Green Construction Materials

Thursday, April 19th, 2012

Many people are now opting for using green construction materials when building a home in order to lessen the impact on the environment. These materials can either be used partly in the construction of a home alongside other, more standard building components or green construction materials can be used entirely to build low impact homes.

A low impact home must make use of natural construction materials that are native to the area in which the home is being built. In doing this, less energy is wasted transporting materials long distances and less energy has to be used converting such materials into usable construction tools for a home.

Low Impact Housing vs. Standard Homes

The principles of building low impact housing involve using as little energy as possible, using green construction materials that use little energy to resource and the use of materials that conserve heat and enhance the natural environment. These principles can be taken to extremes when building new homes or they can be used in moderation to build standard homes that are more eco friendly.

Factors to take into consideration when building an environmentally friendly home include how to provide higher levels of insulation to the home in order to conserve heat and reduce the need for heating within the home, in which direction to build the home in order to make the most of natural light from the sun and including green construction materials such as energy efficient lighting and other electrical appliances.

Low impact homes may be built with triple glazed windows, high levels of insulation such as cavity wall or loft insulation and may include features such as solar panels mounted on the roof. Some low-impact homes have been built with no heating system in place and thus must be built with every care and attention to conserve heat within the home.

Mostly, using green materials during contraction and building low impact homes is far cheaper than building standard homes where little consideration is given to the environment. It is also important to think about the position of the home in relation to public transport routes or the distance away from work or the centre of town and local amenities.

Considerations when Choosing Materials

When choosing which materials to invest in when building low impact housing it is necessary to consider the cost, both in money and energy, of extraction of any material and how long such a material will last. Green construction materials are chosen for their long-life span such as hard woods. It is also important to avoid using materials that are non-renewable.

It is imperative to use materials for use within construction that are easily recyclable and that have been sourced locally as far as possible when building a home. This reduces energy consumption when delivering materials.

There are many examples of homes that have been built entirely using green construction materials. These include homes that have been made solely from wood and straw, mud and constructions made from recycled tyres that have been filled and packed together with mud or clay.

Colorado Home and Garden Show is a Hit in 2011!

Monday, February 14th, 2011

With all this snow piled up it was great to see such a big crowd at the opening day of the Colorado Home and Garden show. 14 gardens filled with plants and bright flowers sure made me feel spring were just around the corner. And for kids and big kids like me the life like dinosaurs makes one wonder how they do that.  My Seminar on The basics of Green Building and Remodeling went well and most of the questions afterwards were about energy efficiency and how they could make their home more comfortable and save on heating and utility costs.  Today at the show at 2:00 PM I will be presenting a topic called Home Accessibility for Today and Tomorrow. This is not a easy or simple subject to discuss because most of us do not want to think we will not be able to manage stairs  and many other little things around the  home that we have taken for granted for so many years. For more information visit  www.gardeningcolorado.com/garden/colorado-garden-home-show

The Colorado Fall Home Show is Friday-Sunday September 10-12.

Friday, September 10th, 2010

The Colorado Fall Home Show is Friday-Sunday September 10-12.  On each of those days I will be presenting a seminar, “The Basics of Green Remodeling and Building.”   I really enjoy doing these presentations; sharing my experiences and meeting people who have an interest in energy efficiency and other Green Building ideas.  My presentation times are Friday, Noon, Saturday, 11:00 AM, Sunday, 2:00 PM.  For more information visit www.gardeningcolorado.com.

Green Building is picking more and more acceptance in both residential and commercial and energy efficiency is the basic element and that is the foundation on which and building or remodeling project should be based.  See you at the show.

Bad Beetle has destroyed millions of trees on our Colorado forest land

Thursday, September 9th, 2010

As many of you know the last few years the “Bad Beetle” has destroyed millions of trees on our Colorado forest land. No one has ever counted the tree loss really but it is immense.  This caused me to dig back into my memory bank when this happened to some of our forests back in the 80”s .  At that time the word “Green” in our industry did not even exist and there was very little discussion about environmental issues as compared to today.  But, back in the 80’s our company saw the beauty in the beetle kill pine and we used it for cabinets, built-ins, and interior trim.  A leader in beetle kill pine flooring today is T&G Flooring right here in Denver. So if you want the whole story with the facts visit www.tandgflooring.com and then talk to Chris Keale, the owner. And you can also visit him or one of his staff at the Colorado Home Show in booth 515 this weekend. Find out how this flooring is part of Green Building. Just tell them the Beetle sent you.

Green Building: What it is and why it matters.

Thursday, July 1st, 2010

 Green building, sustainability and high-performance homes are now part of the vocabulary of new home construction. We welcome the attention brought to these important issues. As professional builders, however, we take the subject with a grain of salt. Green building is a far more complex topic than that portrayed in the media. News spots or magazine articles typically focus on specific areas like insulated windows, high-efficiency furnaces, roof-mounted solar panels, or recycled-content flooring. Certainly, those products provide measurable benefits in terms of energy savings and improved use of natural resources, but genuine green building is much more complex. A green builder uses a systematic approach to design, construction, and on-going operational durability in which the sum of the benefits are far greater than the individual components. A green builder also knows how to personalize the green building approach to each homebuyer’s needs and budget, carefully balancing the value that the client places on the benefits of green building as opposed to other choices available for new home construction. It is true that all homes (and all buildings) leave an environmental “footprint.” The materials we builders use in new construction use natural resources, such as trees and metal ores, even oil. The important goals of green building are to reduce the amount of natural resources required to build a house, and then to lessen the amount of energy used by the house. Energy efficiency over the life of the house further reduces the natural resources needed to produce electricity oil, and natural gas. To achieve those goals, we look for building materials, products, and systems that make the most (or best) use of every resource harvested while also performing better than traditional products. For example, an engineered beam uses smaller, fast-growing trees. Twice as much of each log can be used to make an engineered beam as compared with a comparably sized wooden beam. An engineered beam can also span longer, open spaces and resist warp better. A house that is free of even the smallest gaps does not waste energy. Various green building certification programs are now available to help builders create more sustainable and resource-efficient homes. As we review them, however, we often find that the building practices we already have in place meet or exceed those standards. That’s good news for our homebuyers and owners because it means we’re already providing a high-performance home — i.e., a home with many green features — without adding to the cost or price. Of course, a client may choose to add additional features as budget, needs, and passion for the environment dictate. It is my belief that it is necessary to have a green home certified by a third party program before it can be truly labeled a green home. With a systematic approach to green or sustainable building, we can build a new home that not only leaves as small an environmental footprint as possible, but also delivers durability, comfort, safety, energy and water efficiency and a higher level of value.

What Build it Green Really Means

Friday, May 7th, 2010

It is very common to see something about Green in our newspapers and magazines.  Include television and the internet and it is a fair thing to say the we are at times in Green Overload.  Yet, I believe there are many who do not have a clear understanding of what Green really means. Since this blog is going to be mainly about Green, Energy, Environmental, Building topics and other matters connected and even occasionally disconnected from those topics, lets start off with a reasonable definition of Green as it relates to the building industry. ‘Green Building is the process of design and construction techniques based upon energy efficiency, water efficiency, durability, indoor air quality and comfort and the use of products that have a positive impact on the environment.’  I wrote this definition for the Built Green Program of Colorado in 1995. 

So regardless of the Building type whether it is residential, commercial, industrial, educational etc, that definition will be acceptable to most of us. It provides all builders with a solid foundation and easy for most anyone to understand. I believe that the cornerstone of Green Building is energy efficiency. That is the basis of all Green Buildings in all climate zones.  Obviously different climate zones have different heating, cooling, power and lighting needs.

It is simpler for us to understand and appreciate the benefits of energy efficient homes.  Lower utility bills, less of an impact on the environment and better indoor comfort. 

Here is a link to a Green Building Program that will provide more good information on this topic.
