RentalCal focused on profitability calculation for rental housing retrofitting, and CRREM built science-based decarbonisation pathways for the real estate sector.
TiasNimbas Business School B.V.
Dutch business school specializing in energy efficiency economics, real estate decarbonisation, and public value co-governance in EU research consortia.
Their core work
TiasNimbas is a Dutch business school (part of Tilburg University's ecosystem) that brings management science and governance expertise into EU research projects. Their core contribution is analyzing the business case and policy frameworks around building energy efficiency — specifically how to make retrofitting financially viable and how to govern public-private collaboration in the digital age. They bridge the gap between technical energy solutions and the economic/governance models needed to implement them at scale.
What they specialise in
COGOV (their largest project at EUR 526K) studied co-production, co-creation, and network governance in public service renewal.
RentalCal specifically tackled the landlord-tenant split incentive problem that blocks energy retrofitting in rental housing.
COGOV explored how digital transformation changes public governance and strategic management approaches.
How they've shifted over time
Their early work (2015-2018) was firmly rooted in the financial mechanics of building energy efficiency — calculating retrofitting profitability and solving the split incentive problem in rental housing. By 2018, their focus broadened significantly toward governance and public value co-creation, as seen in COGOV. The shift suggests a move from narrow financial analysis toward understanding how institutions and citizens collaborate to deliver public outcomes in a digital context.
Moving from sector-specific financial analysis toward broader governance and institutional design questions, particularly around digital-era public service delivery.
How they like to work
TiasNimbas has participated exclusively as a partner, never coordinating — consistent with an academic institution contributing specialized management/governance expertise to larger consortia. Across 3 projects they worked with 23 unique partners in 11 countries, indicating they integrate well into diverse European teams rather than sticking with a narrow circle. Their role pattern suggests they are sought for their analytical and conceptual contributions rather than technical execution.
A moderately broad European network spanning 23 partners across 11 countries, built entirely through participant roles. For a small business school with only 3 projects, this is a relatively wide reach, suggesting their expertise is valued across different consortium configurations.
What sets them apart
TiasNimbas occupies a rare niche: a business school that applies management science directly to energy transition and public governance challenges within EU research. Most business schools stay in advisory or teaching roles — TiasNimbas actively participates in research consortia, bringing financial modelling and governance design to technically-oriented projects. For consortium builders, they offer the "business case" and "governance design" piece that many technical projects lack.
Highlights from their portfolio
- COGOVTheir largest project (EUR 526K) and a significant pivot toward governance research — co-production and digital-era public management.
- RentalCalAddressed a concrete market failure (split incentives in rental housing retrofitting) with a practical profitability calculation framework.
