HOME OPTIMISING THE USE OF SOLAR ENERGY
A 40 strong team of students from The University of Nottingham are representing Britain in the first ever Solar Decathlon Europe – an international house building competition featuring the very latest in sustainable solar architecturewhich takes place in Madrid between June 18 and 27, 2010. The Nottingham H.O.U.S.E (a family home optimising the use of solar energy) is competing against 19 other universities from across the world to design, build and test drive Europe’s most energy efficient home. Academics, researchers and students from the various disciplines in the Department of the Built Environment have partnered with a select group of industrial sponsors and specialist consultants to make the project possible. This full-scale home is designed to the world’s most stringent design codes German Passivhaus Institute Design, UK Code for Sustainable Homes Level 6 (Zero-carbon), Lifetime Homes compliant & secured by design compliant. This is the first time all these codes have been have been complied within a house of this type - this in itself is a massive challenge regardless of the fact we are using students to design and build it. It will be a fully functioning home which is UK building regulations compliant.

The house has attracted major sponsorship from Saint Gobain - a world leader in the design, production and distribution of construction materials, plus a number of important players in the Built environment industry which are aiming to lead the way in the future of sustainable architecture.
The Nottingham H.O.U.S.E has many novel features to reduce energy such as a new low energy cooling system developed by the University and partners. The home’s modular volumetric design allows it to be transported and assembled rapidly. The house is travelling from Nottingham to London to be assembled for the first time at Ecobuild, the world’s largest event for sustainable design, construction and the built environment, and from the beginning of June it will be taken to Madrid where the students have just one week to assemble it and landscape the garden before putting its low energy technologies to the test.
Organised and supported by the Ministry of Housing of the Spanish Government together with the US Department of Energy The Solar Decathlon Europe 2010 is judged on 10 separate areas of expertise. • The architectural merit of their home • Industrialisation and market viability • Engineering and construction • Solar systems • Electrical energy balance • Comfort conditions • Communication and social awareness • Household functionality • Innovation • Sustainability
The competition aims to educate the general public on renewable energy, energy efficiency and the technologies available to help them reduce their energy consumption; to encourage the use of solar technologies; and to demonstrate that solar houses can be built without sacrificing energy efficiency or comfort, and that they can be both attractive and affordable.

+01 ARCHITECTURE
The Nottingham HOUSE has been designed for a small â&#x20AC;&#x153;starterâ&#x20AC;? family. In addition, it provides interesting and useful spaces to encourage and support family life. Furthermore, it offers comfortable interior spaces regardless of the season, nor the time of year, by employing environmental strategies that minimize energy consumption. Sustainability as a concept has been explored through the idea of treating the H.O.U.S.E as a module and using its repetition to form a continuous urban fabric. In doing so, this creates an extensive urban landscape.

A prefabricated modular construction scheme was employed to enable an efficient and controlled construction process, as well as to facilitate its transport to the site using lorries. Materials were chosen with regards to minimizing total energy consumptions and maintaining an inexpensive structural scheme. This also allows the student team to build the majority of the house, as well as providing alternative teaching methods.

+03 SOLAR SYSTEMS Two types of solar energy systems have been developed in order to meet the house’s full energy demands • Solar Electric Energy Demand • Solar Thermal Energy Demand
daily Water budget
• Shower 50 Lt
Using a water budget that is specific to two people living in a house, it has been calculated that each person will require 50 litres of water at 60oC per day (which will be mixed with cold water afterwards). To obtain this, 9.45KWh/day will be required. This requirement will be met using solar thermal energy technology. In this case, a 5m2 horizontal solar collector has been integrated into the roof.
• Dish washer 15 Lt • Washing machine 50 Lt
• Water for dinner party 15 Lt • Cooking 2.3 Lt
• Passive downdraught evaporative cooling 80 Lt

Solar Thermal Technology Solar collector: 5m2 • Hot water for 2 people = 50 Lt / 60oC daily
• Lighting • Electrical appliances • Heating & Cooling
The energy balance analysis illustrated in the graph shows a surplus of electrical energy generated by the PV array when compared to the electrical energy demands of the house. This surplus will be exported to the grid, allowing energy demands to be offset when they are not met by the PV array. As a result, the house achieves full energy self-sufficiency.

• Temperature • Humidity • Acoustic • Lighting • Air quality
Passive environmental design strategies have been incorporated into the design to provide a comfortable environment. The building envelope is heavily insulated and the use of glazing is controlled to offer good daylight, to reduce summer gains and to maximize winter gains. The PV array system on the roof prevents excess solar gains, and provides electricity to run the mechanical ventilation and heat recovery system. These systems are used for ventilation, heating, and cooling when passive methods are inappropriate. In addition, a Passive Evaporative Cooling System has been developed in the double height space. These cooling strategy challenges will take their full effect in the Madrid summer.

One of the tasks consists in inviting fellow competitors to dinner to demonstrate the effectiveness and energy efficiency of the house, but also to share something special, so we invited SAT BAINS, a Nottingham based Michelin star chef and IAN DEXTER a Chelsea show award winner landscape designer to help us conceive a menu that can be sourced from the houseâ&#x20AC;&#x2122;s own garden blending british traditional ingredients with a spanish twist, all very inspiring!!!!

+08 INDUSTRIALIZATION & MARKET VIABILITY Our approach is orientated towards starter families, which happens to be a major requirement into the UK today. The design is a two-storey solution, which acts as part of a housing system that could potentially generate extensive urban landscapes. More specifically, each module could either form half of a semi-detached house or be part of a terrace, as well as continuing to provide each family with a private outdoor space. The environmental strategies developed allow the house to be used in a widerange of geographical contexts, either within the UK or throughout Europe. As a result, the chosen construction system is highly industrialized and employs a modular system which can be prefabricated, packaged and transported to a variety of sites. Nevertheless, it continues to sustain an efficient and controlled construction process.

The house is designed as a system that can be used in many different climatic contexts, therefore enhancing its market viability. Its systems can be adapted so that the house can perform efficiently in the southern conditions of Europe (Madrid), where the double height space is used for passive cooling through the evaporative system, as well as in the North of Europe (Nottingham), where the same space is used for passive ventilation through the stack effect. An integral part of the Nottingham House design was the decision to create a two-story building that is “L” shaped on plan in order to provide a courtyard garden. This external space provides shading in summer and a focus for the public areas of the house. Furthermore, it allows the family to grow some of its own food, which often forms a large part of the family’s energy footprint. Environmental design stategies Summer Day

+09 INNOVATION & +10 SUSTAINABILITY >12
These two aspects of the contest represent the strategic components of the proposal compared to the preceding 8 aspects and therefore are evaluated together.
Grouping possibilities The possibility of being able to form groups of the house enables the creation of sustainable communities and would therefore boost the use of systems and strategies.
