This striking building is the first structure to be completed in a new office and commercial district on Landsberger Strasse in Munich. Six storeys of office space with a façade featuring large fibre cement and aluminium cladding elements rise up from a transparent base. The aluminium cladding on the continuous bands of windows is responsible for the building’s characteristic silver shimmer. LAIM 290 has been awarded a silver DGNB certificate for its outstanding level of energy efficiency.

Measures to reduce CO₂ emissions

• Climate control with concrete core temperature control and water/water heat pump to supplement district heating
• Controlled ventilation with heat recovery and windows that open
• Use of geothermal power from groundwater well for cooling
• Water-saving technology in sanitary facilities
• Green roof to retain water
• Environmentally friendly mobility due to optimal integration into the regional network of cycle paths and excellent public transport links

Eco-balance
The annual primary energy requirement for LAIM 290 is 9.35 kWh/m², which is significantly below the maximum permitted value of 15.74 kWh/m².

Exemplary façade insulation
The back-ventilated curtain façade with its fibre cement and aluminium panels helps create the optimum indoor climate. The space for back ventilation between the components regulates the moisture balance within the building by reliably dissipating moisture from the structure and interior. Mineral insulation of all thicknesses can be used, thus ensuring compliance with the requirements of the German regulations on energy saving in buildings (EnEV).

Concrete core temperature control and controlled ventilation with heat recovery
To supplement district heating, concrete core temperature control is deployed at LAIM 290. A high proportion of alternative energy is used in the form of geothermal power via a water/water heat pump. If tenants wish, an additional recirculation system or radiant ceiling panels can be installed for cooling.
Another environmentally friendly, energy-saving element is controlled ventilation with heat recovery plus natural window ventilation. This enables ventilation-related energy requirements to be reduced by approximately 70%.

Geothermal cooling
LAIM 290 uses geothermal power from groundwater for space cooling. Energy from the earth is transported into the pipes of the concrete core temperature control system from a 140-metre deep well. Filter lines in the soil and a closed water loop keep the groundwater clean and safe. In conjunction with effective energy and heat recovery, operating costs can be reduced long-term in an environmentally friendly way.

Water-saving sanitary fittings
The toilets have dual economy flush buttons. Urinals are fitted with electronic water-saving flush controls.

Attractive green offices with roof landscaping
Workers at LAIM 290 enjoy the comfort of a green office. All-round windows allow abundant daylight to penetrate into the rooms, while users themselves have control over room temperatures. The external solar shading consists of motorised aluminium fixed louvers. Windows can be opened on every second axis and are sound-insulating. The temperature can be regulated further thanks to additional panel radiators.
The green appeal of these offices is enhanced by roof landscaping on the first floor – an interesting design feature that also provides space to relax and unwind.

Floor plans designed for future flexibility
This building is ideal for the modern working world: highly efficient layout planning sees each storey of 1,300 square metres divided into a maximum of three rental units. Open plan space arrangements are grouped around the central access cores, giving users excellent views and flexibility when it comes to fit-out.

Green mobility and urban integration
Environmentally friendly access was an important planning objective. The central location guarantees optimal integration into the regional network of cycle paths and excellent public transport links.
With its mix of retail stores and food outlets on the ground floor and nearby residential and green space, LAIM 290 also offers a high quality user experience and fits well into the existing urban infrastructure.
