Boogertman + Partners has recently moved its Johannesburg operations to Main Straight Office Park at 392 Main Road in Bryanston. Block C, owned by The Main Straight (Pty) Ltd, developed by RPP Developments and Enigma Group, was specifically designed for and by Boogertman + Partners and green building features were incorporated from the start earning the building a 4-Star Green Star Design Office v1.1 rating and 5-Star Interiors v1 rating.
Solid Green was the sustainability consultant on the certification, with Jessé Hamman the Green Star accredited professional on the project. “The developer sought not only to provide the tenant with lower utility costs, but tenant and occupant wellbeing was also of top priority – a philosophy that is being carried through to the project’s interior fitout,” she states.
As part of the strategy to reduce the overall energy consumption of the building, lighting power density levels were designed to be 40-50% less than the prescribed standard, while still maintaining lighting levels above the Occupational Health and Safety (OH&S) requirements so that sufficient lighting is provided for specific tasks without wasting electricity. All individual or enclosed spaces are less than 100m2 in size, and are individually switched. This, together with light intensity and motion detector sensors, make it easy to light only occupied areas.
All direct and indirect office lighting is low energy LED lighting, equipped with electronic drivers, and are Occupancy sensor controlled.
To better understand and manage building systems, and to assess opportunities for water and energy savings, sub-metering of lighting, power and all substantive energy use items greater than 100kVA is provided, along with an effective mechanism for monitoring energy consumption. An integrated monitoring system records and logs all energy and water usage within the building, and this data can be displayed in real time.
Reducing water usage
An air-cooled HVAC system has been employed in the building consisting of a high efficiency variable refrigerant volume (VRV) heat recovery system as well as a hybrid package system, which in turn comprises an air handling unit coupled to VRV condensing units. These systems do not use any water during operation.
In addition, sanitary fittings that reduce predicted potable water consumption were installed, while water meters and an automated monitoring mechanism monitor and manage consumption. These measures have resulted in the building’s outflow from occupant usage being reduced by 50% against an average practice benchmark.
In addition, a waste recycling storage area encourage recycling of paper and cardboard; plastic, glass and cans; metals; and general waste to reduce waste going to landfill.
Inside, the building includes a mix of private and collaborative workspace and facilitates employee wellness by incorporating spaces to interact socially, such as a canteen and a crèche. It is also situated within walking distance of both the Gautrain and the Metro bus stops, and is close to the Post House Centre, providing access to retail outlets and restaurants.
