In this post we will discuss some measures or recommendations to influence savings in communities of owners in order to improve efficiency energy at its facilities . when in the building any action is considered to improve its efficiency energy, it is convenient to approach it as a comprehensive action affecting the entire group, always globally to improve its envelope if it were the case or the systems of facilities, but also intervening and improving the own integrity and state of conservation of the same and subsequently apply adequate preventive maintenance on the myself.
The cost of the necessary investment must also be assessed to undertake the improvements and the economic feasibility proposing savings achieved and payback periods achieved with them, although in this case we will only cite some more important measures or recommendations for optimize installation systems.

A point to highlight in the savings of communities of owners is to influence the heating and ACS systems that can reach 55% in community spending of the total. When opting for centralized systems for heating and sanitary hot water it will be convenient to insulate all pipes in the sections from the boiler to the homes, as well as in the areas where they cross common areas or without air conditioning where we can have older losses.
Substitution or change of some of the elements of regulation of the installation that have deteriorated or that are defective such as the burner, the boiler or both, estimating that this action could achieve energy savings of between 7 and 9% or even 16% if they are executed together.
Insulation of non-insulated boilers we will achieve an estimated energy saving of 3%, improving their performance.
Install a control and regulation system for all the installation that allows adapting and optimizing the operation of the installation according to the demand of the building at all times, either sectoring by zones or well using equipment that controls the thermal conditions of each room, the regulation of the water pumps, etc
Replacement of conventional boilers by others of greater performance such as condensing or low temperature. The latter have the advantage that they have fewer losses in distribution pipes than normal boilers.
1.-Adequate mechanisms or equipment must be used to achieve proper management and control of the lighting in common areas and in public areas incidentally so that some of the best functions are the following:
2.-It is recommended to replace the lamps incandescent for those of low consumption since they can reach last up to 10 times longer than normal ones . of this mode it is possible to light efficiently with savings important in electricity consumption, providing even greater Lighting level. As a guide, if we substitute a 100 w incandescent lamp for an efficient 20 w we could achieve total economic savings during your life useful that would reach approximately €64, being at least both a profitable investment.
3.- The use of LED type bulbs or compact fluorescent lamps, especially when we talk about ornamental lighting in common spaces.
4.- In those parts of the building that have many luminaires, it is advisable to sectorize them by zones in order to In this way, manage consumption more rationally, and allowing only those in occupied spaces to be used by the user.
When the water supply network has a lot of amount of lime it will be convenient to install anti-scale devices in the equipment and facilities to allow the correct operation for as long as possible.
Using thermostatic mixer taps with water selector flow rate, a proper mix of cold water and heat without wasting water efficiently. with faucets double-opening mixer so that they have a system with stop to reduce the flow of water up to 50 %.
Use of temperature regulators in the shower can achieve an estimated saving of 5%. Place aerators or flow reducers in the faucets that allow savings in up to 50% water.
The installation of cisterns with flush switch allow to regulate the flow or the amount of water that is lost in each download and allow significant savings in the consumption of water.
It is necessary that on a regular basis carry out a correct general preventive maintenance of the building facilities to allow their proper functioning and avoid deterioration or decrease of their useful life. It is always recommended contracting these services to specialized companies with experience in each installation to guarantee its correct maintenance status.
A recommended option to efficiently manage the energy consumption is by conducting audits that to detect potential weaknesses in order to rectify them adequately and that can also give the users the necessary recommendations in the habits to achieve said objective, so that with such measures, which They will always be individualized to each case, and through a study of costs and benefits obtained can reduce the expense in energy consumption.
