One office building, three building certificates
A bit about the building
The Ombu building opened in 2022 after a renovation and repurpose of the industrial warehouse and belonging annex, built on the same premises already in 1905. The renovated building is in part housing a modern office, designed with sustainability clear in mind. The office is then integrated with 10 000 square meters of a new-built urban landscape and a 12 400 square meters courtyard offering an option to work outdoors.
The original load-bearing structure as well as the brick envelope was preserved during the renovation process. Also the historic roof was possible to keep above the lightweight wooden construction built inside the building.

Sustainability from recycling to energy saving
The carbon footprint and the project's impact on the environment were in all aspects of the development been carefully measured and controlled. A perhaps more trivial piece of information, but still, there were 350 trees and 28 000 plants provided to the green courtyard and they are all of various local species with low water requirements. From a more noticable angle, the Norman Foster Foundation collaborated with the Madrid-based Ortiz León Arquitectos on the project as a whole, and a goal was set to recycle 75% of the waste generated during the construction process and it was decided to use materials and products which could generate a 35-40% energy save.

More insights in our energy efficiency guideLEED, WELL and Net Zero Energy
World known building certificates such as BREEAM, LEED and WELL, are with separate approaches driving developments in energy efficiency and cost-savings, human health and well-being in relation to buildings and indoor environments. There are also a number of national, regional and local certification standards which can lead the way when a building project has set challenging targets in relation to sustainability and indoor climate.
The Ombu building has an energy rating which complies with the European Commission's Nearly Zero Energy Building standards and the project is pre-certified LEED Platinum. The building is fulfils the criteria to reach the WELL Gold level and it is registered to obtain the Net Zero Energy certificate awarded by the International Living Future Institute in the USA.
Swegon contributes to sustainability
One way to commit to the goal of high sustainability standards in a building, is to select products and solutions which put a minimum pressure on the environment. As for many other companies and governmental bodies, we at Swegon have for long worked hard to develop products with significantly reduced operational carbon, meaning, products with a minimal energy requirement for ventilation, heating and air conditioning in buildings.
We are honored to be key supplier in the Ombu project. The units we have provided are the Omicron Rev S4, an air sourced high efficiency multifunctional unit with a 4-pipe system, and two air-cooled modular chillers with reversible heat pumps and scroll compressors called Tetris 2 HP. Two energy efficient units, well suited for the task at hand in the Ombú Building.
