CHAPTER 2 EVALUATION AND IMPROVEMENT

2.1 Idea for improvement:

Traditional high pressure light systems rely on electrical energy from the grid, which can be costly and have a significant carbon footprint To address these concerns, we have developed a groundbreaking solution that integrates solar panels directly into the high-pressure light system, enabling it to operate using renewable energy from the sun

The solar panels are strategically incorporated into the design of the high-pressure light system to capture sunlight and convert it into electricity These panels consist

of photovoltaic cells that generate direct current (DC) power when exposed to sunlight

By harnessing solar energy, the improved high pressure light system offers several notable advantages:

Sustainability: Solar-powered high pressure light significantly reduces reliance on non-renewable energy sources, minimizing carbon emissions and contributing to a greener and more sustainable future

Cost-Efficiency: By utilizing solar energy, the operational costs of high pressure light systems are substantially reduced Once the initial investment

in solar panels and energy storage is made, the ongoing cost of electricity is eliminated or significantly minimized

Independence: Solar-powered high pressure light systems provide independence from the electrical grid, making them suitable for remote or off-grid locations where access to electricity may be limited or unreliable Versatility: The improved high pressure light system retains the versatility and adaptability of traditional high pressure light, making it suitable for a wide range of applications, including outdoor lighting, horticulture, industrial and commercial lighting, photography, and specialized industrial processes

The integration of solar energy with high pressure light technology represents a significant advancement in the quest for sustainable and efficient lighting solutions As solar technology continues to evolve and improve, solar-powered high pressure light systems have the potential to play a crucial role in illuminating our world while minimizing our environmental impact

CHAPTER 3 ENVIRONMENTAL IMPACTS OF PRODUCTS 3.1 Environmental impact calculation tool

Ecolizer 2 0 is an innovative tool that helps users calculate and understand the environmental impact of their daily activities It provides an in-depth analysis of the user's carbon footprint, water usage and energy consumption With the help of Ecolizer 2.0, users can identify the areas in which they can make the most impactful environmental changes and make better decisions for a greener future

Fig 4 Ecolizer 2.0 tool

The Ecolizer 2.0 is primarily a tool for designers, helping them toassess

environmental product impact and to choose the proper material for each individual application It is a first step towards ecodesign, but not the only one Defining a life cycle scenario and determining a functional unit of your

product/design are particularly important when using the Ecolizer For some, the Ecolizer will prove too complex and time-consuming, for others it may not be sophisticated enough Alternatives are available to fulfil the needs of both types of users

Ecolizer can be used for different material such as: plastics, wood or metal,… and also canculate the engergy, transport, lights, and electronics components 3.2 Evaluate the effectiveness of changing material

Hypothesis: To make the 2 products fair, we need some assumptions to make the 2 products about the same frame of reference so that we can get the most accurate calculations with ecolizer 2.0 First, there is no ecolizer for Vietnam, but only for Europe, so we will use European standards to calculate

In this case, we consider the improved high-pressure and high-pressure streetlights

to be manufactured at Hapulico's factory - Hapulico company has always been one of the leading units in the field of design, construction of lighting works and manufacture of lighting equipment Hapulico is the unit assigned to manage the lighting system in Hanoi city and is also the first unit to produce urban lighting equipment: columns, lights Currently, the company's factories are located in Van Lam - Hung Yen and Kieu Ki - Gia Lam Therefore, we consider the transportation distance and means of transportation from the factory and the place of installation

of both products to be the same, so we will skip the transportation phase

In the end, we will assume 2 products are used for 12 years, 1 time a day, 12 hours each time

In short, the product is compared with the following assumptions:

Use European standards ecolizer to calculate

Both devices are manufactured in the same factory, so we consider their distance and means of transportation to be the same Therefore, we will skip the transportation phase

2 products are used for 12 years, 1 time a day, 12 hours each time

In order to see the advantage and disadvantage, we apply Ecolizer 2.0 in 3 phase: Production, Consumption and Recycling With the assumption given above that

2 products have been brought to the same frame of reference; we will use the method of simultaneous comparison

As mentioned in chapter 2, we have the main components of high-pressure streetlights as figure below We should analyze each component and calculate the sum of them in order to take total results

Fig 5 3D model of improved high-pressure street lights

3.2.1 Production phase

We consider common installation equipment such as lamp poles, brackets of both normal and improved devices to be the same Therefore, we will exclude the components from the calculation

We have Ecolizer calculation:

From the chart, we have some comments:

Overview, improved equipment will have more components, thereby increasing the environmental impact significantly

3.2.2 Consumption phase

We calculate in a period of 12 years of use, used once a day, each time using 12 hours from 6 pm to 6 am For ordinary high-pressure streetlights, 150W type is used

We have Ecolizer calculation:

Table 3: Consumption phase of simple high-pressure streetlights.

We assuming that 1 year has 3/4 of the time there is enough sunshine to power the light bulb and the remaining 1/4 time will use normal electrical energy

We have Ecolizer calculation:

Total = 86724mPt

Since using solar energy for lighting, the improved high-pressure streetlights are completely environmentally friendly, so the impact on the environment is trivial

From the chart, we have some comments:

Because of its environmental friendliness, solar streetlights have reduced a large amount of impact on the environment compared to conventional light

3.2.3 Recycle phase.

Combining the data from 2 phase Production and Consumption, we get the Recycle phase:

After a period of use, ordinary high-pressure street lamps are completely discarded and cannot be recycled for continued use So in this phase, the environmental friendliness of this device is zero

Meanwhile, for the improved high-pressure street lamps, after a period of use, the solar collector can be completely reused I think, the battery can also

be recycled, but in Ecolizer 2.0 there is no mention of this factor, so we will ignore it

Table 4: Recycle phase of the improved high-pressure streetlight From the chart below, we have some comments:

One of the other outstanding advantages of the improved solar high-pressure streetlight is that it also has the ability to recycle expired materials The sign (-) here represents the reuse of the material
