这座房子寻求最大的能源效率，以适应程序、太阳方向、景观和地形的坡度。

This house looks for the maximum energy efficiency adapting itself to the program, the solar orientation, the views and the slope of the terrain.

该项目优化了程序，将其分为四个盒子–厨房、客厅-餐厅、主卧室和客卧–可以一起使用或独立使用。每个盒子都被小心翼翼地放置在地面上，并在其轴线上精确旋转，以找到最适合其使用的景观和方向。卧室面向东方、花园和贝尔维尔城堡；客厅和餐厅面向东南、大海和花园；厨房面向南方和菜园；在客厅上方的阁楼上，露台面向大海的景色，客厅上方的大窗户面向南方，使冬天的阳光能够温暖房子的主要空间，而屋顶的屋檐可以保护夏天的阳光。

The project optimizes the program grouping it in four boxes –kitchen, living-dinning, main bedroom and guest bedrooms- which can be used together or independently. Each box is placed carefully on the ground and rotates on its axis with precision to find the best views and orientation for their use. The bedrooms face the East, the garden and the Bellver Castle; the living and dinning room face South-east, the sea and the garden; the kitchen faces South and the vegetable garden; and in the attic over the living room, the terrace looks towards the view of the sea and its big window over the living room faces South allowing the winter sun to warm the main space of the house while the eaves of the roof protects from the summer sun.

每个盒子都有朝向最佳方向和风景的大开口，在对面的立面上有较小的开口，允许交叉通风并利用这里的东西向微风。南边的开口是凹进去的，以便在冬天让阳光进入，在夏天阻挡阳光，而东边和西边的开口有外部百叶窗。

Each box has large openings towards the best orientations and sights, and smaller openings on the opposite façade allowing cross ventilation and taking advantage of the East-West breezes of the place. The South openings are recessed to let the sun enter in winter and block it in summer, while the East and West openings have exterior shutters.

这座房子是根据PASSIVHAUS标准设计的，以达到最大的能源效率。
为了确保最佳的热量输入，我们进行了严格的信息学和热学研究，在冬季将热量输入最大化，在夏季将热量输入最小化。

The house has been designed according to PASSIVHAUS standards to achieve the maximum energy efficiency.
A rigorous infographic and thermal study has been made to ensure an optimal heat input, maximizing it in winter and minimizing it in summer.

外墙有一个外部保温系统，将保温层厚度增加到15厘米，并严格保护所有接头，以完全避免任何热桥。通过外墙的渗透已经减少到最低限度，而且围护结构的密封性已经最大化，以克服每个空间的增压测试。热交换器确保空气翻新不浪费能源，它被优化为利用淋浴的蒸汽和烹饪产生的热量来转化为暖气。

The façade has an exterior insulation system that increases the insulation thickness up to 15cm and strictly guarding all joints to completely avoid any thermal bridge. The infiltrations through the façade have been reduced to the minimum, and the hermeticism of the enclosure has been maximized to overcome pressurization tests in every space. The heat exchanger ensures air renovation wasting no energy and it is optimized to use the heat generated with showers’ steam and cooking to transform it into heating.

由于这种设计，不需要制冷，这在马洛卡夏季的炎热日子里通常是个问题，而且供暖需求只有11kWh/m2a（在马洛卡这种特点的典型房屋的供暖需求为85至100kWh/m2a），这可以通过一个小型的周边地暖回路解决。加热热水的能量几乎完全来自于太阳能热装置。

Thanks to this design cooling is not necessary, which is typically an issue in the hot days of Mallorca’s summer, and the heating demand is only 11kWh/m2a (a typical house of this characteristics in Mallorca would have a heating demand of 85 to 100 kWh/m2a) which is solved with a small perimeter underfloor heating circuit. The energy to heat the hot water is obtained almost entirely from the solar thermal installation.

坡屋顶有一个收集雨水的系统，其中三个屋顶得到的水用于灌溉和一般使用，而第四个屋顶是 “干净的”，收集的水用于消费。为此，利用房屋和地形坡度之间的空隙，安排了两个独立的水箱，一个40立方米，另一个8立方米。有了这个措施，房子在用水方面是完全自主的。花园包括一块菜地，低维护的本地植被和沿房屋南部的落叶树，以保护夏季的阳光。

The pitched roofs have a system for collecting rainwater, three of them get water for irrigation and general use while the fourth roof is “the clean one” and collects water for consumption. For this purpose two separate tanks, one of 40 m3 and another 8 m3, are arranged taking advantage of the gaps created between the housing and the slope of the terrain. With this measures the house is completely autonomous in terms of water. The garden includes a vegetable patch, low maintenance native vegetation and deciduous trees along the south of the house to protect from the summer sun.

这个项目的建设预算很低，能源维护成本也很低。这是一个促进环境和可持续发展价值的住宅，报告了节约和舒适的情况，而没有引起额外的经济努力。

The project has been made with a low construction budget and a very low cost of energy maintenance. It is a home that promotes environmental and sustainability values, reporting savings and comfort without incurring additional economic effort.

该房屋于去年9月完工，监测其性能一直是重视客户的幸福和满意之外的结果的关键。截至4月，客户完全没有打开暖气，报告说冬季的室内温度（每天测量-白天和晚上）在21ºC至24ºC之间，室外温度在5º至15º。
住在这所房子里的第一个冬天，它没有任何供暖消耗（100%被动式），也没有任何水费（100%雨水）。

The house was finished last September and monitoring its performance has been key to value the results beyond the happiness and satisfaction of the clients. As of April the clients have not turn on the heat at all reporting an interior temperature (measured daily –day and night) for the winter between 21ºC to 24ºC, with exterior temperatures between 5º to 15º.
First winter living in the house and it had ZERO heating consumption (100% passive) and ZERO water expense (100% rainwater).
