Building energy consumption—for air conditioning, lighting, and hot water—is measured by the Building Energy Index (BEI).
Efficiency can be improved by reducing demand through passive design, optimizing usage with active systems, and supplementing with on-site generation.
Since air conditioning accounts for much of this energy use, high-efficiency systems are essential. Yanmar Energy System offers advanced air conditioning solutions that support energy savings.
Buildings used for work and daily life consume energy in many forms—electricity, gas, and heat—for systems such as air conditioning, ventilation, lighting, hot water, elevators, and office equipment.
Achieving carbon neutrality requires minimizing energy consumption within buildings and maximizing on-site energy generation.
The Building Energy Index (BEI) is an indicator of a building’s energy efficiency. It represents the ratio of primary energy consumption in a designed building compared to a standard reference building. A lower BEI indicates higher energy efficiency.
A building is classified as a Net Zero Energy Building (ZEB) if it achieves a BEI of 0.50 or lower, excluding contributions from renewable energy.
Improving energy efficiency in buildings requires the right combination of technologies.
To enhance efficiency, consider the following three steps:
(1) Reduce energy demand through passive design
(2) Use energy efficiently for essential needs with active technologies
(3) Meet those needs with on-site energy generation technologies
Air conditioning accounts for a significant share of building energy use. Adopting high-efficiency systems is therefore essential for energy savings.
Yanmar Energy System offers a variety of high-efficiency air conditioning solutions that support your energy-saving efforts.
