3. Sustainable construction

New construction will be at a zero-energy level, and the carbon footprint of housing will be small.

Description

Renovating the existing building stock will play an important role in improving the energy efficiency of housing and services. Service properties are al-ready being renovated and improved so that building elements are preserved and reused as much as possible. Things that are no longer in use are sold and recycled wherever possible. These measures also contribute to the circular economy.

Low-carbon construction is directed through competitive tendering processes of consultants and contractors, as well as framework contracts for master and architectural design. The calculation oft he carbon footprint is included in the target price calculation at the stages of needs assessment and project planning. Choosing low-carbon building materials reduces the carbon footprint of construction in both building construction and infrastructure construction.

CO2 emissions from infrastructure construction are reduced through landmass management, such as recycling them and utilising them on the original site. This will also save natural resources and achieve cost savings through reduced transport operations. Additionally, the reuse of soil generated in construction will be increased, as landfills are slowly filling up. Efforts will be made to chain sites under construction, in which case reusable soil will end up directly at the right place without any intermediate storage.

Climate change adaptation is taken into account in construction. The city takes into account the shading needs of yards, gardens and buildings in service properties, such as schools and day care centres, when renovating and designing new ones. Shades are added by means of structural sunshades, shelters and green structure.

Objectives

  • The city’s service network plans and service facility network plans will be drawn up while minimising the carbon footprint and life-cycle costs. The efficient utilisation of the city’s service facilities will be optimised.
  • The climate neutrality criteria in use in construction will be applied throughout the land-use process (city plans, plot allocation data, building codes, complementary construction, incentives) as well as in the planning of the city’s own construction projects and in building maintenance.
  • The city will improve the energy efficiency of its own building stock while curbing in-service energy consumption. The energy consumption of facilities will decrease in proportion to the square metres used.
  • The city’s properties will be 80%climate neutral in terms of energy by 2025, provided that Tampereen Energia can produce an equivalent amount of climate neutral heat.
  • Infrastructure construction will utilise all materials that can be utilised.
  • Transport distances will have been minimised by ensuring adequate intermediate storage and circular economy hubs.
  • Renewable materials will be used in all suitable infrastructure construction sites. Work machines will run on low-emission fuels.
  • Construction will strive to meet the set emission goals through planning and by using construction carbon footprint calculations.
  • Guidelines will be created for buyers and operators to address climate and environmental issues.

Benefits addition to emission reductions

  • Fewer indoor climate issues
  • Protecting the value of buildings
  • Improved comfort of living
  • Promoting diverse urban development
  • Development of competence and business related to sustainable construction, such as wood construction
  • Promotion of competition in building materials
