2. Six-month Review – Project Name, Number, Report Period Natural Ventilation, Solar Heating and Integrated low-energy Building Design Brief Description of Project: In this project we propose to draw together experts involved in architectural design, building engineering, natural ventilation processes, as well as in building environmental safety, from Cambridge, MIT and BP. Through a combination of complementary fundamental research, building monitoring and a joint design project for a specific new building, we aim to build up the foundations of this key emerging discipline in building design.

3. Six-month Review – Project Name, Number, Report Period Summary of Intended Outcomes: The objectives of the project will be to develop designs and technologies to: reduce energy costs of maintaining a comfortable environment with buildings through use of solar power, natural ventilation processes and improved building materials; improve air quality within buildings, to mitigate against sick building syndrome; improve emergency building ventilation in case of discharge of hazardous gases or fires. We also plan to invest considerable effort in communicating these technologies to the architectural and building engineering communities

4. Six-month Review – Project Name, Number, Report Period Progress In Past Six Months Important activities, collaborations: There has been continuous collaboration between MIT(Architecture, EECS, Mechanical Engineering) and CU (Martin Centre, BPI) working on joint projects in UK and US. This includes exchange of students, staff for short periods, multiple joint meetings in UK, US: at least 6 per year. There has been joint participation in giving short courses, conference workshops for industry professionals and academics from other universities. CU and MIT have maintained close cooperation with industry on monitoring of advanced buildings, design, analysis and planning of innovative facilities. This includes ongoing meeting with BP Global Property Management and Services in UK and US on major new BP sites.
