A renovation plan is a prioritised roadmap for modernising and improving the energy performance of an existing building. It brings together measures for the building envelope and building services / MEP systems, cost-benefit considerations, timelines and documentation - based on reliable as-is data from the building survey and clearly defined target values.
Why is a renovation plan important?
- Clarity and priorities: Structured phases, from short-term to medium- and long-term measures, help prevent ad hoc actions with little impact.
- Measurable benefits: Transparent savings targets, CO2 reduction, comfort improvements and value preservation - including budget and payback.
- Legal certainty and funding: Clean documentation, such as links to the energy performance certificate and the EPBD framework, can support approvals and funding applications.
- Smooth implementation: Dependencies and construction sequences are coordinated, reducing duplicate appointments and change orders.
Common mistakes and misconceptions
- Individual measures without a system view: Insulation, windows and building services must be coordinated. Otherwise, moisture and comfort problems may occur.
- Renovating without data: Missing as-is documentation or energy consulting can lead to poor investments and weak evidence.
- No quality assurance: Without documented checks such as thermography and airtightness testing, the effects are difficult to prove.
- Media discontinuity: Paper lists instead of integrated, versioned data in BIM or CAFM systems increase the error rate.
- Unclear target values: Without measurable KPIs such as kWh/m2a, CO2 and comfort, the plan cannot be managed effectively.
Renovation plan vs. retrofit plan
- Retrofit plan: A standardised, official document or format with formal requirements, regulated at national level.
- Renovation plan: An operational, project-specific roadmap. It can deepen the content of the roadmap and focus on implementation detail, quantities and construction sequencing.
FAQ
What data do I need for a reliable renovation plan?
Current geometry, such as measured drawings or as-is plans, component structures, thermography / U-values, the current condition of building services and consumption data - all stored centrally and versioned.
In what order should measures be implemented?
Start with the building envelope and airtightness, then windows, and finally systems engineering and controls - while taking dependencies and comfort into account.
How do I link the plan with operation and documentation?
Maintain the results in as-built documentation, BIM or CAFM systems, update the energy performance certificate, store inspection reports, monitor KPIs cyclically and iterate the plan.
