Due to its energy efficiency and the approximately 600 square metre photovoltaic system, the embassy building, completed in 2017, has a positive energy balance in its annual operation. The self-supporting photovoltaic roof produces more electricity than is consumed throughout the year in the building. The electricity generated is used entirely on site, so that the embassy building has a high degree of economic efficiency. The consistent use of locally available materials such as laterite and teak and a state-of-the-art architecture also make the building an example for the entire region and provide a very positive response in professional circles.

The users appreciate the pleasant building climate, to which the well thought-out energy concept contributes significantly. The photovoltaic system not only generates energy, but is also part of the ventilation and cooling concept: it provides shade and ensures that the building is bathed in pleasantly cool air. A central ventilation system with small but adequate external air volumes and decentralized cooling registers ensures comfort. The windows are fitted with overcurrent wings, which are also used for night cooling and especially for moisture removal. Overhanging roofs and specially created planting areas ensure natural shading and cooling. The existing stock of trees was also integrated into the planning. A rainwater cistern is used to irrigate the plants.
