Science Seminar on Architectural design solutions to respond to climate change

On December 9, 2021, the Faculty of Architecture held a seminar on Science on solutions to design architectural works to respond to climate change in the period from 2050 to 2080. Due to the complicated situation of the Covid-19 epidemic in Da Nang, Vietnam. Nang, the seminar was only able to organize online form on a small scale. Participants include Faculty Council of Faculty of Architecture, lecturers of Faculty of Architecture and Architect Tran Nhat Tien (from Korea).

The seminar chaired by Dr. Architects. Le Minh Son, on behalf of the Faculty Council and Faculty of Architecture introduced the rapporteurs and ran the program.

Assoc. Dr. Nguyen Anh Tuan gave an overview report on the research topic and working process on behalf of the research team. This research focuses on the issue of climate change, forecasting climate change and climate scenarios of Vietnam in the medium and long term and applied to architectural research.

Assoc. Tuan also said that the research team applied many advanced research methods to solve the set goals, including general climate forecasting methods, climate downscale methods, simulation methods and optimization.

MSc. Le Thi Kim Dung also on behalf of the research team introduced the main product of the group's research: Draft Guidelines for architectural design to adapt to climate change in the period 2050-2080 to reduce greenhouse gas emissions. . The handbook is made up of three parts, which include detailed instructions on design solutions from enclosures to lighting, ventilation and HVAC solutions. The purpose of the research team is that through the Faculty Council and the Faculty of Architecture faculty members, they will receive comments, criticisms or questions related to this manual.

The results of the group's study showed:

- For the climate of regions of Vietnam, climate change significantly increases the average monthly temperature of localities in the country. Under the RCP4.5 average scenario, the average temperature increase is about 1.7 °C 2 °C. Under the extreme scenario RCP8.5, the average temperature increase is about 3°C ​​– 4°C. The trend of increasing temperature is quite consistent across regions and year round, and the North tends to increase the temperature more than the South. This is completely consistent with the rules of climate prediction models (IPCC, 2014).
- All types of commercial buildings considered here have increased carbon emissions. The increase corresponding to the long-term RCP 4.5 climate change scenario is from 6% ≈ 12%. Meanwhile, the increase corresponding to the long-term RCP 8.5 climate change scenario is from 12.6% ≈ 22%.
By calculating the data obtained from 240 times of simulating the performance of the base models and the optimal models under severe and less severe climate change scenarios, the results show that in the In the southern climate, the climate is warmer, the efficiency of the optimal model is always higher than that of the North. If appropriate passive design solutions are applied, the average carbon emission reduction is from 10.0% to 14.2%. The average reduction in the number of superheated hours ranged from 14.5% to 28.7%.
- The research team also made design recommendations for the climate zones of Vietnam.

Recognizing that this is an in-depth scientific content, Dr. Le Minh Son believes that the research team has made great efforts to produce good scientific results. The seminar agreed with the contents presented by the research team and wished all the best in the next step.

The seminar ended after nearly 2 hours of lively and frank work, bringing a lot of useful knowledge to both the reporter and the participants.
