Net Zero baselines & pathways
Establish defensible energy and emissions baselines and build technically credible reduction pathways.
Net Zero Strategy & Investment
Net Zero ambition.
Investable delivery.
Turn long-term carbon objectives into an evidence-based, costed and deliverable programme. Reduce demand, test the options and invest where it matters.
Independent engineering judgement. Practical carbon reduction. Investment clarity.

The Net Zero delivery gap
Targets are common.
Investable plans are not.
Many Net Zero strategies set an ambition but fail to connect it to building condition, operational requirements, capital constraints and the people who must deliver the work.
A target without a credible delivery programme remains an aspiration.
01
Weak baselinesInconsistent energy, carbon and asset evidence.
02
Technology-first thinkingSolutions selected before demand is understood.
03
Uncosted ambitionProjects lacking credible investment cases.
04
Poor sequencingDependencies between fabric, plant and power overlooked.

The Zerith approach
Use less. Improve what exists.
Replace intelligently.
Explore the six engineering-led stages that connect current building performance to a phased and measurable Net Zero programme.
STAGE 01 / 06
Establish the baseline
Build a clear picture of energy, emissions, assets and the demands they serve.
Our capabilities
From baseline to an investable transition programme.
The right decarbonisation pathway combines operational understanding, credible modelling, practical technology choices and realistic delivery support.
Energy & building modelling
Assess operational demand, fabric, comfort and system scenarios, including IES Virtual Environment modelling where appropriate.
Building & process decarbonisation
Target avoidable energy use and improve controls, HVAC, plant and processes before major replacements.
Heat decarbonisation
Assess heat pumps, heat networks, low-carbon sources and distribution compatibility.
Renewables & storage
Evaluate solar PV, battery storage, supply arrangements and grid integration against demand profiles.
Power & transport electrification
Review electrical capacity, fleet transition and EV infrastructure with resilience and operational needs in mind.
Investment & programme planning
Compare capital costs, carbon benefits, lifecycle value, constraints and delivery risks.
Implementation & verification
Connect business cases to design, procurement, commissioning and measured outcomes.
Invest with evidence
Carbon impact matters.
So does deliverability.
A lower-carbon solution is not always the next practical investment. Every opportunity must be judged against technical feasibility, commercial value, timing and operational risk.

ZECO-enabled intelligence
Make Net Zero progress visible.
ZECO can structure energy and carbon baselines, support opportunity registers and scenario comparison, and make delivery progress easier to communicate across portfolios.
It supports the evidence. Zerith’s engineers provide the technical assessment, judgement and delivery recommendations.

Relevant engineering experience
Experience beyond strategy documents.
Selected examples described in Zerith’s published Net Zero material demonstrate expertise spanning energy centres, low-carbon infrastructure and the transition to electrified transport.
Net Zero student accommodation energy centre
Engineering and project-management experience on a central energy centre integrating combined heat and power with renewable biomass and coordinated operation.
Low-carbon energy centre strategy
An energy-centre strategy for a custodial expansion, described in Zerith’s published material as delivering approximately 60% lower carbon emissions against its project baseline.
Electric vehicle infrastructure and market entry
Technical due diligence and transition planning connecting vehicle deployment to manufacturing, renewable-energy and charging infrastructure.
High-capacity Net Zero charging concept
Concept-stage support for multiple simultaneous 350 kW chargers, balancing on-site generation, dispatchable energy and site resilience.
These are published experience examples; project outcomes, scopes and baselines depend on the individual project. No general savings guarantee is implied.
Frequently asked questions
Clear answers. Practical next steps.
Get clarity on scope, investment, engineering dependencies and how the pathway is taken into delivery.
What should a credible Net Zero strategy include?
A reliable energy and carbon baseline, practical opportunities to reduce demand, technically tested decarbonisation options, capital and lifecycle implications, delivery responsibilities and a phased programme with measurable milestones.
How much does a Net Zero roadmap cost?
The scope depends on the size and complexity of the estate, the condition of available information, and the modelling and engineering detail required. Zerith can define a proportionate scope after an initial discussion.
Can you support an existing sustainability or estates team?
Yes. Zerith can work alongside in-house energy, estates, finance and sustainability leads to supply engineering evidence, investment analysis and delivery assurance.
Do we need to replace gas boilers immediately?
Not necessarily. A credible heat transition considers remaining asset life, existing heat demand, operating temperatures, electric capacity, efficiency improvements and the timing of other estate works before selecting solutions.
Can ZECO replace engineering surveys or modelling?
No. ZECO supports organising and comparing energy and carbon information, opportunities and progress. Engineers still need to review building systems, assumptions, feasibility and investment recommendations.
How is progress verified?
Use appropriate baselines and monitoring, with adjustments where relevant for weather, occupancy, production or operational changes. The method is agreed to suit each measure and available data.
