The distant heating utility line being too distant from Raadi, an expensive pipe is to be laid from the central boiler plant to ERM. Mr Külaots says ERM will not have to pay for the entire pipe, only for a section of it – as Fortum expects other objects to be erected in the area in near future, consuming both heating and cooling energy.
A rarity for Estonia, in other countries boiler plants do lucrative side business offering cooling services in the summer.
«Fortum possesses excellent knowhow with distant cooling. ERM would be among the buildings where we could offer advanced solutions, not only selling heat but offering the entire internal climate package, both heating and cooling,» said Mr Külaots.
According to RKAS press secretary Madis Idnurm, ground-sourced heating was the cheapest in 2009 when the ERM building design was drawn.
«Times have changed and new options have arisen; now, four years later, we are again analysing the various solutions. As an alternative, we are also viewing distant heating and cooling solutions based on combined cycle power stations, most favoured in the European Union,» said he.
Mr Idnurm confirmed that RKAS would organise heating and cooling procurement for the museum building.
«Pursuant to Tartu County and city plans, the new ERM building will become the centre of a new town; there will be big apartment blocks, a spa, hotels, an ice arena, meaning that Fortum must build pipelines anyway, and it would be profitable for the company to have such a big client midway,» summarises Mr Lukas.
