The top energy-saving home improvements
By Laura A. Bruce • Bankrate.com

These are the top single-family home energy-efficiency improvements that reduce energy bills. The return on investment (ROI) is annual, based on 7 cents per kilowatt-hour.

Example: A homeowner spends $500 to insulate an attic that has no insulation, and saves $25 per month on energy bills. $500 divided by $25 per month equals 20 months. This means the investment paid for itself in 20 months and, for the next 30 years, gives monthly dividends of $25 per month in lower energy bills. The $25 grows each time there is a rate increase.

Humans Are Literally Space Hogs – Living little is a valuable lesson

Posted on by

When I first started talking about living in small spaces, the idea was for the space to be portable. Some houses were built on truck beds, some were built on trailers and some were easily dismantled. The idea at the time was to live where you wanted to live but not be tied down. Some of the attraction was that you could have the amenities of home without the RV costs. The craze caught on and people began to build them into a fixed space in a conventional setting. Now they have moved into the wild. Very cool idea.

‘TINY’: Give big to a short film about small houses

Now that the season of giving is officially upon us, find out how you can chip in to help make the short documentary, ‘TINY: A Story About Living Small,’ a well-polished reality.

A very happy [insert non-shopping-related descriptor here] Tuesday! Hopefully you aren’t too entirely burnt-out or broke as a result of yesterday’s responsible gift-buying bonanza because a great new Kickstarter fundraising campaign worth showing a little financial love to has recently come to my attention. And the topic of this creative project is a great one: dramatically downsized living.

Filmmaking team Merete Mueller and Christopher Smith have taken to Kickstarter to raise post-production funds for their short documentary: “TINY: A Film About Living Small.” The film (watch a teaser clip below) follows Smith as he attempts, with no previous building experience, to erect a 130-square-foot cabin in the Colorado mountains while also profiling similarly small-minded Americans. Explains Mueller on the project’s Kickstarter page: “Rather than an informational documentary about tiny houses, the film will explore the idea of ‘home’ and what makes us feel comfortable in a particular landscape or building. The film will be a meditation on the relationship of home to environment, of quality and simplicity to a life well lived.”

LLCC programs offer free training in ‘green’ industry

Posted Nov 17, 2011 @ 11:00 PM
Last update Nov 18, 2011 @ 06:45 AM

Lincoln Land Community College expects to begin training about two dozen students for “green” jobs  early next year through two pilot programs made possible by $600,000 in federal training grants.

The Renewable Energy Academy and the Green Construction Academy will provide intensive training — classes are 9 a.m. to 4 p.m. Monday through Thursday — for jobs in renewable energy and energy-efficient building.

“We are looking at a lot of new skills and jobs that have not been there in the past,” Julie Rourke, LLCC director of workforce development, said Thursday.

The renewable-energy classes are scheduled to begin Jan. 9 and the classes in green construction on Feb. 13. Both continue into mid-June.

Rourke said the school hopes to enroll 15 students in renewable energy and 12 in green construction. There will be no cost to the first group of students, because the federal grants are paying for the expense of setting up the program, including equipment.

But she said the four-days-a-week schedule will take a strong commitment.

“It’s set up that way for a reason. One is the grant period,” said Rourke. “The other is that we expect a lot of non-traditional students who may be transitioning from one career to another, and there’s an urgency to get them back in the work force.”

The grants, $350,000 from the U.S. Department of Education and $250,000 from the U.S. Department of Labor, were awarded through the LLCC HIRE Education program. The goal is to make the classes self-sustaining once the grants expire at the end of 2012.

LLCC Green Center manager Julie Bates said classes will cover a variety of renewable-energy and energy-efficiency skills, including solar, small wind systems, geothermal, green construction, plumbing and heating, landscaping and site planning.

Easy Home Winterizing Checklist

By , About.com Guide

In the fall is when you want to get ready for the winter cold. The worst thing in the world is trying to put your storm windows in when its 20 degrees outside. Or worse, not having your sprinkler system purged before the freezing weather comes.I’m going to give you a fairly easy checklist of things to do for the various systems of your home. From plumbing to roof, we’ll walk through each system and hit the major things to make sure you do before winter so you can enjoy the snow and not worry about your home.
OK, lets start with the basics of making sure you have heat when you need it. The time to check that is in the Fall, no later than the end of October. Give your system a test run through and make sure all systems are “GO“.

Heating System Checklist

  • Test Run:
    Turn the thermostat to heat mode and set it to 80 degrees just for testing. You should hear the furnace turn on and warm air should blow within a few minutes. If it’s running OK, turn the thermostat back to its normal setting. If it’s not running properly, you can try to diagnose it as outlined in Troubleshooting a Gas Furnace. Depending on what’s wrong, you can fix it yourself or you may need a qualified service technician.
  • Seasonal Maintenance:
    Either have the furnace checked by a service technician or do it yourself as outlined in Seasonal Furnace Maintenance.
  • Replace the Air Filter:
    Put in a new clean air filter. It’s easy, just follow the steps in Furnace Filter Replacement
  • Fuel:
    If you have a propane or oil furnace, make sure to have your fuel storage tank topped off and ready to go.
  • Heating Vents:
    Clear obstacles to heating vents so air can freely flow.
  • Check for Carbon Monoxide Leaks:
    This silent killer can easily be detected with either an inexpensive test badge or battery operated alarm. Whichever way you decide, just please decide to protect your family with one of these units.
    See Testing for Carbon Monoxide for more information.

Top 5 Places & Top 25 Ways to Weatherize Your Home

Excerpted from the Solar Living Sourcebook by John Schaeffer. See the book for a helpful cutaway illustration pointing out 42 places to weatherize that are discussed in this weatherization article.

Short of printing your own money, weatherization and insulation are the best bets for putting cash in your wallet — and they’re a lot safer in the long run than counterfeiting. Weatherization, the plugging and sealing of air leaks, can save you 25 to 40 percent on your heating and cooling bills.

The average unweatherized house in the United States leaks air at a rate equivalent to a four-foot-square hole in the wall. Weatherization is the first place for the average home owner to concentrate for the most benefit with the least effort and expense. You’ll save money and help the planet!

The following suggestions are adapted with permission from Homemade Money by Richard Heede and the Rocky Mountain Institute.

1. In the attic

  • Weatherstrip and insulate the attic access door.
  • Seal around the outside of the chimney with metal flashing and high-temperature sealant such as flue caulk or muffler cement.
  • Seal around plumbing vents, both in the attic floor and in the roof. Check roof flashings (where the plumbing vent pipes pass through the roof) for signs of water leakage while you’re peering at the underside of the roof.
  • Seal the top of interior walls in pre-1950s houses anywhere you can peer down into the wall cavity. Use strips of rigid insulation, and seal the edges with silicone caulk.
  • Stuff fiberglass insulation around electrical wire penetrations at the top of interior walls and where wires enter ceiling fixtures. (But not around recessed light fixtures unless the fixtures are rated IC [for insulation contact]). Fluorescent fixtures usually are safe to insulate around; they don’t produce a lot of waste heat. Incandescent fixtures should be upgraded to compact fluorescent bulbs).
  • Staple Radiant Barrier under the rafters or joists to reflect 97 percent of the radiant heat that strikes it
  • Seal all other holes between the heated space and the attic.

This is an older piece but it just shows the relevancy of this type thinking. It is short but geez the concept isn’t tough. Like the others it doesn’t talk about taking windows and rooms out of service, but then I am just old fashioned.

Dodge the draft! Weather-proof your home

by Diane Rixon, Posted Nov 29th 2007 9:00AM

Home heating costs are expected to be sky-high this winter as oil prices continue to soar. Are you ready to fight back? One thing everyone can do is weather-strip windows and doors.

First, look for drafts and determine to what extent weather-stripping is necessary. In an old house like mine, it’s pretty-much a given. In newer houses or homes that have been weather-stripped in previous years, check anyway. That’s because cracks can appear anywhere at any time.

Not sure if you’re feeling any airflow? Try holding a lit candle or match up to the spot in question. If the flame quivers, you’ll know you have work to do! One determined couple recommends the following two-pronged method: one person holds the candle up while another stands on the outside blowing air from a hair dryer in the direction of the candlelight. Not a bad suggestion, huh?

The second step is to decide how to stop those troublesome gaps. Smaller cracks can be caulked up. Other problem areas may need weather-stripping applied. Retailer Lowes has a bunch of great tips on its website. Basic pointers and pics can also be found at DIY Network. A wonderful summary of weather-stripping options can be found here, as well.

Finally, don’t forget your doors. Drafts coming in under exterior doors can be minimized by installing draft sweeps. These are lightweight aluminum strips that attach with screws to the bottom of the door, usually on the indoors side, effectively blocking the flow of cold air inwards. Use a hacksaw to cut the sweep to the correct size for your door. Remember to leave a little breathing room at each end so that the sweep does not catch on your door frame.

Weatherizing homes: The next big green industry?

by January 28, 2009 4:00 AM PST
..

It’s not the sort of thing that excites your typical Silicon Valley venture capitalist, but companies that weatherize homes could be the sleeper green-business success stories this year.

Many people would like to lower their household energy bills but need an expert to recommend what steps to take as part of a long-term plan.

There’s also a substantial amount of government support for energy-efficient retrofits, including from President Obama who has set a target of lowering utility bills at 2 million homes. The federal stimulus plan now being debated in Washington, D.C., sets aside $6 billion to weatherize low-income homes.

At the local level, too, municipal governments and nonprofits see home energy use as one the most important ways to meet greenhouse gas emission reduction goals, said Geoff Chapin, CEO of Boston-based Next Step Living, which provides energy auditing services.

“This is a tremendous time to be in the field,” he said. “Cities and towns care about creating jobs that can’t be outsourced and reducing their carbon footprint and saving people’s money, so it has a lot of support.”

Chapin founded the energy-services company last year and has weatherized more than 100 homes. A former consultant for cities and nonprofits, he founded the business in an effort to cut residential energy bills, lower greenhouse gas emissions, and create jobs.

A blower door is a removable door with fan and computer to measure air flow. There are already free home energy efficiency services. Paid services from companies like Next Step Living typically use diagnostic equipment, notably a blower door, to spot holes where heated or cooled air slips outside. (Full disclosure: I’ve signed on as a customer and am expecting my first visit soon.)

Ace Is The Hardware Place – This post is mainly about filling cracks

If you are letting cold air in then you are wasting money. Calking is the quickest way to stop that.

http://www.acehardware.com/info/index.jsp?categoryId=1282811

The average house-even when well-insulated-contains cracks and gaps between building materials that add up to a hole about 14 inches square (see image below). In the winter, those gaps may make the house drafty and chilly. All year long, a leaky house not only wastes energy but can lead to water damage and provide a path for insects.

Inside this document you will find information about:

  • Weatherproofing Basics
  • Types of Caulking
  • Using Caulking
  • Types of Weatherstripping
  • Installing Weatherstripping

WEATHERPROOFING BASICS

  • In all the discussion of insulation and R-values, don’t forget that poor weatherproofing is often a more important source of discomfort, as well as high heating and cooling bills.
  • Some air leakage can be prevented during construction by using housewrap or getting a tight fit between framing members, for example. Once the house is built, however, the remaining gaps must be sealed. Gaps around doors and window sashes should be weatherstripped, and gaps between permanent building materials sealed with caulking.

TYPES OF CAULKING

  • A number of factors must be considered when choosing caulking. They include durability, flexibility, whether the caulk can be painted and, of course, price.
  • The most expensive caulk is not always the best product for every job, so you should carefully consider which product is appropriate to your situation. Read product labels and manufacturers’ literature, and ask your salesperson for his or her recommendation.
  • Here is a list of common caulks and their characteristics. Different types of caulking are designed for different applications, and quality can vary among different brands of the same type because of different formulations used.
  • Always read and follow the manufacturer’s directions.
  • Oil-Base Painter’s Caulk (1-2 yr. life) – Not very elastic. Dries out easily. Paintable after curing. Lowest cost.
  • Latex (3-10 yr. life) – Use mostly indoors. Goes on easily. Low elasticity. Sticks to porous surfaces only. Easy water cleanup. Low in cost. Paintable.
  • Butyl Rubber (3-10 yr. life) – High elasticity. Sticks to most surfaces. High moisture resistance. Flexible when cured. Most difficult to work with as it is very sticky.
  • Acrylic Latex (10 yr. life) – Good elasticity. Sticks to most surfaces. Reasonable moisture resistance. Paintable. Good for around doors and windows. May not be used below freezing.
  • Silicon-Latex Blend (20+ yr. life) – Good elasticity. Excellent weathering ability. Medium shrinkage. Adheres to most surfaces. Some cannot be painted. May not be used below freezing.

Weather Proofing Or Weatherization – Doesn’t matter much

Posted on by

No matter what you call it, it is an attempt to keep the brrr and ssssiss factors at bay. In the Arctic and the Equator it would just be called staying alive.

http://en.wikipedia.org/wiki/Weatherization

Weatherization

Weatherization (American English) or weatherproofing (British English) is the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation, and wind, and of modifying a building to reduce energy consumption and optimize energy efficiency.

Weatherization is distinct from building insulation, although building insulation requires weatherization for proper functioning. Many types of insulation can be thought of as weatherization, because they block drafts or protect from cold winds. Whereas insulation primarily reduces conductive heat flow, weatherization primarily reduces convective heat flow.

In the United States, buildings use one third of all energy consumed and two thirds of all electricity. Due to the high energy usage, they are a major source of the pollution that causes urban air quality problems and pollutants that contribute to climate change. Building energy usage accounts for 49 percent of sulfur dioxide emissions, 25 percent of nitrous oxide emissions, and 10 percent of particulate emissions.[

Typical weatherization procedures include:

  • Sealing bypasses (cracks, gaps, holes), especially around doors, windows, pipes and wiring that penetrate the ceiling and floor, and other areas with high potential for heat loss, using caulk, foam sealant, weather-stripping, window film, door sweeps, electrical receptacle gaskets, and so on to reduce infiltration.
  • Sealing recessed lighting fixtures(‘can lights’ or ‘high-hats’), which leak large amounts of air into unconditioned attic space.
  • Sealing air ducts, which can account for 20% of heat loss, using fiber-reinforced mastic(not duck/duct tape, which is not suitable for this purpose)
  • Installing/replacing dampers in exhaust ducts, to prevent outside air from entering the house when the exhaust fan or clothes dryer is not in use.
  • Protecting pipes from corrosion and freezing.
  • Installing footing drains, foundation waterproofing membranes, interior perimeter drains, sump pump, gutters, downspout extensions, downward-sloping grading, French drains, swales, and other techniques to protect a building from both surface water and ground water.
  • Providing proper ventilation to unconditioned spaces to protect a building from the effects of condensation. See Ventilation issues in houses
  • Installing roofing, building wrap, siding, flashing, skylights or solar tubes and making sure they are in good condition on an existing building.
  • Installing insulation in walls, floors, and ceilings, around ducts and pipes, around water heaters, and near the foundation and sill.
  • Installing storm doors and storm windows.
  • Replacing old drafty doors with tightly sealing, foam-core doors.
  • Replacing older windows with low-energy, double-glazed windows.

The phrase “whole-house weatherization” extends the traditional definition of weatherization to include installation of modern, energy-saving heating and cooling equipment, or repair of old, inefficient equipment (furnaces, boilers, water heaters, programmable thermostats, air conditioners, and so on). The “Whole-House” approach also looks at how the house performs as a system
