Our research is divided in two areas, one for each part oft the project. The aim of both areas is to determine which factors are vital to find out which building material is the best and which facade ist he best.
In the first part we came to the conclusion, that there are several properties we need to consider to determine the optimal building material:
Ecological properties of building materials :
- Energy requirements for production, transport and disposal
- Pollutant emission during production, processing, use and disposal
- Use of recycled material
- durability, easy to repair
- Reusability
- Regionality
Furthermore we already searched for the conventional building materials that we could use to create the model. We will use the following building materials for our model:
- Natural stone
- Brick
- Concrete
- Steel
- Wood
In the second part we looked for factors to measure the impact of the different facades on the climate. We found out that the microclimate is crucial for our project. The microclimate is the climate close to the ground up to a height of 2 metres, or the climate that prevails in a small, precisely defined area. In our case we observe the microclimate of a city
Regarding the microclimate, the reflection of the facade is decisive. In the past, there has been criticism that glass facades can produce a very hot reflection of up to 100 degrees, which is extremely harmful to the microclimate. Currently, the impact of microclimate is not taken into account when distributing sustainability certificates. The reflection causes the floor to heat up critically. It also turned out that planted facade, according to our expectations, the optimal facade is, while glass will be one of the worst.
