**Date:** [Date]

---

## 1. Introduction

This statement demonstrates how the proposed development addresses sustainability and energy performance requirements in accordance with national and local policy.

---

## 2. Policy Context

### National Policy
- NPPF Chapter 14 — Meeting the challenge of climate change, flooding and coastal change
- Building Regulations Part L (Conservation of fuel and power)
- Future Homes Standard [if applicable — phased introduction]

### Local Policy
- [Local Plan Climate Change / Sustainability Policy reference]
- [Any SPD or guidance on sustainability]
- [Percentage carbon reduction target above Part L — [X%] if required]

---

## 3. Energy Hierarchy

The design follows the energy hierarchy: **Be Lean → Be Clean → Be Green**

### Be Lean — Reduce Energy Demand
- [Fabric-first approach — enhanced U-values, airtightness, thermal bridging]
- [Passive design measures — orientation, natural ventilation, solar gain control]
- [Low-energy lighting and appliances]

### Be Clean — Supply Energy Efficiently
- [Efficient heating system — e.g. air source heat pump, ground source heat pump]
- [Heat recovery ventilation]
- [District heating connection (if available)]

### Be Green — Renewable Energy
- [Solar PV — [X] kWp installed capacity]
- [Solar thermal (if applicable)]
- [Battery storage (if applicable)]

## 4. Carbon Reduction Summary

| Measure | CO₂ Reduction |
|---------|--------------|
| Fabric improvements above Part L | [X%] |
| Efficient heating system | [X%] |
| Solar PV | [X%] |
| **Total reduction above Part L** | **[X%]** |

---

## 5. Water Efficiency

- Internal water use limited to [110 litres / 105 litres] per person per day
- Water-efficient fittings throughout
- [Rainwater harvesting (if applicable)]
- [Greywater recycling (if applicable)]

---

## 6. Waste & Materials

- [Percentage of construction waste diverted from landfill — target [X%]]
- [Use of recycled or reclaimed materials]
- [Responsible sourcing of timber (FSC/PEFC)]
- [Design for disassembly / circular economy principles]

---

## 7. Overheating Risk

- Overheating assessment completed in accordance with [CIBSE TM59 / TM52]
- [Mitigation measures: solar shading, ventilation strategy, glazing specification]

---

## 8. Electric Vehicle Charging

- [EV charging points provided in accordance with Building Regulations Part S]
- [Active charging points: [X], Cable routes for future active points: [X]]

---

## 9. Conclusion

The proposed development achieves [X%] carbon reduction above Building Regulations Part L and meets [local policy requirement]. The design follows the energy hierarchy and incorporates meaningful sustainability measures.
