TIA Sustainable Building Competition Theme The competition will propose a choice of two themes: Redesign and retrofitting of an existing office building A new commercial complex to be built in a city 1. The redesign and upgrading of an existing office building should propose ways in which significantly improvements can be made to the internal comfort conditions, thermal performance and the sustainability of the building concerned. The building should have a maximum of three floors and should clearly demonstrate how the new design has improved the energy-efficiency of the heating, cooling, day-lighting and comfort of spaces as well as the quality of life in them. Attention should be paid to the choice of site, its climate, urban context and local and regional as well as global issues of sustainability. Competitors are required to set their own detailed brief. As an indication, the gross floor area of the building should be not less than 300 m2. 2. The commercial complex, should be a new building for the 21st century, located in an urban setting exhibiting relevant architectural and environmental information. The building should be designed to include office facilities not less than 300m2 and may also include other commercial or residential accommodation. The building should demonstrate what the students think offices will be like in the 21st century, and could be designed for well into the future up to 2020 or beyond. An indication should be made as to how the office will fit into the fabric of an existing city and its infr-structures. Participants in the competition may work to a detailed brief established within their Schools or develop their own briefs. Each scheme should be accompanied by an introductory description of the project location and existing environment, site layouts, relevant climatic information, and a general briefing. The Competition Project may provide the opportunity for in-house seminars, lectures or workshops on the issues being developed in the project by individual Schools of Architecture. Methods of illustrating effectively the quantitative or qualitative merits of each scheme can be developed with the help of project tutors. Principles 1. Life Cycle Management. This requires that raw materials be kept within a single cycle as much as possible. This means minimising construction and demolition waste, lengthening the life span of building components, increasing the flexibility of use of dwellings, and promoting the recycling of materials and products after the demolition of the building. Such practices slow the rate of depletion of finite raw materials and limit the negative environmental impacts resulting from any material over its total life cycle. The constituent elements of all raw materials used in construction are released again in one form or another during demolition and it is more environmentally advantageous to achieve a high-grade reuse of these waste materials. The choice of sustainable building materials should take into account: - prevention of the unnecessary use of, and the promotion of the efficient use of, materials - use of renewable and recycled sources of materials - selection of materials with the least environmental impact Step 1. Prevention of the unnecessary use of, and the promotion of the efficient use of, materials While in some industries, such as the packaging industry, the quantity of material used is an economic, political and environmental issue. In the building sector such material efficiency is not yet an integral part of discussions on the environmental impact of buildings. Every client, investor or government body should initially carefully evaluate the need for a new building at all. If a building is indeed required then it is at the early design phase in particular that significant improvements can be achieved in the material flows through buildings, for instance, by investigating the possibilities for renovation and reuse of existing buildings rather than creating a complete new building at all. Secondly, designers can design a building to be as materially efficient as possible, by minimising the resources needed. This can be done by: Optimising the floor plan and construction detailing Rationalising the sizes of components to avoid demolition waste during construction Matching the expected lifetime of a component to the expected life time of the building. Step 2. Use of renewable and recycled sources By making use of renewable and recycled sources the life cycle of building materials can be closed. Renewable sources will be reproduced by nature during the lifetime of the material. Thus recycled materials can enter a second building life, thus saving other natural resources. Clients and designers can plan for future recycling by: Not using composite materials that cannot be separated at the end of the life cycle Not glueing and sealing components together Designing buildings for dismantling and reuse, not for demolition. Step 3. Selection of materials with the least environmental impact The environmental impacts of materials result from use over a complete lifetime. Typical environmental issues are: raw materials, embodied energy, emissions, hindrance, waste, recycling, repair and durability. It is important to select those building products which have the lowest environmental impact. 2. More efficient use of energy In promoting the efficient use of energy one is aiming far a reduction in the consumption of finite energy sources, such as coal, oil and natural gas. This breaks down into the need to undertake the following steps: reduce the demand for energy, increase the use of renewable energy, increase energy efficiency. There are many ways the above can be achieved including the judicious use of site planning, building form, levels of insulation, thermal mass, efficiency of equipment, summer shading, the use of buffer spaces, renewable energy and good windows. The Standards of energy efficiency expected may be related to the following figures for heating, lighting, water heating and equipment : - 150 kWhr/m2/annum - typical current Best Practice modern building energy use - 50 kWhr/m2/annum - low energy building, a 2010 Standard for European buildings. - 25 kWhr/m2/annum - super-low energy buildings, achievable with the use of renewable energy. 3. Promotion of quality Life cycle control and a more efficient use of energy are both forms of quality promotion. The Competition entries should demonstrate that they have considered the quality of life of the building occupants, and the citizens around the building, from the point of view of: - health (exclusion of toxic materials and gasses), - sound or noise (both internal and external) - comfort (ventilation, shading, passive solar heating in winter only) - control (who controls and how is the indoor environment controlled) 4. Sustainable new construction Sustainable building issues range from the environmentally sound integration of dwellings into the surrounding residential area to the drawing up of a specification in such a way that the future, high-grade re-use all building components is possible. The main thing is to keep both the short and long-term impacts on the environment to a minimum. 5. Sustainable refurbishment The prime motivation in sustainable refurbishment lies in the need to contain the negative environmental impact of refurbishing. The refurbishing process in particular offers an additional opportunity to combat existing environmental problems, usually with regard to the indoor air quality and movement, noise, humidity, condensation, toxins and ambience. These include: - noise pollution caused by traffic and neighbors - emissions al hazardous substances in the ground under suspended floors - emissions of hazardous substances from existing construction materials (eg.asbestos) - high energy consumption for heating and cooling - poor ventilation which impairs the quality al the indoor environment - cold bridges in the construction, which lead to the formation of mould and damage to the building. Competition objectives One of the most effective ways of expanding knowledge on Sustainable architecture and its influence on architectural design is to make it part of the core curriculum in Schools of architecture. A competition amongst Schools of Architecture in the countries of the European Union seems an appropriate way to encourage these institutions to do be more active in this important and rapidly developing field. The aim of the competition will be to produce a design for a refurbishment of an office block or a new commercial complex for the 2000. In the process of designing these buildings students will also address the issues of what energy-efficient buildings of high architectural quality might look in the future, be they refurbishments or new-build. New technologies have often been the inspiration for new forms of architectural expression in the past. In this Competition students may use as wide a palette of design strategies and elements as they like from the past, the present or the future, as long as they combine in the design to promote the 'Sustainability' of the eventual solution. The competition is open to all students of architecture who at the time of application are enrolled at universities, polytechnics, and colleges in the following countries: Austria, Belgium, Denmark, Germany, Finland, France, Greece, Great Britain, Ireland, Italy Luxembourg, The Netherlands, Portugal, Spain and Sweden. Each participant may submit only one application. Teams may participate only if all team members are individually eligible and will be regarded as one participant. Team members may not submit individual applications as well as a team submission. Official language and deadlines All submissions to this European competition for students of architecture must be in English only, including the labeling of drawings and the text of Project Reports.

The value of each of the regional awards will be 2000 Euros and the honorable mention 500 Euros. The total prize money available is 24000 Euros. Copyright Documents submitted with projects for which prizes have been awarded become the property of the awarding body. Copyright remains with the author. The award of this promotional prize has no bearing on whether or not a project will actually be implemented. However, should an interest be expressed in implementation of a project and drawings accepted for this purpose, a fee will subsequently be paid for such drawings. Any further work will be remunerated accordingly. Moreover, the awarding body has the right to publish any submitted works without payment of a fee but with mention of the name or names of the submitting persons. For this reason, we recommend applicants do not submit originals or unique items. Awarding prizes and Competition exhibition Following the announcement of the jury'sprize decisions, there will be an official ceremony for the awarding prizes as well as an exhibition of prize-winning projects at Oxford on the 12th July at the TIA 3rd International Conference. The exhibition of the drawings will be shown at the TIA 2000 Conference in Oxford and then subsequently exhibited in a number of locations in Europe. Catalogue Prize-winning projects will be published in a competition catalogue to be launched at the TIA 2000 Competition project Participants will be expected to perform the following tasks: - Layout, including buildings of the area with a scale of 1:500 - Building plans, sections, and elevations with a scale of 1:100 Three-dimensional representations and photographs of the models (not the model). - Facade details, cross section, and details of energy-relevant facilities with a scale of 1:50-1:20 Project Report outlining: Climatic data of the city in which the building is to be built: annual sunshine, mean maximum and minimum temperatures, The strategies of Sustainability developed in the project Environmental Performance of the building internally including shading studies, air flow witChin the building and ventilation strategies, use of sustainable building materials and energy performance figures or the project over the course of a year Participants may submit one DIN A0 sheets (1188 x 841 mm, portrait format).
