takes renewable energy and low carbon design to a whole new level.

To insure nothing gets wasted, the energy transport network through the building is engineered to zero thermal loss allowing the pipework system act as storage in a unique design strategy.

The road to creating this low energy hotel began with rigorous testing on site which was boosted by the discovery of a massive energy reserve in the form of an underground river.

This discovery was inspirational in determining the mechanical design for the thermal energy system required for cooling and heating the building capable of using natural energy reserve.

The test well drilled to eighty meters deep at the rear of the hotel provides energy at 11°c for passive cooling the south side and having passed through the network rises to 16°c returning with enough energy to heat the north side without burning fuel.

The plant room, which was excavated under the basement car park, is an energy exchange system consisting mostly of pumps trained to follow performance routines.

Electricity to power these pumps and building is produced on site in a gas turbine to eliminate massive energy losses on electricity from the network.

Cooling the turbine produces the hot water for the hotel which is stored locally on each floor for instant use.

When the process of heating and cooling begins the system simply swaps energy from areas where there is too much to areas that require heat through an energy management system designed specially to eliminate wasting energy without compromising on comfort.

This means there are no emissions or harmful pollution created on site, only a small amount of energy is required to pump natural energy that already exists and the standby system is only being used during servicing.

The Iveagh Garden hotel electrical design minimizes electrical power consumption on all equipment that requires energy, lighting systems inside and outside were designed using LED low power lighting to enhance the desired result.

The entire building envelope has been sealed and insulated and existing glazing replaced to modern conformity with ventilation continuously monitored to insure clean fresh air for comfort living and energy exchange to prevent waste.

Water services were redesigned so that waste water operates gravity with no pumping energy required and lift systems replaced with low energy operating systems to all floors.

Enjoy a stay in the Iveagh Garden Hotel, realising every effort has been made to insure your stay is a positive effect on climate change, helping reduce global warming despite the comfort experience provided.

Management selected Ochsner Engineering as a key player in design alongside GNCE and Eurotech also delivered the renewable energy systems having previously teamed up with the Mc Gill family to apply renewable solutions in their Harcourt Hotel building.
