SOLID GREEN Q What inspired you to move into the green building industry? M arloes: From an early age I had the urge to transform our world into a better place, combining this with my architectural background and through studies and work experience since 2002; I have been focusing on sustainable buildings. C hilufya: I actually got into sustainability quite by accident. I was never really exposed to it during my university years or in the early days of my career. During my first year of work there was a project that required the learning of an element of building design called energy modelling. As the newest employee, I was tasked with the project of Nedbank Phase 2, the first green star rated office block in the country. This is where the green bug bit me and I started to learn more about sustainability in general. I have been exceptionally fortunate to be part of the green building movement in South Africa from its very inception. What are the first steps when Solid Green is appointed to green a building? Marloes: Every project is different. Usually we start with a workshop with the full professional team. We guide them through all the requirements of Green Star credits and establish a strategy to achieve the required star rating (4, 5, or 6). Based on this strategy, we individually consult with the professionals to ensure they understand how the requirements affect their designs and that all requirements get implemented into the tender specifications. At the same time, we start modelling the building in a simulations programme called DesignBuilder. This program accurately estimates the project energy consumption of the building, thermal comfort in different spaces of the building and natural daylight penetration within the building. This simulation can help the team make decisions i.e., “do we need double glazing?”, “can we reduce the HVAC sizing?”, “do we want more daylight into the building?” etc. During design documentation stage of the project, Solid Green collects all the documentation to justify the targeted green star credits in collaboration with the professionals on the team. Based on that, we submit the documentation to the Green Building Council of South Africa (GBCSA) where it gets evaluated; and eventually certification will be awarded. Q Tell us about the Solid Green innovative initiatives? C hilufya: Whilst Green Star certifications are our core work, we also delved into other related industries and work streams. Solid XA is the brand we use for the work we do providing rational assessments for compliance with the national energy code SANS10400XA. We have always seen this as a large potential market that is still under serviced. We set-up a website to try and reach a wider audience where anyone looking to obtain a quote for a rational assessment, upload their drawings, information and project details to receive their rational assessment report and council forms without the need for face to face meetings.
