LogPark Hamburg is pioneering the sustainable construction of logistics properties. The office space is heated using a geothermal system, while the warehouses use gas-fired radiant tube heaters. Tenants save up to 75% on their heating bills for the office space, with cooling in summer another advantage. Use of renewable energies, a high proportion of daylight and maximum thermal insulation reduce energy consumption in the warehouses by more than 30% compared to conventional logistics facilities. The DGNB certificate in Gold was awarded at EXPO REAL 2010 for long-term sustainability and user-friendliness.

Measures to reduce CO₂ emissions

• Façade with exceptional heat insulation
• Use of renewable energy (geothermal power)
• Heating and cooling with brine/water heat pump
• Heating with individual room control
• High daylight factor through large number of skylights
• Daylight-linked lighting, also manually adjustable
• Water-saving technology
• Use of timber with PEFC certification and 80% low-emission building materials
• Sophisticated recycling and deconstruction concept
• Redevelopment of brownfield site: use of a former industrial and military site
• Excellent public transport links
  
  

Façade: abundant light, low heat transmission
Featuring 14 cm of mineral wool and complying with the 2009 German Energy Saving Regulations (EnEV), the façade and roof insulation meets high standards of thermal insulation and moisture-proofing for the building envelope. Heat loss through transmission is limited in efficient fashion, while the large number of skylights provides good natural lighting.

Geothermal power for heating and cooling
Groundwater is used to cool and heat the offices at LogPark Hamburg. The required energy is generated via a geothermal system using a brine/water heat pump. The groundwater is passed through a heat exchanger and pumped back into the subsurface. In summer, this is sufficient to maintain the temperature of the cooling water circuit, while in winter an additional heat pump heats water for the heating system. This eco-friendly approach slashes energy costs by up to 75%. The heating can be individually controlled on a per-room basis.

Daylight-linked lighting
The lighting in the warehouses is daylight-linked. Power consumption is reduced dramatically through the large skylight area and the above-average use of natural light. Users can also switch individual lighting zones on or off manually, especially in low-traffic areas. Additionally, electronic ballasts (EB) are fitted to the lights.

Water-saving sanitary fittings
Low flush WCs and water-saving fixtures such as photoelectric sensors on the taps reduce water consumption significantly in the toilets. The assessment of specific water consumption conducted for DGNB certification indicates that it is more than 50% below the threshold.

Construction materials that promote healthy air
Great importance was attached to low-emission and ecologically high-quality materials. 80% of the materials are certified low-emission materials. 100% of the timber used originates from PEFC-certified sources.

Deconstruction and recycling concept for maximum flexibility
Easy deconstruction and a high proportion of recyclable elements were a documented feature of the deconstruction and recycling concept, with the checklists for layer structures providing further evidence of strong credentials in this area. Each system detail is reversible, i.e. it can be removed during deconstruction, making it possible to extend the building as required. Most of the concrete, steel and light-metal components, the glazing and electrical fittings can be deconstructed and recycled.

Offices with the feel-good factor
The thermal comfort of the workplace was certified according to the DIN EN ISO 7730 standard and ASR (German workplace regulations), as well as VBG (German occupational health and safety regulations). Acoustic ceilings were installed in some areas to further improve sound insulation. A healthy interior environment is also supported by the exclusive use of materials that present no risk to health.

Space-saving attention to detail
Optimisation of the supporting structure and in particular the positioning of the supporting pillars allows the maximum number of storage locations, i.e. pallets, racks, etc. The office units are positioned along the front of the warehouse building. This means they are well lit but do not intrude into the warehouse area. In line with tenant usage needs, only relatively small warehouse offices and break rooms were integrated into the warehouse itself. This arrangement allows efficient workflows while still making the best possible use of space.

Compensatory measures conserve the environment
Permission to build LogPark Hamburg was linked to compensatory measures. Accordingly, significant investment was made in ecological conversion of a military site.
