Environmentally friendly construction, or green building, is a concept that involves building structures in a way that minimizes their harmful impact on the environment. The most important elements of green building are maximizing energy efficiency, reducing water usage, using less building materials, and reducing or eliminating waste. The benefits of eco-friendly building include higher market values, reduced energy costs and operating costs, and lower pollution levels. Green building standards are managed by the United States Green Building Council, through its Leadership in Energy and Environmental Design (LEED) rating systems. LEED ratings range from “Certified” for basic compliance, to Silver, Gold, and finally Platinum for buildings whose eco-friendliness are exceptional in magnitude.
- Buildings can save up to a tenth of their energy costs with the installation and proper use of programmable thermostats to regulate the building’s internal climate.
- Allowing in sunlight during the winter months can reduce heating and lighting costs, while using window blinds with lighter colors during the summer, can reduce air conditioning costs.
- Proper maintenance and cleaning of ducts can save up to a quarter of energy costs, especially in a home.
- Installing Energy Star-rated windows can reduce energy usage by up to ten percent.
- Insulate pipes, electrical outlets, electrical switches, and water heaters.
- Set lights to turn off in areas where there is no activity. Set office equipment and computers to go into sleep mode when they are not being used, and be sure to turn everything off when the office closes. This can cut a building’s electricity costs by up to 40 percent.
- Install energy-efficient light bulbs to further reduce a building’s energy costs.
- Diffusing skylights can maximize the benefits of skylights in the winter, while minimizing the problems with skylight heating during the summer.
- Solar energy panels generate energy from the sun without using fossil fuels, and when placed on roofs they can reduce a building’s dependency upon utility grid power.
- Check for leaks on a regular basis, and fix any leaks immediately.
- Use drip-irrigation instead of traditional water sprinklers. Programmable sprinkler systems are another option. Moisture sensors can detect the level of moisture in the soil and determine whether irrigation is necessary.
- Rooftops designed to catch storm water can provide water for irrigation, among other benefits.
- Instead of water hosing sidewalks, sweep them clean with a broom.
- Watering should be done in the early hours of the day or after the sun has gone down, when there is less of a chance of evaporation.
- Use plants that are native to the area when planning landscaping projects, particularly plants that are adapted to local weather conditions, to reduce the need for watering.
- Replace toxic cleaning products with environmentally friendly versions, to reduce the risk of water pollution.
- If possible, consider using gray water, or non-potable water, in urinals and toilets.
Replace old toilets with water-efficient, low-flush toilets. Replace old sink faucets with sensors to detect when someone is using them. Alternately, replace old sink faucets with faucets that use spring loaded valves.
- Use thermoplastic polyolefin (TPO) roofing materials to reduce the amount of heat that roofs can absorb from sunlight. Light colored materials can also work. These materials help reduce the problem of urban heat islands, which can heat up the entire neighborhood.
- Use materials obtained locally to reduce the greenhouse gases used to transport materials.
- Cellulose insulation, which comes from recycled newspapers, makes good insulation for buildings and homes.
- A variety of eco-friendly materials can be used in the making of triple-paned windows. These include wide insulated glass, sustainable foam, argon or other inert gases, and a fiberglass frame. These windows can reduce a building’s heating and cooling costs.
- Reuse and recycle packing materials rather than throwing them away.
- Avoid packaging that is designed only for one use. Purchase items in bulk to reduce their per-unit cost and how much packaging is used overall.
- Prefabricated building materials can reduce the amount of material used during construction, as well as the amount of material that is wasted.
- Avoid using plastic utensils in cafeterias.
- Reusing wood, glass, concrete, metal, and other construction materials, prevents such materials from going into landfills.
- When recycling is impractical, it is also possible to prevent landfill usage by selling the remaining building materials that might otherwise go to waste, or donating the material to receive tax breaks.
- Switching to a paperless office can save a business thousands of pounds of paper per year.
- Pallets and corrugated paper boxes can be reused, and broken ones can be repaired and reused.
- Replace bathroom paper towels with air-dry units.
