2. Could new build houses in the UK be carbon negative in terms of embodied carbon dioxide?

3. Introduction CO 2 balance of a house 3 houses Summary Conclusions Questions Contents

4. Construction: 10% of UK energy. 53.2 Megatonnes CO 2 (2008). Problem Embodied CO 2 Solution? Houses as net CO 2 sinks. Introduction

5. Embodied CO 2 Released processing: Plastics, concrete, etc. Sequestered CO 2 Captured in: Timber, straw, etc. CO 2 balance = embodied - sequestered CO 2 CO 2 balance of a house

6. 1. 32 Wentworth Close

7. CO 2 balance 32 Wentworth Close Embodied CO 2 total = 35.7 tonnes Sequestered CO 2 total = 5.3 tonnes Balance: 30.4 tonnes CO 2

8. 2. Woodland house

9. CO 2 balance woodland house Embodied CO 2 total = 15 tonnes Sequestered CO 2 total = 32.2 tonnes Balance: -17.2 tonnes CO 2

10. 3. ModCell™ Balehaus™ Individual materials breakdown unavailable

11. CO 2 balances compared Embodied CO 2 Sequestered CO 2 CO 2 balance Tonnes CO 2

12. Summary 32 Wentworth Close  Carbon positive. Woodland house Carbon negative.  Bespoke. Balehaus™ Carbon negative. Mass production possible.

13. Conclusion Yes Increase straw and local timber. Reduce concrete, brick and plastics. Could new build houses in the UK be carbon negative in terms of embodied carbon dioxide?
