Head of Design Integration
Proposer Additional Info
I am the Head of Design Integration at Reframe Systems. I am currently focused on leading the decarbonization strategy and developing the system architecture for Reframe's platform. I am an MIT-trained architect, specialized in urbanism, embodied carbon, and digital design-fabrication. I was recently awarded with ENR Top 20 Under 40 Young Professionals national award (from the AEC industry). Prior to joining Reframe, I spent 3 years at the National Renewable Energy Laboratory (affiliated with US Department of Energy) in Golden, CO as a research engineer, where I worked with US-based modular construction companies and deep-energy retrofit teams to integrate energy efficiency and solar-plus-storage in multi-family housing and develop decarbonization roadmaps for the industry partners. I was born and raised in Andaman & Nicobar Islands of India, where I experienced the importance of self-reliance and technological resilience in the face of climate change.
Proposed Session Description
The installation of solar-storage systems for new and existing housing is expensive due to high hard and soft costs from installation, complex balance-of-systems, sales, permitting, and inspection. This session will introduce Reframe Systems’ innovative approach to decreasing these costs by prefabricating solar-integrated roof cassettes and battery kits at scale in microfactories, improving productivity and safety of the workforce. Cost reduction data from first microfactory will be presented.
Why is this session important?
The integration, installation and deployment of rooftop solar PV systems and small home batteries on a large scale, for new and existing housing, pose significant challenges not because of the technology or science involved, but due to the unit economics. This is caused by the high hard costs resulting from site installation labor and material expenses of complex balance-of-systems, as well as the high soft costs that come from sales, marketing, permitting, inspection, interconnection, and supply chain premiums. These costs make up for 50% of the total installed cost for residential systems, as reported by the latest Solar-plus-storage benchmarking study by NREL. Solar-plus-storage systems, although necessary for many stretch codes and for Passive House PHIUS ZERO certification, contribute to the overall project costs of constructing and retrofitting homes to be net-zero carbon. In fact, they are the highest contributor to incremental costs for net-zero carbon when compared to other net-zero strategies/technologies such as high-performance envelope and heat pumps. Although state tax rebates and IRA incentives cover 30% of equipment costs (including solar PV panels, microinverters, and batteries), it is crucial to reduce the remaining hard costs and total soft costs. Other challenges include split incentives, lack of knowledge about solar PV systems and batteries in the home building industry, and complex coordination with specialized installers and electricians on-site. There is an ideal opportunity to lead the effort in this macro environment, and these challenges are important to be discussed right now to unlock more value as we start scaling both retrofit and new construction projects. Reframe Systems is responding by developing an innovative design integration and manufacturing platform to prefabricate solar-integrated roof cassettes and battery kits at scale in microfactories. Our approach aims to significantly improve climate tech workforce productivity, safety, final install quality, and reduce overall project costs. By doing so, we take one step closer to achieving our mission of deploying net-zero carbon homes for everyone on a massive scale. In this session, we will be presenting cost reduction data analysis from first microfactory. We will be describe learning from mistakes as well as from successes from our continuous improvement process in the microfactory. We will also present the training module we use in the microfactory that lends itself to workforce development and training.
Diversity and Inclusiveness
The speaker, Ankur Podder, was born and raised in the Andaman & Nicobar Islands of India and moved to the US back in 2017 for grad school at MIT. Ankur's motivation has been to serve vulnerable and marginalized communities facing challenges with housing crises and energy burdens. His experience growing up on remote islands motivated him to continue working with diversity, equity, and inclusion at the core of all his projects. His research work at MIT focused on the self-reliant development of island communities such as Puerto Rico and Maine's islands to achieve low embodied carbon and zero operational emissions with their affordable housing projects. Ankur spent three years with the Buildings Research Group at the National Renewable Energy Laboratory (NREL), focused on deploying affordable, net-zero energy buildings at scale. Most of these projects were funded by the US Department of Energy and the US Department of Housing and Urban Development (HUD). The HUD-funded project was specifically designed to add resilience to new and existing buildings for low-income communities. Ankur also led an education and workforce development project at NREL, funded by the US Advanced Manufacturing Office, that primarily focused on developing career maps and resources for underserved communities with a focus on diversity, equity, and inclusion. The content of this session brings to the forefront the need to reduce the cost of solar-plus-storage systems to make such technologies accessible to underserved communities. The high upfront costs continue to place a major energy burden on tenants or homeowners. Compared to middle- and upper-income households that spend 5% or less of their total household income on energy purchases, low-income households spend 10% or more of their income on energy expenses. “Low-income individuals typically are less likely to participate in clean distributed energy resources (DERs) due to critical barriers such as lack of access to capital, lower credit scores, and lower rates of homeownership. Unless these gaps are addressed, the transition to clean energy resources could widen the energy burden gap between high- and low-income households…” as noted in the report "Encouraging the Development of Distributed Energy Resources in Texas." Reframe Systems is on a mission to build inspiring, net-zero-carbon homes for all, at massive scale. This can only be achieved by lowering the project costs through the entire value chain of deploying solar-plus-storage systems for both single-family and multifamily housing.
Learning Objectives
Acquire fundamental knowledge and rich data analysis of how to optimize the design and manufacturing of solar-integrated roof cassettes and battery kits
Recognize the challenges and complexities with designing, deploying, inspecting, and interconnecting solar-plus-storage systems in on site
Evaluate how prefabricating in microfactories improve workforce productivity, enhance workforce safety, and reduce total costs compared to traditional business-as-usual approach of on-site installation based on rich data analysis presented
Participate in improving Reframe's climate tech workforce development and training module by engaging in a collaborative exercise

Additional Comments
This is the first time we will present our work and our data on this innovation approach. We want to leverage the BuildingEnergy NYC platform as the first large event to introduce the system and present the data analysis from our microfactory. We are currently applying for an InnovateMass grant from MassCEC. We have the City of Somerville as a demonstration partner to deploy and demonstrate our innovation as part of our Net-Zero Triple Decker Program. Also happy to be part of a larger panel or presentation.
Target Audiences Level of Expertise
