Espora and acoustical / thermal environment

Green roofs not only contribute to the insulation of facilities -indoors to outdoors or outdoors to indoors- but also can absorb urban noise pollution.

In this sense, they contribute to urban well being by reducing both outdoor noise -traffic or aircraft noise- and the noise produced by indoor activities.

We can highlight several peculiarities of the Espora module and they are available in the follow link.

 

 

Green roofs not only contribute to the insulation of different buildings, but also can modify room temperature significantly in cities.

In this sense, they mitigate the urban heat island effect, during the daytime and at night, improving the well-being of its citizens.

Thermal behavior of the Espora module varies depending on:
• the amount and type of substrate
• the substrate’s humidity
• the type and state of vegetation
• the air chamber ventilation
• contextual hygrothermal conditions

For more detailed information on the thermal environment of the Espora module, we have the following link.

5 solutions to increase green space in today's cities

The cities of today face the challenge of converting urban land into green space to comply with WHO regulations which determine that between 10 and 15 square meters per inhabitant are necessary.
The scarcity of free urban land that is available to create new green spaces is the main problem in cities. This forces us to find new alternatives and solutions that contribute to increase the urban green infrastructure, creating a new natural layer of biodiversity that is essential for the improvement of the well-being of its inhabitants.

5 reasons for creating urban green spaces

Why is it good for today's cities to work towards spreading green spaces?

Many cities are starting to work towards spreading green urban spaces because they provide great benefits for urban areas and their inhabitants, as we explained in "The 8 benefits of spreading green spaces in cities".

In today's post, we want to reflect on why ESPORA has led us support the creation of a new product that contributes to the growth and development of green spaces in urban areas.

Improve environmental conditions in cities

Some of the problems faced by cities today are air pollution, urban heat and extreme temperatures in summer and winter.

The creation of an urban biodiversity layer is the solution to these problems, as they significantly contribute to the improvement of environmental conditions in cities in many ways:

  • Green roofs act as sinks for CO2, the gas responsible for climate change. For each 100 square metres of green roof, the gas responsible for the greenhouse effect is reduced by 1.8 tonnes per year. In addition, installing 100 square metres of green roof on top of a building can produce the oxygen needed by 100 people in a year.
  • The pollution emitted by 15 cars in a year can be removed by 100 square metres of green roof, since the leaves of the green roof plants can retain these harmful particles on their surface.
  • Green spaces can reduce the ambient temperature of cities by 1°C, thus reducing the urban heat island and harmful city smog. In this sense, 1°C cooler urban environments prevent the harmful ozone layer that is triggered during intense heat episodes from forming.
  • Another benefit of green roofs is that they retain 40% of rainwater. Also, they can delay water discharge by 18 minutes in episodes of intense rain, preventing the collapse of urban drainage systems.

China is one of the countries with the most harmful smog in cities in the world, as is the case of Shanghai. This problem has forced the city administrations to look for new ways to eliminate mass air pollution and purify the air, such as creating more green areas and developing green architecture.

Greater social cohesion and relations

Who doesn't like to walk through a green park, ride a bike or read a book under the shade of a tree? According to recent studies, cities with more green areas boost social cohesion and relations, since they are meeting points to share and create links between city inhabitants.

Additionally, green spaces positively affect the behaviour of inhabitants. Urban parks build and develop relations between neighbours, strengthening community bonds and sense of identity.

 

Central Park is a 314-hectare green space in the centre of New York, one of the world's most famous and busiest cities. At lunch time in Manhattan, office workers go to the park to develop their relationships with colleagues, take part in group activities or play sports.

They contribute to environmental regulation compliance

In recent years, both the European Union and city administrations have seen the need to ensure the presence of green spaces in cities to improve environmental conditions and the health and well-being of citizens.

Green Infrastructure - Enhancing Europe’s Natural Capital (2013) is one of the European Union's initiatives to promote the design and creation of more natural areas for sustainable development. Since 2013, Member States have been working to implement these guidelines by creating new policies that pursue ecological, economic and social benefits through natural solutions.

In this regard, the Urban Green Index is an indicator that allows the amount of green areas per inhabitants in urban areas to be calculated, as well as the surface area of green areas in a city. According to the World Health Organization, between 10 and 15 square metres of green space per inhabitant are needed to ensure a healthy urban ecosystem.

 

What types of green spaces can a city have? There are multiple ways to incorporate green spaces and create green architecture. For example, vertical gardens on building facades, green roofs, greenhouses, hives and green roads, urban gardens, and many more.

They promote human well-being

Disconnecting from the road and noise of cars for a few minutes can inspire and improve mood. It is about including nature city life, because it increases the well-being and health of citizens. Dedicating part of the day to walking or resting in green areas makes us relax and reflect, which consequently reduces the stress of city life.

According to the World Health Organization, urban green spaces are essential to human well-being, both physically and emotionally. This means that people living in cities with more parks and gardens have a better quality of life than those who live surrounded by high levels of pollution.

More attractive cities

Aesthetics can also change our perception of city life. Decorating a building with plants or grasses not only enriches the existing architecture, but also offers an attractive space for people who spend a lot of time in the building, boosting creativity and encouraging innovation.

In this regard, there are many psychological benefits to greener cities. For example, vertical gardens, green roofs and parks increase a city's attractiveness, since people perceive them to have a better quality of life and healthier and more sustainable spaces.

Direct contact with nature also promotes the use of renewable energies and a greener lifestyle

In addition, recent studies show that more travellers are opting for sustainable destinations, visiting cities that are committed to the environment and nature. One clear case is the city of Reykjavik (Iceland) that stands out for its environmental appeal, with lots of green spaces, high air quality and great biodiversity.

The 8 benefits of spreading green spaces in cities

Green roofs, vertical gardens and green walls are some examples of the green spaces that we can find in the cities of today.

Thanks to ESPORA, spreading green spaces in cities is easier than ever, due to its modularity, ease of installation and low installation and maintenance costs, among many other advantages.

In addition, the spread of a new urban green ecosystem could be the solution to the environmental challenges of today's cities which must evolve towards greener urban systems to improve the quality of lives of their inhabitants.

More and more cities are becoming committed to the innovation of green spaces, since they provide great benefits for both the environment and its inhabitants.

We have compiled the 8 most incredible benefits of installing urban green spaces, which we explain in detail below:

Greater biodiversity

The spreading of green spaces contributes to the creation of a new layer of urban biodiversity. The presence of this new layer with plants that create a habitat and food for species has a direct impact on the generation of wildlife corridors, which are essential for improving the quality of life and well-being in today's cities.

They reduce pollution

One of the most common problems of our cities is the increase in periods of pollution. Plants that are installed on roofs act as filters for some of the most harmful air pollutants.  For example, one square metre of green space can retain up to 200 grams per year of small contaminating particles that are harmful to health.

Improves city water management

Rainwater can be retained in cities and increase humidity. Green roofs can absorb rainwater, reducing runoff that could lead to the collapse of urban sewer systems.

They mitigate the effects of global warming

The increase in temperatures, the rise of episodes of heavy rain and heat waves, and the spread of disease are some of the consequences of dreaded global warming in cities. The creation of a new urban green ecosystem mitigates these consequences, which directly affect the health and welfare of citizens.

Improves the thermal insulation of buildings

The installation of green roofs on the roofs of buildings and private homes provides, among other things, greater insulation that results in cooler temperatures in the summer months and greater warmth in cooler months. Energy consumption can be reduced by up to 25% in summer and up to 10% in winter.

Greater climatic and acoustic comfort

One of the most common situations in urban areas is the Heat Island. This thermal phenomenon creates a temperature increase in areas with lots of building, and it is caused by cars, lights, asphalt and cement. The presence of green spaces in urban planning and buildings help prevent this phenomenon, reducing the city's temperatures by an average of one degree.

In addition, roofs and green walls reduce the reflection of sound in cities by up to 3 decibels and the acoustic insulation of buildings by up to 8 decibels.

As this graph indicates, the greener areas are the ones with the lowest "heat island" effect. Therefore, covering walls with green is a solution to reduce and regulate the heat given off by the city's materials.

And most importantly: it improves our quality of life!

Green presence in our urban environment fosters our connection with nature and consequently can lead us to better human well-being. Numerous studies show the beneficial effects of urban green on people such as reducing stress, decreasing respiratory and cardiovascular diseases, and improving concentration.

Similarly, the use of green spaces in all urban areas is a powerful tool for scientific knowledge and experimentation.

London is one of the busiest and fastest growing cities in the world. For a few years now, London has been turning some of its urban areas back into green spaces to improve the lives of citizens and their connection with nature. National Geographic explains the example of Gasholder Park.

More data for increased optimisation of the urban green ecosystem

Some modular green roof installation systems allow remote data control. Such control and analysis can directly increase the efficiency and optimisation of these spaces. The ESPORA modular system enables installations to be automatically managed and controlled through an app that allows you to control data related to the installation's operation. This information is highly valuable since it shows how the new layer of urban biodiversity is performing and it provides empirical and quantified data about the improved quality of life of the inhabitants.


Maranta ESPORA

Meet the Maranta, the plant of the month for March

Today we'd like to talk about the MARANTA, a plant that comes from the tropical jungles of South America. Due to its origin, it requires high temperatures, humid environments and semi-shade exposure, making it the perfect indoor plant for our latitudes.

It fills the house with life indoors!

As we have said, the Maranta is an ideal indoor plant that forms thick leaves as it grows. Its dense foliage makes it a perfect plant for creating vertical gardens. In addition, it stands out for its colourful leaves, with reddish lines and tones that change depending the light, making it a beautiful plant.

Maranta ESPORA

We used it in our last Epora Vertical Organic Garden installation in a co-working space. The result was spectacular.

In this case, it was combined with Aspidistra, wooden hexagons, and mirrors that created an attractive set of textures and reflections along the staircase.

Humidity, the strong point of the Maranta

Since it is an indoor plant, the Maranta needs to be protected from direct sunlight but it can be kept in a bright area.

It also must be kept away from radiators and stoves which dry out the environment and damage the plant's leaves. It needs daily watering, especially in the hottest months, but in controlled amounts because it can also be damaged by too much humidity.

Maranta ESPORA

A good solution is the Espora organic module auto-watering pot. It ensures a constant humidity at the roots, since they only take the amount of water they need. Vertical garden watering can thus generate large savings in water consumption.

The ambient temperature is another important aspect to consider for its care. The most optimal temperature is between 15 and 25°C, although they can also live between 10 and 30°C. We recommend that you fertilise it with a liquid fertilizer once a month during the growing season that takes place from spring until the end of summer.
