Buildings are the largest source of energy consumption and greenhouse gas emissions in the U.S. and worldwide, and as a result, roof systems can play a major role in energy efficiency and environmental responsiveness. There are many sustainable roofing options available, including vegetative roof systems, cool roofs and photovoltaic technology for roof systems. Before determining optimal roof system design, materials and installation methods, each roofing project requires considering many factors, including building use, climate, location, budgets, financial incentives, life-cycle costs, performance standards and maintenance issues. Lan-Way Roofing Co., Inc can assist with options relating to energy efficient roof systems.
While there are numerous “Green” ways your roof can assist with reducing energy and environmental concerns, a simple, low-cost approach like switching to a “cool roof” or white roof membrane, is an easy place to start. Begin with the type of membrane recommended to conserve energy and assist with environmental concerns. Reflective Membranes such as TPO, PVC, white coatings, and white granulated modified bitumen, ease cooling needs while reducing energy costs. These types of membranes also play a tremendous role is reducing carbon emissions.
Solar roof panels are a particular type of solar panel meant to be placed on the roof of a building for the purpose of collecting photovoltaic energy to convert to electricity, or as a method for heating water. Solar panels work by harnessing the energy of the sun, converting it into energy that can be stored and used by humans. The type of solar panel known as a solar thermal collector works by absorbing the energy into a liquid medium, such as water, to later use as heat energy. The type of solar panel known as a photovoltaic module converts this energy into electricity, which can then be stored in battery bays to be used at a later date.
Vegetated roofs, or green roofs, have a layer of living plants on top of the structure and the waterproofing elements. Green Roofs help to reduce roof storm water runoff and in some cases can help reduce the size of storm water pipes and the amount of storm water that needs to be treated by municipal water treatment. Green roofs also protect the roof membrane from sunlight, which breaks down the roofing material. Even a couple inches of soil helps to greatly extend the life of the roof. Green roofs keep the roof cooler, which helps to reduce the heat-island effect, which contributes to cities being hotter than the surrounding countryside. This can be beneficial to the building in reducing its summertime cooling load.
