The ReVolt House is a floating and rotating dwelling designed by a multidisciplinary team of students from TU Delft for the Solar Decathlon 2012 competition. It aims to provide a dwelling that uses less energy without sacrificing comfort by integrating solar energy technology with appealing design in and being an example of sustainable development. In pushing the boundaries of building innovation the project raises awareness for cutting-edge building techniques that can improve the current strategies followed withing the building practice in the Netherlands and abroad. The determining parameters for the design are lightness, prefabrication, thermal performance, appearance, assembly and costs.
Floating is representative of the Dutch context where water is abundantly present (partly as landscape, partly as a threat) and entire neighbourhoods are planned on water. The design of the house shows how to build in a sustainable way where the water/landscape gets tightly interwoven with the architecture and energy concept.
Rotating The house will rotate for climatic and energy aspects. One side of the house will have a closed facade, which will continuously face the sun summer, shading the interior and minimizing the solar heat gain. This “heat shield” will integrate a passive solar cooling system. Conversely, in winter, when the suns’ altitude is lower, the “open” glass facades will continuously face the sun. This generates a solar heat gain for the interior (passive heating), which requires less energy for an actual heating system. Since the house is floating frictionless on the water the rotation won’t require much of an effort.
Reducing energy demand is achieved by:
1. Improving the building and appliance’s properties
2. Lowering energy demand by altering user behaviour
While the first method has almost reached a threshold concerning optimal performance, the latter strategy has huge potential as human comfort is a state of mind, which can therefore be altered with appropriate stimuli.
The ReVolt House introduces a new type of user interface for the home automation system, which would be user-dependent. The system is able to learn user habits and comfort and consequently optimise them over time. The comfort analysis allows the user to indicate discomfort on a relative comfort scale, rather than on a Celsius range. For example, the system would be able to detect if the users are watching TV and dim the lights accordingly, running on a treadmill and reduce the needed amount of heating, or walk around in shorts during winter, in which the system would recommend wearing something more appropriate to reduce the heat demand.
The team was set-up by the Building Technology department of the Architecture Faculty, the Delft Energy Initiative and Energy Club and consists of international students from architecture, sustainable energy technology, civil engineering, policy and management.
The original Solar Decathlon is a competition organized by the U.S. Department of Energy in 2002. Since then 20 Universities from across the globe meet every two years to design and build an energetically self-sufficient house at the National Mall in Washington DC. The houses solely run on solar energy and incorporate technologies that maximize its energy efficiency. In 2010 for the first time, a similar event was held in Europe. Solar Decathlon Europe aims to:
