E3 Model: trade-off analysis Euros, Energy & Emissions
You want to make your building more sustainable, but where do you start. What choices do you make? How do you weigh the energy savings against the environmental burden of the material involved in the solution? We help you make the right choice, data-driven. We do this by providing insight into the financial impact, energy savings and environmental burden of the measures. For example, we can map the environmental burden of the measures in a sustainability plan/roadmap and offer support in design and material choices in a renovation or new construction project.
Making the right
With the E3 model, we use a life cycle approach that includes the financial impact, energy savings and environmental impact of sustainable measures. We bring these aspects together in a life cycle analysis (LCA) for the environmental impact and life cycle cost (LCC) for the financial impact. With the combination of LCA and LCC, you can see at a glance which sustainable measures are the most attractive.
For the LCA, we analyze:
- Avoided CO2-emissions due to energy reduction.
- Environmental burden of materials used.
- Material burden of maintenance and replacement.
- Circularity of materials used.
For the LCC, we analyze:
- Initial investment.
- Cost savings due to energy reduction.
- Cost of maintenance and replacement.
- Residual value.
Figure: The E3 model makes choices easy: facade insulation in this case has both the most avoided emissions and the lowest (even negative) life cycle cost. Over its lifetime, therefore, it makes a profit. Then the choice goes between Floor insulation and PV panels: one scores better on climate, the other on cost, but both are more attractive than LED lighting.
How do I design a new building to be as sustainable as possible? Using variant studies, we help provide insight into the CO2 and financial impact of design choices. In doing so, we include the materialization of the entire building and look at the entire life cycle.
Making your building more sustainable can be done in many ways, but sometimes you have to make choices within the available budget. Do we put PV panels on the roof or do we insulate? And which insulating materials have the lowest environmental impact. We make the choice easy by looking at the entire life cycle from both a climate and financial perspective. Here we can examine different scenarios: What achieves the greatest impact? What is possible within the available budget? Which measures are the most cost-effective?
There are numerous routes to a sustainable building. That is why it is important to calculate the measures in terms of the intended energy savings as well as the environmental impact of the materials. Suppose you want to insulate the facade: what material should be used? How does the Rd value of the insulation material compare to the CO2 footprint of the material? Things like environmental burden, lifespan, maintenance and residual value all affect the effectiveness of the measure. With the E3 model, we put different options side by side to make a data-driven choice.
