Renovate smarter
A Check First approach to EPBD implementation means assessing building performance and low-temperature readiness before major renovation, heating, and electrification decisions are made. By reducing avoidable energy demand first, Member States can make clean heat deployment more cost-effective, ease pressure on electricity grids, and support better outcomes for households.
The Energy Performance of Buildings Directive’s (EPBD) implementation is now entering a decisive delivery phase. Over the coming years, Member States will define national renovation pathways, financing schemes, and electrification strategies that will shape Europe’s future.
A Check First approach supports this implementation by helping policymakers integrate building performance checks into the EPBD’s core instruments: National Building Renovation Plans, minimum energy performance standards, cost-optimality requirements, energy performance certificates, renovation passports, one-stop shops and public support schemes.
The principle is simple: assess the building first, reduce avoidable demand where needed, then size and support heating and electrification measures on the basis of better performance data.

A "check first" approach supports EPBD implementation in three critical ways.
Checking first helps reduce unnecessary demand on the energy system. Better-performing buildings can lower peak demand, reduce pressure on distribution grids, and make more electricity capacity available for industry, transport and growth.

Read More →Check First means avoiding renovation decisions based on guesswork. A building that performs better needs less energy, is easier to keep comfortable, and may require a smaller heating system. This cuts out avoidable running and instalment costs and makes public support schemes more effective.

These policy tools show how national policymakers can use existing EPBD instruments to ensure that building performance is assessed before major heating electrification decisions are made.
Member States can use EPCs within a check first approach to guide decisions on renovation steps, while recording progress through national databases and digital building logbooks.

Explore the policy tool →Member States can add low-temperature readiness checks to district-heating connections, heating-system inspections and public support schemes. This makes clean heat deployment more cost-effective by ensuring systems are selected and sized based on the building’s actual performance.

The Low-Temperature Readiness (LTR) Calculator helps turn the Check First principle into a practical assessment.
It gives public authorities, energy practitioners, auditors, and one-stop-shops a way to assess whether buildings are ready for efficient low-temperature heating systems, such as heat pumps, or whether targeted improvements to the building envelope should be considered first.
Case studies and implementation examples show how assessing building readiness first can help deliver clearer renovation decisions, lower demand and more effective outcomes for households and energy systems.
A renovation project focused on improving the building envelope before assessing wider renovation outcomes. By improving the envelope first, the renovated building reduced average energy use by 55% and lost heat twice as slowly, with more stable indoor temperatures and noticeable savings on energy bills.

The renovation of social housing for 455 households prioritised assessing the need for building-envelope improvements before introducing clean energy solutions. Because buildings were made more efficient first, the heating and energy technologies could work more effectively, achieving a 94% reduction in heating demand while tenants remained in their homes throughout.

A 1955 building with 39 dwellings began with an energy audit to identify where envelope improvements were needed. By prioritising improvements to walls, façade and roof, the project achieved a 37% energy performance improvement at an average cost of €14,400 per dwelling.

It means requiring a building performance and low-temperature readiness check before major heating, renovation, funding or electrification decisions are made. For national policymakers, the approach can be embedded in national law and implementation measures through EPCs, renovation passports, one-stop shops, minimum energy performance standards, heating-system inspections, public support schemes and National Building Renovation Plans. The aim is not to create a new policy framework, but to make existing EPBD tools work in the right order. A Check First approach helps Member States identify avoidable energy demand, target the worst-performing buildings, improve heat pump readiness and reduce pressure on electricity grids. It also gives energy professionals a clearer assessment route and gives industry a stronger, evidence-based case for demand reduction before system expansion.
| Decision point | Check First approach | No Check First approach |
|---|---|---|
| Starting point | Begin with an EPC, energy audit, home energy assessment or low-temperature readiness check before funding or installation decisions are finalised. | Select and fund the heating system before the building’s real heat loss, fabric condition and low-temperature readiness are understood. |
| Building envelope | Check roof or loft, walls, floors, windows, doors, airtightness and ventilation. Recommend insulation or targeted envelope upgrades where heat loss is high. | Leave high heat loss unaddressed, forcing the new system to compensate for avoidable demand. |
| Heat pump readiness | Assess whether the building is ready, ready after targeted improvements, or should prepare first through envelope or heating-distribution measures. | Assume electrified heating will perform well without confirming whether the building can operate efficiently at lower flow temperatures. |
| Heating system sizing | Size the heat pump or other electrified heating system on the basis of verified or reduced heat demand. | Risk an oversized system that is more expensive to install, less efficient to run and harder to optimise. |
| Running costs and comfort | Lower avoidable heat demand, improve comfort and reduce exposure to high electricity consumption during cold periods. | Risk higher running costs, comfort complaints and greater exposure to energy price volatility, especially in winter. |
| Grid and peak demand impact | Reduce peak heating demand before electrification, helping ease pressure on distribution grids and freeing capacity for other sectors. | Add avoidable electricity demand to the grid, particularly during winter peaks and in areas with constrained local networks. |
| Public funding route | Link support to clear readiness categories: ready, ready after targeted improvements, or prepare first. Fund insulation and clean heat together where appropriate. | Support isolated equipment replacement without ensuring the building is ready, reducing value for money from public funding. |
| Renovation pathway | Connect the owner to a renovation passport, one-stop shop or staged renovation plan where deeper works are needed. | Increase the risk that later works are needed to correct earlier decisions, causing extra disruption and cost. |
| EPBD implementation value | Align MEPS, EPCs, renovation passports, one-stop shops, clean heat funding and grid planning around a single sequence: assess, reduce demand, then electrify. | Fragment EPBD delivery by treating heating replacement, building renovation and energy-system planning as separate decisions. |
| Policy outcome | Better value for households, more cost-effective electrification and stronger progress on worst-performing buildings. | Higher risk of lock-in, inefficient electrification, avoidable grid pressure and weaker outcomes for households. |
EPCs and renovation passports work best when they are linked together. An EPC provides the starting point by identifying the current energy performance of a building and highlighting major sources of heat loss. A renovation passport then turns that information into a step-by-step roadmap for staged renovation. This link is a core policy ask for EPBD implementation. The EPC should not stop at a rating. It should direct building owners towards a renovation passport, a one-stop shop or a low-temperature readiness tool where deeper works or clean heating decisions are being considered. A Check First approach connects EPCs, renovation passports and digital building logbooks so that each renovation step prepares the building for the next: performance check, demand reduction, low-temperature readiness, clean heating and verified improvement.
Member States can make clean heat funding sequence-aware by requiring a building performance and low-temperature readiness check before public support is approved for major heating upgrades, heat pump grants or district heating connections. The check should classify buildings into three simple categories: ready for clean heating, ready after targeted improvements, or prepare first. Buildings that are ready can proceed directly. Buildings needing targeted improvements can receive combined support for insulation, airtightness, radiator upgrades and clean heating. Buildings with high avoidable heat loss should be directed first towards renovation advice and staged renovation support. This approach helps public money reward better sequencing, not isolated replacements. It can reduce the risk of oversized systems, unnecessary running costs and additional pressure on electricity grids.
An EPC and heat pump readiness checklist should combine building performance, heat-loss and heating-system information. It should include the building envelope, roof or loft insulation, walls, floors, windows, doors, airtightness, ventilation, heating distribution, radiator capacity, controls, domestic hot water and the flow temperature required to heat the building comfortably. For policymakers, the checklist should not only describe the current building. It should also recommend the next step: ready for clean heating, ready after targeted improvements, or prepare first through envelope upgrades or a staged renovation plan. Adding heat pump readiness to EPCs, supported by a low-temperature readiness tool or similar assessment method, can make EPCs more useful for households, one-stop shops, installers and funding bodies. It turns the EPC from a compliance document into a practical Check First gateway.
