Highest waste of energy in most building during season’s is through building’s windows, roofs and walls. The energy efficiency of building's depend upon a material that help create it’s envelope. So the building contractors paying more regards to how they can tight their envelope to bring down the energy usage and cost.
Project teams should start by considering the insulation materials they are using while making building’s envelope. Insulation reduces the heat gain as well as heat loss through surfaces of building’s like walls, roof, ducts, windows. In well insulated building’s less amount of energy is require for heating and cooling.
Energy efficient materials
●Vacuum insulation panel - 1-inch vacuum panel provides as much as six times insulating
protection as to traditional material
●Low-E Windows - “E” in low-E stands for emissivity and clear coating of metallic oxides
on these windows, keeps heat inside in winter and outside in summer.
●Plant based Polyurethane foam – When used as insulator, foam offers more moisture and
heat resistance and protection against mould and pests.
●Insulated concrete forms – “Cast-in-place” concrete walls are sandwiched between two
layers of insulating material. Concrete poured into forms that serve as insulator and remain in place as permanent part of the structure.
Other Efficient Materials
●Structural Insulated Panel
●Recycled Wood/Plastic Composite Lumber
Most practical and cost-effective way to improve building’s energy efficiency is use of insulation,
in new and old building’s. In addition, insulation can keep moisture out and improve air quality,
leading to health benefits. Global energy efficient materials market is growing due to rise in energy
utilization in building’s. Government initiatives like tax credits, rebates also encourage the usage
of these materials by builder’s. Change in consumer’s liking towards energy efficient and
eco-friendly homes will enhance the energy efficient materials demand in future. It is estimated that
Energy Efficient Materials market to grow from US$ 10.9 bn in 2017 to US$ 25.8 bn in 2026.
