To reduce and optimize the amount of energy required in our activity, we built the restaurant according to the criteria of bioclimatic architecture, taking into account the predicted levels of activity in both summer and winter.
With more efficient use of resources, we ensure that our activity is more respectful towards nature and we achieve significant savings in terms of costs.
These are the 7 basic principles of bioclimatic architecture that we applied throughout the project:
1. Cross ventilation
The construction is equipped with natural cross ventilation on both façades in order to let air circulate efficiently. In summer, this enables us to enjoy the sea breeze better and, in winter, it allows us to ventilate with small openings in order to avoid condensation in the interior terrace.
Lasal del Varador’s position is extremely good, facing southeast without any building casting a shadow over it.
The adaptation and layout of the spaces are changeable, depending in the time of year.
● Summer: a single space open to the public with a double ventilated roof, which enables us to maintain cool temperatures and avoid using air conditioning.
● Winter: 2 terraces (one covered and enclosed, the other covered but open to the fresh air, facing south, which lets the sun directly in).
3. Solar protection
On the southern façade, portable wooden covers are placed in the summer to protect from the sun.
4. Water saving
The toilets are fitted with a dual flushing system of 6 and 9 litres per flush.
We do not have a water recycling system as, under current legislation, we can only recycle water from the bathroom sinks.
5. Energy saving
In summer, it is not necessary to use air conditioning, thanks to the double roof with a ventilated chamber, which enables us to maintain cooler temperatures in the interior space.
We have double glazing and aluminium seals with thermal bridge breakage, which guarantees great thermal insulation.
We have natural light in all of the restaurants spaces which helps us to reduce energy consumption.
6. Ecological materials:
When selecting materials, we strive to find the best blend of ecology, durability and price. Based on the combination of these three variables, we choose the ideal materials for the construction. They may not all, therefore, be ecological, but the choice is always the most sustainable. It is sometimes preferable to select more durable materials due to the salty condition we are subject to in the seafront environment.
The ecological materials used are as follows:
● The water pipes and drains are made of polypropylene, which helps to avoid the use of PVC, one of the most toxic and polluting materials.
● Thermo-clay bricks.
● Non-halogen electric wiring.
● Wooden beams with FSC sustainability certification.
● Natural court thermal and acoustic insulation fitted.
● Natural mineral paint.
● Environmentally friendly varnishes.
● Fermacell ecological plasterboard panels.
Plants help as a heat control element. In summer, they reduce lateral solar radiation, and they refresh and oxygenate the atmosphere.
