Renewable Technologies 1.0 Wood fueled heating system. Installation of a wood fuelled heating system would be an appropriated technology to consider since it produces comparatively lesser carbon emissions hence reducing the building’s carbon footprint. 1.1 How it works The system uses large gasifying boilers which are loaded with seasoned logs that are then fired up to produce hot water…
Trees use energy tapped from the sun to fix carbon in the wood in a natural way and therefore are sustainable so long as harvesting can be done without depleting the woodland resources. Due to its nature wood fuel is virtually carbon neutral as the carbon dioxide emitted from burning is balanced by the carbon absorbed by growing trees. Wood is also a clean and safe compared to other fossil fuels like oil which are harmful to the environment in case of spills. The wood fuel gas is almost smoke free and its ash content is less than 1% which can be reused for other purposes. It will also benefit the social welfare of the entire community in that use of wood would ensure proper management of woodlands and promote local trade. By creating a ready market for wood fuel many jobs would be created to manage and ensure sustainable practice in managing woodland. The main disadvantage of this technology is that it has higher initial capital cost than conventional heating systems but in the building’s life-cycle costs. 2.0 Solar Powered Lighting System Use of photovoltaic cells in the building is one of the ways the company could use renewable energy sources for its operation without leaving a carbon foot print. ...
