Moreover governments, civil society and industry organisations use information campaigns to increase awareness and knowledge of energy saving options in buildings. In other regions such as the United States and some Asian countries, there is a stronger focus on a combination of mandatory regulation such as the Energy Conversation Building Code for commercial buildings in India and voluntary labels e.
Insulation leads to energy savings, which reduce the demand for fossil fuels and associated GHG emissions and other environmental impacts. It is estimated that improvements in the level of insulation of the existing building stock can reduce heating requirements by a factor of two to four Levine et al. For countries with milder winters, where heating is still required, as is the case in many developing countries, modest levels of insulation at a reasonable cost may already reduce the heating requirements by more than half of current levels, and in addition may contribute to reducing indoor temperatures in summer Levine et al.
If there is no air conditioning, lower temperatures in summer improve indoor comfort, or, if air conditioning is used, lead to additional energy savings. The investment costs of insulating a building and the associated savings in energy costs play an important role in decisions on the level of insulation in a building. Table 2 shows average payback times for insulation measures added to existing buildings in the Netherlands.
Investment costs and payback times for different insulation measures differ significantly. Whilst in some cases investment costs can be high and payback times longer than 8 years, other insulation measures are among the most cost-efficient options for reducing energy costs in buildings and saving GHG emissions. As of January , there are 4 projects using this methodology in the CDM pipeline, one of which has been registered and CERs have been issued.

Retrofitting of existing buildings. Traditional building materials and design. Introduction By insulating a house, one can reduce the heat loss in buildings in cold weather or climate, and reduce a heat surplus in warmer weather or climate.
Below insulation measures for residential buildings are described: Wall, roof and attic, floor and soil insulation Wall, roof and floor insulation may be done by fixing insulation material to the wall, roof or floor, either on the inside of outside, e. Window and door insulation Windows and exterior doors have a large impact on the heating and cooling requirements of a building.
Feasibility of technology and operational necessities Increasing insulation is technically feasible for almost all buildings, although it is most efficient to add insulation during the construction phase.
Figure 1 shows the potential energy savings, costs and barriers for different types of insulation measures Common barriers why these measures are not implemented include: high initial investment costs, lack of financing options for the up-front investments, the time and effort required to undertake renovation measures in existing buildings, relatively long payback times for some measures, lacking knowledge and awareness, and split incentives, i.
How the technology could contribute to socio-economic development and environmental protection Insulation leads to energy savings, which reduce the demand for fossil fuels and associated GHG emissions and other environmental impacts.
Financial requirements and costs The investment costs of insulating a building and the associated savings in energy costs play an important role in decisions on the level of insulation in a building.
However, frequently homeowners are not aware of the economic benefits of insulation measures. References Levine, M. Blok, L. Geng, D. Harvey, S. But a building built just to code is only meeting the legal minimum, not delivering customer value beyond that baseline. Designing and constructing beyond code—including quality residential insulation installation—delivers buildings that are more energy efficient, quieter and healthier, which can give you a competitive advantage.
The value of energy efficiency is obvious: it saves homeowners money on energy bills and reduces power plant CO 2 emissions to lower carbon footprints. Energy efficiency is becoming increasingly important to homeowners. In research by the National Association of Home Builders: Of the top 15 features builders plan to offer, 3 relate to energy efficiency:.
Noise can come from outside sirens, traffic, neighbors or within children, TVs, music etc. Trending preferences for open concept houses with fewer walls or noisier urban locations are making homes built to minimize sound more popular than ever before.
This material is much smaller and more flexible than rolled batting, so it can get into smaller spaces and fill cracks and openings more effectively. It also fills in around beams, pipes, and other oddly shaped objects. It is moisture resistant, which helps prevent the growth of mold and mildew. The most important location in your home to have high quality insulation is in the attic.
Hot air rises, so in the winter, when you have heat pumping through your house, a lot of that air is able to escape through the roof via the attic. In the summer, on the other hand, heat is able to seep into your home through the roof and attic.
This can make you uncomfortably warm, tempting you to crank up the air conditioner and drive up your energy bills. In addition to saving money and energy, upgrading to good insulation in your attic can help protect against moisture penetration. This helps to deter mold, odor, and rot, which can be very dangerous to your health and damaging to your home. Good insulation will save you money and decrease your use of limited energy resources.
It will also help to keep you comfortable by creating more uniform temperatures and less draft throughout your home. It will provide a buffer against noise throughout the house and from your neighbors. Finally, it will keep your home cooler in the summer and warmer in the winter to create a more enjoyable environment year-round.
