New MDA Attorneys to receive a Net Zero Carbon certification

MDA Attorneys / Activate Architecture

MDA Attorney’s new office in Houghton, Johannesburg is one of the first South African building to receive a Net Zero Carbon pilot certification. Designed by Activate Architecture, with Solid Green Consulting as sustainability consultants, the new office space intends to give its users a workplace which both enhances productivity and reduces natural resource depletions.

As a growing practice of construction and technology law specialists, MDA needed to expand its physical footprint and the company acquired a prominent site on the corner of West and Riviera. The existing building was an old home-office conversion which had been gutted and altered over the years. Green principles were a key consideration from the beginning and the opportunity to pursue the Net Zero Carbon certification (together with additional resource efficient features) became apparent as the design process unfolded.

The philosophy and design of MDA’s new office centres around a respect for the natural environment and a clear understanding of our business needs. The project has surpassed our expectations both in terms of its execution and Net Zero certification, and firmly positions us as a thought leader in our sector, in terms of sustainability” says Vaughan Hattingh, director at MDA.

Active Architecture’s approach was to re-orientate the building to allow a view and frontage over the M1 highway, and to add a floor to the building to bring the gross floor area up to 912 square meters.

Michael Magner, director at Activate Architecture explains: “The new addition is a steel structure hovering over the old single storey portion of the project … This design allowed us to create a large open-plan space without adding loads to the structure below, while providing an eye-catching new image for the building. It also enabled a fairly time- and cost-efficient construction process.”

Project architect, Vivien Yun adds: “The office boasts various spaces to work privately and collaboratively, and to interact socially. The intention was to enhance the essence of the 100-year old house while adding a new, modern intervention to reflect MDA as a forward-thinking organization.”

Chilufya Lombe, director at Solid Green explains that, when designing a building for Net Zero, it is crucially important that passive design and energy efficiency features are incorporated before renewable energy systems are even considered: “Due to this design approach, the MDA building is three times more efficient than a standard office building in South Africa. The City of Johannesburg is a signatory to the Net Zero Carbon Buildings Declaration and, as such, is aiming for all new buildings to be Net Zero by 2030. The MDA building has demonstrated that, with foresight and commitment, it is indeed possible to achieve Net Zero.”

Energy efficiency and generation were the underlying principles that will result in the building producing more energy than the base building consumes. “The office areas are designed to be naturally lit for a significant portion of the year thereby reducing reliance on electrical lighting, and high-performance double glazing has been used for the curtain walls” says Lombe. “The passive design principles for this building were optimised so that, even though the building has an air conditioning system, it only has to be used on really hot days. Staff can make use of openable windows for fresh air and comfort”.

Efficient LED lighting is provided throughout most of the building, and the lighting system also features occupancy lighting controls to minimise consumption. And, thanks to the client’s vision, an extensive photovoltaic (PV) system was installed on the roof above the new floor, completely offsetting the building’s electrical needs.”

To further reduce the dependency on natural resources, the building was fitted with a rainwater harvesting system which will be used to offset potable water use in the tenancy. Water-efficient sanitary fittings were installed throughout the building and the site is xeriscaped to reduce the need for irrigation.

From an operational perspective, submetering and monitoring systems for water and energy facilitate ongoing management of the use of these resources; while a waste recycling storage area was provided to encourage the recycling of resources used within the building in order to reduce waste to landfill.

In order to encourage users to adopt alternative means of transportation, the building contains cyclist facilities for both occupants and visitors. Chosen for its central location, the site is within 600 meters walking distance of bus and taxi services and close to several local amenities such as gyms, restaurants and shops.

MDA Attorneys’ new office demonstrates commitment to a more resource efficient way of being, which will ultimately enhance the workplace experience of the building’s occupants and stand the business’ bottom line in good stead during the operational portion of the building’s lifecycle.
