A cooperative is the sunniest renewable energy supplier in the Netherlands
Sustainable initiatives are fast spreading in the North of the Netherlands (Friesland, Groningen and Drenthe) where, in a grass roots way, they’re helping to achieve the transition to a sustainable society. NLD – Noordelijk Lokaal Duurzaam (Northern Local Sustainable) energy was created to support and accelerate the environmental ambitions of…
From tabula rasa to circular construction
Although Rem Koolhaas is still interested in “Tabula Rasa” processes it is good to know that he discuss preservation. But there is more to it, I’m afraid. We should not demolish not only usable buildings, but also reusable, repairable and recyclable ones! Partial demolitions should be welcomed and understood, but…
One of solar’s biggest problems about to be solved by Tesla Powerwall
Photovoltaic advocates and enthusiasts are now contemplated with what most knew was needed, a quality, efficient, affordable and scalable solution product that helps us deal with the seasonality of our Sun. At the size of a typical solar inverter hanged on a wall, the 10 kWh Tesla Powerwall battery module…
Micro and Mini energy generation stimulated by tax exemption in Brazil
The National Council of Finance Policy (CONFAZ), signed an ICMS exemption agreement (Link in portuguese) to encourage micro generation (<100kW) and mini generation (< 1 MW). ICMS is a tax that pertains to the circulation of goods, and providers of transportation and communications. As a state tax, it can vary…
Photovoltaics – Shadow analysis for one home
Besides an effective solar orientation and geographical position, a project to install photovoltaic panels is also challenged by physical impediments to sunlight like buildings, mountains and peripheral vegetation. The top of a tree can not be shadowing the installation location during the summer, where the sun has a more vertical…
Projects and visualization for solar pannels instalations – The Netherlands
In visual terms the positioning of solar panels, although relatively simple, may be a hindrance to clients concerned with the aesthetics and possible spatial discomfort caused by its installation. The illustrations below were requested as means to help the clients on clearing any doubts over the future viewable results. Invalid…
