In 2020, the City Council of the City of Munich obliged the building department to design the green roofs of all new buildings as biodiversity roofs wherever possible and to green at least 30% of the facades.
Mr. Otto Efler will report on the experiences of the Horticulture Building Department on how successfully this obligation has been implemented since 2020. Together with some other colleagues, we will present current projects.

Markus Schäf will then report on the current status of the BDA's plans for the A7. And about the BDLA Bavaria symposium on climate in fall 2022.

The meeting will take place online. Access data can be obtained from Markus Schäf, head of the working group (see below).

By popular request, this year's first meeting will take place without a speaker or presentation. The focus of the evening will be the preparation of an annual program. Among other things, a symposium on sustainability and climate protection in landscape architecture is planned for fall 2022.

The meeting will take place online. Access data can be obtained from Markus Schäf, head of the working group (see below).

It is planned to invite Mr. Grau from Ramboll Studio Dreiseitl, who have developed an online application for the evaluation and comparability of plans with regard to their sustainability criteria.

The session will take place in a hybrid format. Registrations are possible via Markus Schäf, head of the working group.

Mr. Villar from CL Map GmbH explains everything about DGNB certifications (German Sustainable Building Council). He is a certified DGNB and Leed consultant. Mr. Lang from LangLangLang will also add a few words about the DGNB from the client's point of view.

The following questions will be discussed:

• Content of the DGNB certification, especially content regarding open spaces that we can influence
• Advantages for building owners, reasons for certification
• Can we use the certification to plan and create outdoor spaces that are more sustainable and biodiverse?
• Differentiation and differences to other certifications, e.g. Leed
• Development of DGNB: Will the content change in the future (expansion?), dissemination, will it become standard at some point?

In the Climate Working Group, landscape architects from offices throughout Bavaria, as well as representatives of authorities from many cities throughout Germany, A4F and, for example, Green City Munich discuss climate protection. There is a lively exchange of experiences on the new planning requirements in climate protection.

After a longer break due to coronavirus, the bdla Bayern Climate Working Group, which was founded in 2019, resumed its work in March 2021. The topic of climate protection is now being discussed and implemented everywhere. In the short to medium term, the working group will therefore focus primarily on current developments in climate protection and work out which next steps are expedient for discussions within and across the profession.

Due to the pandemic, the working group meetings will generally continue to take place online. The meetings are supplemented by guided tours of climate-relevant projects.
