In my previous column, we explored the various ways building information modeling (BIM) software has impacted sustainable architecture. Expanding on the theme of sustainability, this month's column examines a new trend in sustainability software called building energy modeling (BEM).

BEM is a type of software that typically integrates with BIM tools to further improve energy analysis and management. BEM programs offer entire building energy simulations that engineers, architects, and researchers use to model energy consumption-such as heating, cooling, ventilation, lighting, and plug and process loads-as well as water use in buildings.

Although building energy modeling is currently a niche software market, at G2 we believe it will rise in popularity due to its ability to improve sustainability, provide a high ROI, and ultimately create better work environments for the public.
