Q & A

What challenge does Ashan Rehman identify as her biggest in the field of sustainability?

Ashan Rehman feels the biggest challenge in sustainability is affordability. While everyone should have access to technology and comfort, the current challenge is making sustainable technology more affordable and efficient for everyone.

How did Ashan Rehman decide to pursue a career in sustainability?

Ashan Rehman realized during her architectural studies that architecture is not just about aesthetics but also about environmental responsibility. Growing up in a place with vernacular architecture that used sustainable methods also inspired her to pursue sustainability in her career.

What are some software tools Ashan uses for energy modeling and sustainability projects?

Ashan Rehman uses a variety of software depending on the project. For example, while studying at Carnegie Mellon, she used Climate Studio, Hope Tool, and Ladybug. Professionally, she uses Ecotrope and eQuest.

How does Ashan Rehman believe BIM contributes to sustainability?

Ashan believes BIM helps by reducing construction waste and enhancing the lifespan of buildings. It allows for the fabrication of construction modules, which can prevent over-ordering of materials, and also facilitates tracking of carbon data and retrofitting decisions for improved efficiency.

What misconception about sustainability does Ashan Rehman aim to clear?

Ashan wants to address the misconception that sustainability is only affordable for the rich. She argues that while the initial costs might be high, sustainable investments pay off over time through reduced operational costs like energy and gas.

What are Ashan Rehman’s favorite projects in her sustainability career?

Ashan mentions two projects: one was a research project on Indian vernacular architecture, particularly studying 'Jali' construction for thermal comfort and daylight optimization. The second was a creative project where she imagined a future where technology enables sustainable living.

What advice does Ashan Rehman offer to young professionals wanting to specialize in sustainability?

Ashan advises that aspiring sustainability professionals should understand the wide range of careers in the field, from energy modeling to ESG consulting, data analysis, and software development. She encourages people to identify their interests and pursue relevant courses accordingly.

What has been Ashan Rehman’s experience working with 1s2x as a mentor?

Ashan has found her mentoring experience with 1s2x rewarding. She appreciates that students are eager to learn and improve themselves. She also values that 1s2x provides not only BIM training but also industry guidance and mentorship opportunities.

What role does Ashan Rehman believe architects play in combating climate change?

Ashan highlights that 40% of carbon emissions come from the built environment, making architects crucial in the fight against climate change. BIM helps in reporting carbon data, making buildings more energy-efficient, and supporting retrofitting efforts to avoid unnecessary demolitions.

How does Ashan Rehman view the global responsibility in sustainability efforts?

Ashan stresses that sustainability should be viewed holistically. It’s not just about saving money or individual health benefits; it's about the broader environmental impact. She emphasizes that the effects of climate change will disproportionately affect poorer communities.
