Work Package #5

The first chapter of this deliverable presents the results of a thorough assessment regarding the influence of VGS integration on the microclimate and buildings’ energy efficiency. Different real case scenarios are designed, based on the specific conditions of urban district in Thessaloniki, related to thermal island effects. In addition, the Greenergy Guidelines provide a comprehensive framework for transforming new or existing buildings into vertical forest structures. They combine knowledge from structural engineering, architecture, and urban forestry to ensure that buildings maintain structural integrity, energy efficiency, human comfort, aesthetic harmony, and ecological value. By linking these disciplines, the guidelines aim to help professionals design and construct buildings that meet technical and architectural standards while improving environmental quality and urban resilience through the integration of vegetation. The Greenergy Guidelines provide a comprehensive framework for the renovation of existing buildings into structures incorporating vertical forest. They highlight the ecological, functional, and aesthetic advantages of incorporating greenery into buildings, promoting healthier living and working environments. It covers a range of systems, from simple green solutions to complex vertical forest designs, addressing key aspects such as construction methods, materials, and plant selection. The guidelines outline essential principles for the design, retrofitting, planning, implementation, and monitoring of vertical forest systems, offering practical direction based on current knowledge and best practices. The main focus is on structural, forestry, energy and comfort engineering, supported by

complementary design and construction guidance and is intended for professionals working across related fields. It introduces disaster risk management and society awareness, involving all involved stakeholders.
