# Energy 1.1 Thermal Performance Rating - Non-Residential
# Applies to
Non-residential developments
# Objective
To reduce reliance on mechanical systems to achieve thermal comfort in summer and winter - improving comfort, reducing greenhouse gas emissions, energy consumption, and maintenance costs.
# Summary
Points are awarded when the building's thermal fabric reduce heating and cooling energy consumption below the reference case. (BCA Section J), as follows:
- >10% reduction - 12.5% score
- >20% reduction - 37.5%
- >30% reduction - 50%
- >40% reduction - 62.5%
- >50% reduction - 75%
- >60% reduction - 87.5%
- >70% reduction - 100%
# Documentation & evidence required
- If using the DtS method, provide your insulation specifications (R-values), preliminary glazing calculation, heating and cooling system type and CoP/EER, and water heating system details.
- If you are providing your own energy modelling, provide your model assumptions and results.
