Norway – energy context for housing construction Environmental Policy in the building sector in Norway Some projects Observations and reflections Business case Agenda

Environmental Policy in the building sector in Norway TEK (Technical Regulations) Goal: - to reduce energy consumption in buildings /cost efficiency - to raise the quality of living standards Focus areas: 1.Land usage 2.Energy usage in buildings (building net energy, production and heat recovery) 3.Materials without toxins and waste 4.Adaptation to climate

Public transportation is the backbone in the urban structure. The outer hubs are made for park&ride. A strong center – high concentration of jobs, housing, trade and cultural features. Concentrated development – commercial and residential areas with good public transportation. Local communities – dense and diverse residential buildings, green spaces, schools, kindergartens, trade and industry. Interconnected green areas of different quality Bicycle network – quick and effective communication Main road system bypasses local communities. Commercial buildings with strong car dependence located by main road system. Future cities

FutureBuilt Goal: - Realize the 50 model projects with at least 50 percent reduced greenhouse gas emissions - Be showcasing national and international projects - Encourage innovation and change in building practice. Environmental Policy in the building sector in Norway

Privat house - Talgje 2013: prototype of prefabricated massive wood construction Goal general: sustainable and local materials (Wood from Valdres), short construction time (5 days), materials without toxins (wood fiber insulation, elements with mechanical joints) Ratio Arkitekter AS, Norsk Massivtre AS

Student houses - Trondheim : prototype of prefabricated massive wood construction Goal general: sustainable and local materials, short construction time, materials without toxins, space-efficiency MDH Arkitekter SA | Arne Henriksen Arkitekter AS

Appartements - Oslo 2014: urban transformation Goal general: social meeting rom, sharing, daylight, space-efficiency, sustainability Aspelin Ramm

Community houses - Hurdal 2013: aktivhus Goal general: self-reliance, community, low-tech solutions, 0-energy houses, materials without toxins Aktivhus/ Gaia

Private house - Larvik 2014: ZEB pilot project Goal general: daylight, view and contact with landscape. Passive heating and cooling, materials have been chosen based on thermal characteristics and embodied energy, but also on the basis of their ability to contribute to a good indoor climate, air quality, and aesthetic qualities.

Agenda Norway – energy context for housing construction Environmental Policy in the building sector in Norway Some projects Observations and reflections

Investigated: - Indoor climate (comfort) - Energy consumption - Construction process - Costs Area of investigation: -77 residential buildings Method: -Survey -Measurement Lavenergiprogrammet: 10- year program between public and private market with a goal to raise knowledge and educate on energy efficiency and renewable energy sources. Observations and reflections - does it work

Energy consumption -Lower energy use -Compensate for bad habits -User behavior one of the key-factors -Better knowledge when adjusting future legislations (standard values) Indoor climate -Good comfort qualities and possibilities for individual adjustment Costs: -2% - 20% more Observations and reflections - does it work

It gives more….. -Energy certificates – better sale-value -Quality – better quality (comfort and flexibility) -Lower energy bills and better predictability -Good investment for the future (risk management, green bonds) -Green buildings as a part of educational process WGBC: report on green buildings as a business case Observations and reflections - good business MVRDV and Space Group

Observations and reflections- new challenges – resilient cities of tomorrow MVRDV and Space Group Technology - Users
