Alibuilding incorporates in its promotion of San Juan smart glass and aerothermal technology to generate energy from the ambient air temperature

Alicante, August 10.- he promoter Alibuilding will install in its development that is running in San Juan Playa (Alicante) aerothermal systems with the capacity to generate energy from the ambient air temperature. This technology, the installation of smart glass in windows, underfloor heating-cooling and technological insulation on facades and roofs, makes the San Juan Beach development one of the highly sustainable buildings in the city with energy saving capacity in heating, cooling and water. 50% health care, as well as reducing the carbon footprint generated by the use of the home.

Aerothermal technology systems achieve levels higher than 78% of the energy required by the services they supply thanks to the energy extracted from the ambient air, which it transforms into cold or hot air, both for heating water and for cooling rooms. . This technology that produces energy without the combustion of fossil material, and therefore without the emission of polluting gases, will be installed in the development of 104 homes of  San Juan Beach in Alicante.

San Juan Beach will have technology to produce four kilowatts for each kilowatt consumed, due to a system that allows it to absorb energy from the outside air, as well as recovering the house's own heat for later consumption.

In addition, for the air conditioning of the rooms, this system is complemented with grilles that control the air flow electronically, which allow the amount of hot or cold air that comes out through the grilles to be regulated in the home itself depending on how many users are used. found in that room, increasing the power of the air through the vents in some rooms and limiting the air outlet in others when they are not used.

Smart glass, underfloor heating-cooling and reinforced surround

The general director of Alibuilding, José Antonio Izquierdo, explained that it is also the first time that underfloor heating-cooling is installed in a general way in a residential building, until now only used in high-end single-family homes.

"The underfloor heating-cooling has never been used generically before in the construction of houses, only sometimes in luxury single-family homes, as it is a very high technology of great energy efficiency", he commented. The system consists of the installation of a network of ducts under the pavement through which hot water can pass in winter and cold water in summer, which generates an average temperature throughout the house.

In the case of San Juan Beach, the windows have been designed with carpentry with thermal break and selective glass panes, that is, low-emissivity glass with solar control, called “smart glass”. The thermal break carpentry is composed of a double glass that does not have contact between them, generating an intermediate space that allows temperature control. This system, plus the installation of smart glass, reinforce the environmental aspect of the construction, with very important energy savings.

Both elements make that in summer they reflect to the outside a large part of the incident solar radiation and minimize the energy losses of the indoor air conditioning; while in winter they act the opposite, reduce the passage of cold from outside and maintain the interior temperature of the house.  According to studies, these qualities maximize comfort, reduce energy losses in the house by up to 44% and greatly save the daily cost of house bills, reducing consumption by up to 50%.

To all this, the design of the Chamizo Arquitectos office has reinforced the building envelope, façade and roof, with the aim of reducing energy loss as much as possible. Izquierdo explained that "the façade is designed taking into account the orientation of the building: locating the living rooms and main bedrooms with the largest windows to the east, which coincides with the view towards the sea."  In the case of San Juan Beach, the facades will have double insulation with a total thickness of 10 centimeters of insulating materials, while the roof will have eight centimeters of extruded polystyrene as insulation of the highest quality.
