Question 3

For what key applications do we need energy in buildings?

Answer 3

We need energy in buildings for
Thermal comfort control, energy for controlling heating, cooling and the thermal balance (radiation, transmission etc.)

Indoor air quality management, to achieve that we need energy to control ventilation, filtration, air handling.

Hygenic requirements, domestic hot water and sanitation (Toilet) Energy distribution

Building operation and control, activites to operate, manage and maintain buildings.

Transport systems (Elevators, lifts etc)

Answer 4

Heat gains
- Internal heat gain (Electric suppliances such as TV, kitchen, lamps, people etc)
- Solar heat
- Heating from systems - such as radiators
- Thermal balance between rooms

Heat losses
- Transmissions through windows, facade, ground floor
- Thermal bridges
- Ventilation and infiltration loss

Question 5

What is a smart building?

Answer 5

Smart building is a building that adaptively responds to changing conditions to achieve a good indoor climate and promote health, well-being and productivity of its occupant.

Question 6

What is a data-driven smart building?

A category of smart buildings that adapts after live and historical data from sensors, IoT equipment or AI.

Question 7

Describe the purpose of sustainable building technologies and systems.

Answer 7

They provide smart, useradapted, comfortable and productive indoor enviroments with high energy and resource efficency, high cost-efficency, high user/customer satisfaction and value, and smallest possible enviromental impact.

Give a comfortable and productive indoor enviroment
High energy and recource efficency
High cost efficency
High user/customer satisfaction and value
Smallest possible enviromental impact
