# GREENHOUSE GAS EMISSIONS

## Introduction

The calculator of Australian Greenhouse Gases helps the engineers with relevant insights regarding the construction of buildings that would help to comply with the threshold value of emission of Greenhouse gases in the country. Humankind is enjoying the benefits of advanced technology but there are some things that needed to be done to check the greenhouse effect. The Calculator of Greenhouse Gases is utilised for typical indicative reasons only. The estimates of emissions of greenhouse gases predicted by using this type of calculator are indicative and might vary with the actual emissions of the household. This case study would brief the approaches that the civil engineers need to undertake to consider the greenhouse emission critical value in Australia.

## Calculation of   greenhouse emissions from the provided existing household

As it can be observed from the graph, there is a significant difference between the emissions of greenhouse gases and the threshold value of it. This is only with respect to the transportation that the mentioned family utilises on a regular basis.

The concerned family are a bit too luxurious for the environment to afford, as they utilise their private transportation to reach their place of work. The significant amount of petroleum that is released in the air contributes heavily to these values.

As a result, the concerned people need to utilise public transportation or means of transport that does not aggravate the atmosphere. As they only afford air travelling only once a year, so the contributions they make while travelling in this aspect can be excused as the contributed value and the desired value are in close proximity.

## Suggestion of reduction of emission of greenhouse gases and keeping it below the threshold value

When transportation is considered, the concerned people need to utilise public transportation or means of transport that does not aggravate the atmosphere. As they only afford air travelling only once a year, so the contributions they make while travelling in this aspect can be excused as the contributed value and the desired value are in close proximity.

When the heating and cooling systems are considered, the thermostat temperature needs to be at a recommended value of 15 degree centigrade. In addition to this, four or five star latest appliances need to be bought that would comply with the environmental demands. The cooling system is also not suitable to be utilised anymore, but is used nonetheless for 4 hours throughout the entire day and contributing significantly with CFC gases. As a result, there is a significant difference between the actual values and recommended values in this regard. Hot water is generated in the household by utilising a geyser and solar energy is not at all utilised for this purpose. As a result, a considerable loss of energy takes place, thus creating a disparity between the actual and desired values of greenhouse gas emission (Tang et al. 2016).

The cooling system is also not suitable to be utilised anymore, but is used nonetheless for 4 hours throughout the entire day and contributing significantly with CFC gases. Mentioning Ren et al. (2013), their utilisations need to be minimised so that the CFC emission in nature does not surpass the threshold value.

In order to use the washing machines appropriately, a modern day appliance needs to be bought that would comply with the needs of the environment. Along with this, minimal water should be utilised and the utilisation of these devices should be reduced to the bare minimum.

When the aspect of lighting the household is considered, it utilises 18 halogens of low power to illuminate the house. The total luminescence power that is being provided is over 560 lumens of light per metre squared, which far exceeds the necessary luminous value of 150 per metre squared. Some lights can be turned off while other lights are sufficient to illuminate the house.

When the issue of refrigeration is being considered, an old device of 2 star rating and much less capacity is being utilised. This would result in the excessive emission of CFCs. Hence, to reduce the effect, modern day appliances need to be installed in the room that would take care of the harmful effects that are affecting the atmosphere.

Natural gas is utilised by the household and as a result, the difference between the emitted and desired value of greenhouse gases is almost equal. The slight difference takes place because of the usage of the microwave.

When other appliances are concerned, four laptops are operated daily for 4 hours each, along with a huge LCD TV which too runs for 4 hours every day. As a result, a considerable loss of energy takes place, thus creating a disparity between the actual and desired values of greenhouse gas emission. According to Nässén et al. (2015), each device needs to be utilised for a lesser amount of time and needs to be used without charging. In addition to this, the television needs to be utilised rarely and needs to be operated for minimal hours. Otherwise, the difference between the actual and desired values would only enhance in the end.

## Conclusion

The calculator of Australian Greenhouse Gases helps the engineers with relevant insights regarding the construction of buildings that would help to comply with the threshold value of emission of Greenhouse gases in the country. The benefits of advanced technology are being enjoyed by humanity but there are some things that needed to be done to check the greenhouse effect. The household needs to undertake some considerable changes in their lifestyle in order to carry out an exemplary life with respect to the environment. In order to achieve this, the household needs to start travelling via public transport to their workplace, or use private non-fuelled vehicles to travel. Most of the appliances that they utilise to carry out their daily operations can be considered backdated and are of the lowest quality, as can be judged from their rating. In order to comply with the Australian environmental standards, they need to realise the necessity of buying modern day environmental complied devices and utilise them as less as possible to sustain the environment in the end.
