For the acquiring of BREEAM/LEED certification, a Sustainability Consultant has been appointed for the projects (Óbuda-Újlak Zrt.). The following measures have been implemented during the development in order to acquire the certification: 

All designers and contractors had to comply with the requirements set in the credit strategy, and shall provide data about the fulfilment of the requirements during design, construction and handover. 

The best is if the preliminary BREEAM/LEED credit list is supplied as an appendix of the design and construction contract(s). The contractor could propose other credits, ensuring that enough points have been attempted at the certification process. 

To provide the above, the appointed BREEAM/LEED consultant helped the design and construction process as a consultant of the Developer from the beginning –monitoring credit compliances, and giving any necessary feedback both to each involved party and the Owner of the project. The BREEAM/LEED consultant also made sure that every credit had its own responsible party, and that they were well aware of their actual task and understand them completely. 

Most of the challenges came from the fact that while the number of green building certifications is constantly increasing in Hungary, the green building rating system requirements are still not as widespread as it is in more advanced countries. Therefore, it was one of the main goals to deal with those environmental issues that are unique in the country, with this making the certification system more familiar to the participants. Since the location of the investment was not easy to reach, the capacity of the public transportation had not been sufficient, and so solving the transportation was one of the biggest challenges of the project. 

Energy efficiency is one of the key aspects of sustainability nowadays, therefore during design, attention was given to keep in mind this aspect to an extent which is allowed by the current project budget, and to provide future opportunities to later developments. 

Due to these rating systems are not known widely the requirements had to be communicated numerous times to make sure that the project members were keeping them in mind and none of the details were missed. However, as the project was developing, the team members adapted to these previously unfamiliar ideas and aspects, and it became a focus point that everybody was paying attention to.
