How to Renovate a Villa - Pay Attention to Indoor Ventilation for Villa Renovation

Since villas have large indoor spaces, when the concentration of volatile organic compounds (VOCs) in the villa is too high, the best method is to increase ventilation. Each of us requires 10 liters of fresh air per minute. However, due to the prolonged use of air conditioning (most modern split-type air conditioners cannot exchange fresh air), and people's common misconception that outdoor air is dirtier, the exchange of fresh indoor air is obviously insufficient. In contrast, Japan has much stricter requirements in this regard. Japanese houses are designed with the mandatory installation of ventilation equipment. However, other regions in Asia generally do not follow this practice, leaving it up to the homeowner whether or not to install such equipment.

In fact, if the indoor air exchange volume is insufficient, not only will there be VOCs, but also the concentrations of carbon dioxide, carbon monoxide, etc., mentioned later will relatively increase. These gases in enclosed spaces can lead to the accumulation of toxins. Therefore, to reduce the harm caused by toxic gases, good ventilation is absolutely necessary.

Take the renovation of someone's office as an example. During the renovation, materials containing VOCs were avoided as much as possible. To maintain indoor air quality, heat exchanger equipment was installed. This equipment not only introduces fresh air and expels toxic gases but also filters out harmful gases from the outside, allowing everyone in the office to breathe fresher air while saving 7% on electricity bills. Despite this, if we don't turn on the heat exchanger after work to allow air exchange between indoors and outdoors, and at the same time keep the windows and doors tightly closed, the concentration of VOCs in the office the next day will still be high. Therefore, maintaining good ventilation equipment is absolutely essential.
