Understand the real costs of air handling units throughout their lifecycle and the importance of seeking certified performances for informed decision-making. Don't miss this opportunity to discover how sustainable building practices and energy-efficient HVAC solutions can drive long-term benefits for your business and the environment.

It is obvious that high humidity levels in buildings should be avoided, among others, to reduce the risk of mold. But what about the low levels? It is recommended to reduce pollution sources, ventilate, and keep buildings dry to reach a high level of air quality. But how low is acceptable? Thermal comfort requirements define the range of relative humidity between 30% to 70%, whereas 40% to 60%  is recommended concerning health risk and infection control. EN Standard 16798 defines the level for humidification to be when relative humidity is between 20% and 30%, depending on the building category. What, then, is the right low relative humidity level, and what is the dry air? This short talk will attempt to answer these questions by briefly summarizing the research evidence and discussing different humidification solutions. A tentative acceptable level of low relative humidity will be proposed. Ph.D., Prof. Pawel Wargocki  ISIAQ Fellow, ASHRAE Fellow, REHVA Fellow International Centre for Indoor Environment and Energy Department of Environmental and Resource Engineering, DTU SUSTAIN Technical University of Denmark pawar@dtu.dk

To maintain proper indoor air quality and increase energy efficiency, a demand control ventilation (DCV) system has become a popular solution. While DCV systems offer benefits over constant air volume (CAV) systems, their technique is more complex than used in CAV systems. To guarantee the proper operation of DCV system, attention needs to be paid to check the performance of systems.The results of the carried out study show that only one DCV system performs according to design values in eight public buildings. In all the others, either the airflows were wrong or there was technical fault. However, the indoor air temperatures were within design target values in each space and no complaints about IAQ or thermal comfort were reported by the users.

A HVAC system is installed to provide a comfortable and healthy indoor environment at a low carbon emission. It is not only a question about energy efficiency; but also on how effective a system can use renewable energy when available. Large surface radiant heating and cooling systems are using water temperatures close to the desired room temperature both for heating and cooling. Therefore the system is capable of any type of energy source (district heating/cooling, water pumps, ground source systems) with a high efficiency.

Ventilation based on total volume air distribution in spaces is not always an efficient way to provide occupants with high air for breathing at low-energy consumption. This talk justifies the need for improving the present air distribution design in spaces, and in general the need for a paradigm shift from the design of present ventilation methods to design of advanced ventilation focused on control of supplied air distribution providing each occupant with clean air for breathing. Examples of advanced air distribution solutions in spaces for different use, such as offices, hospital rooms, vehicle compartments, etc. are presented. The potential of controlled air distribution for improving health and comfort of ach occupant at reduced energy consumption is demonstrated. Design criteria are defined and further development is outlined.

Revised EPBD is making an effort to cover indoor environmental quality (IEQ) both in renovation and new buildings. While setting the minimum requirements are on the responsibility of Member States, in many places EPBD requires to do so. There is a focus change especially in renovation to move from avoiding possible negative effects to optimal indoor environmental quality. In new buildings an optimal indoor environmental quality is stressed as enabling measure for good energy performance. Perhaps the most important new requirement is to equip non-residential zero-emission buildings with measuring and control devices for the regulation of indoor air quality at relevant unit level. This and other requirements having direct implications to construction in coming years will be explained in detail in the presentation.

Until 2040, €115 billion will be invested in infrastructure and construction projects in the Stockholm Business Region, shows a new report commissioned by the city of Stockholm. Staffan Ingvarsson, CEO of Stockholm International Fairs, gives a warm welcome to all international guests and provides an insight into key projects for the city and region in the upcoming years.

The art of producing hand-blown flat glass has become a rare craft. In Lamberts glassworks, founded in 1906, the glassmakers have preserved and perfected these traditional production methods. With 70 employees and an export rate of over 75 percent, the medium-sized company from Northern Bavaria is Germany's only manufacturer and at the same time the world market leader. The main products are the hand-blown window glass and more than 5000 different colored glasses. A particular specialty are the two- or multi-colored overlaid glasses, which are complex to produce. Hand-cast Dall and table cathedral glass complete the special offer.

With ambitious sustainabilty goals at the top of the agenda the need for efficient energy solutions in building and construction are a must. The panel features experts in the fields of proptech and contech in Sweden and Europe, an industry that has shown immense growth over the last decade. Nevertheless, there is so much more to be done.

The housing construction industry in Sweden undergoes one of the biggest crises in recent history. At the same time, demand for new housing is huge and reports show that once the pace picks up, projects will be aplenty. How can the industry keep up the pace and what could international companies with know-how from their home markets bring to the table?

Join Dutch circular hero and architect Menno Rubbens together with front figure of Swedens Save The Building "Krama Byggnaden" campaign and one of several projekt leaders of the state-funded research projects "Återhus - att bygga hus av hus" Robin Rushdi Al-Sálehi in an intense discussion about the future of circular urban planning. A future where reuse is the new normal and recycling the last resort. With starting point in their own reuse projects they guide us through todays most prominent and ambitious ideas, compare their different markets and share their experience and the passion for circularity as the core of architecture.
