house construction 8 ecosystem support elements pose a significant ecological issue. At minimum, the Jetty should be made of materials that are non-toxic to aquatic organisms. Above the jetty, we are recommending planting vertical gardens and arches. Plants would either be decorative or edible and installed as the jetties are completed. HOUSEBOATS We recommend integrating tiles that offer habitat for birds. For boats without greenhouses, structures like bird houses and greenroofs should be installed to support additional biodiversity. OVERALL BIODIVERSITY WATERWAY Floating gardens will be placed around the site providing a habitats for insects and other animals. Some households have expressed a desire to keep bees. These floating areas would provide extra flowers for the bees to pollinate and offer additional aesthetic qualities to the site. JETTY The shading effects of a jetty have ecological impacts, but in such a shallow area with minimal plant growth, such shading does not Any urban infrastructure inevitably has a footprint. By integrating ecological elements into the system, Schoonschip can be designed to provide habitats, optimize on-site food production, maintain migration corridors, and de-nutrify the river IJ. Floating platforms with flowering plants will be placed in the channels between the boats, attracting pollinating insects. Boats have roof and wall tiles that provide habitats for bats and nesting space for water fowl. Floating platforms in the water provide added habitat for fish and crustaceans. The jetty is sloped and considers light penetration, integrating it with the ecology underneath. COST & LABOR ESTIMATES Biodiversity elements for houses are available 78 / 146 The plan that we are recommending can be scaled down or up depending on the financial capacity of each family. It is possible, for instance, to make smaller initial investments and achieve slightly less than passive house standard. The costs will be smaller up-front but will provide less savings in energy costs month aſter month. The DIY approach means that each of the technologies we are recommending will cost at least half of the commercial version of the technology, and in some cases as little as 1/10th of a commercial version. as retail products from companies like Vivara. To keep costs low, we recommend home made elements, which can be negligible in cost. 9 financial viability Pagina 77
