Imbue Sustainability is a key driver of South Africa’s transition towards a more sustainable built environment.
About
Combining technical expertise and deep understanding of sustainability in the built environment
Imbue Sustainability supports property developers, corporates, asset and portfolio managers, and institutions to navigate the complexities of transforming property assets towards optimum performance and profitability.
As a leading South African sustainability and renewable energy consultancy, Imbue Sustainability is focused on transforming sustainability strategy into measurable operational and financial performance, playing a key role in supporting the transition toward more efficient, resilient, and financially optimised commercial and industrial built environments. Rather than treating sustainability as a compliance exercise, the firm focuses on delivering practical, data-driven solutions that improve how buildings and portfolios actually perform in energy consumption, operating cost, and long-term asset value.
Performance-driven sustainability for the built environment
Focusing on performance-driven sustainability for the built environment, Imbue Sustainability works across commercial and industrial sectors where energy use, utility efficiency, and infrastructure performance directly impact profitability. The company identifies inefficiencies within buildings and portfolios and converts them into structured opportunities for improvement through renewable energy systems, utility optimisation, and strategic energy planning.

Imbue Sustainability provides a fully integrated service offering that spans the entire lifecycle of sustainability and energy projects.
This includes early-stage feasibility assessments, technical design, procurement support, contract negotiation, construction oversight, and long-term performance monitoring. By remaining involved throughout the lifecycle, Imbue Sustainability ensures that project outcomes align with both operational requirements and financial expectations.

Imbue Sustainability has been involved with the University of Cape Town for a while now, firstly in assisting with developing an auditing procedure to address IEQ (Indoor Environmental Quality) concerns where building occupants requested air conditioning. |

This process undertaken by Imbue and Sow & Reap was to audit the space including the surroundings and propose passive intervention alternatives to airconditioning. This involved assessing where these interventions would place the IEQ in an acceptable comfort band.
Imbue Sustainability is currently undertaking the Green Star New Build, As-Built Rating for the award-winning D School building. The targeted rating for this project is 6-Star and will be submitted for Round 1 imminently.
I have personally known and worked with Simon Penso on various projects over the last ten plus years, including Tool development projects. On a scale of 1 to 10, with 10 being the highest level of client satisfaction, I would confidently rate our experience a 10 out of 10.
