A Step-by-Step Guide to Reducing Your Carbon Footprint: The EM3 Customer Journey
As an energy management solutions provider, EM3 understands the complexities involved when organisations wish to progress along the path to decarbonisation. In this blog, we’ll set out our step-by-step approach to reducing your carbon footprint and achieving your sustainability goals.
- The Audit: Uncovering Opportunities
The first step in this journey is the energy audit. While some organisations may have already had an audit, perhaps conducted by their utility company, EM3 takes a deeper, more thorough approach. Over the course of 1-3 days on site, our team conducts a comprehensive energy and water assessment, usually uncovering a wealth of opportunities for improvement. - From Opportunity List to Decarbonisation Strategy: Mapping Your Path Forward
The energy audit culminates in the creation of an Opportunity List – a detailed inventory of potential energy-saving and carbon reduction measures. These range from simple ‘low cost or no cost’ housekeeping tasks, like lowering setpoints and optimising operation, to far more complex energy efficiency projects and renewable energy investments.The key here is determining where to focus your efforts. By analysing the potential savings, investment costs and carbon impact of each opportunity, you can prioritise the initiatives that will deliver the greatest return on investment and the most substantial carbon reductions. We can also support with tendering and draw down of grants to support the project.
To support this critical decision-making process, EM3 works closely with you to develop a customised decarbonisation strategy. This involves carefully evaluating the ‘yeses’ and ‘nos’ – the initiatives that are worth pursuing and those that may not align with your goals or available budget.
To facilitate this decision-making process, EM3 has developed an in-house Carbon Efficiency Tool. This quick-fire tool allows us to perform detailed, tailored calculations, providing you with a clear understanding of the financial and environmental impacts of various decarbonisation strategies.
- Feasibility Studies and Conceptual Design
With the decarbonisation strategy in place, the next step is to dive deeper into the feasibility and conceptual design of the selected opportunities. This initial phase is critical for evaluating multiple options and determining which path forward offers the best combination of cost-effectiveness, carbon reduction and operational fit.Understanding Different Terminologies
Different organisations use different terminology for this phase of the journey. You might know it as a Feasibility Study, Concept Design, FEED (Front-End Engineering Design) or an ASHRAE Level 1 Energy Audit. Some clients refer to it by internal codes like DR1 (Design Readiness 1) or TG1 (Technical Gate 1). At EM3, we understand that what matters isn’t what you call it – it’s ensuring we align with your organisation’s established processes and approval structures.The Feasibility Phase: Exploring Your Options
During the feasibility assessment, the EM3 team evaluates multiple pathways to achieve your goals – typically examining six or seven different approaches to the same challenge. Using high-level calculations, we can quickly identify which solutions offer the most promising payback periods and carbon reductions, allowing you to make informed decisions about where to focus your investment.The Conceptual Design: Adding Depth and Confidence
Once a preferred direction emerges, we move into the conceptual design phase. EM3 has commonly referred to this as ‘BOD A’ – Basis of Design ‘A’. Other organisations may call it a Concept Design or a Level 1 Audit. Here, we add substantially more detail to validate those initial numbers, refine equipment sizing and placement, and ensure proposed solutions align with your operational requirements. While estimates at this stage typically carry a +/- 30% accuracy range, you’ll have sufficient confidence to secure internal approvals and move forward.Time Well Invested
Many organisations are tempted to ‘skip’ the feasibility stage and jump straight to detailed design. However, experience shows that this early investment (typically around 1 month for feasibility and 1-2 months for conceptual design) is time exceptionally well spent. When you consider that a full decarbonisation project might span 2-3 years, spending an extra few months at the start to evaluate all options properly can save months of rework later and ensures you’re pursuing the optimal solution rather than just the first viable one. Bad decisions at early stages can lead to poor CapEx investment and increased OpEx forever more. - Design Development and Tendering: Working Within Your Framework
Building on the feasibility study and conceptual design, the next phases develop your project toward implementation-ready specifications. EM3 works flexibly within your organisation’s established framework – whether you call these stages Basic Design, FEED, IFT (Issue for Tender) or use internal designation systems. Our goal is to align seamlessly with your approval processes, procurement requirements and engineering standards, not to impose our terminology on you.(i). Initial Design Phase (Concept / Basis of Design A)
Note: This stage may be called Concept Design, Energy Audit Level 2 or another internal term depending on your organisation.This stage lays the groundwork for the entire project. With a cost estimate accuracy of +/- 30-40%, the team develops a high-level schematic that captures the project’s fundamental vision. Engineers create an initial overview of equipment sizing, exploring how proposed solutions might integrate into the existing infrastructure.
(ii). Intermediate Design Phase (Basic Design / Basis of Design B)
Note: This stage may be called Basic Design, Energy Audit Level 2 or another internal term depending on your organisation.Building upon the initial concept, this stage delves deeper into technical specifics. With improved cost estimate accuracy of +/- 20%, this phase involves developing comprehensive Process and Instrumentation Diagrams (P&IDs). Engineers begin to map out precise pipeline routing, specify intricate instrumentation details and conduct preliminary equipment pricing. The schematic transforms from a rough outline to a much more detailed blueprint, showing exactly how systems such as heat pumps would integrate and function within the broader infrastructure.
When This Stage Might Be Optional: For many projects, approximately 80% in EM3’s experience, this intermediate stage can be abbreviated or skipped entirely if the Concept Design was thorough and metering systems are robust. For solutions like heat pump installations, where EM3 maintains current pricing data from regular projects, this level of detail may not add sufficient value to justify the additional time. The exception would be if you’re working with bespoke or unusual equipment that requires additional vendor engagement before committing to tender specifications.
(iii). Final Design and Tender Phase (IFT / Basis of Design C)
Note: This stage may be called IFT (Issue for Tender), pre-CapEx approval, Energy Audit Level 3 or another internal term depending on your organisation.This phase brings the project to tender-ready status. Achieving a cost estimate accuracy of +/- 10%, this step involves creating complete, detailed design packages including in-depth specifications for automation systems, electrical configurations, mechanical components, and civil and structural plans. The EM3 team generates full 3D drawings to provide superior clarity, enabling contractors to price the project with more precision.
EM3’s Flexible Approach
Throughout these stages, EM3 adapts to your organisation’s specific requirements and terminology. If you need to align your corporation’s internal engineering standards, we configure our deliverables and stage gates to match your approval processes.Some organisations require all three design phases; others benefit from a streamlined approach that focuses investment on thorough feasibility analysis followed by a more direct move towards tender documentation. Our pricing structure reflects these different pathways, ensuring you pay for the value you need rather than unnecessary process steps.
The key principle is this: invest adequate time and resources in the early stages to evaluate options thoroughly. This front-loaded approach provides the confidence which could potentially accelerate later stages, ultimately delivering a faster time-to-implementation with lower overall risk.
- Detailed Design and Implementation
Note: Some organisations combine this with the previous phase under terms like IFC (Issue for Construction). With the tendering process complete and the project approved, EM3 shifts its focus to the detailed design and implementation phases. During this stage, the team finalises the design, issues construction drawings and manages the project’s execution, ensuring that the proposed solutions are implemented effectively and efficiently. - Project Management: Keeping Your Project on Track
Project management and supervision at EM3 encompasses a comprehensive approach tailored to different project complexities. For the vast majority of projects, EM3 provides standard project management services, supporting the design process, addressing contractor queries and facilitating technical communication. The project management team serves as a critical resource, responding to contractor questions and ensuring smooth progression of the project.For more specialised bespoke projects, EM3 can also offer more intensive construction management, focusing on day-to-day coordination and detailed tracking of project activities. In Ireland, this oversight includes defined roles such as PSDP (Project Supervisor Design Phase) and PSCS (Project Supervisor Construction Phase). In the UK, similar roles are called PD (Principal Designer) and PC (Principal Contractor). The design phase supervisor takes overall responsibility for design-related aspects, managing design risk assessments and ensuring comprehensive design coordination. Meanwhile, the construction phase supervisor oversees the practical implementation, coordinating site activities and managing the construction phase’s operational details
Good project management is crucial in maintaining project safety, ensuring regulatory compliance and delivering efficient project outcomes. By providing this level of structured management, EM3 can adapt its approach to the specific needs of each project, whether it’s a straightforward implementation or a complex, multi-faceted decarbonisation initiative.
- Commissioning: Validating Performance
The next critical – and exciting – step is commissioning. During this stage, the EM3 team conducts a thorough series of system checks to ensure the newly installed equipment and systems are functioning as intended. This involves creating a detailed plan, reviewing the design, on-site installation verification, rigorous functional and performance testing, resolving issues and, finally, documenting and training for handover and ongoing operation. And then it’s Go Live! - Monitoring and Continuous Commissioning
With the initial commissioning complete, EM3 shifts its focus to ongoing monitoring and continuous commissioning. This allows us to verify that the implemented solutions are delivering the expected energy savings and carbon reductions over time.Through a process of regular inspections, data analysis and fine-tuning, the EM3 team ensures the systems continue to perform at their optimal levels. This can include conducting Factory Acceptance Tests (FATs) and Site Acceptance Tests (SATs) to validate the performance of the equipment
- Measurement and Verification
The final step in the decarbonisation journey is measurement and verification. EM3 will work closely with you to establish clear performance metrics and then monitor those metrics over an extended period, typically 12 months or more. This allows us to confirm definitively that the project is delivering the intended energy and carbon reductions.According to the International Energy Agency (IEA), effective measurement and verification are essential components of any successful industrial decarbonisation programme, ensuring accountability and continuous improvement
