eco village design is a new field of knowledge still under development. it will be the physical manifestation of the unfolding of the ecovillage dream held by so many. it is generally agreed that concept of sustainability should play an increasing role in future urban development world-wide. in order to ensure ecological sustainability, cities around the world have to decrease their environment...

The efficiency of an airfoil can be improved by adjusting its surface. CFD software was used to investigate a 2D with and without spanwise semicircular groove on the upper NACA0012 airfoils grooves were analyzed using k-ω turbulence model. lift drag coefficients compared. To effect location efficiency, added in various locations compared smooth airfoil. flow velocity remained constant at 20 m/s...

Energy efficiency enhancement has become an increasingly important issue for battery electric vehicles. Even if it can be improved in many ways, the driver's driving pattern strongly influences the battery energy consumption of a vehicle. In this paper, eco assist techniques to simply implement an energy-efficient driving assistant system are introduced, including eco guide, eco control and eco...

There are various studies on the eco-innovation in the literature, but there is a scarcity of studies on the adoption and diffusion within manufacturing small and medium-size enterprises (SMEs). Drivers to adopt eco-innovations by manufacturing SMEs are required to be understood properly and be analyzed regarding the relationships among them. Hence, the purpose of this study is to identify the ...

Eco-innovation is any innovation that leads to sustainable development by limiting the negative impact of production activities on the environment, increasing the resilience of nature to loads or ensuring greater efficiency and responsibility in the use of natural resources. Eco-innovations are the opportunity for enterprises. Their introduction contributes to reducing the costs of doing busine...

Ecological (eco) taxes are promising mechanisms to enable eco-friendly decisions, but few people prefer them. In this study, we present a way in which eco-tax options may be communicated to general public to encourage their payment. Our implementation (called “information presentation”) takes advantage of the non-linear relationship between eco-tax payments and CO2 emissions and the human relia...

The computational study discusses the application of co-flow jet technique as a fluid flow control device on NACA 0015 airfoil. numerical equation used is RANS with k-ε turbulence model. There are three variations mesh proposed in this paper. first variation fine 100,000 elements. second medium 50,000 Meanwhile, third coarse 25,000 Based independence test results, lowest error value mesh. Co-fl...
