Materials and components

• Self compacting concrete SCC

• Ready built Penthouses

• Masonry- versus timber houses

Building the future

Self-compacting concrete

Features:increased productivity, reduced environmental impacts (no vibration and noise), improved concrete quality (no vibration to damage the air void structure) and fewer defects in casting difficult details and dense reinforcement.

But requires:Better control of the materials, better casting logistics, better control of pressure on formwork and on incomplete compacting

Building the future

A future building combining the human needs for good indoor comfort, low energy consumption and use of renewable energy

The prototype was manufactured in an industrial process and transported to the site for mounting

SOLTAG – A prototype of a CO2 neutral apartment

Building the future

The prototype combine the basic human needs for fresh air, daylight and good comfort with the general need for low energy consumption

Building the future

In Copenhagen there are among 100.000 m2 with flat roof, that can be used for roof apartments.

The area is assumed to be much bigger in the central and eastern Europe.

Building the future

Masonry vs. timber

Competition through

1. Indoor climate2. Price and time3. ”the feeling” (heavy vs. Light)4. Durability and maintenance
