1.1.2 Seal air leaks located in all cavities present in the building Description Air leaks can be located in all cavities present in the building. It is not simple to find all points of air infiltration, which are not limited to doors or windows, so sometimes it can be necessary to carry [...]
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 [...]
1.1.7 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), [...]
1.2.1 Turning off air conditioning systems when rooms are empty Description When leaving the room, even if it is for a short time, the air conditioning should be turned off. If possible, turn off the air conditioning 20 minutes before leaving, the air will stay cool during this time and there will [...]
1.2.2 Upgrade and maintain the filters of the HVAC system Description Air filters are used to reduce the amount of dust that reaches the wet coils, keeping the HVAC system clean. Dust can make mold to grow on the wet coils and ducts and can reduce the efficiency of the coils. Clogged [...]
1.1.3 Adjust the temperature of the thermostat properly Description Each degree the thermostat is raised above 21° (recommended set point for winter) implies an unnecessary waste of energy of up to 6-8%. While in summer, each degree below 25° (recommended set point for summer) implies an overconsumption of around 6-8%. [...]
