1 Towards Carbon Neutral Neighborhoods Planning of Dwelling Design and Energy Supply In 7 Norwegain Pilot Projects RERC 2014 Oslo, June 16th Eyvind Fredriksen Energy and Indoor Climate Architectural Engineering SINTEF Buildings and Infrastructure 1

2 Background Energy efficiency in the building sector is a national goal Norwegian authorities have introduced various incentives. TEK'10 Cities of the Future FutureBuilt program EU EPBD: all new buildings must be "nearly zero energy buildings " by Project financed by The Norwegian State Housing Bank (Husbanken) 2

3 The project Reviewed experiences of seven planned development projects in Norway Ambisious goals regarding energy use and greenhouse gas emissions Aims to increase knowledge about solutions for design and energy supply for future residential areas Guide for designing future neighborhoods Ill: Marzal et al 3

4 Levels of ambition Passive House (Low Energy) Standards Norway NS 3700 Zero Emission/Energy Building Ill: Dokka, Sartori et al

5 Case Studies 5

6 Jåtten Øst II, Stavanger Planned in 2007, not built Planned with approx. 700 residential units Thorough analysis of energy solutions, costs and greenhouse gas emissions Ill: Asplan Viak 6

7 Løvåshagen, Bergen Realized project (2008) 52 residential units in apartment buildings low-energy and passive house standard Norway's first major development project realized as passive house pilot project Formed the basis for the design of the Norwegian standard for low-energy houses and passive houses. Ill: MIR 7

8 Miljøbyen Granås, Trondheim Development area under construction of 300 housing units in single-family homes, townhouses and apartment buildings Norway's largest housing project realized with passive house standard. Available evidence from early studies of several different energy solutions. Ill: 8

9 Ådland, Bergen Development area being planned Approx. 600 units Pilot project in the Research Centre on Zero Emission Buildings (ZEB) Net ZEB ambitions Ill: Norconsult 9

10 Skarpnes, Arendal Development area under construction 37 residential units consisting of single-family homes and apartment buildings Ambition zero energy and zero emission level. Pilot project in the ZEB centre Ill: Skanska 10

11 Brøset, Trondheim Planned development area with 1,800 homes Ambitions to develop a climate neutral district Parallel assignment was performed in connection with the planning process Ill: Code 11

12 Øvre Sund, Drammen Planned development of 200 new student housing in apartment buildings Goal: 50% reduction of greenhouse gas emissions from materials and operations Pilot project in FutureBuilt Ill: Rodeo arkitekter 12

13 Summary Thermal demand: Hot water dominant Electricity % of total energy demand (hot fill can reduce this) Shape and orientation/placement of buildings Passive energy design principles Materials with low CO 2 -impact Energy supply Grid interaction Planning process 13

14 Conclusions Integrated engineering Level of ambition Availability and delivery of local renewable energy Building Design Calculations Energy Solutions 14

15 Further research This project considered: energy solutions, building design and location, building materials and construction choices Future smart communities also require sustainable infrastructure (transport, grid) This project focused on the development of new residential areas Future smart communities will also include upgrade of existing residential areas Load Matching and Grid Interaction Local grids to improve characteristics? 15
