Public Sector Decarbonisation Solutions

Energy Efficiency Surveys

Understanding how energy is used across your estate is the first step toward reducing it. Our energy efficiency surveys provide detailed insights into building performance, identifying opportunities for low-cost improvements and strategic upgrades.
 
We assess:

 
• Building fabric and insulation
• HVAC systems and controls
• Lighting and electrical systems
• Occupancy and operational behaviours

 
Our surveys are designed to support funding applications, compliance reporting, and long-term energy planning.

Heat Decarbonisation Plans

Heating is often the largest source of carbon emissions in public buildings. Our Heat Decarbonisation Plans (HDPs) provide a structured roadmap to transition away from fossil fuels—and align with funding criteria and the latest government guidance.
 
We deliver:

 
• Site-level heat demand analysis
• Low Carbon heating options appraisals
• Technology focused feasibility studies (e.g. heat pumps, district heating)
• Phased implementation plans
• Cost modelling and carbon impact forecasting

 
HDPs are essential for securing funding and guiding strategic investment in low-carbon heating.

Detailed Design and Tender Specification

Once your strategy is in place, we support your journey from concept to delivery. Our team provides detailed design and tender documentation to ensure retrofit and decarbonisation projects are technically sound, compliant, and ready for procurement.
 
We offer:

 
• Technical drawings and specifications
• Performance requirements and standards
• Tender analysis with independent evaluation
• Contractor liaison and clarification support

 
This service ensures your projects are delivered to specification, on time and within budget.

Project Management Support

Decarbonisation projects often involve multiple stakeholders, contractors, and funding bodies. Arthian provides project management support to keep everything on track—from mobilisation to handover.
 
Our support includes:

 
• Programme planning and milestone tracking
• Risk and issue management
• Stakeholder coordination
• Witness testing and system commissioning oversight
• Reporting and funding body liaison

 
We act as an extension of your team, ensuring smooth delivery and clear communication throughout.

PAS 2038 Retrofit

PAS 2038 is the British Standard for non-domestic building retrofit. Arthian supports public sector organisations in delivering PAS 2038-compliant retrofit projects, ensuring quality, consistency, and long-term performance.
 
We provide:

 
• Retrofit assessments and planning
• Design and specification aligned with PAS 2038
• Monitoring and verification of outcomes
• Integration with wider decarbonisation strategies

 
PAS 2038 ensures retrofit works are evidence-based, measurable, and aligned with best practice for complex buildings.
