1. Energy savings innovations - Bioclimatic building designs Marta Lam 14-Jan-2002

2. General Summary  Introduction  Undergraduate honours project  Current research  Bioclimatic building designs

3. Introduction  Graduated in 2000  BSc (Hons) Building studies  Part-time research assistant  Part-time MPhil/PhD  Honours project carries on to research

4. Undergraduate Honours Project - Overview  Aim: To investigate the energy impact of deciduous plant growth on bioclimatic office buildings  Literature review, state of the art  Identify buildings and plants  Develop computer models  Computer thermal analysis  On 2 locations: UK and USA

5. Undergraduate Honours Project – Case Study: Mesiniaga Building

6. Undergraduate Honours Project – Case Study: Santiago office building

7. Undergraduate Honours Project – Theoretical models

9. Current Research  Similar to Honours project – but on naturally ventilated buildings  Working title: Environmental performance of deciduous plantings on naturally ventilated buildings  Plants act as external shading devices

10. Drive of the research area  Recent change in climate  Hotter summers – more a.c. systems  Direct conflict with national commitment of reducing CO 2 emission  Sustainable building designs – Bioclimatic designs  What are bioclimatic buildings/ designs??

11. Meaning of ‘Bioclimatic’  Inspired by nature, optimising and using the environment  To conserve resources  To control and also fully utilise solar radiation  Good air quality inside building  Building fabric to absorb and release heat on a daily cycle, whilst insulating in cold times  Using the above factors to increase comfort  Some examples…..
