If you had to do it again?

We would eliminate the air conditioning system even if we were not complying with the norm, given that the building works bioclimatically on its own and the facilities account for 44% of the environmental impact of the building.

Building users opinion

Very good acceptance of the building.

Energy consumption

• Primary energy need : 29,40 kWhpe/m².year
• Primary energy need for standard building : 38,00 kWhpe/m².year

Calculation method : RD: 47/2007

Breakdown for energy consumption :

- Heating: 3.32
- ACS: 4.14
- Refrigeration: 22.07

More information :

All the energy needed for the building is produced locally. The pine forest of the farm is managed to produce woodchips with which hot water for the Hotel is produced by means of a district heatin system of biomass boilers. And the need for electricity is more than covered by an installation of photovoltaic panels. The building is energetically autonomous.

• Initial consumption : 152,00 kWhpe/m².year

Envelope performance

• Envelope U-Value : 0,49 W.m^-2.K^-1
More information :

the wall facades are built with a thickness of 60 cm, with an average 8 cm layer of lime mortar on the outside, an average 2 cm layer of lime mortar on the inside, and a layer of lime mortar with hemp on the inside.

Users' control system opinion :

The control is carried out centrally as it is a building for public use, also inside the rooms the climate systems are monitored and controlled individually by the guest through CO2 and temperature probes. what maintains the space in conditions marked by the centralization or by the user at all times.

Systems

Heating system :
• Wood boiler
Hot water system :

Ventilation system :
• Double flow heat exchanger

Renewable systems :
• Solar Thermal
• Biomass boiler
• Renewable energy production : 300,00 %
Solutions enhancing nature free gains :

Greenhouse and intake on the south façade, maximization of openings on façades facing south and east in order to maximize direct profits.

GHG emissions

• GHG in use : 5,30 KgCO₂/m²/year

It is carried out with the ITEC database that only has data on the production and construction of the building.

Life Cycle Analysis

Material impact on GHG emissions :

el impacto de los materiales de construcción al margen de las instalaciones supone 325kg/m2

Eco-design material :

An extension of the building is carried out in Tapia lightened with straw, built with earth and straw from the farm itself. The wall is built with calicostrada with an outer crust of lightened lime and hemp mortar that has the function of isolating the outside.

All existing wood is maintained, strengthened, reused and expanded with local wood. the coatings are made of local clay mortar and plaster pavements from Albarracín (also local).

A meticulous design of the interior linings is made so that a conscious selection of materials not only reduce the environmental impact of the intervention but also develop a powerful circular economy project that involves local artisan fabric. In this way, the local craftsmanship is deliberately valued by participating in an emblematic building of this uninhabited area of Teruel.

The methodologies applied in the formulation and design of the earth-bearing walls develop characterization and quality control protocols for the new calicostrada wall system with lightened mortar crusts that edra arquitectura km0 has been developing in order to reintroduce and modernize the systems traditional earthen construction methods to make them more competitive, given that they have a very significant potential to respond to the current climate emergency scenario, both due to their bioclimatic behavior and their ability to influence the reduction of the environmental impact of buildings.

Water management

• Consumption of grey water : 100,00 m³
• Consumption of harvested rainwater : 100,00 m³

The hotel's water comes entirely from two existing wells on the farm, both for hotel use and for irrigation of crops. The water used in the hotel is discharged into a purification system with a biological filter and then infiltrates into an almond-growing field in the upper part of the estate. In other words, it is returned in its entirety to the aquifer, in the same way as irrigation. The system is completely autonomous and closed loop. Consumption is minimal since the water from all uses returns to the aquifer.

Indoor Air quality

The spaces have an interior air renewal system connected directly to the exterior that, through a heat exchanger, prevents losses due to air renewal. These systems are activated by a Co2 probe so that renewal only occurs when the quality of the indoor air requires it; ensuring, on the one hand, the optimal quality of indoor air and minimizing energy losses due to renewal as much as possible.

Comfort

Health & comfort :

A meticulous design has been made to access natural light so that the spaces do not require artificial lighting during the day. All the spaces have interior light management elements so that the user can correct lightning to their liking and depending on the activity they are carrying out.

With respect to the interior materials, work has been done with materials of great thermal inertia that confer optimum hygrothermal behavior, enclosing walls in the bedrooms in the enlarged part and clay mortar renderings in the rest of the rooms, as well as flooring. Albarracín plaster inside the bedrooms. These geo materials are completely natural and do not have any type of additive in their composition. The woods are treated with natural oils or water-based varnishes.

Materials with high thermal inertia give the space thermal stability both in summer and winter, with thermal comfort achievable with minimal heat input in winter. In summer, cold input is not required, although the air conditioning system allows it.

Cross ventilation and recirculation throughout the building have been designed for the hot air produced in the common spaces on the south facade and in the greenhouse on the ground floor. This allows a very important preheating of the interior air that drastically reduces the energy demand of the building. The rooms in the common areas are sectionable so that the manager or user can optimize the use of this heat that is generated in the passive systems depending on the use of the spaces, being able to further optimize the bioclimatic management of the whole.

Calculated indoor CO2 concentration :

según CTE

Calculated thermal comfort : verano 24 ºC, invierno 22ºC

Measured thermal comfort : verano 24 ºC, invierno 22ºC

Acoustic comfort :

The demand for protection against noise is resolved through mass systems both between common areas and bedrooms and between spaces in common areas. The existing masonry walls are maintained and new compacted earth walls are built. The enclosures between bedrooms are made with ceramic partitions and cotton insulation for airborne noise. The floor is also worked with dough and with acoustic insulation made from recycled cotton.

Urban environment

The building is located at the foot of a Mediterranean pine forest on the edge of an area of almond, olive and cereal cultivation. The existing volumetry is maintained and the interventions are compacted in order not to reduce the agricultural land that is developed at the edge of the forest and in the surroundings.

The original farmhouse next to an existing water source is kept and renewes. The new building does not modify the conditions of implementation of the original one and is supplied with both energy and water from the immediate environment. Woodchips that comes from the surrounding forest heat the water necessary to supply the hotel through biomass boilers. Furtehrmore, the photovoltaic installation produces more energy than the establishment requires.
