这栋位于维也纳附近Pressbaum的威卢克斯日光房是奥地利首座碳中性独栋住宅。

建筑师旨在创建一个在能源和生态方面具有高潜力且能够在未来30年内实现零碳足迹。建筑配备48平米单晶光伏屋顶板和9平米太阳能电池板用于水供热和空气热量调节。可以自然通风的开窗不光提供美丽的景观还最大限度实现被动式太阳能，减少夏季和冬季的能源消耗。在这个建筑中，开窗比达到42%。

建筑主材为云衫木。

The Velux Sunlighthouse in Pressbaum near Vienna is the first co²-neutral single-family-house in Austria.

The challenge was to create a house that taps the full potential of the plot on the one hand and to develop an energy and ecology concept that would erase the ecological footprint of the house within the next thirty years on the other hand. What distinguishes this project from many ambitious preceding projects is the aim to combine minimized numerical values for energy efficiency with ambitious architecture in spite of an all but ideal plot.

The energy concept of the building was developed in collaboration with the Danube University of Krems. The building equipment includes a high performing heat pump, 48 m² mono crystalline photovoltaic roof panels, 9 m² thermal solar panels for hot water and a controlled air system with heat recovery. The roof and facade windows were strategically positioned to provide stunning views, to maximize passive solar energy, to enable optimal, natural ventilation during summer time and to minimize the thermal losses during winter as well as to achieve the highest possible factor of daylight. In fact the Sunlighthouse’s total window area is equal to 42% of its floor area. Like the outside planking, the interior fitting is made of spruce wood.

Furthermore each and every material was evaluated in terms of their ecological qualities before their use was authorized. In the end the goal was accomplished. The Sunlighthouse will produce more energy than the construction as well as the usage of the house consumes, which makes it a small “power station” and a beacon project for further conscious and sustainable planning and building.
