In February 2011, the integrated childcare centre Solhuset in Hørsholm opened its doors to nearly 100 children and 30 adults. They now enjoy everyday life in a healthy environment with plenty of daylight and fresh air.Solhuset is the most climate friendly daycare centre in Denmark. It is a unique building, self-sufficient with energy, and built as an Active House. This makes Solhuset very interesting not least for professionals within climate, energy and environment.
目标与愿景 Aim and vision
Childcare centres and schools have a particular need for a good and healthy indoor climate as it strengthens well- being and learning capacity as well as reduces the risk of diseases.
The vision for Solhuset (The Sunhouse) was to set new standards for future sustainable childcare centres. It rests on the Active House principles of build- ings that give more than they take to the children, adults, environment, and surroundings. Solhuset is show- ing the way; it has the framework for a healthy indoor climate where children learn to live in harmony with nature and without negative impact on the environment.
此项目由VKR Holding A/S（威卢克斯集团母公司）及其战略合作伙伴霍斯霍尔姆自治市政府和ions Børnehuse共同研发设计，并由Hellerup Byg A/S、Christensen & coarkitekter a/s以及Rambøll A/S三家建筑公司倾力打造。其的战略合作伙伴希望，这座“太阳堡”能够成为未来可持续发展的儿童保育中心，在这里，孩子们可以学习如何与自然和环境进行良性的互动。
Solhuset was developed in a strategic partnership between Hørsholm Municipality, VKR Holding A/S and Lions Børnehuse, and built by Hellerup Byg A/S in co-operation with Christensen & CO arkitekter a/s and Rambøll A/S. VELUX A/S, VELFAC A/S, SONNENKRAFT, WindowMaster A/S and SUPERWOOD A/S supplied the materials: roof and facade windows, solar thermal and geothermal heat systems, intelligent control system, natural and mechanical ventilation, and cladding.
The partners want Solhuset to be a vi- sion for future childcare centres, where children learn to live in interaction with nature without having a negative impact on the environment.
Solhuset shows the path to buildings
of the future by:
contributing to reducing the use of fossil fuels,
providing a healthy and comfortable indoor climate,
contributing positively to the environment and its surroundings.
可持续建筑 Active House
Solhuset was designed and built accord- ing to the Active House principles − a vision of buildings that give more than they take by creating healthy and comfortable lives for their occupants with no negative impact on the environment.
The Active House principles set the frame- work for design and renovation of build- ings that contribute positively to human health and well-being by focusing on indoor and outdoor environments and renewable energy. Such buildings are evaluated by the inter- action between three parameters:
Environment: an Active House interacts positively with the environment through an optimised relationship with its local context, conscious use of resources, and overall environmental impact through- out its life cycle.
Indoor climate: an Active House creates healthier and more comfortable indoor conditions for its occupants and ensures a generous supply of daylight and fresh air. The materials used have a positive impact on comfort and indoor climate.
Energy: an Active House is energy-effi- cient and all energy needed is supplied by renewable energy sources integrated in the building or by the nearby collec- tive energy system and electricity grid.

为儿童量身打造的可持续建筑 An Active House for children
The new childcare centre Solhuset is an exciting, lively, and bright building, where both children and adults feel at ease.
Solhuset is laid out as a small village with streets, lanes, small squares and niches, and is divided into three zones: an arrival zone; a small children’s zone with access to group rooms, an outdoor area and an open-air shelter; and a large children’s zone with access to group rooms and the outdoor area. Common exercise rooms and eating facilities are placed in the middle of the house for easy access.
Solhuset has a healthy and comfortable indoor climate with plenty of daylight and fresh air.
It has high-ceilinged rooms and strategically-placed windows to ensure optimum use of daylight. The sloping roof, with roof windows that open and close auto- matically, creates varied ceiling heights for good air circulation in the rooms.

Intelligently controlled sun screening and window opening make the house flexible, allowing the flow of daylight and fresh air to adapt continuously to the weather conditions outside and the needs indoors. Solhuset is built of sound materials that have minimal impact on the indoor climate. Vertical windows in the south- east and south-west facades and roof windows let in more than three times as much light as in a traditional house.
A weather station on the roof, together with temperature and CO2 sensors in every room, ensures a good indoor climate – protecting against superheating, ven- tilating with fresh air, and switching the lights on and off according to needs and weather conditions – and saves energy.
An average daylight factor of 7% in liv- ing rooms and up to 4% in the innermost part of the rooms – even with a window area of only 28% of the floor area.
All rooms get daylight from at least two sides.
Vertical windows with iron-free glass ensure that up to 85% of the light is transmitted through the windows.
Plenty of fresh air is ensured by a combination of automatically controlled natural and mechanical ventilation with heat recovery (hybrid ventilation).
Strategically-placed windows ensure optimal use of daylight and adequate air flow.
The special design and volume of the rooms, together with the use of sound absorbers, ensure a good acoustic climate.
Use of healthy materials ensures mini- mal impact on the indoor climate.
独特的设计使”太阳堡”充分使用可再生能源并实现太阳能自给能源，除了满足自身消耗，还有盈余能源。阳光透过屋顶和立窗源源不断地提供能源。冬天，阳光透过窗户为房屋贡献了所需的一半能源，太阳能和地热能综合系统贡献了房屋室内采暖和热水供应所需的另外一半能源。在朝南的屋顶上，50 m2太阳能集热板可直接收集太阳能，用于室内采暖和热水供应，250 m2太阳能电池可将太阳能转换为电能。由于其独特的设计，每年产生的能源比消耗的能源多出9千瓦时/平方米。
太阳堡幼儿园的能源由50 m2太阳能集热板，1000 m地热管道和250 m2太阳能电池提供（每天产生34 kW电能）。 满足房屋及其控制系统和家电工作的能源需求。
Solhuset uses renewable energy sources and was designed to produce more en- ergy than it consumes.
The design, orientation, construction materials, windows and the intelligent control of the indoor climate ensure an energy consumption rated as energy class 1, equivalent to the requirements of the Danish Building Regulations 2015 – even without including the energy produced by the renewable energy technologies in the house.
The sun supplies Solhuset with heat through the roof and facade windows. The windows contribute half the heat needed in wintertime. The remaining requirement for space heating and hot water is produced by a combined solar and geothermal system. Strategically placed on the south-facing roof, 50 m2 solar collectors harvest energy directly from the sun and convert it into heat and hot water, while 250 m2 solar cells con- vert solar energy into electricity. Solhuset was designed to produce 9 kilowatt-hours per m2/year more than it is expected to consume.
The surplus energy production means that in about 40 years the centre will have paid back the CO2 emitted during produc- tion of its primary building materials. That makes Solhuset CO2 neutral throughout its lifetime.
Solhuset is designed to:
be CO2 neutral and self-sufficient in energy,
meet the requirements of Danish energy class 1 (51 kWh/m2/year) even before the use of renewable energy,
produce 9 kWh/m2/year of surplus energy. Energy for Solhuset is produced by the 50 m2 solar collectors, 1000 m geother- mal pipes, and 250 m2 solar cells (34 kW).
This meets the operational needs of the building, the control systems and the appliances.
