Improving Environmental Standards in an Urban Area.

 

Urban design has seen an increase in the need for developments to give more consideration to the environment as opposed to social and economic factors being at the forefront of design (Carmona, 2009). The social, economic and environmental dimensions make up the three pillars of sustainability (Ekins, 2000). Although the aim is equality between the pillars, it is believed that ecological and environmental constraints are ‘the most fundamental measure that should be considered on sustainability’ (Modifi, Shemirani and Hodjati, 2013, pg. 290). There needs to be more emphasis on the environment, and how this is incorporated into urban design.

 

Firstly, it is important to introduce the features that make a development obtain a high environmental standard. Utilising the work by Carmona (2009) it is apparent that a ‘settlement is like a living organism’ (Carmona, 2009, pg. 53), it uses food, fuel and water, whilst releasing waste, solids and other pollution (Carmona, 2009). Therefore it is important to reduce the consumption of resources whilst also limiting the waste that is produced.

 

Resource efficiency, energy and C02 emissions can be addressed by the use of renewable energy, with various technologies available for implementation. The development of the Western Harbour in Malmo, Sweden provides a good example. Malmo introduces renewable energy sources into an urban neighbourhood. Many people believed that renewable energy, such as ‘large solar production projects, or wind energy farms, require relatively remote sites’ (Beatley, 2007, pg. 38). Whereas Malmo shows that these methods can be incorporated into urban areas.

A lot of the time people only seem to address creating green energy, however using an example from Vauban Passivehaus in Freiburg, Germany, organic household waste is allowed to ferment anaerobically with the gas being produced used for cooking gas and the excess water being treated and returned to the water cycle (Vauban, 2013). Utilising a method like this shows that some of the waste is being used energy creation, reducing the amount going to landfill.

 

Finally, addressing water. Sustainable urban drainage systems are being used more and more in design. They can be used for reducing the potential of flooding, but they also have advantages with regards to biodiversity and water treatment. In Ruwenbos, Netherlands, they have adopted a swale like drainage called wadis, with the two-tiered system filtering out pollutants before intercepting the water (DAC, 2014). Using this method in a design can improve the site aesthetically and ecologically whilst reducing the surface run off and filtering it at the same time.

 

The above provide a brief overview of three aspects that could be incorporated into a design in order to improve the environmental standard of that development. By no means are they strict and rigid design possibilities, they just give an example to the types of techniques that are being used in various places. Therefore, if a developer aims to improve the environmental standard, there are ways and means and successful precedents of this. In my opinion methods like this should be used on any development, I feel developers sometimes stray away from this idea for cost, however in the long run it is beneficial for the environment. If only some of the methods were implemented it would have a much greater effect than having non of them at all.

One thought on “Improving Environmental Standards in an Urban Area

  1. Hi, Matt!
    I think your opinions make it sense. According the official document of ROYAL COMMISSION ON ENVIRONMENTAL POLLUTION(available here: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/228911/7009.pdf), Most of the cities are facing a set of visible challenges such as climate change, the wasteful use of natural resources and so on. Your comment regarding the renewable energy benefits brought was of key interest to me.
    I support the your opinion that it is the high time for human to use some more efficient, eco-friendly and renewable engineering techniques to change the approaches producing and using energy. “The life time of oil and gas resources is usually only a few decades; whereas life time for coal is a few centuries” (Twiddle and Weir 2006).As stated by the Proposal for a Directive of the European Parliament and of the Council on the promotion of the usage of energy from renewable sources, they draft a legally compulsory target of 20% renewable partition in the overall final energy consumption in Europe by 2020.
    In many communities more solar panels are installed on a south-facing roof to help the environment by using the electricity you generate and make the house work more efficiently. Energy itself is fundamental to the development of society, someone can use the energy more efficient or eco-friendly which not only means can maximize the competitiveness but also reduce the environmental challenges such as climate change.
