00:00Why do you use green roof?

00:14Green roof is for thermoregulation of the house

00:19because Polish roof is very hot from the sun

00:28and even if there is a good thermal insulation at the bottom,

00:32this leads to heating of the whole house.

00:36The green roof ideally copes with overheating of the house,

00:45and in winter, respectively, there is additional thermal insulation.

00:59We created the Institute for Ecological Conservation

01:02with the mission to promote ecological conservation in Bulgaria

01:07and in the Balkan region as a goal.

01:10Ecological conservation is the ecological way of life,

01:13ecological philosophy,

01:15when we pass on the knowledge that comes from our roots

01:19in a modern, new way,

01:21when we pass it on as we teach,

01:24in this institute we teach as specialists,

01:27people who work in the institute,

01:29as well as people who can change their habits

01:45When you enter such a house,

01:47the feeling is,

01:49if you enter in the summer,

01:51that it is cold inside,

01:53if you enter in the winter,

01:55that it is warm inside,

01:57the reality is that it simply maintains a constant temperature

02:02and does not allow the temperature inside the house

02:05to change as it changes outside.
