Swegon Air Academy seminars were held in Warsaw and Wroclaw, 4th and 5th of October, with the topic: “Protecting your investments in buildings; focus on the whole building performance”. And following will be Swegon Air Academy seminars in Poznan and Krakow, 16th and 17th of October, with the topic: “Towards better energy performance in buildings in Europe; case studies of benchmarking and passive house technology”. This article is one of the series of articles about Swegon Air Academy seminars in Poland. The series of articles describe the facts about situation in Poland, audience´s expectations and summary of interesting presentations, among others.
This round of Swegon Air Academy seminars were very much focused on delivering extremely useful and practical information in the everyday work of building investors, designers and installers. The case studies of commercial buildings equipped with high efficiency HVAC systems were presented to show the contribution of these buildings towards a huge decrease of energy costs and a short pay-back time.
Here are some facts about Poland:
- In Poland, there are no obligations for building owners to limit CO2 and no incentives; however the general perception in Poland is that the CO2 emission is rather more connected to the political issue imposed by the EU and therefore investors are not really focusing on this topic while building.
- The average office rent rates in Warsaw is 12 – 27 EUR/m2.month, in other big cities 11-16 EUR/m2.month and this puts limit capability on implementing some technologies. In Poland there is no feed-in tariff system so installing PV modules is simply not profitable.
- The average electricity price in Poland is 0.10 – 0.14 EUR/kWh. The prices for energy from gas grid or district heating system are 2.5 to 3 times lower. Relatively high percentage of cities (around 50%) is supplied by heat from the high-temperature district heating systems.
- The important issue in Poland is continuous growth of energy rates
- There are often no utility sub-meters for tenants because it is too expensive for investors and it is easier just to add utility charges to rent. As the result, even although there is a control system, there are no incentives for tenants to save energy.
The audience in Poland is always engaging and the speakers have to always expect complex questions. For example the questions relating to the nearly zero-energy (nZEB) building, Green Buildings versus energy costs and profitability of different HVAC solutions. There were many interesting questions about how much more expensive is nZEB compared to the standard building, what is the payback time and how to attract tenants by Green Building image and low energy cost. Another major issue for discussion was the profitability of different HVAC solutions, i.e. chilled beams, fan coils, free cooling, demand control ventilation (DCV) and variable air volume (VAV), slab cooling and heating.
All this curiosity and questions are important for the Swegon Air Academy events. And the participants could leave with the following comment: “We attended very interesting seminar, the subject were practically addressed to our everyday business issues. Now we know the HVAC system is decisive for total building operational costs. We were presented examples of investments where energy and HVAC installation solutions were decisive for better financial and indoor climate results. Before investment decisions, the deep energy model analysis must be conducted to choose the right HVAC technology. It is also necessary to prepare the life-cycle cost (LCC) analysis of the HVAC installations.”
