A key parameter for achieving energy efficiency in buildings is the envelope design. Also, insulation plays a very important role helping reach high levels of “air tightness.” Most materials used for acoustic insulation have a very impressive thermal performance as well; insulation can refer to materials as well as to a range of designs and techniques employed to reduce unwanted heat loss or heat gain—which can decrease the energy demands of heating and cooling systems.
Often a material will be chosen for its ability to perform several of these functions at once whether it is acoustic insulation, fire insulation or impact insulation. In many cases, well-considered acoustic design can be achieved while making significant ecological performance gains and vice-versa.
A holistic approach to the components of the design process, such as site design, materials and finishing, ventilation, orientation, lighting/power and heating cooling systems is necessary to get the best results.
WSDG is working to raise its design standards in a way that will improve the energy efficiency of buildings, while creating healthy and comfortable indoor environments for its occupants. We are following acoustic materials research, tracking energy usage, toxicity levels and others parameters that occur over the entire life cycle of the products. We also continually look for high performance HVAC systems and natural lighting/ventilation strategies that do not compromise the acoustic insulation--but can significantly reduce the energy demand of the buildings.
