This follows on from yesterday's debate over solar thermal energy storage by thermal buffer either in water or in soil or in phase change materials (MPC) either the 3 at the same time see the subjects (among others):

How to fully heat a building with solar energy?
Heating is the main source of energy expenditure in our country and to heat us, we mainly burn non-renewable fossil fuels such as petroleum products, coal or natural gas. The combustion of these products is problematic because it is a source of atmospheric pollutants and in particular of CO2 and methane, gases which contribute to global warming. However, there are alternative solutions which make it possible to dispense completely with fossil fuels, this is particularly the case of the particularly innovative system proposed by the company Jenni.
Building during construction. We can see very well the tank which allows to store the water heated by the solar panels.
Built in 2007 in Oberburg, a municipality in the Canton of Bern, the Jenni building is the first building to be fully heated with solar energy. It was imagined by Josef Jenni, one of the pioneers of solar energy in Switzerland and includes 8 apartments. To be able to do without fossil energy and be autonomous, this building has been very well insulated and the builders have developed a system that stores energy in summer or when the weather is good. This heat is then restored on the coldest and sunless days in winter.
* The key elements of construction
The building is labeled Minergie P, this means that it meets an even more demanding standard than that of the Minergie Label! To achieve this performance, the building is insulated from the outside, it has dual-flow ventilation which limits the energy losses linked to ventilation and also has double-glazed wooden windows which reduce heat loss and allow dwellings to benefit from passive sunshine.
* Heating and domestic hot water
The 276 m2 of solar panels heat the water of a tank of more than 200 liters. This tank accumulates heat during periods of significant radiation (summer, etc.) and releases hot water as needed (heating, sanitary use). It makes the building energy independent for these uses. The first beneficiaries of this system are the tenants who have not paid any heating and hot water charges since they moved in!
"Oil of Emmental": in the land of Emmental, it's not just cheese, there are also very good ideas
The solar building was imagined by Jenni, one of the main promoters of the “Oil of emmental” project. This project aims to make this territory more self-sufficient in energy. Indeed, this region must currently import nearly 90% of its energy needs which has an economic cost (160 Million Francs per year) and ecological (greenhouse gas emissions). However, according to current knowledge, the Emmental region could be supplied 80% thanks to local energies (wood, anaerobic digestion, solar ...) with the key local jobs and an energy supply largely neutral in CO2 .
