Energy-plus housing estate
Utilising decentralised electricity in the district

The energy-plus “Ludmilla-Wohnpark Landshut” housing estate was built on an industrial brownfield site. Close monitoring and the subsequent optimisation of the building operation significantly reduced the energy consumption.

A blueprint for energy-efficient housing renovation
Residential Complex Aims for Net-Zero Energy Supply

Built in 1955 in the Au-Haidhausen district of Munich, a residential complex comprising four 3- or 5-storey buildings with basements and an unconverted attic was in need of refurbishment. The 149 existing apartments with either two, three, or four rooms ranged between 40 m² and 65 m² in size.

Energy balancing of buildings
EnerCalC – Simplified Energy Balances Based on DIN V 18599

The energy balancing of buildings in accordance with DIN V 18599 has been frequently criticized because of its complexity and resulting time-consuming application. The Excel-based EnerCalC tool, which was developed in 2011 as a learning tool.

Financing model for new-build scheme
Public-private partnership finances new energy-efficient administrative building

A special financing model was used for delivering the project: a public private partnership or PPP for short. Despite a tight public budget, the client (the Region of Hanover) has succeeded in constructing a consistently energy-optimised building for 300 staff.
