Thanks to the World Wide Web and more accessible and affordable travel, the world is the smallest it has ever been. People are able to get to the other side of the world in less than 24 hours, for fewer dollars than ever. As a result, a new trend is developing. While it has always been commonplace in the US, more and more countries are adopting the idea of the staycation and holidaying domestically.

Both the US and the UK have seen a rise in the number of staycations being taken in 2014, with 10% more Americans vacationing within the United States, and reports from a Suffolk cottages agency in the UK expressing record bookings this summer, staycations are at an all-time high.

In theory, vacationing in the homeland is a great deal more environmentally friendly than flying to an overseas destination. This is because air fares have such a large impact on carbon emissions. Choosing to use public transport or drive your own car is a great deal more green than purchasing a plane ticket.RV at Redrock Canyon State Park - Davido~O

However, in vast countries like the United States, staycations have the potential to not be so green. With such long distances to travel, flying is often the only option and of course with flying involves huge carbon emissions. 

A return trip from Los Angeles to Orlando for a family of four generates a massive 6.5 tonnes of carbon. During the average lifetime of a single tree, it will absorb just one tonne of carbon meaning that seven trees will need to be planted to offset your vacation.

Surprisingly, cruise ships are also a very environmentally harmful way to holiday, they emit three times more carbon than aircraft. Approximately 14 ounces of CO2 is emitted per passenger, every 1000 yards travelled.

So what ways can you take to decrease your overall carbon footprint on vacation? Here are just a few ways you can have an eco-friendly vacation without leaving the country:

 Rent an RV with a friend or with your family to minimise costs and your carbon footprint all at once. 1 in every 12 vehicle owning households in the US owns an RV, so it seems logical to utilise these vehicles and take a trip to a state or city you have never visited before. Over the course of the year an RV will emit

Even taking careful consideration when choosing the hotel you stay in on your vacation can help to minimise your carbon footprint. Many hotels have “gone green” and now make small efforts to limit their negative impact on the environment. Efforts include only washing the bed sheets at the end of the visitor’s stay or switching to water efficient showerheads. Hundreds of thousands of hotels are joining The Green Hotels Association, like a Chicago Hyatt, which reduced their waste hauling by 80% since being part of the association.

Walking and biking holidays are becoming increasingly popular in the US, with 34.54 million people going hiking or backpacking in the Fall 2012 and Spring 2013 period. Vacations such as these are beneficial for your health, and as almost as environmentally friendly as you can possible be. In addition to this, there seems to be a positive pattern of camping in the States, 42.5 million Americans (14.9% of the population over the age of 6) went camping in 2011.

It seems that the recession has led to fewer Americans seeking to vacate abroad, and instead preferring the comfort of our own back-yards. This of course is favourable to the welfare of the environment. So whether you’re staying in a beach hut by the sea, or a reliable hotel, camping or even a mobile home why not try your own version of a staycation this summer? You might find that it is less hassle and more enjoyable than venturing abroad.

half timber houseBuilding Biology advises us to look for a successful history of use when choosing building materials but in our ever changing product-based building environment we seldom have the luxury of evaluating track record. This becomes quickly apparent when vetting new products for client’s homes. I recently called a major manufacturer to find out what was in a new product developed to prevent mold growth on framing lumber. I wanted to avoid the use of biocides for this chemically sensitive client. The rep said with great pride that the product had now been out for six months and that they hadn’t received even one warranty complaint!  When Building Biology addresses the principle of history-of-use it is looking at a bigger picture…not six months but decades and centuries! 

In the brief history of building with petrochemical-based products, centrally produced by a handful of very powerful corporations, we must often put our trust in new products expecting them to do what the manufacturers have claimed they will do. Time-accelerated lab testing can help us to project how a material may behave over time but it is not an exact science and nothing can surpass the real test of time.

New “smarter” products for building our homes are being invented all the time and while advertising campaigns continually grind out tantalizing lists of benefits for the latest and greatest, the manufacturers are silent about the millions of homes that were built on yesterday’s promises…those products that failed to become the “super endurables” they were initially advertised to be: waterproofing materials that have been conveniently re-named “water resistant”, construction tapes that lose their “stick” over time,  foams that get tunneled by insects, insulations that shrink away, products that leach chemicals, and so-called harmless chemicals that are found to be harmful.

In contrast the pre-industrialized buildings that populate the old world, intact and serving for centuries, are the bi-product of thousands of years of building evolution that preceded them. They represent holistic systems that were perfected for their local climate, from their local resources and by their local craftsmen. They are made of natural non-proprietary materials and they have successfully weathered the test of time. They embody the principles of sustainability by their very nature. This valuable heritage of accumulated wisdom is little understood or acknowledged in current North American building and it has become the precious baby that got thrown out in the bathwaters of industrialized building assembly.

Many of us who have embraced natural building have found that, contrary to what manufacturing interests would have us believe, we can not only use time-tested materials and traditional craftsmanship to build our homes, we can create enduring spaces that nurture us, nurture the environment and serve our modern lifestyles well. All of the buildings throughout Europe and Asia that are several centuries old stand as a testament to longevity and they have several things in common:
They are built of the natural materials at hand
They have massive wall construction
They allow for the free flow of vapor through them…no vapor barriers.
They have the capacity to handle large fluctuations in moisture without deterioration
They are petrochemical free and biodegradable.

We can build building with such longevity in North America too. Why don’t we? As long as we continue to see housing as a short-term financial investment for personal gain rather than a contribution to the wealth of future generations, initial cost per square foot will continue to be the most important perception of housing value. It remains the rare home-owner/investor who is willing and able to step outside the conventional housing industry, pay more for something that will last beyond their lifetime and reap the benefits of living in a naturally healthy home along the way

compost tea 1

When I was first attempting to build a garden at my Ecohut, even though I grew up on a farm, I had no idea how to build soil. I was privileged to grow up on a working farm before chemicals became the norm. We didn't have an organic garden, we had a garden.  

I watched endless videos on YouTube and read many books. Lasagna Gardening by Patricia Lanza is a great book and always Ruth Stout, but there was never a conclusive DO THIS! bit of information in any of the books I read. Yes, composting is vital, but the gardeners on YouTube who were growing amazing gardens were using this home creation called Compost Tea.  

I watched many videos on YouTube about compost tea, but every video had some 'secret' ingredient they were trying to sell, so after watching many videos I started to experiment with materials I had on hand. The secret I came to find out was a magical tea 'activator' for $49.95

A Recipe for Compost Tea

I have found there is no exact recipe for compost tea. My compost tea recipe is based upon materials readily available, so here is a basic recipe for compost tea, and short of killing your batch with sulphured molasses, there is no wrong answer for my witches brew.   

Water: I use rainwater when available or my awesome well water.  

Oxygen: I started with a small aquarium pump in a 5 gallon bucket. Now I make 40 gallons  at a time and use a large air pump that I bought. An air compressor will do.

Unsulphured Molasses: I use approximately 1/4 cup per 5 gallons. Make sure to use UNsulphured molasses only. The sulphur will kill all the microbes in the tea.

molasses

Manure: Cow, sheep, horse, rabbit, bat guano, whatever you have available.

Hay: Alfalfa, alfalfa or alfalfa is the best. Spoiled or new alfalfa both work great.

That is my basic recipe. Oxygenate the water, add dry ingredients plus molasses. Continue to inject air into your tea for the duration of brewing.

Microbial life grows and feeds on oxygen and carbohydrates (molasses) and will be evident by a frothy head on the batch.  When either of these is eliminated, the tea will go anaerobic very soon. Apply to your garden asap.

Compost tea can be added directly to the soil around your plants, or strained for use as a foliar spray.

I have made many recipes of compost tea, and no two batches are ever the same in terms of the microbial growth which is demonstrated by the frothing action of the tea.  So don't be discouraged, keep brewing.

According to statistics, Americans are responsible for roughly 25 percent of global emissions of carbon dioxide, which is more than any other nation and on a per capita basis is 6.6 tons of CO2 annually. In the U.S., most carbon dioxide (98 percent) is emitted as the result of burning of fossil fuels.

Surprisingly residences account for as much as 21 percent of U.S. CO2 emissions with 68 per cent of residential emissions coming from the consumption of electricity and 80 per cent of those coming from the burning of coal at coal-fired power plants, which residences use for lighting, air conditioning, heating and other household appliances.

In order to help reduce energy consumption and CO2 emissions, and to achieve the rule put in place to reduce America’s carbon dioxide emissions by 30% from 2005 levels, housing in the US needs to be made more energy efficient through improved insulation.

Although efforts have already been put in place to help reduce CO2 emissions from residences, for example, the Leadership in Energy and Environmental Design (LEED) is helping buildings save energy, water, resources and money, efforts need to increased considerably further in order to reduce residences carbon emissions by a significant amount.

Much of the existing housing stock in the US is not insulated to the levels it should be today, with older homes in particular, significantly using more energy than they should, which is not only bad for the environment but also leading to higher heating and air-conditioning bills. Newer homes tend to be much more energy efficient because they have been built with ‘being green’ in mind.  However, while some newer housing is being built in the US, a large percentage of US housing is old.

The UK is an example of a country who have put in place a system, called the Green Deal, to help improve energy efficiency in housing and reduce the UK’s carbon emissions from residency. The Green Deal is a new way to pay for energy-saving home improvements. Brits are able to take out Green Deal finance to pay for measures such as loft, cavity or solid wall insulation, glazing, a new boiler or solar panels. Which makes us question, would the U.S. benefit from a similar system? As a lot of U.S. residents may be put off investing in insulation for their home simply because of the costs that are associated with it.

Not only are is the UK government introducing new green government initiatives, they are also cracking down on building new homes that are extremely energy efficient. For example, just one example of a new housing development in the UK are the new homes in Norfolk by Abel Homes. Each home has been fitted with triple glazed windows, ‘Superwall’ insulation, insulated ground floors and lofts, low energy lighting and have Solar PV (meaning that homeowners will enjoy free electricity that it generates as well as benefit from the ‘Feed in Tariff’ payments from the Government for 20 years).

Although newer green housing is being built in the U.S., because of the size of the country, it is not having such a significant effect on reducing the carbon emissions that the U.S. are generating.  And if the U.S. want to reduce the carbon footprint from U.S. housing, government efforts need to be significantly improved.

Two friends from our last natural building workshop called, "The One-Day Cob House," put together this wonderful ten-minute video of the event. The good folks at House Alive! partnered with us at Be the Change Project for a memorable weekend that resulted in a great cabin and lots of great connections. 

I hope you enjoy watching it!

The most recent figures reveal that the U.S. releases the most CO2 emissions in the world after China. Texas is the most polluting state, with 2011 figures stating that their annual CO2 emissions total a significant 656 million metric tons, despite California having a larger population than Texas.

The U.S. has already increased efforts to improve their carbon footprint and to become a more environmentally friendly country, with figures revealing that the nation’s carbon dioxide emissions from energy fell 12 percent between 2005 and 2012. However, 2013 figures showed that U.S. carbon-dioxide emissions from energy sources increased back up by 2 percent. Although this means that energy related carbon emissions are still 10 per cent below 2005 levels, which is a significant improvement, efforts need to be increased further in order to make the nation more green. President Obama has already set a goal of achieving 17 per cent below 2005 levels by 2020.

In order to reach this goal, more needs to be done to improve the efficiency of U.S. homes. A 2011 study revealed that the average U.S household’s carbon footprint was as much as 48 tons per year with 13 tons being from housing. According to Flir, heat loss can account for up to 50% of total energy consumption in a building with causes ranging from air leakage through chimneys, attics, windows and through lack of insulation.

Using a Thermal Imaging Camera

A thermal imaging camera can be used to detect just how much energy is lost from a home, highlighting the most problematic areas where energy is being lost. For example, there is a new program that has started in Connecticut in which a car with a thermal imaging camera goes around towns and captures pictures of individual homes to see how efficient they are. The program is helping residents to become more energy efficient as when homeowners log in to the company website, they are able to see a thermal imaging photograph of their home. There is no obligation for them to do anything but there is an option for home owners to choose to get a home energy assessment for less than $100.

Not only is the energy that is being lost through housing harmful to our environment, but also to household’s wallets. Many U.S. citizens are overspending on energy bills because they are either losing heat or struggling to keep their home cool because their homes are so poorly insulated. Many people are put off insulating their home, because they associate these solutions with high costs. However, what people need to realise is that in the long term, insulating a home will save homeowners a significant amount of money and is a worthwhile investment. Below are just a few long term solutions to insulate a home that homeowners should consider in order to save money and reduce their carbon footprint.

Wall Insulation

According to figures, roughly 33 percent of energy and heat is lost through walls. Therefore, getting cavity wall insulation is one of the most cost effective energy saving measures that homeowners can carry out. This is supported by research that has found that every square meter of cavity wall insulation will save more than a tonne of CO2 over the average lifetime of a building.

Loft and Roof Insulation

It is also very important to insulate the roof and loft of a home as up to quarter of a home’s heat can be lost through the roof. Loft and roof insulation is certainly a worthwhile investment because it is low cost and can last up to 40 years and will repeatedly pay for itself during that time.

Triple Glazing

Double or triple glazing is a great way to trap any energy in and reduce the amount being lost into the atmosphere. Although double or triple glazing can be a little more pricey solution (especially triple glazing which is up to 30-40% more expensive than double glazing), when compared with loft insulation for example, many consider it to be worth the extra expense. Not only will it reduce the amount of air leaking out of the home, but will also will increase security levels of a home and the amount of outside noise.

Underfloor Heating

Underfloor heating has become an increasingly popular choice to improve efficiency of homes. Roughly 8 per cent of heat is lost through floors. Underfloor heating is essentially like having a giant radiator under the floor, creating extreme levels of comfort whilst at the same time significantly contributes to reducing household’s carbon footprint. Obviously investing in an underfloor heating system will depend on where about homeowners live in the U.S. – but for those that live in colder states, it is certainly an investment worth considering. RA Brown a company that specializes in underfloor heating and Ground Source Heat Pumps in Suffolk explains how an underfloor system is eco-friendly – it can depend on natural energy sources and doesn’t emit any harmful gases. And whilst the initial cost of installation may be a high, the running costs are very low.

If more U.S. citizens implemented some of these long-term solutions to improve the efficiency of their homes, we could see a dramatic reduction in the amount of CO2 emissions released by the nation. And for those where the initial costs of installing some of these long term insulation solutions may be too high, in the long term it is worth the investment and will save homeowners money over time. Plus there are funding schemes available to help homeowners pay for insulation solutions.
