01 — CONTEXT & INVESTMENT CHALLENGE
From a Large Building Portfolio to Actionable Investment Priorities.
In 2009, the Abu Dhabi Water and Electricity Authority (ADWEA), today part of Department of Energy (DoE), commissioned the assignment Consultancy Services for DSM Implementation & Expansion to assess Demand-Side Management opportunities across the Emirate.
The challenge extended beyond identifying energy-efficiency potential. A portfolio of more than 30,000 buildings had to be translated into a structured basis for identifying priority assets, investigating Efficiency Retrofit opportunities and directing further technical and investment analysis.
02 — TECHNICAL ASSESSMENT SCOPE
Identifying Where Efficiency Retrofit Could Create Material Impact.
The assessment screened the building portfolio to identify energy-intensive building types and prioritise assets for further investigation.
More than 200 buildings were selected for detailed assessment, including energy measurements and audits of major energy-consuming systems such as cooling, HVAC, lighting and controls. Depending on asset type, existing systems and operating conditions, savings potential of up to approximately 35% was identified in selected buildings.
03 — ASSESSMENT APPROACH
Translating Technical Potential into Comparable Investment Cases.
A portfolio methodology was developed to move systematically from emirate-wide screening to priority assets and specific Efficiency Retrofit opportunities.
Technical measures were translated into alternative investment packages and evaluated across CAPEX, OPEX, energy savings, payback and investment returns, supported by sensitivity analysis.
This enabled different combinations of measures to be compared according to capital requirements, expected financial performance and achievable energy-efficiency improvements — creating a structured basis for prioritisation and further investment decisions.
04 — RECOMMENDATIONS & OUTCOME
Establishing a Basis for Large-Scale DSM Investment.
The engagement established a structured approach for identifying and evaluating energy-efficiency opportunities across a highly diverse building portfolio, narrowing more than 30,000 buildings to priority assets requiring deeper investigation.
Several years later, Energy Performance Contracting structures were implemented for pilot buildings associated with Abu Dhabi’s wider DSM programme. The Department of Energy subsequently reported initial average verified energy savings of 38% across eight government buildings.
The original advisory team did not deliver, guarantee or participate in these later contracts. The subsequent results therefore provide wider programme context rather than performance attributable to the 2009–2010 engagement.
05 — ROLE OF WINFRIED HAAS
Leading the DSM Assessment from Portfolio Strategy to Investment Analysis.
Winfried Haas served as Lead Consultant for the building efficiency component of Abu Dhabi’s emirate-wide Demand-Side Management programme for ADWEA (now under the DoE), representing a leading German energy services group.
Working in Abu Dhabi with an international engineering team, he led the strategic portfolio assessment and development of the methodology for identifying, evaluating and prioritising energy-efficiency opportunities.
His responsibility connected portfolio strategy and technical assessment with investment analysis, including the evaluation of CAPEX, OPEX, energy savings, payback, investment returns and sensitivities.
06 — RELEVANCE FOR OWNERS TODAY
Portfolio Potential Must Be Translated into Investment Priorities.
Large portfolios may contain substantial energy-efficiency potential, but owners still need to determine where deeper investigation and capital deployment can create the strongest investment case.
