1.1.3 Close windows and doors when HVAC systems are operating Description Make sure windows or doors are not open unnecessarily, especially when heating, cooling or air conditioning systems are operating. To ventilate the room it is sufficient to have the window open for 10 minutes. In addition, keep it opened for longer [...]
1.1.4 Manage properly the opening of windows and doors for natural ventilation Description To improve air comfort and reduce the need of HVAC systems use natural ventilation. Open windows of opposite façades to produce cross-ventilation or if the building has a space for vertical circulation or a central courtyard, open windows and/or doors [...]
1.1.6 Correct use of external solar shading Description In cooling seasons users have to block direct solar radiation by closing solar shadings to avoid internal overheating. In others seasons solar shadings should be opened to take advantage of natural light and, in heating seasons also of solar radiation to increase internal thermal [...]
1.1.7 Correct use of internal solar shading Description Internal solar shadings allow the protection of interior space from direct radiation. The user should close the shading when direct solar radiation is entering the building in cooling seasons, while in heating seasons shadings should be opened to permit that solar radiation and natural [...]
1.1.8 Improve insulation of roller shutter box Description It is important to check heat losses from the shutter box because often it is not isolated and it is a significant point of air leakage. The solution consists in installing roller shutter box insulation. Benefits It allows about [...]
1.1.9 Substitution of roller tape guide Description The openings of the roller tape are considered points of air infiltrations and consequently there are thermal bridges. The measure consists in the installation of sealed roller tape guide. Benefits Reduce heat losses and air infiltration and consequently heating energy [...]
1.1.10 Maintenance of wood and aluminium windows frame Description Inspect regularly the windows frame and repaint it if there are cracks which can expose the timber or aluminium to moisture which cause corrosion of aluminium or decomposition of the timber. Lubricate and clean hardware components to avoid a faulty closure. Badly maintained [...]
1.1.11 Adding a low Emissivity (E) window film Description A low E film is an extremely thin layer of metal oxides, in the order of nanometers, which, if it is applied on the glass, provides a capacity of reinforced thermal insulation. The film reflects inward a part of the incident long-wave energy (heating), [...]
1.1.13 Put foil behind radiators to avoid heating the wall Description Silver foil placed in the back of a radiator will reflect heat back into a room rather than letting it uselessly escape through the walls of a house. Benefits The energy savings will not be significant, [...]
1.1.14 Maintenance of room surfaces Description Rooms cleaned at regular intervals or painted in such a way that they have a high reflection coefficient over a long period are the basis for maintaining the high efficiency of the supplied light. Benefits Energy savings Improve comfort [...]
