Energy consulting and EnEV assessments

Efficient energy use is a key principle of sustainability, but also of economic viability. That is why our engineering firm complements its range of services with expert assessment work. We are recognized as EnEV-certified experts and provide building owners with impartial and effective advice. We also inspect and evaluate our business partners’ existing buildings—for example with regard to their energy consumption—and prepare assessments in accordance with the Energy Saving Ordinance (EnEV). We are licensed for both residential and non-residential buildings.

As EnEV experts certified by the Bavarian Chamber of Engineers (Ingenieurekammer Bau), we provide you with comprehensive and professional energy consulting services:

  • Using energy more efficiently
  • Impartial advice
  • Heating system diagnostics
  • Energy-saving check and energy performance certificate
  • U-value calculation

Energy management

Ingenieurbüro Brundobler develops comprehensive energy efficiency and funding concepts tailored to each client’s individual needs, ensuring maximum cost-effectiveness.

  • Consulting and planning for efficient energy solutions
  • Consulting and planning for the use of funding programs
  • Integrating renewable energy into existing systems
  • Optimizing energy consumption and reducing operating costs

Facility management

When operating larger buildings and facilities, a wide range of services is required. For cost reasons, these services are increasingly outsourced to external companies. We provide many of these services in-house, but we are also a sought-after specialist when it comes to tendering processes. The expertise of our staff ensures tender documents that form the foundation for successful collaboration between client and service provider.

We provide engineering services in the area of managing buildings, facilities, and equipment as technical services, including:

  • Modernization and optimization
  • Energy management
  • Provision of utilities and services
  • Operation and maintenance
