Marloes Reinink, Solid Green’s founding director, says, “In light of the many challenges faced by the building industry recently, we are especially proud of this achievement and of our clients for continuing to pursue their green building visions. Over the last decade, we have been honoured to work with trail blazers who have demonstrated both courage and commitment in prioritising sustainability, climate resilience and user wellbeing in the South African property sector.

Legislation and expectations have put pressure on professionals to up their game when delivering green buildings – which in turn has led to teams who are better educated and experienced in this sector. We have been an active part of this process – engaging with clients and teams from the inception of projects; pushing for innovation at every opportunity; and actively advocating for change within the property sector.

Noteworthy Certifications in 2020

Over the last decade, Solid Green has had 84 Green Star, 7 Net Zero, 6 EDGE and 3 LEED projects certified. The Ingress Waterfall certification follows closely on one of the first Net Positive Carbon Level 2: Occupant Emissions (modelled) ratings in South Africa, attained by Hotel Nieu, an off-the-grid boutique hotel in Pretoria that provides upmarket hospitality services to people who care deeply about the appropriate stewarding of resources. The development, founded by Anthony Fitzhenry and Paul Boshoff, is home to older heritage buildings, newer existing buildings and new buildings.

The Ingress Waterfall is Solid Green’s 100th certification milestone.

Hotel Nieu won the Non-standard Awards: Net Zero category in the GBCSA Annual Awards 2020.

At a historic moment in time, just weeks before South Africa went into lockdown, Westend Building C received its 4-Star Green Star SA Design certification. Building C is the third of six buildings to be developed by Abland Property Developers in Westend Office Park, Centurion. This certification, Abland’s seventeenth in collaboration with Solid Green, further demonstrates the developer’s ongoing commitment to sustainable development. Westend Building D, the development’s fourth, is targeting its Green Star Design certification in early 2021.

Pushing the boundaries at every opportunity, Solid Green and Balwin Properties recently achieved a 6-Star Green Star Public & Education Building (PEB) rating for The Reid Lifestyle Centre. As part of a Balwin upmarket lifestyle estate situated close to the Marlboro Gautrain station, the building is also targeting a Net Zero Carbon Level 2 rating – which is possible thanks to the array of energy efficiency measures that have been implemented, together with a 15kWp photovoltaic solar system that is expected to meet 100% of the building energy’s needs.

In addition to its Green Star rating, The Reid Lifestyle Centre is also targeting a Net Zero Carbon Level 2 rating.

And, following an extensive process to regard sustainability as a joint core value, Growthpoint and Serra® Services recently achieved the first Green Star Existing Building Performance (EBP) rating for an industrial building in Gauteng – with a 5-Star certification for a 7400sqm light manufacturing building in Meadowbrook, Germiston.

Driving change in Africa

“Our work on the rest of the continent is growing,” says Chilufya Lombe, director at Solid Green.

There is a large demand for green buildings and precincts in African countries, and we are fortunate to be part of this movement. We have worked on some great projects around legislation and regulations in Nigeria and Ghana. We are also actively involved in education and training – for clients, policy makers and building sector professionals. We have certified buildings in Mauritius, Botswana, Kenya, and Namibia; and are currently working on Green Star and LEED projects in Ghana, Mauritius, Kenya, Namibia, Rwanda, Nigeria, and Zambia.

One of these recent certifications was for the new SABIS® International School – Runda in Nairobi, which achieved a 4-Star Green Star Africa-Kenya PEB (Public & Education Building) v1 Design Rating in April 2020. This was a Green Star regional first, and the school was presented as a case study at the World Green Building Week (21-25 September 2020). As the first Green Star certified school in Kenya, the aim was to positively impact the project’s design and construction costs, asset value, operating costs, workplace productivity and user health.

Fostering an environment for Growth

Among its industry-acknowledged achievements, Solid Green can count nineteen GBCSA Annual Awards over the last ten years. The latest of these was for Hotel Nieu as Winner of the Non-standard Awards: Net Zero category in the GBCSA Annual Awards 2020. Other awards over the years have been achieved under the Established Green Star, Rising Green Star, Highest Rated Building, Best Quality Submission and Net Zero Innovative Project categories; and runner up for company with the Highest Number of Certifications in 2017.

“We put a lot of time and energy into fostering a proactive, inspiring and healthy business culture,” says Reinink, who was named Business Woman of the Year: Entrepreneur at the South African Women in Property Awards 2018.

We take the practice of mentoring young people very seriously, and we are constantly rewarded by their personal and professional growth. We have also committed to providing a healthy work environment for our team, together with lifestyle guidance and ongoing mentorship. We have been amply rewarded with a highly motivated team that consistently delivers exceptional quality work to meet the expectations of our clients.

From early 2021, the team will be continuing its sector-leading work from its new premises in Parkhurst, Johannesburg. “We are incredibly proud that we achieved 6-star Green Star Interior and LEED Commercial Interior Platinum certifications for our offices in Rosebank,” comments Lombe. “We plan on going one step further with our new home in Parkhurst and will be actively pursuing the Living Building Challenge (LBC) Core certification.”

The CORE Green Building Certification is a simple framework that “puts the connection to nature, equity and the need for a building to be loved on even footing with the typical water, energy and materials concerns.” Designed by Activate Architecture, the new offices make use of an existing structure and incorporate additional space under a new roof opening onto a landscaped courtyard garden. The intention is to reuse as much furniture as possible from the old office with some clever design solutions that will make the new spaces functional, adaptable and ergonomically efficient. Natural lighting, glare control, acoustics, multiple workspace options and the inclusion of biophilic elements have been identified as top priorities.

New decade, new chapter

“Climate risks have become part of the mainstream building conversation over the last decade,” Reinink observes.

In planning for future building strategies, health-related risks will join the Resilience conversation – requiring new design and construction methodologies to align with the inevitable changes to regulations that we will see in the coming months and years.

Moving forward, Solid Green intends to meet these demands by continuing to push for innovation in the African construction sector. Projects underway include regenerative developments targeting Net Positive and Living Building Challenge certifications, and growing work on a precinct scale. Reinink adds, “In order for cities to grow in a sustainable manner, developments must take the opportunity to move green design beyond the building scale into the public realm to create places that are both good for the environment and good for people.”

Reinink and Lombe are quick to acknowledge that the company’s achievements have been made possible due to the sector leadership of its clients, the dedication of professional teams, and the ongoing hard work of its staff. Building on the momentum of the last decade, Solid Green will continue its drive for change – towards a more conscious, connected and responsible way of living and doing business.

The post Celebrating 10 Years and 100 Certifications! appeared first on Solid Green Consulting.

Solid Green has been an integral part of South Africa’s green building journey for the past decade. We are immensely proud of every certification we have been involved with – from the smallest victories to the big ‘Firsts’; and we are committed to contributing towards the important advances that the sector is taking to align itself with best practice worldwide.

Developed by Attacq, The Ingress Waterfall’s 20,000sqm of premium-grade commercial space comprises five office buildings ideally located at the entrance to Waterfall City, with visible street access. The buildings, which are located close to a variety of amenities in a pedestrian-friendly, bikeable precinct, are suitable for single occupiers with their own identity or can be divided into multi-tenanted suites.

“Urban resilience and people’s health and wellbeing have been under the spotlight this year,” observes Miron Naidoo, Property Development Manager at the Attacq Group.

With this 4-Star Green Star SA Office Design rating for Phase 1, The Ingress Waterfall has successfully been recognised as Best Practice by implementing standards that speak to these critical considerations, as well as the need to optimise business efficiencies for our clients.

Madi van Wyk, Director at ARC Architects, explains that, in order to create a park within a precinct, the five buildings were placed along the perimeter of the site ensuring a strong street presence while allowing for a larger central courtyard. “The buildings were designed to allow maximum light into the central square and to create a comfortable human scale that does not feel overshadowed by tall building masses,” she says.

A lot of planting was added to further enhance the human scale of the courtyard, with stepped decks to accommodate different seating environments served by the central cafè comprising two repurposed containers.

Van Wyk adds that a façade design was developed for each type of environment faced, which ultimately ties all buildings together. For the North and East facing façades, glazing with spandrels and horizontal louvres was used to address the high sun exposure and glare. Feature elements called for fully glazed facades where dark tinted, double-glazed view panels were used. The Southern facades have similar glazing with spandrels, but with vertical louvres to mitigate the low Western sun that reaches these facades especially during winter months. The Western facades are more solid with punch-out windows or deep-set balconies.

Energy modelling was carried out in the design stages of the buildings and, compared to a notional building model, Greenhouse Gas Emissions have been reduced by 48%. Sub-metering and an effective mechanism for monitoring energy were provided to facilitate ongoing management of energy consumption.

All individual spaces or enclosed spaces are a maximum of 100sqm in size and are individually switched with motion sensors to offer greater flexibility and make it easy to light only occupied areas. The lighting power density for artificial light was also limited to a maximum of 1.50W/sqm per 100 lux to ensure minimal energy consumption. To ensure a high Indoor Environmental Quality, at least 95% of interior finishes specified are low VOC products.

Water meters and an automated monitoring mechanism were put in place to effectively monitor and manage water consumption. Water efficient sanitary fittings were specified and potable water consumption for landscape irrigation was reduced through the use of waterwise landscaping and efficient irrigation systems. This has also resulted in the building’s discharge to sewer being reduced by 50% against an average practice benchmark.

To create a unified brand identity for the precinct, the same material ingredients will be used in different configurations to give each of the five buildings a unique identity, with the lush use of greenery in numerous planters running between and around buildings to ultimately finish off the palette. The absolute quantity of Portland Cement was reduced by 30% across all concrete uses during construction, and reused or post-consumer recycled content steel was utilized in order to reduce the project’s embodied energy and minimise resource depletion.

The steps taken by the developer and professional team to implement sustainable construction and operations at The Ingress Waterfall take into consideration the important balance between environmental concerns, economic feasibility and occupant health and wellbeing.
