Emirate-Wide Strategic Governance: Abu Dhabi

The Foundational DSM Roadmap & Portfolio Assessment | Legacy Engagement (2009–2010)

As the Lead Consultant of a German ESCO for the Demand-Side Management (DSM) module within an emirate-wide energy transformation project for ADWEA (today Department of Energy – DoE), Winfried Haas established the strategic baseline for Abu Dhabi’s building efficiency.

Facts:

  • Scale: 30,000+ buildings evaluated,
  • Impact: ~35% efficiency potential identified.
  • Priorisation: 200+ buildings prioritized

Selected European Projects: Technical Depth & Asset Rigor

The following projects reflect the founder’s track record in managing energy transitions for high-value real estate. While the Abu Dhabi legacy defined the strategy, these engagements prove the technical rigor required to optimize complex 5-star hospitality and institutional assets.
