HVAC lies in the creation of the proper conditions for temperature, humidity and air cleanliness in room environments to fulfil people’s well-being, and is made up of three fundamental aspects: heating, ventilation and air conditioning.

However, sometimes, this well-being is not achieved by applying efficiency and sustainability criteria: windows will not shut properly, heating or air conditioning will be set at too elevated temperatures, proper maintenance will not be applied to certain systems, etc., all of which increases energy costs and results in severe environmental harms.

Then, it is helpful to accomplish a series of advices to achieve efficiency in HVAC and optimize the use of the different systems. The first step is, of course, having efficient equipment available, for the sake of energy savings. However, equipment cannot do much by themselves. It is necessary to count on a control and regulation plan for these systems, pointing out how each element has to function properly, mostly for buildings with integrated HVAC systems, where each owner may have different energy consumption needs. A control system meeting comfort needs of each of them is needed in such cases, always having energy efficiency in mind.

Another advice to consider is keeping devices in good condition. Keeping filters clean and radiators purged are two essential aspects to prevent unnecessary energy consumption.

To keep temperature stable and prevent big changes in temperature, it is important to count on appropriate closure devices. For instance, housing having doors and windows equipped with hermetic closure devices and buildings with automatic doors will make heat losses and cold draughts lower.

Dealing with HVAC, efficiency is essential for saving on the energy bill. A few more or less heating or air conditioning temperature degrees may suppose far more or fewer Euros in your bill.

And as far as efficiency is concerned, making the most of natural resources is essential. Ventilating home during the coolest times of day, taking advantage of sunlight to warm it, using curtains and awnings to cool it or properly insulating walls and roofs are some of the things that can be done.

The use of natural resources is also important as it affects HVAC’s sustainability. If renewable energies are used, buildings energy consumption and CO2 emissions can be reduced up to 30%, as it has been proved after a few studies. Because the fact is that different HVAC technologies with renewable energies are being developed aiming to reduce consumption and the initial investment that these systems entail.

Besides, following these sustainability advices are also beneficial for health. Heating or air conditioning working at more than ten degrees compared with the outside may cause colds, nasal inflammations, headaches or pneumonias. In addition, filters that have not been purged, can make bacteria spread.

For all these reasons, it is important to rely on HVAC systems meeting sustainability and efficiency criteria. Your health, your pocket and the environment will appreciate it.
