Green doors and windows
Environmental design and sustainability in construction business is, like other technical questions, a highly sophisticated issue that demands a more complex approach, both from the supply and demand side of the market. Correct implementation of basic sustainability and efficiency principles drives down cost, increases efficiency, improves the bottom line and, most importantly, reduces the burden on the environment in which we all live.
Environmental design and efficiency at construction projects places a particular emphasis on the façade, window and door segments of the industry to achieve the bulk of energy, material and cost savings in the overall design of a building. This is recognized by the leading manufacturers of this sector, everyone of whom is actively designing and promoting products based on the basic principles of environmental design and sustainability.
However, having individual companies coming up with various products and promoting them individually is not enough. For optimum allocation of resources, it has been suggested that there must be a centralized forum where supply and demand can come together and determine the true market and take advantage of opportunities for environmental design and efficiency products in today’s construction industry.
LEED (Leadership in Energy and Environmental Design) Green Building Rating System provides a complete framework for assessing building performance and meeting sustainability goals. Based on well-founded scientific standards, LEED emphasizes state-of-the-art strategies for sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.
Here are recommendations on what to look for in environment-friendly doors and windows.
Green window and door guide
1. Manufacturer’s commitment to environmental stewardship. 2. Energy efficiency. The building envelope is a key part of how a building will perform in relation to energy efficiency. When a building has windows and doors, there are holes in that envelope that could compromise the energy efficiency. That is why window and door choices are critical and only high quality and energy-efficient windows and doors should be used. 3. Wooden windows with triple glazing and blinds between the glass are one option because they offer excellent U-values and thermal properties of the wood. 4. Recycled content. Evaluate the amount of recycled content used; this
can be post-consumer or post-industrial. 5. Indoor air quality. The main issue with indoor air quality is VOC (Volatile
Organic Compounds); at the very least products need to meet some type of requirements, such as Green Seal. 6. Day lighting and views. These are a key window property for green, because windows allow in natural day lighting which reduces or eliminates the need for artificial lighting and creates savings on energy costs. A key component is to place windows and shading devices at a location that maximizes day lighting and minimizes heat gain. Views are maximized if all occupants have visibility to the outdoors. Studies show this contributes positively to both the work environment and life improvement. 7. Increased ventilation effectiveness. Operable windows can assist with this if the building is going to be naturally ventilated in order to reduce the need for mechanical systems for fresh air flow. 8. Light pollution. Lights can pollute the night sky and neighbouring properties, including the interior lights from a building. The goal is to eliminate light trespass from the building. 9. Wood as a building material utilizes renewable resources. 10. Certified wood. There are several wood certification systems available, the most well-known being FSC (Forest Stewardship Council) and SFI (Sustainable Forestry Initiative). Most of the well-known certification systems are developed and used with the same key purpose in mind, which is to practice sustainable forestry.
