Environmental performance of green building systems

ADI conducted parameterized life‑cycle assessments of major green building assessment systems using hybrid life‑cycle inventory methods and EPA TRACI impact categories. The analysis explicitly modeled construction materials, energy use, and system boundaries to compare LEED, ASHRAE, and IgCC pathways against a baseline commercial building. Sensitivity and uncertainty analyses were used to isolate which building features most strongly influence environmental outcomes.

The situation

Policymakers lacked consistent, quantitative evidence on how green building standards translate into environmental performance.

ADI’s contributions

Contribution icon 1

Hybrid lifecycle modeling

Applied hybrid LCI methods to capture both process‑level and economy‑wide impacts.

Contribution icon 2

Standards comparison

Modeled LEED, ASHRAE, and IgCC requirements against a common reference building.

Contribution icon 3

Sensitivity analysis

Tested uncertainty in materials, energy use, and system boundaries to identify dominant drivers.

Contribution icon 4

Policy‑relevant reporting

Translated technical LCA results into insights usable for standards development and regulation.

Key outcomes

  • Provided a defensible basis to compare green building systems and identify features with the largest lifecycle impact.
Client Results
ADI helped us quantify our target market size in a very methodical manner. They got up to speed very quickly on what we do, spending time with our team, technology, and markets to perform a thorough evaluation themselves.

Industry experience

Sustainability assessment for electric utilities

ADI assessed how sustainability priorities are influencing actual capital allocation across electric utilities, with a focus on transmission, distribution, and grid digitalization. The work drew on utility‑level benchmarks covering decarbonization targets, resilience investments, and governance structures, supplemented by interviews with sustainability and planning leaders. Emphasis was placed on distinguishing aspirational ESG commitments from areas driving […]

Lifecycle economics of engineered geothermal systems

ADI independently assessed engineered geothermal system economics using expert elicitation and lifecycle cost modeling. Drilling depth, well productivity, stimulation costs, and surface plant design were treated explicitly to capture uncertainty ranges in LCOE outcomes. Results highlighted where cost reduction efforts would have the greatest impact on commercial viability. The client U.S. Department of Energy The […]

Building efficiency assessment methodology

ADI developed a vendor‑independent Building Efficiency Assessment Methodology (BEAM) to quantify energy savings, emissions reductions, and retrofit economics across existing building portfolios. The work combined inductive benchmarking from comparable buildings, scenario‑based modeling, and conversion‑rate analysis to move retrofit decisions upstream without costly on‑site audits. Emphasis was placed on translating engineering outputs into CFO‑relevant metrics such […]

Energy transition strategy for offshore services

ADI screened over 20 energy transition opportunities to identify growth areas that leverage the client’s existing subsea engineering and offshore logistics capabilities. Opportunity profiling included a deep dive into the fixed and floating offshore wind segments, specifically targeting substructures and dynamic cable systems. The client Offshore engineering provider The situation Client needed to diversify into […]

Global energy transition digital spend outlook

ADI assessed a global energy transition capital spend and outlook through 2050, identifying the addressable market for digital technologies. The study analyzed how the shift toward fragmented, low-carbon infrastructure will impact the need for digital integration across intermittent renewables and energy storage systems. Modeling surfaced critical factors that will dictate the pace of digital adoption. […]

EU methane rule delay: A tactical retreat or climate setback?

The European Union (EU) Methane Regulation is known for its strict methane emissions transparency requirements for foreign oil and gas imports, and has driven methane emissions monitoring and reporting efforts, especially among oil and gas players serving the EU market. Under Article 28 of the EU Methane Regulation, importers are required to demonstrate that fossil […]

Notes from the Gas to Grid Summit

Gas-to-grid infrastructure has received limited attention amid rapid growth in data-center power demand. Pipelines, storage, fuel delivery, generation, and grid connections determine when new load can receive reliable power.  ADI Analytics and Energy Conference Network launched the inaugural Gas to Grid Summit to examine this part of the value chain. Participants included midstream operators Williams […]

Post-auto growth in lubricants

HF Sinclair plans to separate its Lubricants & Specialties business, retire its 15,600-barrel-per-day Ontario base oil refinery, and replace internal production with long-term supply agreements. Similar portfolio activity is visible across the industry: BP sold a controlling interest in Castrol, Saudi Aramco acquired Valvoline’s global products business, and private-equity-backed distributors continue to add local businesses.
