Doctoral Session - ERES Conference - June 2009

• What certificate can provide which benefits?• Which opportunities and which risks are associated with obtaining a
certificate? • Is it just a new name for the same old product?
► Research into the economy of construction and occupancy of certified properties.

Existing Precedents
• Overview of several tools on the German market analyzing their framework, structure and criteria> DGNB most comprehensive
• First opinion surveys among developers, owners and tenants> Growing interest
• Comparing costs and benefits of certified and conventional buildings
(for example US: LEED)> It’s worth investing
‣ Need of Further Research
• Find out the needs of developers, owners and tenants in detail
• Compare these needs to the Benefit of International Standards as well as with existing German standards and lawsB
