There are ways to make your existing building 'green' without making major structural changes. One can take steps to reduce environmental impact by effectively managing the way a building uses water and energy. The mantra is - 'start with small changes, which can add up to a big impact'. Here are few steps one can take to make an existing building go green:
First thing you can do is to change existing light bulbs with compact fluorescent bulbs, which use up to 75 percent less power. It is also green idea to put lights on a timer so they automatically shut off at night or when you are away. Make sure all building's lighting uses energy efficiently. You should also ensure that your heating and cooling systems are maintained regularly so they use energy efficiently and last longer.
Ensure your building is well insulated. This would prevent wastage of energy on heating or cooling. Similarly, there are numerous ways, which we all know, to reduce our building's electricity use. Put them to practice.
Do not waste water. By fixing tiny issues one can not only preserve water but also save money. Use dual-flush toilets. Fix leaks and replace your existing fixtures with low-flow options. According to the New York State Department of Environmental Conservation, low-flow shower heads save over 7 gallons per minute!
