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. This is because solar power does not consume natural resources, are readily available and are naturally replenished. 2.1 How it works The building is laced with light sensitive cells called the photovoltaic cells that convert light from the sun into electricity. This electricity is then stored in a battery system that is used to power the lighting system and other appliances within the building. A sketch of the system is attached. 2.2 Advantages Using a solar powered lighting system in which solar power is used to generate the electricity for the building’s lighting ensures energy security by reducing dependency on fossil fuel or the national grid. As a result the company will enjoy price stability as photovoltaic cells are installed only once and have lifespan ranging from 20-30 years. With solar power there are no transmission costs as all the energy produced is consumed unlike other sources where the fuels have to be transported. It is therefore ideal even for places that cannot have access to the grid. Cost wise the solar panels are becoming cheaper and more efficient thus ensuring more value for money. It is also a very quite source of energy which is a great advantage of a service oriented company in which communication is key in its operation and a quiet working environment has a great impact. 2.3 Disadvantages Major disadvantage is the high cost of installation; it also requires a large area for installation. This can however be mitigated by incorporating a building design in which photovoltaic cells are positioned for optimal harvesting. The other disadvantage is that efficiency is dependant on the full exposure of the sun and may affect cloudy days. 3.0 Green Roof The company could consider using a green roof for the building. This is simply having a design that will ensure the entire roof of the proposed building would be covered in vegetation to form a sort of living roof. 3.1 How it works The roof is covered with vegetation that is grown over a waterproofing membrane. The membrane helps to prevent percolation of water and also root ...

Renewable energy is the energy that is generated from such natural resources as wind, rain, sunlight, geothermal heat and tides that can be replenished naturally. Approximately 16% of all energy that was consumed in the world was generated from these renewable sources. 3% came from new renewables like small hydro, wind and bio fuels
Renewable energy is also seen as a perfect example in fighting global warming. These sources of energy do not emit carbon monoxide into the air thus affecting the ozone layer. Further, renewable sources of energy are sustainable; they can be used for several years without being depleted.
The types of renewable energy include solar, wind, hydroelectric and wave power. Introduction Energy is the main driving force of nature and human civilization. The world is even known to have a high level of energy consumptions which even increased during the industrial revolution.
It aims at providing new, better ways of constructions that depends mostly on less energy, less raw material, little or no pollution and releases less waste. This ensures that the economic viability, safety and the comfort of the building is not compromised but optimized.
Renewable sources are discussed with emphasis on their potential impacts on the environment: Solar power can result in land wastage and release of hazardous material used for cleaning the semiconductors. Hydroelectric power on the other hand can also result in land wastage and the dams often result in depreciation of water levels and drying up of rivers drastically affecting aquatic life forms.
A large number of multinational companies publish environmental sustainability reports in fact it has become an integral part of the publication of multinational corporations. Majority of the companies are involved in struggles to integrate green initiatives into all of their business segments.
Eventually, efforts were directed towards energy conservation programs and alternative energy resources development. That’s how renewable energy came into existence up to today (Qurash & Hussain, 2010). In
The degree of the problems recently besetting the natural resources and environment reflects the significant social economic progress attained in the XX century. Sustainable development is progress that meets the requirements of the current generation without compromising the capability of future generations to satisfy their own necessities.
There are several enabling conditions for policy implementation. One opportunity is the effective enforcement of legislation. Weak law enforcement lowers long term investor and market confidence for most business to develop. The shift of
nd viability owing to geographical and geological complications the country faces which continue to negatively affect the sector (Martha and Ulfa, 2004).
