2.1.21 Installation of double windows Description It is a solution to be considered in cold areas, traditionally used in high mountain areas. The installation of another window offers a double protection from the cold climate, creating also an air chamber which works like a greenhouse, forming a layer of warm air and [...]
2.1.22 Convert balconies into galleries Description The system consists in the installation of glazing to close balconies and create, in winter, a closed buffer space which accumulate heat and avoid the contact of external wall surface with cold air. It will work as a greenhouse, so in summer it has to be [...]
2.1.23 Build a greenhouse Description The greenhouse is an element of solar energy collection which consists of large glazed surfaces in the Southern façade which not allow escaping the emitted radiations which have a long wavelength. In large buildings, the greenhouse must be complemented with a ventilation system that properly spreads out [...]
2.1.24 Installation of a green roof Description The vegetation acts as a solar radiation protection in summer, preventing overheating and the fluctuation of the temperature inside the buildings. In winter it would run as an organic insulation that prevents internal energy losses. It is mainly used in flat and slightly sloping roofs. [...]
2.1.25 Use of appropriate materials to increase the thermal inertia of the exposed surfaces to solar radiation Description The thermal inertia is the resistance that a body offers to change its temperature. The envelopes and rooms with significant inertia accumulate a lot of energy. To make a component to contribute with its [...]
2.1.26 Improve insulation in thermal bridge areas Description The thermal bridge is a localised area of the building envelope where the heat-flow is different (usually higher) in comparison with adjacent areas. Usually thermal bridges are located at the end of the windows frame, in the pillars meetings, in the meetings between pillars [...]
2.1.27 Installation of false ceiling to reduce internal height Description The installation of suspended ceiling reduces the volume which has to be heated or cooled helping to lower heating or cooling bills. A reduction of 0.50 metres of internal room height obtained by the installation of false ceiling allows around 1-2% of [...]
2.1.28 Application of an appropriate solar reflectance coating for the roof Description Dark colours absorb the solar radiation more than clear ones which are reflective. The measure consists in the use of dark or clear coatings for the roof depending on the climate conditions. In cold climate to increase heat absorption dark [...]
2.1.29 Application of an appropriate solar reflectance coating for the external walls Description Dark colours absorb the solar radiation more than clear ones which are reflective. The measure consists in the use of dark or clear coatings for the external wall depending on the climate conditions. In cold climate to increase heat [...]
2.1.30 Application of an appropriate solar reflectance coating for the internal walls Description The measure consists in painting internal walls with low-e wall paint, which reflects the heat inside before it is lost through the wall. Otherwise in cooling seasons, the heat is coming through the roof and the walls from the [...]
