Solid Green Consulting

What Solid Green Consulting does

Solid Green Consulting CC is a South African sustainability consultancy founded in 2010 by Marloes Reinink, headquartered in Johannesburg (Parkhurst) with a second office opened in Cape Town in March 2025. The firm advises property developers, building owners, and corporate tenants on green building certification and high-performance sustainable design, with a track record of 300+ certified projects across South Africa and other African markets including Zimbabwe, Zambia, Namibia, Kenya, and Mauritius. Core service lines cover Green Star SA, EDGE, Net Zero Carbon/Water/Waste/Ecology, and Living Building Challenge certifications, supported by energy and water modeling and simulation (using tools such as DesignBuilder) and Existing Building Performance assessments.

The company has developed two proprietary digital platforms: Solid XA, a web application for SANS 10400-XA Rational Path to Compliance assessments with instant quoting, and Solid Insight, a data and resource management platform connecting smart meters to building management systems for live energy, water, and carbon emissions reporting. Solid Green also hosts and delivers the Design for Greater Efficiency (DfGE) training course developed by the IFC/World Bank Group, providing 3.0 CPD credits to building professionals. The firm is a B-BBEE Level 2 Qualified Small Enterprise and a member of both the Green Building Council South Africa and the US Green Building Council, with staff holding Green Star Accredited Professional and EDGE Expert credentials.

The business model is primarily project-based professional services consulting, supplemented by training course fees (R4,500 per DfGE participant) and limited software tooling revenue. Client base spans South African enterprise real estate (Growthpoint, Redefine, Balwin, Liberty Two Degrees, Intaprop), banking (Old Mutual, Nedbank, First Capital Bank), healthcare (Discovery), industrial (DSM-Firmenich), legal (ENSafrica), and affordable housing (Madulammoho), with marquee engagements including Africa's first Living Building Challenge project, first Net Zero Water (Measured) certification, and multiple 6-Star Green Star ratings. Marketing is sales-led, driven by thought leadership content, industry awards, and GBCSA participation rather than paid acquisition. The company is founder-owned with no disclosed external funding.
