Blue Green Engineering specialises in sustainable and efficient building services design. The Blue Green Engineering approach is in 3 stages: • First, unnecessary energy use is eliminated. • Next, necessary energy use is optimised, through energy efficiency measures. • Finally, energy that is needed is derived from sustainable, renewable sources. In the past we have collaborated with many architects and building companies. Our designs have complemented the original design by introducing smart and innovative features into buildings that do not 'cost the earth'. As a result our services have reduced energy usage significantly in many of our projects.
