Project Description

Market development, market segment project developers in new residential construction and general contractors

Project development in new residential construction is at the heart of the energy transition. Today, new housing developments must not only create affordable and attractive living space, but also ensure a climate-neutral energy and heat supply . Developers, cities and investors are demanding integrated solutions that combine sustainability, cost-effectiveness and digital infrastructure.

As complexity increases, so do the requirements: Project developers must integrate energy, heating and digitalization concepts into neighbourhood planning at an early stage. Successful projects are created where residential construction, local heating, photovoltaics, storage and smart control are planned and implemented from a single source.

Here are the specific challenges:

  • Integration of renewable heat and power supply (cold local heating, PV, battery storage, large heat pumps) into neighborhood planning.

  • Coordination with local authorities, municipal utilities and investors – with often heterogeneous interests.

  • Economically securing the energy infrastructure despite high construction and financing costs.

  • Compliance with legal requirements (GEG, Heat Planning Act, building regulations) and use of subsidies.

  • Consideration of new technologies: smart grid, IoT and sector coupling (electricity, heat, e-mobility) through to broadband networks and fiber optic technologies.

Developments and trends

  • Legal pressure: The Building Energy Act requires 65 % renewable energies in new buildings; many federal states stipulate PV obligations.

  • Social pressure: Tenants and buyers expect a sustainable, future-proof and affordable energy supply.
  • Economic pressure: High construction costs require subsidy integration and innovative financing models for energy projects.

  • Technological trends: Cold local heating networks (5th generation), waste heat utilization, tenant electricity models, smart district storage and digital control.

  • Funding landscape: Attractive programs from KfW, BAFA and the federal states for new-build heating networks, storage and PV obligations.

  • Best practices: Successful districts such as Bahnstadt Heidelberg (100% renewable heat), wastewater heat utilization in Stuttgart or tenant electricity districts with PV and storage show how energy infrastructure increases value and attractiveness.
