Installation of solar thermal panels for hotel

By 10. October 2016energy, fairpractices


The idea to install solar thermal panels on the roof of the Hôtel du Golf & Spa (Villars) came in 2008 when oil prices soared. Sébastien Angelini, the owner, has always been sensitive to sustainable development but oil prices were a trigger to invest in alternative energies for the hotel.

He first mandated an energy audit and discovered that 70% of the fuel consumption was allocated to water heating and 30% to heating the building. Thermal solar panels were the best alternative to domestic fuels. He installed 80 m2 on the roof, allowing the heating of 4’500 m3 of water.



The first impact is a reduction in fuel consumption of 50% in summer and of 25% in winter. It also led to financial savings on the day-to-day energy consumption. Doing so, Sébastien was reimbursed 100% of the CO2 tax since 2013 on the saved amount of fuel. On a financial point of view this is also worth it!

It’s one of the sustainable practices that gives the hotel the labe « Eco partenaires », which in return helps to inform clients, and allows him to communicate and to be a good example. They now ask their staff to be exemplary and to act at their level in favor of the environment through over good practices.


After conducting an energy audit, they asked an authorization to the Canton de Vaud (which is much easier to get nowadays than before, according to Sébastien). They obtained it quite easily as the solar panels were supposed to be hidden on the roof. They also got some subsidies from the Canton de Vaud that totalised 10% of the investment but it was quite long to get the money. The total financial investment for the 80m2 solar thermal panels installation amounted to CHF 150k, amortized over 7-8 years.

I was born in Geneva and always interested myself in different ways to live and think. I am sure that a more respectful economy can exist without lowering our happiness and that tourism can be more participative and respectful. After my study in Environmental Engineering at EPF Lausanne and ETH Zürich I took part in entreprenarial projects and co-founded the fair traveller project.

    Excellent how to explanation. What I would love to have is some useful links (where the application for reimbursement from the canton is, etc. Paperwork can sometimes be very challenging, so we could make it easier for people to approach it, what do you say?

    A design like yours with a few simple adjustements would really make my blog
