Experience and Associations
With experience spanning both existing buildings and new developments, Imbue Sustainability provides strategic and technical support across a broad range of sustainability disciplines, including solar photovoltaic (PV) feasibility and implementation, energy modelling, utility data analysis, water efficiency strategies, carbon reduction planning, and operational performance optimisation. The company is particularly recognised for its ability to integrate sustainability initiatives into practical asset management frameworks, ensuring that environmental performance improvements are aligned with long-term operational and financial outcomes for clients.
Imbue Sustainability enjoys a longstanding collaborative relationship with Solid Green Consulting, having worked together on a wide range of sustainability consulting and asset performance projects. While Simon Penso heads up Imbue Sustainability, he is also a Director of Solid Green, where he established a new division, Solid Green Performance. All client green building and certification projects are undertaken by Solid Green, which includes Green Star Existing Building Performance (EBP) certification, Green Star New Build certification, and EDGE ratings.
The relationship between Imbue Sustainability and Solid Green has enabled the combined teams to deliver integrated sustainability solutions that extend beyond certification alone, with a strong emphasis on operational performance, renewable energy deployment, and ongoing asset optimisation. Together, the companies support clients in implementing practical sustainability strategies across property portfolios, including energy resilience planning, utility performance tracking, ESG reporting support, and the transition towards lower-carbon building operations.
