Sounds for Energy-efficient Buildings

In October 2011, Sounds for Energy-efficient Buildings (S4EeB) began, partially funded by the European Commission under grant no. 284628 S4EeB Sounds for Energy-efficient Buildings. The project is investigating the feasibility of DCV through monitoring sound in buildings to determine the occupancy level. This project is important because energy consumption from buildings make a significant contribution to global CO2 emissions and it is well known that many buildings are heated and lit unnecessarily. Finding a method for only heating, cooling and lighting buildings when required is not an easy task and this project aims to find another method to help with this.
Impacts
S4EeB will investigate a solution to building occupancy detection based on a low-cost audio systems through acoustic sensing. The proposed system works by using precise mathematical optimisation algorithms to decipher the information detected by the microphones.
This would allow exact calculations of lighting and Heating, Ventilation, Air conditioning, Cooling and lighting (HVAC) rate requirements for the whole building snd result in substantial energy savings without reducing comfort for the occupants. It is thought an airport would represent an ideal test site as occupancy is continually fluctuating.
Maremagnum Shopping centre, Barcelona, Spain
As part of a range of measures being undertaken to reduce energy consumption of the Maremagnum shopping centre in Barcelona, the S4EeB project aims to control ventilation and lighting using sounds.
The shopping centre is around 22,000 m2 in floor area.
Principe Pio Shopping Mall, Madrid, Spain
Principe Pio has been a railway station since the 19th Century and since 2004 has had a shopping mall added the railway station is still used as a metro station for the shopping centre and in 2009 39,510,517 passengers passed through.
The shopping centre has a floor area of approximately 32,500m . Fraunhofer, Austria Institute of Technology, Sea and Corio
