Positive energy buildings represent the next step after the “low energy” and “near zero” standards. They are designed so that, over the course of a year, they produce more energy than they consume, by integrating advanced technologies from the design phase.

The main solutions include photovoltaic panels, heat pumps, smart energy management systems, and high-performance insulation materials. The building thus becomes a small energy producer, capable of delivering surplus energy to the grid or storing it.

In Western Europe, the concept is already applied in residential projects, office buildings, and educational campuses, where operational costs decrease significantly over the long term. The initial investment is higher, but it is offset by lower utility bills and greater energy independence.

In Romania, applicability is increasing, but remains limited by initial costs, the shortage of specialists in integrated design, and bureaucratic procedures for grid connection. However, rising energy prices and European decarbonization policies are accelerating interest in such solutions.

In the medium term, positive energy buildings could become the standard in new developments, transforming the construction sector from a major energy consumer into an active producer.
