Aluminum profiles A-W-67T // All the

openings' frames are made with separate

internal and external extrusion aluminum

profiles. The inner and outer aluminum

frames are separated internally (and

invisibly) by high-strength polyamide profiles.

The spacers keep the inside and outside

frames insulated from one another and

blocks the thermal bridges.

SolarBan 70xl // Solar control, low-e glass that combines the clear appearance of

transparent, color-neutral glass with high solar control and visible light transmittance.

Seasons Window // The system uses an innovative reversible frame, incorporating two

glazing assemblies: clear glazing to provide a weatherproof seal, and tinted glazing to

provide solar control. The two glazing assemblies and a ventilated channel between them

rotate together through 180o to enable a transformation from the winter mode, where the

tinted glass is on the interior, to the summer mode, where it is on the exterior.

Solar Or BIPV (Building Integrated

Photovoltaic) Module // Designed for

climate control and vertical solar energy

harvesting, combining energy production

with heat insulation, sun protection and

robust structure together with aesthetic

ambient effect. The core of the module

is a three dimensional shape prism.

Installed as the east and west windows.

Pythagoras Solar // Photovoltaic glass

units (PVGUs), or more simply solar

windows, are designed to replace

conventional insulated glass units in

curtain wall, window and skylight

systems. The product simultaneously

provides energy efficiency, solar energy

generation, and optimized day lighting.

Solar Edge Single Phase Inverters and Optimizers // Three-fold architecture consists of:

Power optimizers which perform module-level MPPT. A highly-optimized

algorithm ensures that each module is constantly kept at maximum power point

(MPP), preventing energy losses due to module mismatch or partial shading

conditions.

Fixed String Voltage - A highly reliable solar PV inverter. A unique Solar Edge

innovation, the string’s voltage is maintained at a fixed optimal point for DC to AC

inversion, regardless of a strings length or environmental conditions.

Advanced Power-Line-Communication - A portal for module-level monitoring and

yield assurance. All power optimizers continuously measure and communicate a

range of module-specific status indicators.

The power optimizer is connected by installers to each PV module or embedded by module

manufacturers, replacing the traditional solar junction box.

TIGI Solar Thermal Heating System // Honeycomb Collector which is a new type of solar thermal collector targeting high temperature differential applications. TI At the heart of the Honeycomb Collector is a polymer-made layer of transparent insulation, allowing for energy to enter the collector and heat the absorber plate.

1. Sunlight passes through the Transparent Insulation, heating the energy collecting surface.

2. The Transparent Insulation layer suppresses convection heat losses

3. The Transparent Insulation layer provides high resistance to thermal back-radiation

4. The result is a system with very high energy-efficiency, allowing energy to enter freely but limiting energy losses to a minimum

Honeycomb Collectors are extremely efficient in high temperature differences – heating water to high temperature differential from ambient. Hot water generated by TIGI’s products can therefore also be used to serve space heating or industrial process heat as well as to cool spaces in the summertime such as with the Linum System for cooling and heating which is used in the project.

Traditional air conditioning cycle // the most energetically wasteful element is the

compressor and actually this is the way we evaluate the COP (coefficient of performance)

which is a measure that can point us to the energy efficiency of the air conditioner. We know

that the higher the value of the COP, the better the output of the air conditioning system.

Solar Cooling // The house will use a solar hybrid air conditioning system by Linum Systems

which incorporates a thermodynamic cycle that produces cooling or heating. The cycle can

be powered by either solar thermal energy (in the form of heat) or electricity, or by both. The

air conditioner can be driven from high performance TIGI Solar Thermal Honeycomb

collectors producing hot water at temperatures of 100 ‐ 120°C. The steam is responsible to

change the refrigerant from liquid to super-heated gas in order to drive a turbine which is

responsible for operating the compressor. In this way we can minimize the use of electric

compressor and save large amounts of energy. In the house, the indoor unit is very similar to

any standard air conditioning indoor unit.

The use of these Thermal Solar flat panels turns installation of the solar collectors into a cost‐

effective and straightforward process, which can be carried out routinely throughout the world.

In order to reduce the energy consumption of the house, it is clear that if we are able to store the cold temperatures of the night, by night cooling radiation, we will be able to extend the time during which the energy-saving air conditioning method is used, and we will be able to stay within the required temperature comfort zone using a smaller amount of energy.

Heliocol - Magen Eco Energy - Night Radiative Cooling // In order to cool the cold thermal storage tank, the house will circulate cold water through a solar collector array. The optimal cooling potential can be achieved on clear nights, in which the cooling achieved could be 2-3 C below ambient temperatures.

"Energy Packs" - PCM (Phase Changing

Material) Energy Storage System //

A substance with a specific melting or

solidifying temperature, which is capable of

storing and releasing large amounts of

energy. This system is planned to store and

release energy, by using a solid-liquid cycle.

The Solar Decathlon competition challenges 20 student-led teams to design, build,

and operate solar-powered houses that produce at least as much as energy as they use,

while being affordable, livable, and attractive. The winner of the competition is the team that

best blends cost-effectiveness, consumer appeal and design excellence with optimal energy

production and maximum efficiency.

The Solar Decathlon demonstrates innovation in solar and sustainable architecture and

identifies immediately viable technologies. The first competition was held in the United

States in 2002 and it has been held biennially since 2005, with additional competitions in

Europe in 2010 and 2012.

In August 2013, Solar Decathlon China takes place in Datong, China, hosted by the Chinese

National Energy Administration and the U.S. Department of Energy. Team Israel, the first

Israeli team to take part in a Solar Decathlon competition, will construct and operate its

prototype house, competing in ten contests assessing everything from the house's

architectural style and market appeal to the ability of its residents to cook, do laundry and

entertain while conserving energy.

The group's approximately thirty students hail from the fields of architecture, engineering,

interior and industrial design, and environmental studies, supervised by two academic

supervisors, both architects specializing in sustainable design. In addition, the team has

created a large network of academic, government and industry partners. The project's

position at the cutting-edge of sustainable building technologies has garnered extensive

partnerships and industry support.

Team Israel is made up of students from four leading colleges and universities in

Israel incorporating future architects, engineers, and designers: Shenkar College of

Engineering & Design, Tel Aviv University, the College of Management Academic Studies,

and the Neri Bloomfield School of Design. We are proud to be the first Israeli team to

participate in a Solar Decathlon competition.

Our design agenda reflects Israel's dynamic culture, social values and sun-blessed climate.

Participating in the competition is an opportunity for us to demonstrate professional and

social responsibility by presenting a building which aims to be low budget while maintaining

a high standard of architectural and energy design.
