fit4power2heat

The integration of heat pumps can increase the cost effectiveness of existing heating networks and counter the high costs for the expansion of power grids at the same time. Aim of the project is to develop innovative business models for small and medium municipal heating networks with focus on synergies between heat and power market. Main focus is a heat pump pooling for several heat grids.

PHOTOVOLTAIC WATER Solution

Passive House refurbishment facade with integrated photovoltaic modules for direct, current-based warm water preheating. The GIWOG, an energy-conscious and environmentally and socially oriented client, intends to undertake an energy-related modernisation project, which will further optimise energy consumption to be more efficient at an apartment complex in Graz, main street 302-306. The goal is to lower the energy consumption for heating and hot water from the current level of approximately 135 kWh /m²a to approximately 8 kWh /m²a. The planned measures should correspond with an overall energy consumption reduction of approx. 94 %.

KoPro Lzk+ - Cost and process optimization in the life cycle of nearly zero energy buildings

The aim of the project was to develop a continuous process chain for the energetic-economic optimization of zero and plus energy buildings. The project focused on proven and new approaches to cost reduction of nearly zero energy buildings (nZEBs) at all stages of the life cycle. The main goal was to identify the extra-costs for nZEBs, and to promote innovative approaches taking into account the cost-effectiveness for all the Stakeholders. A database containing important cost parameters and potential savings will be developed.
