scope:

This International Standard gives guidelines related to energy efficiency in buildings as introduced in standard ISO
16813.
The objectives of this standard are to help contractors:
- to assume collection and provision of the useful data that are introduced at different steps of the design
process and to fulfil the definitions of the building as prepared by building designers.
- to assume decisions about building under definition, systems and products and heating/cooling equipment.
This International Standard is applicable to space conditioning equipment and water heating equipment
used in new buildings.
This International Standard applies to new buildings.
It is assumed that the conditions of indoor spaces are maintained within the comfortable range with regard to
temperature, humidity, air quality, acoustics and light.
Systems to be considered to assess energy efficiency of the building are: heating, cooling, lighting, domestic hot
water ventilation and related control or building automation. Building automation system requirements shall be
introduced as they assume the operating conditions and set points to be adequate with the targets values.
