Interior finishes play a significant role in energy modelling and the resulting Energy Performance Certificate (EPC) ratings. Proper selection and application of finishes can improve thermal performance, reduce energy consumption, and ensure more accurate EPC assessments.
Key Considerations
- Thermal Properties: Choose finishes with appropriate thermal conductivity, heat capacity, and reflectivity to match design specifications.
- Insulation Integration: Ensure wall, ceiling, and floor finishes work in conjunction with insulation to prevent thermal bridging.
- Moisture Control: Select finishes that manage moisture effectively to prevent dampness, which can affect thermal performance.
- Consistency: Apply finishes uniformly to maintain predictable energy performance across spaces.
Construction Techniques
- Coordinate interior finishes with building energy models during the design phase for accurate EPC calculations.
- Use certified low-emission materials that do not interfere with thermal modelling assumptions.
- Ensure proper installation of floors, walls, and ceilings to avoid gaps or thermal bridging.
- Integrate finishes with smart systems like automated shading or radiant heating where applicable.
Benefits
- More accurate energy modelling leading to reliable EPC ratings.
- Enhanced thermal comfort and energy efficiency for occupants.
- Compliance with building regulations and sustainable building certifications.
