Insulation, Sealing Air Leaks - A Green Remodel to help Cut Power Bills

How would you like to dramatically slash your electricity bill as much as 85%? Superinsulating a house can significantly enhance the energy performance of an old house. These so-called  deep energy retrofits achieve household energy as much as 85% by addressing all (or almost all) energy loads - space conditioning, warm water, lighting, home appliances, and plug loads - or even transportation. Energy cutbacks of this magnitude require a rigorous and extensive systems approach: The natural associations among energy, indoor quality of air, sturdiness, and thermal comfort should be honored throughout construction and designs. Passive photo voltaic design and renewable energy systems are typical during these projects.
The objectives of any house energy retrofit can be like those of a brand new green residence, however like all remodels, a big difference is basically you have to deal with a pre-existing building. Below are a few house systems with particular areas you should focus on.
1. Upgrade Your Home's Windows

With the top and bottom of the home sealed tightly and insulated, the very next prospect will be the walls. Did you know that old 
and outdated windows is like having a significant hole in your wall? While functioning poorly, they often leak both water and air into the house. Correctly mounted, Energy Star (or even better) windows seal off the gaps in the walls to hold out water and climate extremes.
2. Modernize The Mechanical Equipment

A classic heater or central heating boiler is frequently the worst energy user within an old house. Many houses built just before 
1920 have old coal-fired central heating boilers which were transformed into gas or oil. These models are workhorses, but use lots of energy. A brand new furnace or boiler can help to save energy dollars immediately. Changing window air conditioning units, which we did in most these houses, having a central system may also save energy immediately, as lengthy because the tubes continues to be put into the conditioned space. Photo voltaic water heating is a great choice to add here if you're able to afford it, but at the
minimum, upgrade the efficiency of warm water production by coupling the tank towards the boiler.
3. Bring The Basement And Crawlspace Inside Your Home

Warm, dry cellars and crawlspaces can extend living and space for storage. Wet cellars 
are the source of high humidity levels and discomfort in the summertime in old houses. They can also cause mold growth that will get distributed throughout the house. Spray foam is really a fast, efficient way to create these areas in to the conditioned space while sealing the leaks between foundation and floor framework.
4. Super-insulate And Air-seal The Roofing

If air leaks in at the bottom of the home, it leaks out at the very top, making a home cold and drafty in the winter months. A poorly 
insulated roof also can produce a hot house in summer time. Air-sealing is really a by-product of excellent insulation, so it’s a real one-step process. Using spray foam within roof may also eliminate the requirement for roof ventilation, that is tricky in complicated roofs.
5. Insulate Your Walls

Filling empty wall cavities with cellulose is really a cheap, easy, efficient way to warm-up a classic house. Blowing cellulose 
into existing wall tooth decay is definitely an art, to be certain, but you will find many companies who've been doing the work for a long time. Actually, you will find now affordable methods to seek advice from infrared cameras to make certain that voids happen to be filled without disturbing the present plaster or sheathing on outdoors walls. Because siding or shingles on old houses may also normally wear out, we go ahead and take chance to set up foam sheathing around the outdoors of the home before re-siding.
6. Get Energy Star (or even better)

Fittings, home appliances, and lighting after you have reduced your parking space conditioning and water-heating loads, the 
lighting, appliance, and plug load will probably be your next large energy item. A brand new Energy Star refrigerator uses 15% less energy than the usual standard model. Changing old light fittings with pin-based compact fluorescent fittings guarantees your utility bill will remain lower (as much as 30%).
7. Put In A Renewable-Energy Supply

When your energy consumption continues to be reduced considerably, it might be reasonable to create your personal energy with 
systems such as photovoltaics, wind energy, or hydro, if you possess a stream nearby. Before you slash the energy usage, though, it isn't worth the money in renewable energy sources. Conservation remains the least expensive game around.
