Lighting plays an integral role in beautifying and electrifying any place. Let’s check out the steps required while choosing lighting for hotels, retail, offices and residential spaces.
The great challenge in the upcoming years is to remake our rapidly growing cities into structures that can stand up to environmental changes with residents that are healthier, happier, and more prosperous than previous generations. We often do not think about the roofs above our heads, but making thoughtful materials choices on urban rooftops is a critical, readily-implementable strategy to help meet our new urban challenges. Roofs comprise over 25 per cent of urban space and are readily accessible and easy to upgrade relative to other urban sustainability interventions. With roofing technologies that are currently available, cities can improve their biodiversity, reduce rising urban temperatures, improve health and quality of life, and defend against high energy costs and power blackouts.
Unlike ground structures, roofs are exposed to different conditions depending upon climatic zones, usage of buildings etc. Hence roof demands more robust and flexible waterproofing systems.
Providing high-performance solutions
Sika is committed to pioneering sustainable solutions to address global challenges – and to achieve this safely and with the lowest impact on resources. Sika believes in sustainable development, assuming responsibility to provide sustainable solutions in order to improve material, water and energy efficiency in construction and transportation.
We are striving to create more value for all its stakeholders with its products, systems and solutions along the whole value chain and throughout the entire life span of its products. The value created by far outweighs the impacts associated with production, distribution and use.
Energy saving solutions
Sika energy saving solution and it offers various advantages and they are as follows:
- Highly reflective thermoplastic Sarnafil roofing
- membranes and provides significant energy savings during the use phase.
- Sarnatherm insulation materials are one of the most cost-efficient solutions and have the best thermal performance for a given thickness of insulation.
- Sika thermoplastic roofing systems have the lowest energy footprint of all competitive roofing technologies compared.
- Sika roofing systems reduce the urban heat island effect and energy consumption during the use phase.
- Insulation materials have the lowest carbon footprint for a given thermal performance.
The company offers refurbishment solution with reflective SikaRoof MTC. SikaRoof MTC and Sikalastic liquid-applied membranes are an outstanding refurbishment solution that extend the lifetime of existing roofs. And by upgrading existing roofing systems, it is a cost-effective method of saving energy, minimising disruption to operations of the building installation and reducing costs, waste and carbon emissions.
Green building solutions
Sika roofing systems contribute to achieving multiple credits in most relevant green building certification programs by reducing energy consumption and the heat island effect. Using high-performance Sika thermal insulation enhances the thermal performance and buildings with Sika green roofs controlling storm water runoff. Another advantage of using Sika roofing membranes is that it includes recycled content. Sika provides externally verified Environmental Product Declaration (EPD) and Life Cycle Assessment (LCA) tools that can be used as part of the certification process. Sika also provides customised and project specific Life Cycle Assessment (LCA) calculations and reports.
Low impact solution
Innovative solvent-free Sikalastic significantly reduces odour emissions and enables a VOC-free roof buildup. This reduces the summer smog potential and improves the air quality. Highly reflective Sikalastic liquid-applied roof waterproofing membranes provide significant energy savings during the use phase. Sika offers low-VOC, low-odor and VOC-free solutions, eg. Sikalastic liquid-applied roof waterproofing membranes.
Benefits of solar reflectivity
The benefits of solar-reflective materials and colorus are well known and understood, especially in warm climates in India. With urban density increasing, the heat-island effect impacts cities at an ever increasing rate. White highly reflective thermoplastic and liquid- applied membranes (LAM) increase reflectance and reduce both the heat-island effect and the cooling energy consumption of buildings.
Sika roofing systems support to reduce heat island effect and energy consumptions by providing a very high initial Solar Reflectance Index (SRI) > 100 along fulfilling the very basic need i.e. waterproofing.
