Energy conservation through building efficiency is globally critical, encompassing zero‑energy passive design, low‑embodied‑energy materials, efficient equipment, and renewable integration. The paper outlines the economic and environmental implications of these four key strategies—passive solar design, low‑embodied‑energy materials, efficient equipment, and integrated renewable systems for heating and electrification.
The energy conservation through energy efficiency in the building has acquired prime importance all over the world. The four main aspects for energy efficiency in a building include first and foremost the nearly zero energy passive building design before actual construction, secondly the usage of low energy building materials during its construction, thirdly use of energy efficient equipments for low operational energy requirement and lastly integration of renewable energy technologies for various applications. These aspects have been discussed along with their economics and environmental impacts briefly in this paper. The first aspect is related to the prior design before construction of a solar passive building techniques adapted all over the world not only for passive heating/cooling but also for daylighting the building. Second is utilizing the low embodied energy building materials for building construction. The third aspect deals with the operational energy conservation using energy efficient equipments in the building. Lastly, the building has to include utility of integrated renewable systems for hot water heating, solar photovoltaic electrification, etc.
