DIIRECT NORMAL IRRADIATION GLOBAL HORIZONTAL IRRADIATION PHOTOVOLTAIC POWER POTENTIAL

THE PATH

After locating the Project in Milan and setting Milan conditions, our goal is by using less effective solutions to provide efficiency equal to the most efficient solution. At this point, we tried to understand which solution is not the most efficient so we can work on it and make it equal to the other most efficient solutions

By following this idea, we have worked in the radiation sector At this point, we have realized that Radiation is not the biggest problem for Milan but it is still remarkable From this point, we decided to work on it; how we can get benefit from radiation, and how we can solve the problems which cause by radiation Due to work on this section, we have set the energy efficiency parameters of our building first then worked on problem definitions, re-engineering.

These analysis made because of potential problems and opportunities seen by radiation energy

• Direct Normal Irradiation: This analysis done to understand do we need a shading system

• Global Horizontal Irradiation: This analysis done to understand which kind of shading system we are going to use

• Photovoltaic Power Potential: This analysis was done to see how we can make equal solar energy efficiency to others

As a result;

• Since our South facade is clear, we decided to work on a shading system that will provide a comfort zone to the interior side. Due to work on the shading system, we re-engineered the current shadings by working on daylight analysis and radiation analysis.

• Since there is remarkable solar energy can be provided according to photovoltaic power potential analysis, we decided to work on solar energy systems as well Yet as it is seen from the analysis, we decided to work on new tech systems which can provide much more efficiency than other kinds of solar energy systems

DAYLIGHT ANALYSIS FOR EACH FLOOR

The Typology of the building is to optimize the indoor building performance regarding the user’s functions where it allows natural sunlight to enter the offices labs and corridors without overheating and creating uncomfortable environment

We analyzed the daylight analysis for the indoor spaces using Insight daylight that allowed us to study the performance and identify the critical areas of the of the building.

In the Southern façade we notice high Illumination and lower near the end side of the classed room than the required value.

In the Corridors the lux values varies from each area the requires to have artificial and natural lighting.

In service rooms where we have low luminosity the is the required to use artificial light to balance the lux needed for the space use.

The study reveals the entrance area where we have unbalance distribution of the illumination, where we have higher at the foyer and low luminosity this required to use artificial light to balance the lux needed for the space use.

In library we have the standard lux values for natural lighting during the day GSA

CALCULATIONS & RADIATION ANALYSIS

SHADING DIMENSION CALCULATIONS

Most Radiative Season

• Lasts for 3.4 months;

• From June 1 to September 13;

• With an average daily high temperature above 25°C;

• The hottest day of the year is July 26, with an average high of 30°C and low of 19°C.

Calculation Summary and Result

Inputs

By applying three main data: EPW File, Context:, Façade and Shading Configuration

Standard Calculations

By using standard calculations, the horizontal shading depth can be found

The Following shows the shading’s calculations set by the standards during the summer season.

Knowing that the latitude corresponding to the study case, the site in Milan latitude.

The value is ��=45.46° �������������� =sin 1[(cos��)cos(2345)cos 0 + sin(��)sin(2345)]=6799° �������������� =sin 1[(cos��)cos( 2345)cos 0 + sin(��)sin( 2345)]=2109°

The length P of the horizontal shading can then be found with the following formula:

�� = ��+��

Tan(αSummer) = 0.323

W : Height of the glass, considering the section between louvers (��=0.6 ����)

O : Distance between the window and the shading device (��=0.2 ����)

Effectiveness

Calculating the Ɛ effectiveness, to solve the reduction of the transmitted heat due to the presence of the shading system Where Ɛ effectiveness should be <030

We see the shading device performance coefficient in the critical season (summer) is lower than 0 3 which corresponds to the Italian code constrains Therefore, the effectiveness of the designed shading device is verified.

Least Radiative Season

• Lasts for 3.2 months;

• From November 19 to February 25;

• With an average daily high temperature below 10°C;

• The coldest day of the year is January 12, with an average low of -1°C and high of 6°C.

HOW

Concept

Shading decision is related to solar analysis After analysis the solar angles of Milano in winter and summer peak periods, it is clearly seen that there is a great difference between these angles In order to face with this kind of annual solar angle, Overhang

Shadings are offered It is a crucial element in passive solar design because it blocks the sun’s heat energy when it is not desired Since the sun travels different paths across the sky in the winter (low) and summer (high) time, an overhang can be constructed to utilize and manipulate the heat energy from the sun

In Summer;

• Keeps from summer sun

• Controls the light

• Prevents walls to act like thermal batt

COMPARISON OF INCLINATION OPTIONS AND REACHING THE RESULT

With the Actual Case, are able to see the higher daylight Intensity in the building with value 2x higher than the standard As well we notice the higher visibility to the interior around 6% as an average correspond to higher constant solar access during the day.

We analyzed Fixed shading with45DegreesSlopewesee higher reduction of the illumination intensity as we selected aluminum horizontal shading at has higher absorption and zero transmissionwhichcorelateto lower visibility during the day with average daylight within the standard requirements.

We have changed the Fixed shading with 10 Degrees Slope we see higher illumination compared to the pervious case we obtain higher visibility to the external environment and daylight average within the standard requirements.

Italy is located in the sunny Mediterranean region in the south of Europe, which is rich in solar energy resources and has great potential for development and utilization, and the cost of solar photovoltaic power generation is relatively low compared to the midwestern region of Europe

In addition, Italy is a relatively energy-poor country, most of the energy depends on imports from abroad According to data, Italy's domestic oil and gas production can only meet 4 5% and 22% of the domestic market demand, respectively, while nuclear power generation was rejected by a referendum

As a result, about 85% of energy imports make Italy's power generation costs remain high. The pressure of the energy crisis and the need for a low-carbon economy have led Italy to look to the clean energy sector, represented by solar energy.

As a result of the radiation analysis, solar energy production may highly increase energy performance of the building

There are several advantages of using solar energy system:

1 Renewable Energy Source

The most important thing is that solar energy is a truly renewable energy source It can be harnessed in all areas of the world and is available every day. We can not run out of solar energy, unlike some of the other sources of energy.

Impact on the Environment

Solar energy has the least negative impact on the environment compared to any other energy source It does not produce greenhouse gases and does not pollute the water It also requires very little water for its maintenance, unlike nuclear power plants for example, needing 20 times more water

3 Reduces Electricity Bills

Generating own electricity means that building will require less from the utility supplier This will immediately translate to savings on energy bills

4.

Low Maintenance Costs

The only thing that solar energy systems require is periodic light cleaning to make sure dirt, leaves, and other debris aren't obstructing the sun's rays

Solar Sphere

Design Solutions

Choosing a solar sphere logical not only for efficiency but also for design parameters. While solar spheres are providing %99 transparency, pv panels are blocking the vision and the view. With this advantages solar spheres, prove that solar system can be also used as a part of design. By the approach, it can be integrated to fundementals of building design.

Offering a solutions is not only related to efficiency, and design aspects More important than these parameteres there is a feasibility which allows or denies to apply the solution About this issue, solar spheres has remarkable advantages rather than other solutions. Firstly, solar spheres does not restricted by solar angles like panels affected. It can gather energy from everywhere from where light source or fake source. Moreover application of solar system is modular and can be applied to any kind of Project. Solar spheres not only related to roof only, it can be used in landscape design, facade solutions and etc due to its advantages Before applying this solution, we need to understand that it where it can be much more better Chart below is explaining where it is much more efficient than other areas

HOW DOES IT WORK?

Concept

To explain how it Works better, same solutions explained by differend kind of usage

The Spherical sun power generator

•Spherical solar power generator can work on both diffused or direct rays of the sun

•Diffused rays of the sun are directed towards ball lens

•Ball lens will focus the diffused ray onto a collector plate.

•This collector plate is small but as powerful as a larger PV panel

•Collected energy will be converted into electricity using that smaller PV panel and will directed towards the battery

•The spherical sun power generator has a dual axis tracking system with a micro tracking system,

•both the spherical solar power generator and tracking system are immune to weather.

•It will absorb a very little damage in the windy season.

•Collected energy in the battery can be used in electric cars or any solar driven appliance

•Spherical sun power generator can easily supply its energy to the power grid in the future

•Heat is the additional benefit of the spherical solar power generator

Future
