Scaling Drivers & Barriers
- Energy efficiency policies:
- Government policies providing a clear regulatory framework encouraging energy-efficient construction and renovation can drive more sustainable building practices.
- Cost saving potential:
- High energy costs incentivize public and private building owners to invest in energy-efficient renovations and constructions, leading to reduced operational costs.
- Improved building materials:
- New materials, technologies, and processes, such as prefabricated elements, can lower the time and cost required for construction, facilitating large-scale energy-efficient projects.
- High upfront cost:
- Initial expenses for energy-efficient renovation and construction can be high, further increased by shortages of qualified personnel or certain building materials, hindering large-scale projects.
- Long payback periods:
- The lengthy payback periods of energy-efficient building projects can deter investment. A vibrant real estate market can help offset extra costs due to environmental performance or other incentive strategies.
- Regulatory barriers:
- Strict rules for renovating public buildings can make energy-efficient renovations complex and costly or even prevent these projects from being realized.
- Mindset:
- 3D planning is not standard for urban planners, architects, and building owners. Additionally, there is a shortage of manufacturers for new materials and technologies (e.g., only two manufacturers of prefabricated elements in the Munich area).
