Energy

Integrated planing

A deep concern in all our project work is to reduce the CO2 burden on our environment and the energy costs. Dynamic simulation models enable us to optimise future energy consumption even before the plans are drawn.

The use of daylight control reducesthe consumption of electricity for lighting, and at the same time increases the quality of the comfort in our buildings.

And not least the environment is protected by our Green Building Concepts and the useof renewable energies.

We do this with:

Green Building Integrated Planning – Integrated Energy Design (IED)

A team of architects and engineers from Germany together with local Croatian Partners develop individual solutions from the very first draft to the optimization of the building, even in operation.

LOHAS

- A 245 € billion market segment in the United States (growth app. 10%a/y) - A 375 € billion market worldwide

(estimated to represent approximately 40% of the population in a very few years to come).

LOHAS are consumers and a target group passionated about:

The planet, environment, social issues, health, about human rights, relationships, fair trade, sustainable practices, peace, spiritual and personal development.

They tend to make their purchasing decisions in keeping with their values of social and environmental responsibility. They can afford „living“ what they believe in as they are mostly well educated and have a reasonable income. Part of their conviction and life (style) is:

Sustainable Living & Working with Environmental Commitment!

“What is good for me is also good for the environment“

Mrs. LOHAS

• Lives in a well-insulated multiple dwelling • Car-sharing• Cycling favoured over car driving for short trips • Uses green electricity • Purchases organic food• Purchases energy-efficient appliances („A++ devices”) • Supports environmental associations

Sustainability starts more than 300 years ago in German forestry

The forest is therefore deap implemented in the Germans heart.

This tree belongs to the old German Tradition. At the same time it is the origin and meaning of “Sustainability”.

That´s why the tree is Germany´s symbol of Sustainability

One of the biggest “Carbon Eater“ in the World !
