Discover how attractive your business can be by saving energy
At COP21 world leaders created the Paris Agreement, setting clear timelines to curb greenhouse emissions from every major sector of the global economy, including buildings & construction. Taking action on buildings remains among the most cost-effective means of reducing global emissions. International experts, including World GBC have calculated that to stay below 2 degrees of global temperature rise, and ideally a maximum of 1.5 degrees.
The result is that clients and architects are under increasing pressure to push the boundaries of creativity and innovation and design great buildings that meet both current and potential regulations cost effectively.
Although sustainability is still used as a loose term, there are rigid and complex certification schemes and regulations in place to deliver energy efficient buildings, such as the Building Research Establishment Environmental Assessment Method (BREEAM) and Leadership in Energy and Environmental Design (LEED) along with various national and regional standards. These are multifaceted and require an in-depth knowledge to meet the rigorous standards in order to make an energy efficient building.
One key way to reach this goal is to reduce the energy consumption of buildings, which account for 40% of energy use in the developed world. Heating and cooling are responsible for two thirds of this; due in large part to poorly insulated building envelopes, including roofs, walls, floors and foundations, as well as a lack of air tightness.
There can be different strategy for energy- efficient building where ROCKWOOL Stonewool Insulation can make a mark.
The aim of energy-efficient design is to create a comfortable and healthy indoor climate that consumes a minimum amount of energy. An optimal blend of spatial design, construction and installation technique is required to achieve this and is more relevant as there are various certification schemes and directive requirements are enforced in various parts of the world.
One of the strategies can be “Three-step or Trias Energetica” strategy.
Trias Energetica is a simple and logical approach to energy design that helps to achieve energy savings, reduce our dependence on fossil fuels and save the environment.
The three steps of this strategy, to be followed in the order below, are:
- Avoid unnecessary use of energy through measures such as insulation, compact buildings, airtight construction, ‘natural’ ventilation, heat recovery, natural cooling and water saving.
- Use renewable energy sources such as wind, solar power and water.
- Use fossil fuel energy as efficiently as possible by utilising HR-heating; optimal pump and DC powered an arrangement and reusing waste heat.
There can be other basic strategies like below.
- The durability of components within energy saving measures (lifespan)
- An integrated approach to building design (integral).
- Financial options (economic).
To help our customers meet this challenge, ROCKWOOL Group, the world’s leading supplier of sustainable stone wool insulation, provide tools and services to unlock the energy saving potential of your entire building design, reaching far beyond insulation.
We are a supplier of solutions that do contribute to energy efficient buildings. The effectiveness of these depends on the other measures in the design of a building. We recognise that our solutions will not make an energy efficient building on their own but we are here to ensure that our solutions work coherently to provide sustainable buildings of the future.
