Investigation and field measurements of ventilation in buildings.

Purpose

As an independent part assist users and/or property owner in investigating, evaluating and, if necessary, making limited field measurements of the ventilation function in their buildings, usually in connections with them being uncertain or having complaints about the ventilation function. RISE does not carry out adjustments or routine ventilation checks, such as OVK, but refers such assignments to consultants who routinely perform this type of service.

Through RISE's accumulated and long-standing experience in the ventilation area (theoretical/academic as well as from laboratory tests and field assignments) we have a broad and deep knowledge of how ventilation systems work and what can be wrong and cause problems.

Many problems with indoor environment and/or high energy use are due to faults and deficiencies in the function of ventilation. There may be errors in the design as well as during the installation or in the operation and control of the system.

 Many times, users or operating staff have not received enough information and knowledge about how the system works and how it should be managed. 

Method

The customer's need is identified via telephone and/or e-mail. Then an indication of price and delivery time is first given. If the customer is still interested, we may request additional documentation in the form of drawings, protocols, etc. before we write a formal quote. Since a fixed price is often difficult to give, the work is usually offered on a current hourly rate up to a maximum price. 

If the quotation is accepted, a time for ocular inspection and eventual measurements is then determined in consultation with the customer. Often, an ocular examination is enough to give a statement on the function of the ventilation and any suggestions for measures. In some cases, more detailed measurements may need to be performed, either by RISE or by another actor.

Deliveries

Usually, the customer receives a report that describes the background, implementation and results. For shorter projects, simplified reporting can be done via e-mail, possibly with attachments in the form of pictures, tables and/or diagrams.
