Generation of comparable measurement data for impact assessment of green facades and roofs for the building and the adjacent urban space
Abstract
The HEDWIG project aims to determine the effects of standard-compliant building greenery (green roofs and facades) in the course of permanent monitoring. Sound and resilient vegetation parameters and performance parameters will be obtained and related to the effects of building greening on the indoor and exterior microclimate. HEDWIG develops and verifies a measurement setup suitable for the collection of valid data, their comparability and the evaluation of Green Infrastructure demonstration projects. HEDWIG collects microclimatic and building physical data from 15 representative green buildings with heterogeneous age structures and different types of use. Measurement campaigns and continuous measurements will be applied over two years. Parameters such as transmissivity of climbing plants, heat flux through green roof structures or indoor thermal comfort are recorded in a structured and standardised way. This allows for developing standard parameters for green infrastructure typologies and transfer them to planning and implementation processes. The measurements are supplemented and supported by thermal building simulations. A data evaluation procedure will be developed and standardised to enable cross-site comparisons. Periodically occurring effects as well as favourable and disruptive influencing factors will be identified and made calculable. New findings are in particular expected on the microclimatic influence of green bodies on the building envelope and the interior. An optional objective is assessment of microclimatic effects for the adjacent street space and urban area. The HEDWIG measurement and analysis methodology will be documented in a comprehensible way and made available as open content for future research and demonstration projects. The findings from the key values and effects should enable the further development of calculation models, promote the further mainstreaming of green buildings and form the basis for argumentation and approval processes.
