OWNER-SIDE REAL ESTATE ADVISORY
Find the best way to Decarbonise your Buildings - Invest with Confidence.
We help real estate owners identify, develop and evaluate Net Zero Investment Pathways for existing buildings — challenging critical assumptions, comparing alternatives and bringing technical and economic evidence together to support confident investment decisions.
INVESTMENT DECISION CONFIDENCE
From fragmented specialist inputs to one coherent owner-side investment view
✓ Which Net Zero Investment Pathways are technically and economically viable
✓ Which critical assumptions are valid — and which need to be challenged
✓ How alternative pathways compare on CAPEX, OPEX, lifecycle economics and risk
✓ Which pathways credibly support your Net Zero objectives
The decision gap
Different Disciplines Produce Different Answers. Ownership Needs One Coherent Investment View.
Energy audits, engineering studies, ESG strategies, contractor proposals and financial models are often developed by different parties, using different assumptions.
Each addresses a specific aspect of building decarbonisation. But owners must bring these perspectives together to determine which Net Zero Investment Pathway best serves their asset and investment objectives.
The Solution Perspective
“Which technical solution can achieve the required performance?”
The Ownership Perspective
“Which Investment Pathway best meets the owner’s objectives?”
Net Zero Investment Pathway
Compare Pathways Before Choosing the Solution.
The best Net Zero investment is rarely about one technology. It comes from finding the right balance between reducing energy demand, rethinking energy systems and decarbonising energy supply.
HAAS Perspective identifies, develops and evaluates alternative Net Zero Investment Pathways across three interconnected dimensions:
REDUCE - Demand
How far should energy demand be reduced to achieve the best lifecycle economics?
RETHINK - System
Could alternative energy-system architectures deliver better long-term performance and economics?
RE-SOURCE - Supply
How can the remaining energy demand be met through renewable and low-carbon energy sources?
The Owner defines the Objective. The Asset and the Economics define the Pathway.
