In a recent announcement, the German Sustainable Building Council (DGNB) has put forth a series of recommendations for creating more eco-friendly buildings. These measures, aimed at reducing carbon footprint and promoting energy efficiency, cover various aspects of construction and design.

One of the key suggestions is the implementation of facade and roof greening. This involves the use of plants and vegetation on the building's exterior, not only enhancing its aesthetic appeal but also contributing to air purification and temperature regulation.

The Council also recommends the use of lightweight materials on roofs and facades. These materials can help reduce the building's overall weight, making it more sustainable and easier to maintain.

Thoughtful window area dimensioning and the installation of sun protection glazing are also suggested. This can help control the amount of sunlight entering the building, reducing heat gain and energy consumption for cooling.

Sensible spatial layout, use of shading systems on facades or windows, and the advantages of external and internal shading systems with light materials are also highlighted. External sun protection like blinds, awnings, and canopies are preferred, as they provide effective shade and can be easily adjusted.

Internal sun protection, if used, should be with white or light materials to reflect sunlight and reduce heat absorption.

Roof greening is another potential measure, as it can help with rainwater management and temperature regulation. Natural rainwater management systems are also being considered, which can help reduce the strain on municipal water systems.

The Council is also proposing an increase in green volume, suggesting the inclusion of more plants and vegetation in and around buildings. Water bodies are being considered as a measure, as they can help with temperature regulation and provide a tranquil environment.

Thermal insulation is being proposed to reduce heat loss in winter and heat gain in summer, making the buildings more energy-efficient.

In addition to these measures, the Council is proposing a house and property checklist to ensure that all sustainable measures are considered during the construction and design process. Partial unsealing of the property is also a possible measure, allowing for natural ventilation and temperature regulation.

These recommendations, if implemented, could lead to a significant reduction in the carbon footprint of buildings in Germany and contribute to a more sustainable future.
