TVOC Monitor- Edificio de oficinas en el parque tecnológico





Project background

The office building is located in a high-tech park, it’s basement is connect with underground garage and kitchen, the office building is needed to to tackle the complex challenge associated with TVOC has risen above the acceptable standard during the working time especially in the morning.

Improvement method


Through the analysis of underground public space, the TVOC comes from the underground kitchen; It is difficult to  isolate complete  by blocking all underground air intakes.

By simultaneous analyzing CO2 concentration, it is judged that the fresh air volume in the building is sufficient.

Adopting the method of reducing exhaust air in time intervals, so that the indoor positive pressure is maintained, making it difficult for underground air to enter the office building. So solve the problem of TVOC risen above the acceptable standard, to help build and maintain a healthy indoor environment.

Monitoring Period: 28th May- 5th June

Monitoring Place: 1st - 4th Floor of the office building Monitoring Product: MSD

Monitoring Gas: TVOC
