Insights on Optimising Non-Domestic Buildings for Net Zero

UKGBC sets out retrofit strategies for commercial property owners

The UK Green Building Council will launch new guidance on commercial building retrofit in April 2026. The online event introduces two reports designed to help property owners cut energy use and carbon emissions in retail, logistics, and other non-domestic buildings.

Scheduled for Tuesday, April 14, 2026, from 10 am to 11 am, the webinar presents practical strategies for upgrading existing commercial property. It targets built environment professionals managing estates, portfolios, or individual commercial buildings. No specialist retrofit knowledge is required to attend.

The launch addresses a critical gap in UK decarbonisation efforts. Non-domestic buildings account for 23% of the UK’s built environment carbon emissions through operational energy use alone. With roughly 80% of buildings that will exist in 2050 already standing, retrofit represents the most direct path to meeting net zero targets.

Two reports form the core of the launch. The first examines retail and logistics buildings specifically. The second offers broader guidance applicable across commercial property types. Both documents connect technical retrofit measures to commercial decision-making.

Retail and logistics buildings face sector-specific challenges

The Building the Case for Net Zero report focuses on retail and logistics facilities. These building types present distinct retrofit challenges due to operational patterns, tenant arrangements, and physical characteristics.

The report catalogs commonly used retrofit measures for these sectors. For each intervention, it provides estimated impacts on energy performance alongside implementation costs. This pairing of technical and financial data helps property owners evaluate options systematically.

Timing decisions feature prominently in the guidance. The report explores when to undertake different retrofit measures, recognizing that capital expenditure cycles, lease events, and planned maintenance create natural intervention points. Aligning retrofit work with existing asset management activities can reduce disruption and cost.

The sector-specific approach reflects the diversity of commercial property. A distribution warehouse operates differently from a high-street retail unit. Consequently, retrofit strategies must account for building use, occupancy patterns, and operational requirements. Generic advice often fails when applied to specific property types.

Broader guidance applies across commercial building types

The second report, Delivering Net Zero, takes a wider view. It outlines practical actions for reducing operational energy use and carbon emissions across non-domestic buildings generally.

The guidance identifies key success steps. These include establishing baseline energy performance, identifying improvement opportunities, prioritizing interventions based on cost and impact, and integrating retrofit into asset management plans. The framework applies whether managing a single building or a diverse portfolio.

Practical actions form the heart of the document. Rather than theoretical principles, the guidance offers specific steps property managers can take. This includes operational improvements that require minimal capital investment alongside more substantial physical interventions.

The report recognizes that retrofit is rarely a single project. Instead, it typically unfolds over years as buildings are maintained, upgraded, and adapted. Therefore, the guidance emphasizes planning and sequencing. Early decisions about building fabric can enable or constrain later mechanical system upgrades.

Economic factors increasingly favor retrofit investment

Financial considerations now support retrofit activity beyond regulatory compliance. Buildings with stronger sustainability credentials attract higher capital values and rental income. This premium reflects tenant demand, investor preferences, and perceived risk profiles.

Minimum Energy Efficiency Standards are tightening. As regulations become more stringent, buildings that meet higher performance standards appear less risky to investors. Properties that require significant upgrades to remain legally lettable may face valuation challenges.

Energy costs continue to influence commercial property decisions. Buildings with lower operational energy consumption reduce occupier expenses. In competitive letting markets, this advantage can shorten void periods and support rental growth.

Access to finance increasingly depends on sustainability metrics. Lenders and investors apply environmental criteria when evaluating commercial property. Buildings with poor energy performance may face higher borrowing costs or limited investment appetite. Conversely, retrofit can improve asset attractiveness.

Who should attend the April launch event

The webinar targets built environment professionals involved in energy and carbon reduction. This includes property owners, occupiers, facility managers, designers, and consultants.

Specifically, the event suits those managing commercial buildings, estates, or property portfolios. Attendees might be evaluating retrofit options, planning capital expenditure, or developing net zero strategies for their assets.

Expertise in retrofit is not required. The guidance is designed to be accessible to property professionals who understand commercial real estate but may lack technical building physics knowledge. The reports translate technical concepts into commercial decision-making frameworks.

Participants will learn how to evaluate retrofit measures, understand typical costs and performance impacts, and integrate retrofit planning into existing asset management processes. The content connects technical interventions to business outcomes.

• Approximately 80% of buildings that will exist in 2050 are already constructed, requiring retrofit rather than new build solutions to meet climate targets.
• The Building the Case for Net Zero report provides sector-specific retrofit guidance for retail and logistics buildings, including cost estimates and energy performance impacts.
• The Delivering Net Zero report offers practical actions for reducing operational energy and carbon emissions across various non-domestic building types.
• Buildings with stronger sustainability credentials increasingly command higher capital values and rents, making retrofit commercially advantageous beyond compliance requirements.
• The guidance is part of UKGBC’s Advancing Net Zero Programme, now in its fifth year, which includes workstreams on commercial retrofit, residential retrofit, embodied carbon, and circular economy.

How the guidance fits within UKGBC’s net zero program

This launch forms part of UKGBC’s Advancing Net Zero Programme, now in its fifth year. The program takes a comprehensive approach to decarbonizing the built environment through multiple workstreams.

The program defines net zero standards for the sector. This foundational work establishes common definitions and performance criteria. Without shared standards, comparing building performance or verifying net zero claims becomes difficult.

Sector guidance enables understanding and action. The retrofit reports launched in April exemplify this approach. By translating technical requirements into practical guidance, UKGBC helps professionals implement net zero principles in their work.

Professional engagement spreads best practice. The program works directly with built environment professionals to implement net zero approaches. This includes training, resources, and collaborative initiatives that build sector capability.

Policy advocacy complements technical guidance. UKGBC argues for regulatory frameworks that support net zero delivery. This includes positions on building standards, planning policy, and fiscal measures that incentivize retrofit investment.

Commercial retrofit represents one of four core workstreams. The others address residential retrofit, embodied carbon reduction, and circular economy principles. Together, these streams cover the major sources of built environment emissions. However, commercial property retrofit remains critical given the sector’s emissions contribution and the longevity of existing building stock.

Practical steps for commercial property owners considering retrofit

Property owners should start by understanding current building performance. Energy Performance Certificates provide a baseline, though operational energy data gives a more accurate picture. Metering and monitoring reveal how buildings actually perform rather than theoretical ratings.

Identifying improvement opportunities requires assessment of building fabric, mechanical systems, and operational practices. Some measures deliver immediate returns with minimal investment. Others require capital expenditure but offer greater long-term savings. Understanding the range of options helps prioritize actions.

Aligning retrofit with asset management plans makes economic sense. Planned maintenance, lease events, and capital improvement programs create natural opportunities for intervention. For example, roof replacement provides an ideal moment to add insulation. Boiler replacement allows heating system upgrades.

Phasing work over time spreads costs and reduces disruption. A multi-year retrofit strategy can deliver substantial improvements through incremental measures. This approach suits property owners with limited capital budgets or buildings in continuous occupation.

Tenant engagement matters, particularly for energy-intensive uses. Occupiers control operational energy consumption through behavior and equipment choices. Consequently, retrofit should consider split incentives where landlords invest in fabric improvements but tenants pay energy bills. Green leases can align interests.

Professional advice helps navigate technical and financial complexity. Energy consultants can model retrofit options and predict performance improvements. Cost consultants provide accurate budget estimates. We support businesses with net zero planning and carbon reduction strategies that integrate retrofit into broader sustainability programs.
