Botswana’s first green star rated building signals a milestone along the green building development path for the country. The new Motswere building, the first addition to Prime Plaza 11 in Gaborone’s CBD, was recently awarded a five star Green Star Africa rating by the Green Building Council South Africa (GBCSA).

The development is owned by PrimeTime Property Holdings and consists of four commercial buildings, each named after a species of local indigenous tree. The building’s name is derived from the Leadwood Combretum trees that still inhabit this piece of land.

Motswere is the first of PrimeTime’s large property portfolio to achieve third party green certification. The building consists of three levels of office space, supporting facilities, two basement parking levels and water wise landscaped gardens. The five-star rating signifies national excellence and requires a standard of innovative green design that goes beyond the basics of green building practises.

A green building responds to local environmental conditions, while also considering global realities such as scarce and expensive energy and resources. Green buildings also respond to the need for healthy indoor spaces for occupants. The green star rating considers energy, water, waste, indoor environment quality, land use and ecology, transport and emissions.

Sustainability features of Motswere include the following:

  • optimal orientation of the building to suit the location;

  • building tuning of the mechanical, electrical, wet services and irrigation services;

  • efficient waste management during the construction phase;

  • on-site recycling facilities;

  • maximising on daylight to lower electrical lighting while providing daylight glare control;

  • use of low volatile organic compound materials indoors;

  • low electric lighting levels, low lighting power density and zoning controls;

  • preferential parking bays for fuel-efficient transport;

  • cyclists facilities for building users and visitors;

  • water efficiency using low flush rate sanitaryware and use of non-potable water in the irrigation system;

  • use of solar PV for reduction of greenhouse gas emissions.
