Hemp 101 for Construction a Sustainable Finishing Material HELLO Hemp 101 for Construction A Sustainable Finishing Material HELLO, Welcome to Hemp 101 for Construction: An introduction to one of the oldest and "newest" building materials on earth. For professionals in construction who are new to hemp... This is not a technical guide, it's an overview of a high performance, versatile, and resilient natural material that's going to flood the market in the coming years. We'll take a short look back at hemp's history, dive into technical and functional uses, then look forward to how it can help us collectively move towards a more sustainable earth. Through the lens of your professions, you can view this material from many perspectives, recognize its limitations and potential, as well as evaluate both short term benefits and long term returns. I created this guide because the reemergence of hemp is recent, and so naturally, many people have never heard of the plant, or think hemp is Marijuana. Education on the facts and science is our path to breaking the stigma, and to adding one of the strongest fibers on earth to our toolbox. I invite you to explore it, and consider it on your next project. Hebah Saddique, PMP Founder, Green Takeover October 2020 1 GREEN TAKEOVER Born to bridge the worlds of climate action and industrial hemp, Green Takeover symbolizes the union of these two movements. Our mission is to inspire action using hemp as a catalyst for a green economy. Hemp fits directly into conversations of a circular economy, regenerative design thinking and materials for a closed loop. It fits into the blueprints of green cities. It fits, accelerates, and enhances solutions addressing 1/3 of the United Nations Sustainable Development Goals that relate to a green economy. Green Takeover is a hemp-focused sustainability, project, and management consultancy. Helping clients strengthen their connection between strategy and operations, partnering with them to implement bold radical initiatives, and working with them to adopt best-in-class sustainability strategies. We're personally invested in a booming hemp industry. Growing hemp plays a vital role in cleaning our soil, absorbing enormous amounts of carbon from our atmosphere, reducing our footprint, and enhancing our collective climate action efforts. Hemp is good for people, profits, and our planet. We encourage you to explore it, grow it, and use it, because in the end, we're all in this together.

It's a resilient and breathable, low on toxins, long lasting and recyclable material that combines a variety of properties making it appealing to build with. Hemp Insulation A durable, low-carbon, sustainable insulator. It'll keep buildings warm in the winter and cool in the summer due its high thermal mass and low conductivity. Available in insulation blankets or boards, and can be used for insulating roofing, floors, and even drywall. Natural Insulations Hempcrete Used to build non-weight bearing infill walls. Architects love hempcrete for its design flexibility and performance benefits. Builders for low maintenance requirements. Hempcrete is not a structural element so it's not a direct substitute for concrete. Left Hand Hemp Hemp is an environmentally superior material because it is a carbon sink. It's take in 2 times as much Carbon as mature trees in a comparable area. Plus, it takes very little energy to grow and process into insulation. It’s recyclable at the end of its useful life and can be repurposed and made into paper products or a biofuel. October 2020 9 HEMP INSULATION Hemp is a prime insulation material that can help building owners save money on energy, and provide a healthier space. It's a low carbon & durable alternative to fiberglass. Its low thermal conductivity ( 0.039 W/m°K) allows it to not only retain heat but also regulate thermal performance for an optimum indoor environment. Due to the high silica content of hemp it makes for very energy-efficient buildings because it has the ability to store warmth and give it back after a while.

  • Natural Materials These Are Materials That Are ‘Naturally’ Found Around Us
    Natural Materials These are materials that are ‘naturally’ found around us. We may have to dig them out of the ground, grow them, or take them from living things. Wood It is used for burning, building houses, benches, fences and lots of other things. It isn’t chemically processed so it is natural. Wood comes from stems and roots of trees and other woody plants. Cotton Cotton is a soft, fluffy material that grows around the seed of the cotton plant. There are no chemical processes used to make cotton so it is a natural material. The cotton is spun into yarn to make a soft breathable fabric. Cotton is used to make clothes and furnishings. Gold Gold is a metal found as nuggets in rocks. It is not chemically processed so it is a natural material. Gold is melted down to make jewellery, gold teeth and used in industry. Gold is also used for investment. It is kept in bars which are worth lots of money. Iron Iron is a metal. There is lots and lots of iron on earth. It is found in the earth’s crust and core. It is not chemically processed therefore it is a natural material. It is used to make gates, buildings, tools, fireplaces, piping and many more. Leather Leather is a material created by the tanning of animal hide and skins. Usually from cattle. It is not chemically processed therefore it is a natural material. It is used for shoes, jackets, other clothing, upholstery and also used in industry. Sand Sand is made from ground up rock and mineral particles.

Among them, sustainable acoustic materials have helped to improve acoustical comfort in built environments, and their use is rapidly growing in the architecture, automotive, aerospace and construction industries. These materials are manufactured through a responsible interaction with the environment in order to avoid a depletion or degradation of the natural resources, and to allow for long-term environmental quality. This Special Issue reports on some research studies on membrane absorbers and fibrous materials of natural origin that can be sustainable alternatives to traditional acoustic materials. Keywords: sustainable materials; sound-absorption; natural fibers; acoustic materials; recycled and recyclable materials; membrane absorbers; nanofibers 1. Introduction Although the term is complex, and several definitions of ‘sustainability’ can be found in the literature, the report presented by the World Commission on Environment and Development to the United Nations General Assembly in 1987 stated that the use of resources and the development of technologies should “meet the needs of the present without compromising the ability of future generations to meet their own needs” [1].

    Minerals In Your Home Activity Book Minerals in Your Home Activity Book Written by Ann-Thérèse Brace, Sheila Stenzel, and Andreea Suceveanu Illustrated by Heather Brown Minerals in Your Home is produced by MineralsEd. © 2017 MineralsEd (Mineral Resources Education Program of BC) 900-808 West Hastings St., Vancouver, BC V6C 2X4 Canada Tel. (604) 682-5477 | Fax (604) 681-5305 | Website: www.MineralsEd.ca Introduction As you look around your home, it is important to think of the many things that you have and what are they made from. It’s simple - everything is made from Earth’s natural resources: rocks, soil, plants, animals, and water. They can be used in their natural state, or processed, refined and manufactured by people into other useable things. The resources that grow and can be replaced when they die or are harvested, like plants and animals, are called renewable resources. Those that cannot be regrown and replaced, like rocks, soil and water, are called non-renewable resources. All natural resources are valuable and we must use them conservatively. Mineral resources are natural Earth materials that must be mined from the ground. We use them every day, and they are non- renewable. Some are changed very little before they are used, like the rock granite for example, that is commonly used to make kitchen countertops or tombstones. Other mineral resources, like those that contain useful metals, must be processed to extract the metal ingredient. The metal is then manufactured into different parts of a product, like a toaster or a smartphone. Whether you are practicing violin in your room, eating a meal in the kitchen, watching TV in the living room or brushing your teeth in the bathroom, your daily activities use things that come from mineral resources.

  • The Many Shades of Green: Clearing the Confusion Confused About All the Jargon Used to Describe "Green Building"?
    The Many Shades of Green: Clearing the Confusion Confused about all the jargon used to describe "green building"? Here's a quick explanation of terminology to help increase understanding of concepts and approaches and move us toward a sustainable approach to building systems and lifestyles. Sustainable Building and Lifestyle. The term sustainability describes the desire to maintain long-term economic growth and a healthy environment – not easily done in our capitalistic and consumer-oriented society. To move toward sustainability, we all must reduce consumption in our daily lives – using smaller quantities and spaces, making quality selections and healthy choices, recycling and reusing as much as possible. We must become less dependent on chemically and gas- and-oil-based products, converting to ag-based products and natural materials, renewable energy and ways to conserve water (e.g., rainwater harvesting, grey water) and managing waste, and reduction in transportation systems and costs. Natural Building. Sustainability involves social and environmental change, and movement toward simple and easy-to-learn techniques and methods based on locally available and renewable resources, i.e., any method of harvesting or using a resource (earth, clay, straw or another fibrous material or crop residue), so that the resource is not depleted or permanently damaged, and using the approach of appropriate technologies. Appropriate Technologies. To be appropriate, technology must be connected to the place, resources, economics, culture and impacts of its use. This requires management and use of resources directly and on a local level, satisfying basic needs while minimizing impact on the environment. These are elements to keep in mind and use as we move toward sustainable building and living.

  • Hemp Enterprises in the Czech Republic
    Masaryk University Faculty of Social Studies Department of Environmental Studies Diploma Work Šárka Roušavá, B.A.A. Towards Environmental Sustainability: Hemp Enterprises in the Czech Republic Study Advisor: Benjamin Vail, Ph.D. Brno 2011 Thanks I would like to express my gratitude to Benjamin Vail, Věra Horáková, Michal Ruman, Jiří Vyhlídal, Nadia Johanisová, Dairel Pérez Santana, Helena Švédová, Vít Šindlář, Kateřina Sedláčková for all their inspiration, feedback and technical help. Thanks also to all the respondents for participating and to Hana Gabrielová for providing hemp paper, which this diploma work has been printed on. Declaration I declare that I worked on this diploma work independently and with the use of the listed literature. Brno, 20 May 2011 Šárka Roušavá, B.A.A. 2 Annotation A partial solution to some of the wide-ranging environmental problems of our time could be provided through the cultivation of hemp, one of the most resilient and diverse plants, and its implementation in the economy. Cannabis sativa is environmentally beneficial in its actual cultivation, contributing to soil health and climate change mitigation. Furthermore, hemp can be made into thousands of useful, non-toxic and easily recyclable or biodegradable products in the food, pharmaceutical, textile, paper, building, energy and other industries thereby offering environmentally-friendly alternatives to polluting materials and processes that are currently being used by petroleum- and synthetics-based economies. In addition to a description of the plant and some of its many uses, aspects of its historical and global context are described. On the premise that hemp use can have a positive impact on environmental sustainability, the main objective is to explore the state of hemp culture in the Czech Republic – to discover who have been some of the players in the Czech hemp industry, to determine what obstacles they face and what factors have made it possible for some of them to flourish.

  • Use of Renewable Energy Sources in Construction of Green Building
    3 VIII August 2015 www.ijraset.com Volume 3 Issue VII, July 2015 IC Value: 13.98 ISSN: 2321-9653 International Journal for Research in Applied Science & Engineering Technology (IJRASET) Use of Renewable Energy Sources in Construction of Green Building Guduru Venkata1, Suresh Bhargav2, Sumit Choudhary3, B.S.S.P.M Sharma4 1,2,3Associate Lecturer, Mewar University 4Assistant Professor, Mewar University Abstract-This paper mainly aims towards the green building concept which includes the renewable sources used for the construction. The green building concept is very much useful in keeping the environment clean which on a certain view even increases the life period of construction. Building materials typically considered to be 'green' include renewable plant materials like straw and mud brick, timber from forests certified to be sustainably managed, recycled materials and other products that are non-toxic, reusable and renewable. The increasing population in a certain way has decreased available free land for new constructions. The choice of products used to build, renovate and operate structures has a significant impact on the environment. When specifying any materials, it is important to consider their life cycle environmental impacts. Wood products have less embodied energy, are responsible for lower air and water pollution, and have a lighter carbon footprint than other commonly used building materials. The paper mainly aims towards the few questions which are very much important in developing the infrastructure of the country. The materials mainly used for constructing a green building. The efficiency of the buildings which are made of renewable constructing sources. The cost effectiveness of the buildings.
