Case study (Arco Cego, Lisbon)

Arco Cego (Case Study) History of the surroundings  The Bairro Social do Arco do Cego is one of the first planned residential areas of Lisbon. After the founding of the republic (1910) work began on establishing housing settlements in what were then still the suburbs of the city. These were supposed to develop standardized living areas within the framework of a social house building program. A decree of April 5, 1918 sought a remedy to the housing difficulties of the poor and the gradual solution of the problems acknowledged in the old quarters by building new living areas for the working classes.  Under the leadership of the architects Edmundo Tavares and Frederico Machado small semi detached houses fronted by little gardens began to be built in the Arco do Cego quarter in Political change caused considerable building delays during the following years so that the new settlement was not officially opened until 1935 under the Salazar regime. In the meantime the general shortage of accommodation had increased, and in addition the political line clearly changed. The result was that - allegedly because of mistakes made in planning the project - rents were set so high that people on low incomes could not afford them. Instead of the people they were intended for, tenants from the lower levels of the bourgeoisie such as civil servants and members of the national unions were preferred. Today the quarter lies on the edge of newer tower block complexes; in contrast to these it appears an almost idyllically peaceful area.

Lisbon municipality Master Plan main policies for the area Lisbon municipality Master Plan has a long history of master plans. Recently a new master plan was adopted. The case-study area is divided between two main urban planning units – UOPG-3 and UOPG 4. Regulations of the plan establish that: Recreational and Production spaces The green open and recreational spaces must be consolidated as unbuilt, permeable and planted spaces, generally on soil organic natural terrain, which may have (....) recreational and production, including urban gardens and nurseries, and can integrate collective equipment and infrastructure to support recreational and leisure facilities including food and beverage, and tourism, without under observation of other rules stated in the regulations

Lisbon municipality Master Plan main policies for the area Spaces for Special Equipment Use Consolidated spaces for special-use equipment are public collective equipment, public services and facilities of security services, existing or proposed, for which the continuation of these uses is proposed, as well as complementary uses, provided they do not occupy an area greater than 20% and a building rate of 1.5. Consolidated spaces for special-use equipment can also integrate individual buildings or small urban fronts with other existing uses. Any intervention in these areas must observe the urban and landscape context, particularly with regard to the height of the facade and volumetric proposals. The rate of permeability is at least 0.3 and may exceptionally be lower by virtue of particular interest to develop public programs. Consolidated spaces for special-use equipment comprise a subcategory of spaces using special equipment associated with green area, marked in Plant qualification of urban space

Lisbon municipality Master Plan main policies for the area Spaces for Special Equipment Use associated with green areas Consolidated spaces for special-use equipment comprise a subcategory of spaces using special equipment associated with green area, marked in Plant qualification of urban space In areas of special equipment use associated with green area is not allowed any building or expansion of existing buildings beyond the sealed areas by the entry into force of the PDML, unless exceptional circumstances, provided they do not exceed 10% of the area already waterproofed and heritage is safeguarded existing vegetation and landscape. Any intervention in these areas must observe the urban and landscape context, particularly with regard to the height of the facade and volumetric proposals. The use as equipment is maintained until the end of life of the existing facilities or its justified need to other collective equipment. After disabling the current use of equipment, these spaces are to be maintained as green areas where it is admitted to install playground equipment, sport or culture but only in the sealed areas by the date of entry into force of the PDML.

Lisbon municipality Master Plan, July 2012 main policies for the Avenidas Novas area - Enhance the housing function in the Avenidas Novas area in more internalized urban networks, protecting from crossing traffic; - Reduce the weight of private transport and promote increased pedestrian area, with consequent improvement in the quality of urban life; - Regenerate the central axis of the city, increasing pedestrian public space, promoting trade and equipment in the margins by their articulation with the same space; - Upgrade the biophysical requalification of water lines and respective margins, to ensure their role in terms of functional and landscape, and ensure proper integration in areas of urban green spaces and allowing public enjoyment of these spaces ; - Decrease the rate of flow of rainwater, minimizing the influx of large flows at critical points at small intervals times and decreasing water entering the piped drainage system, thereby reducing the risk of flooding, implementing retention basins and infiltration.

Exercise main lines

Exercise  The challenge is to apply the concepts taught during the lectures to the specific area of study, considering the neighbourhood Arco Cego to ensure it will have very good performance in environmental, social and economic to the next generation (25 years)  Main aspects to be consider in the different lectures:  Vision, strategy, problems and challenges  Plan, project, impact and sustainability assessment  Green economy and sustainable consumption. Challenges and sustainability in cities  Sustainable construction factorial chalenges – Environmental Life Cycle Assessment – Water and materials  Environmental management program  Near zero energy and carbon

Exercise Approach: A. What are major challenges and what solutions can be found B. Make contributions to the municipal plan in relation to: - mobility - working and local trade areas - water reuse and recycling materials - Improve energy building efficiency and the use renewable energy to achieve near energy and low carbon At a minimum point B should be done. Contributions to point A will reflect a higher capacity and will be analyzed in your responses to the test and exam

Exercise Questions as related to lectures: 1. Explore what do we want from this area Consider: - the policy orientations and regulations of the PDML, that will act as restrictions, or encouragement, to change - identify the main problems of this area - find out what users, people on the street, expect of this area, what they would like to see happening (their vision and objectives for the area) 2. Gap analysis - What needs to be done to improve the environmental context and sustainability of the area - check what the municipal master plan says, as provided - consider what the users interviews indicated as public wishes for the area - assess potential improvements to be developed that meet planning requirements and the desires of the users Lecture 1 and 2

Exercise How would green economics approach apply? 3. Identify from lectures what would be priorities to implement green economics: - topics more relevant - Four relevant priority suggestions to enhance the sustainability of the area Sustainable construction – what factorial challenges could be define as target? 4. Identify actual level and potential challenge -What is the actual situation (using LiderA Checklist) ? -Potential measures in specific points (acupuncture)? Lecture 5 Lecture 2 and 8

Exercise Environmental Management Program 5. Identify potential solutions to close the cycles water and materials -Key points in life cycle water and materials and strategies? -measures to close water cycle and eco-materials ? Near zero energy and carbon 5. Identify potential solutions improve energy performance and use renewables -Estimate the energy consumption indicators and local production, how near zero energy and carbon? -Measures to improve energy performance, carbon level and refurbishment actions ? Lecture 5 and 4 Lecture 6
