Project description:

The energy efficiency of building is one of the biggest problems in Lithuanian energy and construction industries, because the largest part of existing buildings is not energy efficient. To improve energy efficiency buildings are renovated. Installation possibilities of renewable energy sources (RES) are often considered during preparation of renovation. The application of solar energy technology is rapidly developing, but the efficiency of the usage can be limited by orientation and geometry and effect of contiguity – nearby structures and vegetation. The technology, capable quickly and conveniently evaluate the structural parameters of the specific building and the influence of nearby objects on technological solutions for energy supply, could useful tool for renovation project designers; it could be applied in evaluation of habitable territories during preparation of municipalities specific plans for energy supply. During this project the accurate 3D model of specific area with known dimensions, orientation, coordinates of the objects in the model, will be reconstructed by photogrammetry from large amount of photo fixations (photographs with positioning data). Because 3D model recreates real environment it allows to simulate sunlight during different time of the day in every season.
