Clean Energy & Engineering Achievements
A showcase of key projects I have led, engineered, and optimised. Classified by my direct individual leadership and strategic team management.
Major Project • Individual Lead
Baumschulenweg Crematory Modernisation, Berlin
Led the complete technical energy modernisation of the facility, utilising process waste heat recovery for absorption chilling integrated with a direct district heating grid connection to eliminate the local boiler.
STAR Case Study:
Situation: Outdated energy systems inside the architecturally protected landmark building resulted in high operational costs. The technical goal was to increase the energy efficiency in the crematorium, reducing CO2 emissions.
Task: Direct the complete end-to-end engineering modernisation, building automation overhaul, and subsidy administration as the primary Project Manager.
Action:
- Thermal Engineering: Integrated process waste heat recovery with a new absorption chiller (backed by a redundant compression chiller) and established a direct connection to the local district heating grid, cutting out the local boiler entirely and enabling excess heat feedback.
- Systems Renovation: Upgraded the HVAC systems, Instrumentation & Control (I&C), and cremation lighting.
- Subsidy & Bureaucracy Management: Acted as the primary pragmatic contact for public funding bodies; compiled all reports and structured planning documentation ("Bauplanungsunterlagen") according to Berlin's public building guidelines (ABau), keeping the Senate and funding stakeholders in the loop regarding claims and variations.
- Tendering & Lifecycle Management: Managed the entire public bidding, contracting, and tendering lifecycle under German construction contracting (VOB) guidelines.
Result: Delivered a highly optimised heating/cooling system to achieve major CO2 emission reductions and energy savings. Successfully handed over the operational plant to the client.
Major Project • Individual Lead
Ruhleben Crematory Modernisation, Berlin
Replicated Baumschulenweg's waste-heat-to-cooling modernisation at the Ruhleben facility, but engineered thermal storage arrays and a backup auxiliary boiler due to the lack of a local district heating grid connection.
STAR Case Study:
Situation: Outdated energy structures inside the Ruhleben crematory faced high energy losses, and a local grid connection to district heating was unavailable, requiring a different energy buffering design.
Task: Oversee the complete engineering modernisation and subsidy administration as Project Manager, resolving the lack of local district heating through custom thermal storage.
Action:
- Thermal Engineering: Integrated process waste heat recovery with a new absorption chiller (backed by a redundant compression chiller) integrated with a custom auxiliary backup boiler and expanded thermal heating storage arrays to buffer energy during operational gaps.
- Systems Renovation: Upgraded the HVAC systems, Instrumentation & Control (I&C), and cremation lighting.
- Subsidy & Bureaucracy Management: Acted as the primary pragmatic contact for public funding bodies; compiled all reports and structured planning documentation ("Bauplanungsunterlagen") according to Berlin's public building guidelines (ABau), keeping the Senate and funding stakeholders in the loop regarding claims and variations.
- Tendering & Lifecycle Management: Managed the entire public bidding, contracting, and tendering lifecycle under German construction contracting (VOB) guidelines.
Result: Delivered a highly optimised heating/cooling system to achieve major CO2 emission reductions and energy savings. Successfully handed over the operational plant to the client.
Team Leadership • Advisory
Quartier Buckower Felder, Berlin
Fostering team execution for an innovative, fossil-free residential quarter, providing senior leadership support and conflict resolution.
Key Contributions & Scope:
- Team Empowerment: Provided strategic direction and technical guidance to team members executing this complex project.
- Executive Oversight: Stepped in to resolve coordination conflicts and supported negotiations.
- Autonomous Progress: Enabled self-organised project engineering by establishing collaborative workflows and standards.
Team Leadership • Advisory
Quartier Haus der Statistik, Berlin
Supporting the technical project team deploying a multi-source renewable heating and cooling network in central Berlin.
Key Contributions & Scope:
- Strategic Advisory Support: Supported the direct project managers, offering technical advice.
- Decision Authority: Facilitated critical executive decisions.
Major Project • Individual Lead
Rollberg Quarter, Berlin
Executing a circular local heating and cooling grid utilising solar thermal collectors, three heat pumps with distinct thermal sources (HVAC exhaust air, ambient air, and underground seasonal storage), a CHP unit, and a peak-load boiler.
STAR Case Study:
Situation: An ambitious residential district development in Berlin required a local clean energy heating and cooling grid with high circular efficiency, constrained by strict public tendering guidelines and complex technical system integration.
Task: Direct the entire engineering implementation, subsidy administration, contract management, and system integration as the individual Project Manager—leading the project independently from contract signing through execution to final operational handover.
Action:
- Multi-Source Heat Pump Design: Engineered a multi-source heat pump array utilising three distinct energy sources: building exhaust air flows via an HVAC heat pump, ambient outdoor air via a reversible heat pump (providing active cooling in summer), and a brine-to-water heat pump connected to seasonal underground thermal storage.
- Solar & Cogeneration Integration: Connected solar thermal collectors to feed the seasonal storage and integrated a Combined Heat and Power (CHP) unit for simultaneous power and heat generation, backed by a conventional gas boiler for peak-load demands.
- Lifecycle Management: Developed and negotiated the contract and managed contract variations.
Result: Successfully managed the complete lifecycle from contract to operational handover, achieving a carbon-reduced energy supply system, cooperating with operations for ongoing optimisations.
Major Project • Co-Lead
Friesenstraße Police Headquarters
Co-managed the entire engineering implementation and centralization of the heating system for the secure, operational police headquarters.
STAR Case Study:
Situation: Legacy heating and distribution systems within the large police headquarters complex led to recurring operational interruptions.
Task: Actively co-manage the complete design, centralised implementation, and system-separation modernisations to ensure full resilience and eliminate site-wide heating failures.
Action:
- Technical Division: Led the structural design and on-site construction of the new centralised main heating plant, while supporting my co-lead in the planning and implementation of the distribution network upgrades and decentralised heating substation renewals, including system separation.
- Operational Logistics: As an example, I coordinated closely with the client to align major trenching and pipeline works with the police’s 24/7 emergency response operations, ensuring uninterrupted deployment capability while enabling the phased opening of streets for the distribution network installation.
- Stakeholder Alignment: Chaired all primary communications with the public client and supervised shared supplier contractors under German construction contract procedures (VOB/B) parameters.
Result: Delivered a fully modernised centralised heating grid with complete building-level system separation, preventing building-wide heat failures while ensuring a high level of operational reliability and security.
