Building services engineering (BSE) is a professional engineering discipline that strives to achieve a safe and comfortable indoor environment while minimizing the environmental impact of a building.
The length of study for such a degree is usually 3–4 years for a Bachelor of Engineering (BEng) or Bachelor of Science (BSc) and 4–5 years for a Master of Engineering (MEng).
In the United Kingdom, the Chartered Institution of Building Services Engineers (CIBSE) accredits university degrees in Building Services Engineering.
3D BIM software can have integrated tools for Building Services calculations such sizing ventilation ducts or estimating noise levels.
Another use of 3D/4D BIM is that empowers more informed decision making and better coordination between different disciplines, such as 'collision testing'.
