Conceptual design

At the conceptual design stage, a skilled modeler might create a simplified model of the building to test the impact of location, building’s orientation & massing on annual energy saving (%).

The model might not be completely accurate, but is perfectly adequate for comparing alternate scenarios. Researchers found that focusing on the above values at the early stages of a project can provide significant environmental and social benefits without any incremental costs.

For example: Simply orienting a building to optimize windows and passive solar heat gain may allow developers and architects to design for lower energy consumption and sustain those values as well as create a day-lit space, which can improve comfort level and increase productivity for employees without adding any additional construction costs.
