What Makes a Smart Sustainable Technology? With Sonu Panda and Becca Rushin


In the eighth episode of Season 10 of the Propcast, host Louisa Dickins is joined by Sonu Panda, the CEO of Prescriptive Dataand Becca Rushin, the Director of ESG at Jamestown. Becca and Sonu discuss challenges in the industry including the impact of the current geopolitical climate and whether this will slow down the journey to net zero.

Becca and Sonu share their career journeys to ESG and technology. In this episode you’ll hear Sonu explain more about script data and how it improves sustainability in buildings. Becca talks about Jamestown’s sustainability and social responsibility initiatives and shares information on their green program and charitable foundation.

The key takeaway from this episode is that people want to work in healthy buildings and environments, however, achieving carbon neutrality through offsets is not enough. Instead, true science based approaches are what’s needed to tackle the bigger issue of climate change.

[2:43] Becca: How did you get to become in the ESG space at Jamestown and how do you know Sonu?

  • I learnt about sustainability whilst I was studying environmental policy, from there I decided to go to the Netherlands to study sustainable development.
  • Over the last ten years I have focused on putting systems into place that have evolved from the benchmarking of monthly utility performance to more robust energy management platforms.
  • I first heard about Prescriptive Data through a friend of mine that worked there. I then sat on a panel with Sonu and listened to John Gilbert from Rudin talk about the evolution of the Nantum platform.

[5:41] Sonu: How did you become CEO of Prescriptive Data and can you tell us more about the product?

  • I have always been in the enterprise software business, when I had my son I started thinking about how I can work in a field that is fundamentally important to the world and what will have an impact, this led me to meeting Rudin Management.
  • Prescriptive Data started as a project within the Rudin Management portfolio, we are now entirely independent. Our original premise was the idea that commercial offices exist to provide productive and comfortable workplaces, a big part of that is indoor air quality and thermal comfort.
  • We used occupancy sensors so we could learn the rhythms of the building and correlate with the technology controlling the air quality in the buildings. This was the beginning of the Nantum OS.

[12:33] Becca: Can you talk us through Jamestown’s initiatives, what your strategy is and what you’re working on at the moment?

  • The Jamestown Green program and the Jamestown Charitable Foundation are ultimately about our efforts to reduce Jamestown’s impact on the environment and support the communities where we own property and where we operate. 
  • The Charitable Foundation was established to help host community events that benefit nonprofits. We invest in metropolitan centres and then support the nonprofits that make those cities more desirable places to work.
  • The Jamestown Green program is for sustainability efforts. We look to find management practices and initiatives that help increase our net operating income, drive financial performance at our assets and make our assets more valuable 

[16:45] Becca: Are there any other companies that you are piloting on the portfolio that are helping to reduce emissions more specific to ESG?

  •  I’ve been focused on first just having a system in place, and over the last couple of years focusing more on the quality of the platform and matching specific tech solutions and providers with a specific type of asset.
  • We have partnered with a company called Carbon Lighthouse, they identify energy saving products that the team then implements. They help back up those projections with their energy models and monitor the projects so they stay in place over the long term.

[19:22] Sonu: What is the main challenge you face in the industry?

  • Everybody is worried about the geopolitical situation, however I try not to think about it, largely because there is so much momentum around sustainability.
  • I see a more widespread recognition that climate change is real, that achieving carbon neutrality through offsets is not enough and that true science based approaches are what’s called for.


L– Touch on the main lessons you have learnt throughout your career.

Sonu – The RHINO principle, keep your eye on the prize, there is an impact to be made, we are doing really important work and we must stay focused on it.

M – Please give a mention to anyone / product / service.

Becca –  I think that part of the reason that I’ve been successful is because I’ve been relentless about networking and finding partnerships.

R – What has been the most  rewarding  aspect of working in PropTech?

Sonu: The fact that we are working on something that is a shared concern and if we resolve it will be a shared benefit.

E – What are you excited about in the future of PropTech? 

Sonu answered earlier in the show: I’m excited about the transition towards net zero I’ve witnessed in the last six months. I think it’s a great opportunity because people have realised something needs to be done.
