Implementing deep energy renovations in condominiums requires clear decision-making frameworks and accessible financial insights that help homeowners understand the impact of renovation scenarios on living costs. Structured tools that simplify complex financial information are essential to support informed investment decisions and accelerate integrated renovations.

This manual is intended for professionals and organisations supporting Condominium Associations (CAs) in planning and implementing energy renovations. It combines a structured renovation roadmap with a financial calculation tool designed to provide a clear overview of costs, benefits, and decision pathways.

This guidebook:

• Describes a renovation roadmap guiding CAs through key phases and decision milestones in the renovation process
• Introduces a simplified financial calculation tool comparing living costs before and after renovation
• Explains how energy savings, subsidies, financing costs, and maintenance planning influence investment decisions
• Presents a methodology for comparing renovation scenarios based on monthly housing expenses and total cost of ownership
• Supports communication between stakeholders by translating technical and financial complexity into clear indicators

By combining a structured roadmap with accessible financial analysis, the deliverable helps Integrated Home Renovation Services (IHRS) facilitate informed decisions and advance deep renovation projects in condominium buildings.
