Since a large portion of the total production of electricity comes from thermal power houses, the generation of electricity also adds to the high concentration of harmful gases in the environment. The UK government has set tougher targets for itself regarding the reduction in emissions and for this energy usage reforms must be introduced in buildings because energy use in buildings accounts for half of the overall CO2 emissions in UK. The reforms include promotion of energy efficient buildings and management of energy use in the existing buildings to improve efficiency. Ensuring energy efficiency in buildings starts from the design of buildings. There are numerous techniques which can be employed to make the design of a building energy efficient and the selection of most appropriate techniques is dictated by the climate of the region. The bulk of energy used in a building is consumed in air-conditioning therefore it is imperative to minimize the need of air-conditioning in order to lessen the use of energy in a building. The incorporation of natural ventilation and other passive means of air-conditioning in the design of building can considerably reduce the overall energy consumption; similarly daylight can be utilized to the maximum by proper positioning of windows. Control systems should be installed in buildings to monitor parameters like humidity and temperature and vary the speed of fans and pumps accordingly. Controls systems can also be employed for automatically switching off appliances which are left on unnecessarily. The energy efficiency of existing buildings can be improved by creating awareness among the occupants of the buildings about the various measures they can take to lessen the use of energy in the buildings; an efficient way of doing this is by providing energy efficiency manuals to the occupants as well as the maintenance engineers. Targets should be set up for reduction of energy usage in buildings and energy managers can be appointed to achieve these targets by properly governing the use of energy in large buildings. Energy efficient designs are also financially feasible because of the rapid payback to the initial investment offered by them in the form of lower running costs. The designers should provide energy efficient designs to the clients because in this way they achieve common good for all; the client, the occupants and the environment as well (CIBSE, 2003). The climatic conditions in the 21st century have changed considerably from the past and thus the design considerations for buildings must be changed accordingly. The global climatic change which started with the industrial revolution has resulted in global warming and the climate of various regions of the world today is different from as it was 50 years back and will continue to change in the coming years. The increasing temperature will require more air-conditioning in summer which will increase the concentration of greenhouse gases in the environment resulting in further increase in temperature and the process will continue to take place leading to the destruction of planet. Therefore decreasing the energy use for air-conditioning is the foremost requirement and this must be considered in the design of all sorts of buildings. Global warming will cause the temperature in winters to increase as well, thereby reducing the heating requirement and thus reducing the use of ene
1. The change in global climate is very often attributed to the increased concentration of gases emitted by the burning of fossil fuels. The amount of fossil fuels consumed today is highest in the history of Earth and this is because of the rapid developments in industries and the ever improving lifestyle of human beings…
Achieving Sustainable Development in Construction Introduction The construction industry has evolved into one of the powerful economic sectors in the country, given its immense contribution to the economy (Porritt, N.d). Due to this fact, the sector has become competitive and in the process, it has led to prosperity and growth of the economy.

This has significantly posed challenge to building engineers to integrate new designs and refurbishments approaches that are energy-efficient in order to reduce the consumption of energy whilst responding to external climate as well as providing comfort in the internal built environment.
Most energy sources involve burning of fossil fuels such as coal, and thermal energy, which have led to a heavy carbon burden in the environment. Increased carbon burden has led to the effects of global warming, as carbon emissions pile up to alarming levels with devastating effects in weather patterns and other weather related diseases.
There are also suggestions on how to select suitable heating and ventilation systems for each room taking into account their position within the building and the activities each is meant for. Lastly, there are suggestions on where to optimally place heat emitters, air supply/extract terminals, heating system boilers and ventilation system air handling units within the occupied area.
The proper utilization of natural systems and the social challenges of humanity highlight sustainability as an economy in equilibrium with basic ecological systems. There could be an emphasis on environmental, economic or socio-political sustainability and the need to have a sustainable ecological and natural system is important in any developmental scenario.
Building Surveying is one of the widest areas of surveying practice. The areas of surveying are basically about people, politics and places. In this paper we will discuss the about Building surveying, its importance, needs for Building surveying, importance of Building surveyor, Career opportunities in Building surveying.
To construct a two storey Villa in an1.25 acre area, in Turks and Caicos Islands, with a richly planted garden in the frontage, a private swimming pool closer to the main building, a servant apartment of 25 ft x 30 ft in the right corner of the premises, garage to park 3 big cars, providing a clear drive way around the building with a portico in the front.
Lightweight wood trusses are extremely cheap construction or building elements, which combine highly tough, light weight and cost saving elements of building (Malanga, 1995, p44). One of the most used lightweight trusses in the
