Renewable Energy.

Renewable energy is normally defined as energy being obtained from natural resources that are permanently replaced by nature cycles. This energy, if exploited, can be useful to humans. Renewable energy is generally harnessed for sources such as the sun, wind and tides. Nowadays, the government and local authorities are encouraging the use of renewable technologies due to its obligations to reduce CO₂ emissions as signatories to the Kyoto Protocol.

Government Targets.

Under the Kyoto Protocol, which is an official binding agreement and having legally signed to this protocol, the U.K is required to reduce its greenhouse gas emissions by at least 12.5% below the 1990 level in 4 years, from 2008 – 2012.

The Kyoto protocol also allows “Emissions Trading” which is a method whereby countries are permitted to buy and sell greenhouse gases ‘Units and Credits’.

BUILDING OPTIMISATION STRATEGIES:

The design of buildings is a multi-criterion optimisation problem, there always being a trade-off to be made between capital expenditure, operating cost, and occupant thermal comfort.

Thermal Mass.

The thermal mass of a building is normally defined as its ability to store heat. This has an influence on the operating temperature within a building by stabilising the internal temperature.

Diurnal variations of the outside temperature (ϴo) result in heat flows into the building during the day. This heat is stored in the material and released to the environment at night.

The higher the thermal mass, the greater the time lag and hence, the smaller will be the decrement factor between the internal and external temperatures (Ti _maxand To _max) . This method is normally applied by using Fibre Cement Boards, Plywood and other available products..

What Ventilation System can i choose for my kitchen ?

Ventilation is the process by which fresh air is provided to occupants and by which concentrations of potentially harmful pollutants are diluted and removed from a space.

Heat recovery ventilation (HRV) is a system that employs a counter-flow heat exchanger between the internal and external airflow. This type of ventilation system would provide fresh air and an improved climate control if it was to be applied as the ventilation delivery system for the kitchens within a building.

Depending on the model installed, HRV systems can recover up to 85% of the heat in the outgoing air stream hence making them far more energy efficient than letting air in and out through windows. In addition, the system will normally filter the incoming air to prevent any particulates such as pollen or dust.
