Building Energy Assessments, or Building Energy Rating (BER) assessments, are comprehensive evaluations of a building's energy efficiency and environmental impact. They involve a meticulous analysis of various factors, including the building's design, materials, heating, ventilation, and cooling systems. These assessments not only provide an energy performance rating but also indicate areas of potential energy waste. The findings of a Building Energy Assessment can guide renovations, inform new constructions, and assist in making existing structures more energy-efficient.
