Consultants

Alexandra Gower

Alexandra Gower

Alexandra Gower is a senior consultant at The Green House. Alexandra holds undergraduate and Honours degrees in Earth Science from Stellenbosch University and an MSc in Sustainable Development and Climate Change from UCT. She began working at The Green House during an 18-month internship as part of the WWF-SA’s Environmental Leaders Programme, before transitioning to a permanent position. Her work at The Green House includes energy and emissions modelling, carbon footprinting and verification, greenhouse gas inventory reporting, low emissions development and life-cycle assessment research. As an expert Analytica modeler, she has been involved in projects relating to climate change mitigation in South Africa, including quantitative modelling of emissions projections across all sectors of the economy and scenario modelling. In addition, Alexandra has experience in training and developing Analytica training material.

Bianca van Zyl

Bianca van Zyl

Bianca has an undergraduate and master’s degree in Industrial Engineering from Stellenbosch University. During her studies, she specialised in agent-based simulation modelling, operations research, data science and analysis, and machine learning. Her final-year project involved modelling the spread of rabies in South African informal settlements, while for her master’s she applied machine learning approaches to the task of sentiment analysis in the field of natural language processing. Having explored a diverse range of fields, she decided to pursue a career in sustainability. At The Green House, Bianca provides research, modelling, and data analysis support for life cycle assessments and carbon footprinting projects.

Matthew Burke

Matthew Burke is a senior consultant at The Green House. He has an undergraduate and MSc degree in Chemical Engineering from the University of Cape Town. His Master’s research was in the bioengineering field and included the design of algal reactors to improve growth while ensuring low energy usage. After completing his studies Matthew worked as a research assistant in the Centre for Bioprocess Engineering Research (CeBER) at UCT focusing on the production of bioenergy through anaerobic digestion and wastewater remediation. Since joining The Green House he has specialised in life cycle assessment (LCA) and carbon footprinting, along with combining the two to help companies fully quantify their value chain (scope 1, 2 & 3) carbon footprint. Projects have also involved LCA dataset compilation, Greenhouse Gas (GHG) inventory reporting, survey design and analysis, landscape approach mitigation planning, national material flow analyses and conducting various training courses on LCA and GHG reporting.

Matthew has recently managed life cycle assessment, carbon footprinting and mitigation measure identification and target setting projects for various corporate clients. His LCA expertise spans a number of sectors, including the agriculture, waste, food, plastics and packaging sectors.
