The Eco360 is a single-family four-bedroom home located north of Tel Aviv. The goal of the project designed by Geotectura was to build a sustainable home that would be Energy-Positive and include excellent indoor air and light quality while reflecting the beauty of the surroundings.
The challenge was even greater as the view of the sea is to the west, so traditional passive design solutions that are appropriate for the south façade were not valid in this case. An unusual geometrical optimization was needed to obtain all the passive design features while facing the west. The house is well insulated and is largely heated by the energy that is generated by body heat and household equipment.
The entire design team worked with BIM (Building Information Modeling) methodology using environmental simulations during the design process to reach the best optimization.
The client wanted to build a home that could demonstrate, highlight, and set an example of what could be done to build a home based on ecological principles, with minimal maintenance, using solar power, a grey water system, passive wind strategy, high durability and recycled materials.
The client’s hope is that the house will inspire others to consider ways in which they can also use these green principles in building and that it will serve as a model of efficiency and environmental sensitivity.
The house reveals and reflects the ideas of sustainability with more than fifty green design features. The hope is to raise awareness about green design challenges and solutions.
Simulations and local climate studies affected the design. The challenge was to strike a balance between the building orientation which would normally face the sun’s path from east to west with a long façade to the south and the need to face the sea in the west and orient the house accordingly. This necessitated blocking the morning and afternoon sunlight from hitting the glass or the wall beyond the ventilated facade.
Geometrical optimization to obtain minimal volume for the inner rooms with lower ceilings to save heating and cooling loads. The diagonal concrete structure is holding the mass.
Integrated Photovoltaic Panels
Photovoltaic array facing south and west for maximum solar exposure with 16.2 KWP system with 45 solar panels producing much more than double of the consumption demands. Each 360 Watt solar panel has up to a 19.3% efficiency rate.
Air flow window system that can be opened or closed according to the climate conditions, Upper windows let out the warm air and windows near the cooling water pool assist the passive cooling of the incoming air. During autumn and winter, the heavy-duty sliding doors system is especially fitted to block the intense winds coming from the sea direction.
The passive ventilation strategy started with a wind study of the site. Autodesk platforms can connect to meteorological data around the world and indicate the wind direction and temperature in different seasons and at different hours.
In the site there are good wind conditions that passively ventilate the project and reduce energy consumption.
The ventilated high-performance facades create an air chamber between the concrete structure and the bamboo-like cladding which generates a micro ventilation effect by convection leading to energy savings, acoustic insulation, thermal bridges, condensation prevention, and thermal insulation. Black marble on the upper parts are contributing to the Venturi effect by being warmer and stimulating the air exchange.
Smart House system with energy management
Intelligent Green Home system controls the dimmers, air conditioners, water heaters, shutters, media, sockets and more.
Biological water treatment system with Wet Lands
This system was designed to create a meditative space, with soft trickling sounds, fragrant inflorescence of the tropical water lilies, and a cool micro-climate created by the dripping ECOncrete wall with its ferns and mosses.
The Bio-Active wall composed of tiles and planter units was installed on the inner patio wall of the house. ECOncrete’s Bio-Active Wall Tile create a highly aesthetic green façade capable of reducing the overall ecological foot print of concrete walls by increasing plant diversity, improving air quality and energy efficiency, and reducing both noise and heat pollution.
100% BIM (Building Information Modeling) Teamwork
BIM is a 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure.
The BIM methodology allows architects, engineers, MEP consultants and more in the construction industry to design more quickly, more accurately, more ecologically and more economically. The fusion between BIM and the Information Age enable us to transform the endless data around into valuable information and to gain knowledge out of it during and after the design process. We are in the middle of a paradigm shift that made a fundamental change in the basic concepts and practice of architecture.
The BIM methodology was helpful with the conceptual energy analysis, detailed energy analysis, sustainable element tracking.
The energy improvements became finer as the project started to take shape and with more energy simulation tools.
