Sustainability
Turn energy and carbon evidence into practical improvement
Virium helps organisations understand how their energy is used, establish a credible carbon position and convert the findings into technically sound, commercially workable reduction plans and projects.
Sustainability services
Select a service to view the scope and typical output
Energy Metering & Monitoring
We establish where, when and why energy is being used so decisions are based on measured performance rather than utility bills and assumptions.
- Metering strategy and gap assessment
- Electricity, gas and heat data review
- Sub-metering requirements
- Baselines, profiles and exception reporting
Energy Performance & Reduction Opportunities
We review how buildings, processes and utilities consume energy to identify reductions that are technically deliverable and commercially worthwhile.
- Consumption and baseload analysis
- Plant, process and building review
- Savings and cost assessment
- Prioritised opportunity register
Scope 1, 2 & 3 Assessment
We define the reporting boundary, assemble credible activity data and calculate emissions so the organisation understands where its material carbon impacts sit.
- Organisational and reporting boundaries
- Scope 1 and 2 inventory
- Material Scope 3 screening
- Data quality, factors and assumptions
Carbon Reporting & Decision Support
We turn carbon data into a clear management view that explains performance, material changes and the decisions needed to make progress.
- Performance indicators and reporting structure
- Year-on-year comparison and normalisation
- Evidence trail and data controls
- Management and client reporting
EPC & BREEAM Support
We coordinate the energy information, technical inputs and evidence needed to support EPC assessments and BREEAM requirements, working with appropriately accredited assessors where formal certification is required.
- Building and system information collation
- Energy evidence and design review
- Improvement recommendations
- Assessor and project team coordination
Decarbonisation Planning
We combine energy, carbon, cost and operational constraints into a staged plan that can move from ambition into funded and deliverable projects.
- Reduction targets and scenarios
- Efficiency, electrification and heat recovery
- On-site generation and low-carbon options
- Capital, programme and dependencies
01 Energy Metering & Monitoring
We establish where, when and why energy is being used so decisions are based on measured performance rather than utility bills and assumptions.
- Metering strategy and gap assessment
- Electricity, gas and heat data review
- Sub-metering requirements
- Baselines, profiles and exception reporting
Typical output: Metering and monitoring plan with a clear performance baseline.
02 Energy Performance & Reduction Opportunities
We review how buildings, processes and utilities consume energy to identify technically deliverable and commercially worthwhile reductions.
- Consumption and baseload analysis
- Plant, process and building review
- Savings and cost assessment
- Prioritised opportunity register
Typical output: Prioritised opportunity register with estimated savings, investment and next actions.
03 Scope 1, 2 & 3 Assessment
We define the reporting boundary, assemble credible activity data and calculate emissions so material carbon impacts are understood.
- Organisational and reporting boundaries
- Scope 1 and 2 inventory
- Material Scope 3 screening
- Data quality, factors and assumptions
Typical output: Documented greenhouse gas inventory with assumptions, exclusions and data gaps.
04 Carbon Reporting & Decision Support
We turn carbon data into a clear management view that explains performance, material changes and decisions required.
- Performance indicators and reporting structure
- Year-on-year comparison and normalisation
- Evidence trail and data controls
- Management and client reporting
Typical output: Concise reporting pack and repeatable reporting method.
05 EPC & BREEAM Support
We coordinate the energy information, technical inputs and evidence needed to support EPC assessments and BREEAM requirements.
- Building and system information collation
- Energy evidence and design review
- Improvement recommendations
- Assessor and project team coordination
Typical output: Traceable evidence pack and action schedule for the appointed assessor or project team.
06 Decarbonisation Planning
We combine energy, carbon, cost and operational constraints into a staged plan for funded and deliverable projects.
- Reduction targets and scenarios
- Efficiency, electrification and heat recovery
- On-site generation and low-carbon options
- Capital, programme and dependencies
Typical output: Prioritised short-, medium- and long-term delivery roadmap.
