Iberdrola España implements an aerothermal system combined with solar panels in a nursery school in Guadalajara − generating savings of 75%

• This sustainable system is four times more efficient than conventional boilers and avoids the emission of 18 tonnes of CO₂ per year.

Iberdrola España − a leader in renewable energy in this country − has implemented an innovative aerothermal Enlace externo, se abre en ventana nueva. system combined with solar panels at the "La Casa de Mamá" nursery school in Guadalajara, moving towards a more sustainable and efficient future. This project seeks to provide a comprehensive solution for air conditioning and domestic hot water supply (DHW), which significantly reduces CO₂ emissions and energy costs, generating savings of nearly 75% per year. 

Aerothermal energy is an advanced technology that harnesses the energy of the outside air to generate heating in winter, cooling in summer and hot water all year round. This sustainable system is four times more efficient than conventional boilers and reduces CO₂ emissions by 78% − avoiding the emission of 18 tonnes of CO2 per year. 

Project details

The school, with a surface area of 600 square metres, initially had a gas boiler for underfloor heating, DHW and indoor pool heating and cooling, with an annual consumption of 91 MWh and emissions of 23 tonnes of CO₂. In response, Iberdrola España has replaced the gas boiler with aerothermal equipment, installed a Smart Solar photovoltaic system with 30 solar panels and a new underfloor cooling service for air conditioning in summer. 

The project has been a turnkey project, including the legal requirements needed for the new installation, total dismantling of the old boilers and has benefited from a subsidy for installing renewable energies under RD1124, which represents approximately 35% of the investment cost.

Project results

Thanks to this project, the total heating and cooling have been successfully achieved, including heating, cooling, DHW and pool heating and cooling with a new thermal power of 32 kW and an annual consumption of 30 MWh, to which the photovoltaic contribution should be added. 

This will reduce annual energy costs from nearly €21,000 to €7,000, with an energy saving of 75%. It will also generate savings in the maintenance of the installations and will reduce CO₂ emissions.

Committed to sustainability

Iberdrola España reaffirms its commitment to sustainability and technological innovation. This project, "La Casa de Mamá" in Guadalajara not only improves energy efficiency and reduces emissions, but also provides a more comfortable and safer environment for children.
