Teatro Real, Madrid

Decarbonisation of a monumental building

Download the case study

Fully electric system, with no need for fossil fuels
Energy savings of 48% with the installation
Maximum reliability

Project Description

The Teatro Real, located opposite the Royal Palace of Madrid, is an emblematic, monumental building which has been declared an "Asset of Cultural Interest" and is considered to be the country's leading institution for music and the performing arts.

It has an area of 80,000 m2, is 78 metres tall and dates back to 1850. One of its core values is to become the most sustainable theatre in Spain.

Challenges and solutions

The project consisted of updating the heating and cooling system for the entire building with the aim of increasing the energy efficiency and reducing the theatre's environmental impact. The new system covers all the heating, cooling and domestic hot water needs of the installation.

It is comprised of three technologies.

Water-cooled chillers, with screw compressors and speed regulators.
Air-cooled reversible heat pumps, with scroll compressors and a high seasonal energy efficiency.
Air-cooled non-reversible heat pump, with scroll compressors and a high water production temperature.

Technologies

2 x AquaSnap® 30RQP
3 x AquaForce® 30XWV
1 x AquaSnap® 61AF

The Teatro Real is the first building to be entered on the energy savings certificate register of the Energy Transition Ministry." "We have achieved this because we used products and services of the highest quality and our objective is to become a zero-consumption building.

The pillars of decarbonisation

Refrigerants with low global warming potential

The refrigerant used and the charge included in the units account for 6% of the units' global environmental impact according to our lifecycle analyses. By using refrigerants with a low global warming potential, we can directly reduce this impact.

Units with high energy efficiency

The use of energy accounts for 88% of the units' global impact. Increasing the level of energy efficiency reduces the energy consumption level and the associated CO2 emissions. It is essential that we utilise units where this parameter is as high as possible in order to reduce the indirect impact by up to 48%.

Electrification with heat pumps

The heat pump units are considered to be renewable energy sources and can help to reduce the dependency on fossil fuels. Another key aspect is that we not only need to design energy-efficient solutions, but also have to make sure that they stay efficient during their entire service life by way of maintenance plans and control systems.
