Groundswell Community Network in British Columbia, Canada have constructed a passive solar greenhouse that greatly extends the growing season for a wide range of crops and reduces energy consumption to a minimum. The north side of the building is insulated and built with a high thermal mass to store heat and the glazed structure is placed on the south side. Surplus heat collected during the day is feed into a heat store beneath the floor. There are also photo-voltaic and solar thermal panels … Read more
Eco Retrofitting Older Houses Refurbishing Houses for Low Carbon Emissions
Buildings are the largest consumers of energy and worldwide there is a vast stock of old and highly inefficient homes and commercial properties. Bringing them up to modern ecological standards is a skilled matter involving insulating the structure, correctly ventilating the spaces and recovering heat from exhaust air, installing the most efficient heating systems with the lowest carbon emissions and fitting appropriate renewable energy systems such as photo-voltaic panels. The links below … Read more
Copenhagen – Cycle City Bicycle - The Way to Traverse the City
The city of Copenhagen has been planned and developed for cyclists with dedicated bike lanes and cycle paths, synchronized traffic signals and a wide spread general provision for bikes. Hundreds of thousand of cycle journeys are made every day easing congestion and pollution. Without the bicycle Copenhagen would be grid locked. Many other cities are also planning for bicycle routes but Copenhagen has done more successfully than most. … Read more

Solar Dryer for Food Sovereignty Sustainability all year round
The solar dryer is a solar-powered food dehydrator, that is entirely autonomous and “off grid”, and supports both local food autonomy and economic resilience. Once installed, it enables a farm to preserve seasonal surpluses of fruits and vegetables (which is a local traditional practice). This basic “tunnel” solar dryer is essentially a table-top greenhouse, with active ventilation provided by electric fans and a dedicated photovoltaic panel. It provides optimal airflow and temperature for … Read more
Composting Toilet Saving water. Producing compost.
In the Palestinian Territories the access to water is largely controlled by Israel, which makes it a very expensive resource, and not always reliable. The same happens with the access to land where it is possible to farm. Composting toilets can definitely reduce the amount of water needed per family, and they can also produce good quality compost that can seriously improve the soil's quality in a short amount of time. A composting toilet can be built largely with recovered materials. The … Read more
Building with Natural Materials Inspirational Ideas for Building with Natural Materials
Modern building has become a sophisticated process using highly processed materials and fittings that are part of a huge global industry. Reclaiming power on a local sustainable level and respecting what our local environments can give encourages us to use natural materials from our surroundings. Built to express the local landscape and local traditions such building generally harmonises with the environment and feels a part of it. It should be noted that natural insulation materials are less … Read more
Making roads ice-free Clearing the road with green alternatives to the salt, sand and chemicals
Cold-climate researchers at Washington State University are clearing the road with green alternatives to the salt, sand and chemicals typically used for highway snow and ice control. One of these alternatives is using leftover barley residue from vodka distilleries. … Read more
Billboards that clean air Hong Kong experiments with billboards that clean the air.
Designers in China have developed a concept for “parasitic robots” (they look like insects) which attach to city billboards to suck in carbon dioxide and purify the air. The company Fast Co Exist has developed these robots and is hoping to attach them to the neon signs in Hong Kong, where they would collect urban pollution in the daytime and use the heat from the neon lighting at night to harvest the carbon dioxide into an energy source. … Read more
