Diffuse ventilation in design solutions

Diffuse ventilation offers many advantages, most notably contributing to a significant improvement in indoor air quality and thus individuals’ well-being and health.

Research shows that good indoor air quality is crucial for factors such as concentration and the overall well-being of room occupants. Ventilation and air exchange are important considerations from the project’s inception to ensure optimal integration and a total economic solution.

For ventilation solutions, the Danish company DAMPA utilizes its well-known perforated metal cassettes, embedded with acoustic fabric and suspended in a concealed support system, creating a calm ceiling surface. The support system and ventilation principle ensure that advantageous ventilation is easy to integrate without compromising on the aesthetic desires for the space.

Regarding the combination of diffuse ventilation and DAMPA’s products, Mogens Kjærgaard, Head of RD & Sustainability, explains:

By integrating diffuse ventilation into our ceilings, all the ceiling’s acoustic properties are utilized through the acoustic fabric and perforation pattern without additional installations.

Diffuse Ventilation Principle

Ventilation is often associated with issues like drafts and space-consuming installations, but at DAMPA, Denmark’s leading metal ceiling manufacturer, this is certainly not the case. Here, it signifies tranquility, comfortable air exchange, easy integration, and sustainable materials. DAMPA recommends working with diffuse ventilation:

The diffuse ventilation is based on the principle of creating pressure above the near-to-tight ceiling surface, followed by air supply to the room through the selected perforation pattern in the ceiling surface itself. This way, ventilation is evenly distributed in the room, and drafts are minimized.

A Space-Saving Solution

The unique aspect of diffuse ventilation is its ability to transport air without large traditional duct installations. This means saving on building height by avoiding unnecessary space between floors typically required for traditional ventilation.

 

This saves on building materials and achieves significantly better total economics. Additionally, it is unnecessary to disrupt the ceiling’s serene surface with various outputs because the acoustic perforation in the metal ceiling is utilized.

explains Michael Nykjær, CEO of DAMPA.

This achieves uniform distribution of supply air across the entire ceiling surface at lower pressures without the use of diffusers in the ceiling.”

Easy Integration and Individual Temperature Control

Due to space savings in the solution, indoor air quality can be optimized through other integrations easily hidden and camouflaged in the aesthetic metal ceiling. A valuable combination with diffuse ventilation is DAMPA’s climate ceiling, which is directly integrated into the perforated metal cassettes. The climate ceiling, or cooling ceiling as it is also called, quickly and effectively regulates temperature changes in the room, explains Mogens Kjærgaard:

The climate ceiling cassette responds to each individual’s radiant heat emitted towards the ceiling. This creates a comfortable temperature for each individual without the need for manual temperature regulation and additional ventilation.

The ventilation-free individual temperature control is only possible due to the heat and cold conductive properties of steel and aluminium, thereby creating well-being for all individuals in the room at an individual level.

Building Industry’s Climate Gold Creates Good Indoor Climate

Steel and aluminium also contribute to setting the sustainable and circular agenda, which Michael Nykjær explains:

Due to the metals and our high-quality standards, all our ceiling solutions have a documented lifespan of at least 50 years and can be recycled close to 100%.

 

By recycling the metal, significant resource savings are achieved on material consumption and CO₂ emissions. For example, producing aluminum from recycled material is 10 times less resource-intensive than production with new raw materials.”

This is one of the reasons why DAMPA’s solutions can be recycled close to 100%, and they are produced from large amounts of recycled material.

Functionality and Total-economy in Focus

By choosing DAMPA’s metal ceiling solution, several factors come into play. Partly due to minimal maintenance and the documented lifespan of at least 50 years, functionality and total economics are kept in focus, with a positive impact on the operating budget. It is often seen that when new construction is undertaken, there is a focus on construction costs but not the same focus on operating economics.

Michael Nykjær concludes:

It is through investments in total economics that value-creating solutions are achieved, which can last for many years into the future – and this is where significant long-term savings are achieved.

 

This applies to both the economic budget and, just as importantly, the climate budget.
