Technical Solutions: Solar Heat Water Storage
Background Josef Janni is the creator of a company in Switzerland’s Janni energietechnik. He started the business in the middle of the seventies with making solar collectors. The vision was to create a system that made a building self-sufficient in heating and hot water with only the sun as an energy source. Their solution is […]
“Energy Café” Smart Energy Solutions: Take the Leap – the Right Time is Now
Our society is facing a major challenge to meet our climate goals. How will we achieve our goals? Is there any technological solution available? These are tricky questions that we face and maybe the solution is among the ones and zeros, this was discussed in the Energy Café “smart energy solutions are soon the new […]
Technological Solutions: Ventilation System
This is a brief description of the development of ventilation solutions and pros and cons that can be associated with the different ventilation systems. Natural ventilation Natural ventilation is driven by the thermal forces that occur in the building. This is achieved when the indoor temperature is significantly higher than outside temperature. The supply air […]
Technological Solutions: Wastewater Heat Exchanger
Residential buildings have become more energy efficient when it comes to both the buildings envelope and ventilation, in these areas there is a fairly large range of solutions and well-proven methods on how to save energy in residential buildings. The energy demand for hot water can account for an increasing proportion of the building’s energy […]
Vidzeme Municipalities are Interested in Installing Solar Panels for Electricity Generation
In April this year, Vidzeme Planning Region invited Vidzeme municipalities to applybuildings for solar panel feasibility study. Nine municipalities (Ape, Alūksne, Burtnieki, Cēsis, Gulbene, Kocēni, Naukšēni, Smiltene and Valka) applied at least one of their object. In order to make the necessary calculations, the applied object had to meet several criteria – the building must […]
Seminars in Dalarna about Good Indoor Climate
Today, people are spending more and more time indoors. In the urbanised western world, we spend around 90% of our time in an enclosed space. Studies show that time spent in the home is increasing and can represent up to 19 to 20 hours per day for children and the elderly (1). Thus the importance of […]
How are Prosumers Settled in Poland?
The prosumer is both a producer and a consumer of energy. In Poland, the rules of prosumers functioning are described and regulated in the Act on Renewable Energy Sources. According to the Act, a prosumer in Poland is the owner of a photovoltaic micro-solar system with a capacity of up to 50 kWp. For today, prosumers are divided into enterprises and physical people. Enterprises consume produced energy in real time, the excess can be sold to the network at the price of black energy – without any support. Physical people are encompassed by a preferential method of settlement – the so-called rebate system, known in Europe as a net-metering system. The […]
To Measure is to Know – New Product Released
Most people spend approx. 90% of all time indoors. The quality of the indoor climate has therefore become very important to study. A great number of reports from researchers, institutions as well as reports from ordinary ‘users’ gives a common understanding that improvements are necessary and valuable for both society and individuals. A new study […]
