User Research

Observation & Interview

Observations and interviews with pub owners are conducted in three bars in Delft in order to review different habits, features and methods that might have not been noted or stated by the manager.

• Pub owners care more about the customers than sustainability.

• Staffs can forget to put down/off the heating and lights etc.

• The pubs prefer light bulbs over LED for cosy atmosphere.

• The most energy consuming parts are for kitchen uses.

• A lot of pubs have candles on the tables for good atmosphere.

• When there are more customers in the pub, less heating needed.

• Most pubs have an system to control temperature and lighting.

Product Prototype

An Arduino prototype is made to simulate the measurement of light intensity. In the real product, it should work on both lighting and heating, so only the former will be shown in this prototype.
