Building energy efficiency

A well-designed building is functional, comfortable and economical. It meets the needs of its users and adapts to their future stages of life. Energy-efficient solutions may cost slightly more at the procurement stage than conventional solutions, but they save money and the environment during use.

The goals of a construction or renovation project are defined in the preliminary planning and design stage. This stage is important because this is when most of the energy consumption during use is defined in addition to construction costs. Energy efficiency is affected, for example, by the size and shape of the building, insulation, air tightness, the heating system and electricity-saving solutions. A sufficiently long consideration period also enables economically sensible decision making in renovation projects.

The actual energy consumption of a building in use is affected by consumption patterns, by the adaptability of spaces and by the building’s ease of use and maintenance.

‎Building energy efficiency is controlled with legislation and building regulations. In addition to new construction, energy regulations have been extended to renovation and alteration projects requiring a permit.
