The house was built in 1910. This means there are brick walls with poor to no insulation. The windows are also old which means that there is a great amount of heat loss through them as well as the passage of cold air into the house in the wintertime…

The design conditions for this house in southeast England are fairly neutral. There is a temperature variance throughout the year of 25 degrees Celsius. The temperature goes from, on average, 0 degrees Celsius in January up to around 25 degrees Celsius in the peak months of summer. Rainfall remains pretty constant throughout the year, ranging from 45-80 millimeters a month with the summer averages slightly lower than the winter ones. This house has eight rooms that require heat. The room that will require the greatest amount of heat is the living room. The living room is the largest room in the house and also has two windows which, in the wintertime, will be a major source for heat loss in that room. The bedrooms will not have as high of a demand for heat due to the fact that these rooms are smaller in size as well as one the upper level. Heat rises so they are naturally warmer than the downstairs. Bedroom one and bedroom two would require around the same amount of heat due to the fact that they are approximately the same size, in about the same location within the house, they have the same size windows and doorways, as well as the same number of occupants. The heating requirement for each room will vary based upon the size of the room, the location in the house, the number of windows, and the normal occupancy of the room. We will also need to take into consideration the insulation of the walls, ceiling, floors, and windows. Appliances also emit heat, but they are less trivial factors when compared to the ones stated above....
There have been laws enacted to help reduce the amount of fuel consumed by homes in England for
years now. In 1981 the Energy Conservation Act mandated that certain domestic appliances be labeled
as to their fuel efficiency. In 2000 the Warm Homes and Energy Conservation Act was passed and said
that Parliament will provide assistance to those who are fuel poor and upgarding to more fuel efficient
boilers and other such appliances. The latest and most current is the Energy White Paper (2003). The
Paper describes energy efficiency as "the cheapest, cleanest, and safest way of addressing our energy
policy objectives" (POSTnote, 2005). This Paper, in theory, will have dramatic potential for carbon
savings as well as reduced energy consumption. This Paper describes energy efficiency as the cheapest
and safest way to address our energy policy objectives.
The downfall to reduced costs of fuel with more energy efficient devices is that some people
take the savings as an opportunity to increase their energy usage. If energy is cheaper, then some
people can use more of it. This means that energy efficiency will not always produce reduced
consumption (Wilhite, 2004). The current legislation has helped to raise public awareness of the
problem. Before a lot of the public was unaware and therefore could do nothing to correct it. Now, the
public is made to be conscientious of the problem with the Building regulations and Acts passed within
the last few years.
Part L of the Building Regulations now mandates that any new installation of boilers in England
must consist of condensing boilers, unless there are extenuating circumstances. That is not the case with
the 1910 traditional mid-terrace house, so we ...Download file to see next pagesRead More

Renewable and Solar Power in the UK
...or not adopting measures based on renewable energy systems for improving their household energy performance and their experience. The data was gathered from 400 respondents to an online questionnaire made available during 2006 and 111 telephone based interviews. Solar thermal water heating and solar photovoltaics were not the only renewable energies considered as micro-wind turbines and wood-burning stoves were also included. The measures for energy efficiency were loft insulation, condensing boilers, heating controls and energy-efficient lighting. The main finding as to why people adopt renewable energy systems was that they do so to save on energy, on money and on the environment. The proportion of the...

Has the government successfully implemented low carbon refurbishment of the UK's existing housing stock
...which compromise the building’s permeability. Step 2. Secondly look at benign enhancement through improving heating strategies, controls and equipment.  For example, condensing boilers are highly efficient and combined with effective controls and programming can make substantial reductions in energy use with negligible impact on the character of the building. Step 3 The next step is to control draught/air infiltration throughout the building. Large amounts of energy can be lost through gaps in construction, and as a result will reduce the effectiveness of any  upgrading work which might have been carried out elsewhere on a building. For instance, start by repairing any cracks and holes in the...

Economics of Energy and Environment
.... Emission through buildings recognised to be reduced by 18%. This reduction has been linked tomore widespread adaptation of latest technological condensing boilers which are more efficient in saving energy and minimising release of harmful gases. In the UK, almost 60% of the houses are built using cavity wall with insulation for minimising energy loss and reducing heating costs. There also has been a reduction by 46% in the industrial sector in relation to the emission of GHG. Furthermore, in the agricultural and the transport sectors emission of GHG has been minimised. The progress made in these areas has been based on subsidising energy efficiency measures (such as insulation grants), demanding...

A small and efficient condensing boiler has been installed; it operates off the mains gas supply. In some houses it heats standard wall radiators, in others; under floor heating has been installed at the request of the owners. In other cases, wood burning stoves are fitted by some...

How does the rise of ethical consumers effect corporate social responsibility the United Kingdom government which has made the introduction of condensing boilers necessary for purification of water supply, and the French government is making ethical labelling mandatory. Revealing the extent to which consumer responsibilitites reach, pressure groups in the population argue that “people especially those in rich countries should worry about the cost to the environment of the manufacture of some goods and the use of others” (Sorrell & Hendry, 1994: 82). The pressure groups among the public emphasize that consumers should take into consideration the facts about wages and conditions of the people who make the products that they purchase. They also consider the cost in...

Helping Alleviate Climate Change: Strategies Used by the UK Construction Industry the construction industry regarding the potential effects of the new legislation. Thus, there are three factors to really take note of. The current government policies in the United Kingdom emphasize on the reduction of carbon dioxide emissions through a number of strategies. Through the help of local energy advice centres, energy being consumed by each building in the nation is assessed and monitored. In addition to this, campaigns to promote the use of energy efficient light bulbs and condensing boilers have also been developed. Every new house in the UK is also required to meet Part L regulations especially with regards to energy consumption. Thus, construction companies, their management teams...

Note taking by condensing Quinn's first nine chapters into notes
... Topic: This is a story of a man in solitary and existential search for deeper meaning and wisdom. Filled by frustration and an eternal reflection about how the world has been cruelly aspersed by rapid changes and developments, he wandered and wondered why these are attained at the cost of human’s marginalization, displacement and alienation from his own ecology. The quest for answers led him, strangely, to a Gorilla at a menagerie—who apparently became his wise, sage teacher. The discourse was made in such Socratic process The latter raise questions that brought searing pain; author lethargic irreversible realities about rejection; of the challenges of modern civilization. He realized this gorilla was able to develop... Topic: This is a...
