Architectural description

At the beggining there was a non-exclusive building easily accessible for the development of the work. The structural system of the building is based on solid slabs, beams, columns and basement walls of reinforced concrete, the facade is solved by a ventilated facade system with aluminum composite panel on metal frame anchored to the slab edges and factory brick. This system allows to dismantle the facade panels in a simple way both for their replacement, and to access the hidden installations behind it .. For the covers, a landscaping system has been used in combination with transited covers so that the heat island effect can be reduced: -Terrace garden as a continuation of the work surfaces. For this, the landscaped surface rises to a height of 75 cm inside to match the height of the work surfaces. -Walkable Terrace with concrete pavement and polished surface finish. The ceilings are left bare with facilities views whenever possible. In offices and meeting rooms a false ceiling plasterboard will help to improve the acoustic performance. - Workspaces are design to have the highest level of natural light and views to the outside, to improve working conditions comfort of building users. To do so, exterior carpentry with large gaps for the use of natural lighting and enhancement of the views are configured. Carpentries are selected with the lower profile section allowing large glazed areas to the outside. All glasses have to use acoustic behavior and in the required areas, solar control and low emissivity. It is intended to highlight these gaps by frames made with the same facade material in black as carpentry and surpassing them the front line about 10 cm. The windows inner beams are placed to mark the depth. The interior woodwork is white lacquered wood with stainless steel handles with satin finish. The floors are concrete on insulation layer and slab of reinforced concrete. In areas of multiple uses and offices a system of underfloor heating-cooling fan-coils reinforced available. In the operational area the accessibility to electrical and telecommunications installations are to be highlighted, housed in gutters on the pavement. For interior partitions, double or single partitions plasterboard on galvanized steel profiles with mineral wool insulation, and transparent screens anodized aluminum profile with laminar double glazing, which presents an excellent acoustic behavior are used.

They have been carefully chosen all material considering the impact this could have on the building and its contribution to sustainability. Disashop intends, with the use of best practices, get your new home is an exemplary building, respecting the environment and offering the best possible comfort to all its users. The subsystems are designed carefully so that offering the best guarantees of comfort and energy efficiency to each of the areas they serve, so we have several subsystems:  heated areas only with underfloor  areas with cooling underfloor and inductors only cold  areas with floor heating-cooling and cooling only fan coil units  areas with hot and cold inducers  Zone CPD with cooling only fan coil all powered by two geothermal heat pumps and air-cooling support CPD water to keep constantly running. As for the air renewal system is MENERGA unit has a model Adsolair SOLVENT 58 13 01 with a nominal flow rate of 9,800 m³ / h. It is a treatment unit air with heat recovery dual body system of indirect adiabatic cooling, refrigerant circuit reinforced incorporated and constant pressure regulation in the drive for operation of the equipment with dampers and regulation quality air return. Outdoor air ventilation in the building properly introduce filtering, for this the air handling unit is equipped with a set of filters for return air and outside air. The filter is Class F6 for return air and outdoor class and compact F8 for supply air type. Fan coil type indoor units also are equipped with their own section of filters in the drive.

    The photovoltaic installation is designed on a voluntary basis, in order to improve the overall energy efficiency of the building and give the building a sustainable basis that will allow aspire to obtain an environmental certification. This is a photovoltaic system in solitary consumption, with a peak power installed such that its production is easily absorbed by the consumption of the building without having to resort to storage batteries. The solar plant has a designed installed capacity of 23.04 kWp photovoltaic modules, using 96 modules IBC brand model PolySol 240 TX, 240 Wp each.

Smart Building

    The building has a comprehensive control system specifically designed by SAUTER according to the characteristics present in the system. This control system has so web module that allows remote management of it

    The building has automatic controls needed to keep local design conditions provided for adjusting energy consumption to variations in the thermal load. The facilities in the different areas are equipped with isolation valves to knock out each without affecting the rest. The variation in water temperature depending on the outside conditions will be made through the same heat pumps. Through mixing valves commanded by the general regulation system, it is regulated to turn the flow temperature from the accumulators of inertia, in the event that the vessel temperature of inertia is greater than the flow temperature set by the conditions inside the building. • Control of room temperature in the premises where teams have been arranged fan coil type: Finally, as a summary, the main control systems that will be part of the thermal installations of the building in question are described. It is done with separate thermostats which control the operation of the units so that delivered power varying with a certain speed air propulsion also selected by the user. • Control soil heating-cooling. The floor heating is controlled by thermostats cold / heat acting on the electrothermal heads of each circuit. It has a probe immersed in the distribution pipe to the underfloor heating and temperature setpoint for water heating drive mode is at 35 ° C. • Control of room temperature in air-conditioned premises with induction systems. It is done with separate thermostats which control operation of the units both cold and heat so as to deliver more or less power depending on comfort conditions indicated for each zone, making regulation through valves each the teams. In the common workspace zoning is done so that the outside areas (close to front) of the interior are distinguished. • As previously commented it features a comprehensive control system specifically designed by SAUTER according to the characteristics present in the building installation. This control system has a web module that allows remote management form thereof, as well as collecting performance records and historical display.

GHG emissions

Water management

  • 222,65 m3
  • The only water consumption presented in the building is the sanitary water and process water for filling air-conditioning systems. Other consumption and irrigation destined to covers and plots do not apply because the implemented system is sedum type and this latitudes this species don't need irrigation.

Indoor Air quality

    The building has a ventilation unit that is responsible for ensuring sufficient flow of outside air, preventing the formation of high concentrations of pollutants in different premises where any human activity is performed. According to this, areas corresponding to offices, common work area, meeting rooms, changing rooms, toilets and rest areas are mechanically ventilated. Since the building will aim for LEED environmental certification, ventilation flows, in addition to the provisions of the RITE adapt, where necessary, to meet the minimum requirements of sections 4 to 7 of ASHRAE 62.1-2007 standard the (Ventilation for Acceptable Indoor Air Quality) and especially the renewal minimum flows indicated in the table 6-1. Minimum Ventilation Rates in Breathing zone. To ensure indoor air quality a ventilation unit capable of recovering thermal energy from the indoor air at the time of extraction is selected. It is a unit of the firm MENERGA, type Adsolair SOLVENT 58 13 01. This unit air treatment has a specially designed double exchanger through which air flows countercurrent cross, in a sense the outside air and the another return air, not getting itself to mix at any time. This allows also a high heat recovery sensible efficiency greater than 75%, the stale air inside is recirculated not at any time, whatever its nature.


    The interior design conditions operating temperature and relative humidity are set based on the metabolic activity of people, their state of dress and the estimated percentage of dissatisfied, as indicated by the RITE in its IT . Given that the people who inhabit the building will have a mainly sedentary metabolic activity, since most of its surface is dedicated to offices, is expected to internal working conditions of the facility in winter will be between 21 and 23 ° C temperature and 40/50% relative humidity, and in summer between 23 and 25 ° C temperature and 45/60% relative humidity. As it mentioned above have chosen the most suitable method for heating premises by use of the same, being mainly used systems floor heating and diffusion induction. Has been adopted as a final solution the underfloor considered the most suitable method for heating large volumes, due to the temperature distribution offering in the occupied space, minimizing losses by not creating air pockets in the ceiling as with other heating systems. Induction systems have been chosen for their high performance, fast response and low power consumption and maintenance lacking fans. These features must be added the low noise and nuisance to the end user streams.
