Memòria de Sostenibilitat 2017


Energy consumption is broken down by types and uses: we use electricity for lighting, but also as fuel for vehicles. Natural gas powers the boilers for heating, while gas oil and petrol are fuels for vehicles in our fleet, and a small part loads the tanks and generators at the facilities.

Goal 11: Make cities inclusive, safe, resilient and sustainable



Consumption by type of energy (GJ)

Electricity at our facilities

Electricity consumption comes from non-renewable sources and is assigned to lighting, HVAC and the equipment and machines at the different facilities.

Electricity consumption by division (GJ/kWh)


    Important works are planned for 2018 with regard to energy efficiency in lighting to reduce electric costs.



    Since September 2017 and during 2018 a detailed study is being conducted on the consumption of the different electrical items installed in the car parks. Using a grid analyser installed at each item that consumes electricity, we will detect which items consume the most so we can thus establish a concrete action plan for each car park and each connected item. Until now we have analysed the car parks at Vergos, Cotxeres de Sarrià, Torrent de l’Olla, Sant Andreu Teatre, Gardunya, Ona Glòries, Bilbao and Navas.



    Diverse actions were carried out to improve energy at Nord Station based on optimising heat and cold air production, installing air coolants that improve pump performance, air recirculation systems and replacing valves, among others.

    We expect results to start to be seen at the end of 2018.


    Old lighting was exchanged for LED lights at different spaces in the Zoo, concretely in the Titi Gallery and the Gorilla Exhibit, the most important to achieve higher levels of energy efficiency and reduce electricity consumption. Modules were also installed to measure consumption at different exhibits (Land of Dragons, Dolphinarium, Giraffes, new Lion building).

The gas that warms us

Natural gas consumption heats the different facilities. Gas consumptions refer to the Olympic Ring and Zoo divisions.

At the Zoo consumption heeds the needs for the animal exhibits. In general, this consumption is constant and similar over the years, although it may vary in some cases depending on the weather and construction or upgrading of new facilities. In 2017 HVAC and thermal insulation improvements were made in the large primate pavilion. 

Consumption at the Olympic Ring is related to the number and type of events held at the facilities, which is why consumption may fluctuate from one year to the next without necessarily being linked to upgrading equipment or modification of the facilities. 

Natural gas consumption by division (GJ/kWh)

The petrol that moves us

Our fleet is comprised of different types of vehicles: bicycles, cars, motorbikes, vans and tow trucks. Although the fleet is primarily made up of vehicles that use fossil fuels, we have the challenge of reducing our environmental impact. For this reason, we are electrifying the fleet and progressively changing the vehicles. This year we added 74 electric motorbikes, distributed over different units, and also for travel by people in corporate services.

Throughout the year we developed over 10 global actions for sustainability. Read about them!
