20 Resources Water - Waste Storm Water Management / TEC 1.3 Water Cycle Systems / ENV 2.6 Efficient Waste Management / TEC DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
21 Water and Waste Content: What are resources? Concepts from the water cycle rain water management waste Basics Solutions for storm water management Basics Approaches to water systems Basics Waste management solutions Legal principles, regulations and standards Other Criteria 21 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
22 Drinking Water Drinking water is a common good and should be made available to the consumer via a central supply Each region needs to be treated in order to eliminate pollutants from the environment, industry and agriculture An efficient use of this valuable resource is imperative 22 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
23 Waste Water Waste water is any water that has already been used In residential buildings, it can be separated into gray water and waste water containing fecal matter Usually both types are treated together in a sewage treatment plant before it can be reintroduced into the natural water cycle Currently, valuable ingredients (such as phosphates and nitrogen) are not recycled 23 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
24 Rain Water Rain water is a natural precipitation which is not contamined by use It can be collected from the roof of buildings and used as process water for purposes that do not require drinking water quality (e.g. washing machines, toilets, garden irrigation) The unused rainwater should be allowed to remain in situ upon the land as long as possible (ponds, gutters, greenroofs) or to allow for evaporation over time. Feeding this water into the sewage system will likely overburden the piping and unnecessarily increase the need for sewage treatment plant 24 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
25 Process Water This water is not drinking quality, but is instead used in an operational process, such as garden irrigation or in washing machines Well water and recycled grey water is also classified as process water 25 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
26 Grey Water Grey water is treated, recycled water from showers, baths, washing machines It is used for watering gardens and flushing toilets They can also be used for heat recovery 26 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
27 Rain Water Management Current status? Sealed Area: Prevents the natural water cycle Leads to flooding events Requires oversized sewage system 27 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
28 Rain Water Management Current status? Combined Sewer Waste water and storm water to be disposed of in a pipe/duct system Seperate Sewer Waste water and storm water are Seperated into different channels 28 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
29 TEC1.3 Rain water management Targets: Promoting concepts that provide decentralised rain water management in order to prevent flooding and to improve the local climate Development of measures developed which correspond as closely as possible to the natural, site-specific water balance of rain water volume, evaporation and surface drainage and associated ground water recharge Minimising the negative impact of developed and sealed surfaces on the natural water cycle 29 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
30 Close-to-nature Rain Water Management Infiltration Trenches Benefits No sewer needed for rain water No maintenance costs Aesthetically appealing Children s play area Greenbelt for animals 30 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
31 Close-to-nature Rain Water Management Green Roofs Benefits 70 % rain retention Good form of insulation Visually appealing Durable High ecological value (honey bees) Good in urban areas Reduces carbon footprint 31 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
32 Close-to-nature Rain Water Management Percolation Systems Benefits Space-saving, underground passable Large retention area Good groundwater recharge Drawbacks High investment costs Water needs prior to discharge into cleaned groundwater 32 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
33 Rain Water Management Percolation Systems Graf 33 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
34 Close-to-nature Rain Water Management Watering with rain water Benefits Very natural as evaporation is encouraged Many profiteers: plants, soil, climate, social environment Rain water is collected and used Drawbacks High investment of large rain storage and irrigation 34 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
35 Water Circulation Systems - Supply Methods of saving gray water Voraussetzung Separate Management System Drinking water and process water pipes must be seperated with a free outlet to DIN 1989 Seperate Sewage System Waste water containing excrement needs to be separated from gray water 35 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
36 Circulation Systems Retention Reduction of run-off Retention Volume Retention volume of underground storage Water circulation systems Deprivation and prepartion Retention Volume Effective Volume Ideal: Combination of rain water harvesting and rain water retention 36 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
37 Benefits of Rain Water Harvesting Optimum utilization of the accumulated rainwater Flood prevention through buffering (use house and garden) Savings of up to 50% water Overflow can not simply walk into a pond or drainage system Garden irrigation: better water for the plants Laundry: soft water increases the life of the machine, use less detergent Toilet flushing: No food into wastewater Cleaning: No calcification 37 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz

49 Pre and Post Consumer Waste Most applicable for Industrial Districts 49 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
50 Waste Waste of today is the resource of tomorrow Waste awareness is an active component of climate- and resource conservation For Industrial Districts the following topics should be adressed: Waste prevention Waste reduction Reuse Recycling Energy and optimal storage 50 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
51 Florentine, pixelio.de ErikaErika Hartmann, pixelio.de TEC1.2 Efficient waste management Targets: Separate waste management balance sheets and concepts Models of municipal or districtrelated waste streams Implementation of measures to optimise the waste management material flows in cities and districts can reveal the potential for sustainable waste management. 51 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
52 TEC1.2 Efficient waste management Indicators: TEC1.2.1 Waste prevention and waste reduction TEC1.2.2 Re-use TEC1.2.3 Waste recycling TEC1.2.4 Energy recovery from waste TEC1.2.5 Technology and logistics TEC1.2.6 Secure storage of waste 52 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
53 TEC1.2 Efficient waste management TEC1.2.1 Waste prevention and waste reduction Method: Evaluation of the promotion of target group oriented information and education campaigns as well as events for all user groups in the district (residents, industrial and commercial users) Evaluation of measures waste reduction for the other logistics (for example using waste compactors or similar measures in the district) 53 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
54 TEC1.2 Efficient waste management TEC1.2.2 Re-use Method: Following aspects are evaluated by means of a checklist: 1. Establishment of composting facilities for compostable waste that arises in the district and / or 2. Provision of compost to residents of the city district 3. Establishment of re-use and repair services and / or 4. Establishment of collection points, where old, but still re-usable items can be donated and purchased and / or 5. Establishment of websites for the city district where used items can be sold/exchanged/donated 54 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
55 TEC1.2 Efficient waste management TEC1.2.3 Waste recycling Method: Evaluation whether there is a waste recycling system which ensures the collection and separation of the district waste specified below. This can be done at a public collection point or within private households, provided it is mandatory and enforced. The separation of materials need not necessarily be done in the district as long as there is proof of the further recycling loop 55 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
56 TEC1.2 Efficient waste management TEC1.2.4 Energy recovery from waste Method: Evaluation of the establishment of collection points for waste and rubbish which is intended for use to generate energy for the district. (For example, a collection point for the biogenic share of household waste for the capture of biogas for subsequent conversion to heat and electricity in a thermal power station). 56 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
57 TEC1.2 Efficient waste management TEC1.2.5 Technology and logistics Method: Evaluation of innovative waste logistics concepts in the district (e.g. a waste centre, which is supplied with pipeline systems, conveyor belts and electric collection vehicles) Evaluation of innovative waste-management technology (e.g. rubbish compactors to extract water from the waste, or waste pits which lead into underground reservoirs to avoid noise and visual impact, etc.) 57 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
58 TEC1.2 Efficient waste management TEC1.2.6 Secure storage of waste Method: Evaluation of the establishment of collection points for waste, including hazardous materials, which is regularly removed and disposed of in an appropriate and environmentally-friendly manner 58 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
59 Summary Conclusion: The goal is to choose systems that recreate a natural, hydrological balance This distributed approach can lead to financial savings from reduced investment and maintenance costs The building owner has the opportunity to install a rainwater harvesting system at a low cost There is good protection again heavy rain events This protection is intensified if combined with rainwater harvesting 59 DGNB GmbH / Happold Consulting 2014 Thomas Kraubitz
