The zero-carbon roadmap

At the heart of our operations is the unique zero-carbon roadmap.

This is an innovative pathway of logical steps we’ve developed, that leads to the sharp reduction or abolition of net emissions from clients’ new and existing buildings, during both construction or refurbishment and operation.

But the roadmap’s benefits go way beyond cutting carbon. Indeed, the advantages we provide are so numerous we’ve grouped the main ones under headings we call our four Cs:

Hugely lowered or abolished carbon emissions, both embodied and operational

Substantial cost savings in both capital and ongoing spending

Massively enhanced comfort for building occupants

Superior Credentials: improved on-site energy and carbon reporting and improved ratings such as WELL, EPCs and BREEAM

How the roadmap pays off

Here's an example of the impact we can make.

Applying the roadmap’s elements has delivered benefits at a new company headquarters, compared to its base building concept, including a:


reduction in annual energy usage


cut in yearly carbon emissions


slashing of annual running cost


saving in capital spending


lowering of capital outlay on roof-based solar panels needed to achieve net zero carbon emissions

Lower carbon by design

Low carbon starts with the building fabric.

We can help you see the impact of your design decisions on the carbon emissions of your building by testing them in a virtual prototype. We help achieve true sustainability by balancing human comfort, energy, and cost –  iteratively testing many different options.

Real Social Value

Enhanced occupant comfort and wellbeing.

By following our zero carbon road map all the following benefits are provided for indoor environments which lead to improved staff loyalty, absenteeism, and productivity, for example:

Healthy access to daylight – our recommendations can make huge positive differences here

Improved ventilation providing lower concentrations of carbon dioxide, volatile organic compounds, and other pollutants

Reduced temperature ranges, which staff can control

Low noise and better acoustics

Reduce Costs

Reduced carbon emission means lower costs.

We provide demonstrably better solutions to our clients. You can be confident that we can help deliver the best value for any investment. It’s not just a cheaper solution. We have a track record of delivering truly value engineered solutions for our clients that improve human comfort, improve sustainability and save money; both CAPEX and OPEX.

Reduce costs

ESG (Environmental, Social and Governance).

How the Zero Carbon Roadmap helps.

More appealing to building users

Greater access to obtain funding

Positive reactions from building users and shareholders

Improved value of property assets

Enhanced selling appeal of property

More attractive to prospective tenants

Enhanced company brand

Zero Carbon Roadmap

Let us help you develop a zero carbon roadmap for your building, following our tried and tested methodology we will improve your internal environment, reduce energy, reduce carbon and running cost whilst saving capital cost.

Our Approach

Our distinctive and unique iterative process is the key

Our philosophy, knowledge, technology, methods and experience made us supremely well-placed to develop a coherent zero-carbon road map.

This sets out a logical series of practical steps leading ultimately to net zero emissions, involving speedily and directly comparing each realistic option for a particular function with all the alternatives in depth, to clearly identify the best solution.

The roadmap doesn’t just benefit new buildings…it’s equally applicable to existing constructions.

Nor is it just about eliminating net emissions, as it delivers massive reductions for premises where complete abolition isn’t currently feasible.

And the roadmap delivers a wide range of other valuable benefits, in addition to cutting carbon.

How does the Zero-carbon roadmap work?

Our zero-carbon roadmap shows helping the planet needn’t cost the earth.

Reducing operational carbon.

  • Set targets

  • Construction methodologies
  • Work with supply chains - Certification

Public Disclosure

  • Detailed Design LCA
  • As Built LCA
  • Third Party Verification

Reducing operational carbon.

We do this via a passive design first approach which minimised embodied carbon and promotes a zero-carbon balance. A passive design approach reduces the inherent energy demand first, this not only achieve lower carbon emissions but is the basis for achieving this at the lowest CAPEX, but taking things away rather than adding to overcome an energy-intensive building.

  • Setting energy usage intensity targets

  • Developing zero-carbon specifications

  • Maximising the use of daylight

  • Optimising passive design

  • Designing relevant systems and controls

When should you contact us?

At the outset of any new build or refurbishment project.

We do much more than merely validate existing plans, as we add significant value at all four building stages:

Master planning and concept




So, the earlier you involve us in your project, the more you’re likely to benefit.

Typical Services

Operational Energy & Carbon Calculations

A detailed, robust and reliable assessment of a building's annual energy consumption and carbon emissions. Real-world data, such as actual operating hours, projected occupancy levels & schedules, actual equipment power, projected Domestic Hot Water consumption and accurate Heating, Ventilation & Air Conditioning. modelling, this analysis provides macroscale data. It also assesses finer details such as peak consumption periods or cogeneration capabilities of LZC technologies. The analysis can provide an effective baseline for integration to building monitoring systems and can inform users of realistic energy consumption targets.

Embodied Carbon and Life Cycle Assessments

The carbon footprint of the building. Considers how many greenhouse gases (GHGs) are released from cradle to grave. The Embodied Carbon includes the extraction of materials from the ground, transport, refining, processing, assembly, in-use (of the product) and finally its end-of-life profile.
