Two percent of the world land mass consists of cities. Cities account for 15% of global gas emissions. Nearly 40% of all raw materials that we obtain in nature are produced for the construction sector and 40% of the energy produced is consumed by buildings. The structures we live in are caused by 30% of CO2release. The largest user of the world’s resources is the artificial environment we create. This means that the built environment is both a problem and a solution for climate change. As such, sustainability has become a phenomenon to be considered for the building sector.
What about Production?
Most of the constructions that make up the zoned environment are not designed to be efficient in terms of energy use. But with the implementation of today’s technology and systems, significant energy savings can be achieved in buildings. We can start by reducing greenhouse gas emissions and energy use of these saving structures. There are also options such as recycling, use of methane gas as a power, regulation of lighting options, increasing the use of solar and other renewable energy sources. An example of this is the Empire State Building in New York City, which reduces energy consumption by 38% per year. One of these arrangements is the renewal of the 6514 window in the building. This renewal process is explained as follows: We use existing frames, we take out the frames, we use and clean the windows. We place a low-emission film between the windows as intermediates. This is called a three-glazed window, but in fact it is the use of existing windows and the placement of a low-emission film between the two parts.
In this case, it is important to establish the necessary steps such as the determination of the current situation, the evaluation of the current situation, the creation of the targets, the selection of the criteria, and progressing in a solidarity.
The aim of sustainable design; aims to be capable of targeting itself to future generations with the help of data such as local materials, infrastructure, climate, technology, natural resources.
In this culture, which is based on the production of environmentally friendly structures, efficient energy use is provided and the cost is minimized. It tries to be suitable for the use of future generations with its own habitat without belonging to a certain age or time. It is always based on nature itself.
Sustainable structure of all materials to be used in its life cycle; construction, construction, use, disassembly, recycling, destruction and be at the risk of beating the effects of the pulse should aim to create reactions. We need to evaluate the effects of the structures we create with such approaches on the resources of our world. In today’s conditions we have the option of calculating the CO2 emission of the structures. Furthermore, there are many criteria such as sustainability grade and green construction documents for the structures.
For the coming periods, the construction sector is focused on building designs with high energy efficiency and low CO2 emissions. In EU countries, China and the UK, many laws have been studied to improve energy efficiency and reduce CO2 emissions. As an example, we can give England the opportunity to adopt the Climate Change Act in 2008 and aim to reduce CO2 emissions in structures by 26% to 2020 and to 80% by 2050, based on this law. Since 2016, all houses to be built in 2016 have to be built on zero carbon basis since 2018, as well as all public buildings and private sector buildings.
The EU has given priority to increasing energy efficiency and reducing CO2 emissions. The Regulation on Energy Efficiency in Buildings, prepared in 2002, aims to regulate the existing and new housing units on this issue and renew them every five years. Accordingly, starting from 2020, all new buildings have to be built according to the-almost zero-energy ar school. On buildings based on zero energy; Both energy consumption should be minimized and the energies needed should be provided from renewable energy sources.
