The Nottingham H.O.U.S.E

HOME OPTIMISING THE USE OF SOLAR ENERGY

The Nottingham H.O.U.S.E (a family Home Optimising the Use of Solar Energy) is the result of academics, researchers and students from the various disciplines in the Department of Architecture and Built Environment collaborating with a select group of industrial sponsors and specialist consultants.

This full-scale home is designed to the world’s most stringent design codes – The German Passivhaus Institute, 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 combined within a house of this type - this in itself was a massive challenge despite the fact that students designed and built this as part of their teaching and learning experience at Nottingham. It is a fully functioning home, compliant with all UK building regulations.

The house 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.

A 45-strong team of students from The University of Nottingham represented Britain in the first ever Solar Decathlon Europe, which took place in Madrid, Spain in June 2010, to compete against 18 universities from across the World in designing, building and test-driving Europe’s most energy efficient home.

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.

In March 2010, the H.O.U.S.E was shipped from Nottingham to London and assembled for the first time at Ecobuild 2010, the world’s largest event for sustainable design, construction and the built environment. At the beginning of June 2010 it travelled again to the Villa Solar in Madrid, where the student team assembled it and landscaped the garden in just a week.

Now the H.O.U.S.E has become part of the Creative Energy Homes Project at the University of Nottingham’s main campus for its long-term monitoring and dissemination of its technologies.

The H.O.U.S.E’s low energy technologies were put to the test in the Solar Decathlon competition’s 10 separate areas of expertise: •The architectural merit of the home •Industrialisation and market viability •Engineering and construction •Solar systems •Electrical energy balance •Comfort conditions •Communication and social awareness •Household functionality •Innovation •Sustainability This booklet details how the design of the H.O.U.S.E responded to each of the above criteria, as well as telling a little of the story of the project. When visiting the Nottingham H.O.U.S.E please look out for the all the sustainability features outlined here.

Groups of 5th year and Masters

students of architecture were asked to produce designs for a Zero Carbon house which could compete in the Solar Decathlon Europe competition, but would also form part of a sustainable master plan in a deprived

area of Nottingham.

Once the winning proposal had been selected, all of the students came together to refine the design, aided by consultation with industry partners for technical advice on products that

Use of Solar Energy would meet the ethos of sustainability, economy and innovation. Once the design had been progressed to a suitable stage, a unit of thirty secondyear architecture students and fifteen third-year MEng students was enlisted

to help build the H.O.U.S.E, and it is this prototype that stands before you today.

Please keep in mind that much of the information here about the H.O.U.S.E is related to its design performance

when located in Madrid. Long term monitoring of the H.O.U.S.E located in Nottingham will provide us with actual performance data for its location in a cooler climate with less solar energy resources.

+01 ARCHITECTURE

The Nottingham H.O.U.S.E 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

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 south facing inclined solar collector has been integrated into the roof.

• Shower 50 Lt • 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.

+05 COMFORT CONDITIONS

• 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 for the H.O.U.S.E including 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.

A key element for disseminating the project has been our presence on Facebook, Twitter, and other social networking sites; but also extremely important was our presence at Ecobuild 2010 and our various VIP day events, chiefly the Sat Bains Cookery Master class. Both these events are detailed in this brochure. When the H.O.U.S.E was back in Nottingham, visits were facilitated through the Ten Act10n project.

+08 INDUSTRIALIZATION & MARKET VIABILITY Our approach was 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 semidetached 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 H.O.U.S.E was 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 H.O.U.S.E 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.

These two aspects of the contest represented 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.

The H.O.U.S.E was awarded a â&#x20AC;&#x153;Sustainabilityâ&#x20AC;? prize at the competition in Madrid.

+MEAL WITH SAT BAINS

winning landscape designer, to help us conceive a menu that uses traditional British ingredients (sourced from the houseâ&#x20AC;&#x2122;s own garden) but blends them with a Spanish twist.

One of the tasks we undertook during the Solar Decathlon competition involved inviting fellow competitors to dinner to demonstrate the effectiveness and energy efficiency of the house - but also to share something special.

We teamed up with Sat Bains, a Nottingham-based Michelin Star chef, and Ian Dexter, an award-

The Sat Bains Cookery Masterclass VIP event took place in May 2010, in Studio 7 of the Kings Meadow Campus at the University of Nottingham - the very studios weâ&#x20AC;&#x2122;d been building the H.O.U.S.E in!

Tom Corbett and Emily Costain, both members of the H.O.U.S.E Communications team, cooked alongside the Michelin star chef in front of a live studio audience. The event was an opportunity for the Nottingham H.O.U.S.E. team to thank the industrial sponsors of this

project, without whom we would not have been able to compete.

The Comms team reproduced this same meal - without Sat!, during the competition in Madrid.

+AROUND THE WORLD...

ECOBUILD There have been many unifying and uplifting moments throughout this project, but the king of all these rushes was seeing the H.O.U.S.E., the planters, the posters and all standing vibrant and proud on the first morning of Ecobuild 2010.

Held in Earlâ&#x20AC;&#x2122;s Court Olympia, London, Ecobuild is biggest event in the world for sustainable design and construction.

Over 1,500 organisations exhibit each year, representing the entire spectrum of sustainable construction products

for new build, refurbishment, residential and commercial projects.

SHANGHAI EXPO 2010

We were kindly invited to exhibit at the 2010 event, which also offered us a chance to practice both the transport and assembly of the modules, and the presentation of the project.

We had many key visitors from the entire sphere of the built environment, including the then Minister for Housing.

The H.O.U.S.E was awarded the first prize for best use of timber at Ecobuild.

The Nottingham H.O.U.S.E. (scale model, posters & videos) was exhibited as part of the Zero-Carbon, Zero Waste exhibit in the Zero Carbon, Zero Waste Pavilion and is a part of the Nottingham University and United Kingdom presence at the Shanghai Expo 2010.
