How to be more Energy Efficient

How to be more Energy Efficient

It is very likely that your home may be losing heat and energy without you noticing.

Buildings typically lose heat through windows, floor gaps, roofs and walls, as heat energy is transferred through them by conduction. Cold air for instance, usually enters the house through the gaps, doorways and windows, produce convection currents and push the heat towards the roof tiles and windows.

An general estimate of over 25% from the heat produced by your boiler will most likely escape through the roof at fast rates, without the opportunity to settle and warm the property as it would be expected to.

Furthermore, over 35% of the heat will escape through walls and gaps, in and around windows and doors, and nearly 10% of heat will disappear through the floor.

Altogether, the roof, walls, windows, doors and the floor are known as the thermal envelope.

If you can slow this movement of heat from inside the house, through the thermal envelope, to the external environment, you can significantly reduce your energy costs.

 

Saving on Heat Expenses by reducing Heat Loss

If heat loss can be reduced, your consumption of fuel will also decrease, resulting in savings for your household.

This is also helpful from an environmental perspective, as there will be less carbon dioxide released into the atmosphere, therefore supporting the reduction of greenhouse gases associated with climate change.

There are various ways to reduce heat loss and save energy:

Man insulating a wall within a home.

The most simplistic methods can involve using fitting carpets, curtains and draught excluders. Fitting reflective foil within, or on the walls, can also be a cost-effective and very useful method.

Heat loss through walls can be reduced by double glazing or insulated glazing – windows with two panes of glass that help minimising heat release as well as serve with outside noise reduction.

Heat Loss through walls can be reduced using cavity wall insulation – and insulating material which is placed into the gaps between the brick and inside wall. This will reduce convection on the outside of the home.

Loft insulation in the roof space is considered the best approach for energy efficiency in the home – being really cheap, easy to do and the payback can be reached within two years.

Walls typically come in two forms – solid and cavity walls.

Properties built prior to 1930 will generally have solid walls, whilst some houses built after this period are likely to have some form of cavity in the walls. Cavity walls are very easy to insulate – they can be injected with insulating material, which slows the movement of heat across it. This is cheap and well worth doing, again with a relatively quick payback – however a professional will need to install this for you.

Utilities bill

Good quality insulating will help conserve heat energy within the building and release less energy into the environment, causing less pollution.

Homeowners that want to aim for minimal heat consumption may want to opt for insulation, double glazing windows and covering gaps (around doors or other areas) in order to save money in medium to long term whilst better protecting the environment.

What is Fuel Poverty and how can it be alleviated?

What is Fuel Poverty and how can it be alleviated?

Although fuel poverty is defined and measured slightly differently across the UK, it is typically associated with families from the lower economic spectrum that are financially challenged by the utilities costs that are expended on warming the home.

In England, families that find themselves with residual incomes below the poverty threshold after covering the fuel expenses, or, experience fuel costs that are above the national median level, are considered to suffer from fuel poverty, according to the Low-Income High Cost (LIHC) metric.

In Scotland, households that experience fuel poverty are those whose utilities costs are above 10% than the households adjusted income. For households receiving social benefits and find themselves without enough financial resources to maintain an “acceptable standard of living” after covering the fuel expenses, are also considered to be experiencing fuel poverty.

Similar criteria are present also in Wales, where the 10% rules also apply but moreover, when families spend more than 20% of their household income on fuelling their home, they are classified as being in severe fuel poverty.

Risks and Main Contributing Factors

There are various factors contribute to fuel poverty, some that involve the individual or household, whilst some relate to the house or property itself. Risk factors associated with individual households can involve things such as: low income, unemployment, high fuel costs, fuel payment methods, young age (16-25), senior age (65+) and individuals with medical conditions.

Property related risk factors could be the age, size and state of repair of the property. The quality and amount of insulation in the property. The properties construction type and the efficiency of it’s heating system as well as type of tenure can also have a significant impact on fuel poverty in the household.

Statistics & Demographics

In 2018, England reported that 2.4 million (10.3%) of its households are classified as fuel poor, whilst Scotland and Wales identified 619,000 and 155,000 households, respectively, that experience fuel poverty. In the West Midlands alone, households classified as fuel poor are well in excess of 300,000.

Furthermore, the current pandemic is likely to have increased these figures further across the country.

Typical Characteristics of Fuel Poverty

 

What you may hear:

  • Home is usually too cold/ draughty.
  • The householders have respiratory problems.
  • The fuel bills are too high.
  • They are getting into fuel debt.
  • The householders stay in bed to keep warm.
  • The householder/s may wish to stay in hospital because it is more comfortable.
  • They have moved over to a prepayment meter to avoid incurring debt.

 

What you may feel:

  • Cold.
  • Large differences in temperatures between rooms.
  • Your hands might be cold to the touch.
  • You might smell Damp.
  • Sense of gloom and a depressed atmosphere.

 

What you may see:

  • Children constantly have runny noses, rashes, ear infections, conjunctivitis.
  • Children often off school.
  • Children are emotional/ tired.
  • Mould stains on walls or curtains.
  • Peeling wallpaper or paint.
  • Ventilation points blocked.
  • Householder wearing too much clothing.

 

What you may notice about the heating:

  • Portable bottled gas heaters.
  • Partial or no fixed heating system.
  • Heating controls absent / not working / switchedoff.
  • Visual evidence that heating appliances are not in use.

Health Implications

Fuel poverty can have a diverse set of health implications depending on either household temperature or the cleanliness of the household.

Cold Weather Plan for England have suggested that low indoor temperature present a range of health-related risks caused by fuel poverty such as: heart attacks/strokes, respiratory disease, influenza, worsening of existing health conditions or slower recoveries, falls/injuries, hypothermia, development of mental health illnesses, carbon monoxide poisoning, poorer nutrition.

To avoid such risks, homes should be kept at a temperature of 18*C-24*C (64*F-75*F). Home temperatures that drop below 16*C (61*F) present diminished resistance to respiratory infections. When temperatures are below 12*C (54*F) they affect body temperatures and increase blood pressure and viscosity, whereas when homes are warmed at bellow 5*C (41*F), a significant risk of hypothermia is present.

In terms of damp and mould in the household, they can enhance the risk of respiratory infections, runny nose, itchy eyes, cough, rhinitis, as well as reducing the resistance to bacteria and viruses.

Summary

Although there are various factors that contribute to fuel poverty, the three main causes that would also require the most attention are the high costs of fuel, low income, but also poor energy efficiency. It is the combination of these factors that place various householders in difficult conditions and lead to physical and mental health problems.

Potential Solutions

In an attempt to understand and help overcome factors that can cause fuel poverty, a series of solutions and ideas have been initialised by the British Government, as well as other (non-profit) organisations, such as Warmer Homes West Midlands.

Several of these solutions are listed below:
