Solutions and impacts of the eco-smart city

Challenges in construction and use of buildings

  • Taking climate change into account.
  • Efficiency in planning and execution of construction projects and problems with project scheduling and cost.
  • Waiting for plans.
  • Too little cooperation.
  • Lack of skilled labor and long-term work experience, lack of job motivation.
  • Overoptimistic and tight schedules.
  • Expensive construction and living.
  • For residents there is no clean nature nearby.
  • Accessibility, adaptability.
  • User opinions.
  • Quality Problems: Fast, product and production planning, site management.
  • Responsibilities at the construction site are fragmented.
  • Co-ordination.
  • Design during construction, overall view.
  • Buildings hide errors and no one takes responsibility for the whole.
  • Faults: Adjustment and tightness of balcony doors and windows, balcony structures and glazing, cracks in walls and ceilings, parquet installation, surface scratches and bumps, faulty bathrooms and tile joints, and adjustments to ventilation systems.
  • Strength of structures and moisture management.
  • Access to indoor air impurities and non-drying.
  • Damage to thermal insulation, air leakage between floor and wall.
  • Brick partition moisture damage. Incorrect installation of the windshield.
  • Incorrect installation of underlay on eaves.
  • Connecting the drain pipe to the radon vent pipe on the bottom.
  • Moisture condensation on the inside of a crawl space base wall.
  • Lack of fan replacement air.
  • Construction practices.
  • Building regulations set requirements for buildings with regard to energy efficiency, thermal and acoustic insulation and ventilation.
  • Modernizing work environments.
  • Data Model BIM.
  • Project Management Systems.
  • Better use of information technology.
  • Healthy construction.
  • Mould fungus houses.
  • Overoptimistic schedules, too short drying times, no weather forecast.
  • Dense construction and layered structures hide the moisture, resulting in mold problems.
  • The vapor barrier is poor, there are problems with ventilation, there are no working structures that affect the indoor air.
  • Disinfectant cleaners kill weaker microbes, leaving room for harmful microbes.
  • The indoor air quality, soil and climate affect the indoor air.
  • It is not worth building in areas that are free of pollutants such as traffic or industry.
  • Structural design and material selection must be made carefully.
  • Use the building as planned and correctly.
  • By making the wrong choice of materials, a renovator can make serious mistakes, mold fungus bombs.
  • When the house is manufactured under factory conditions protected from the weather, moisture damage during construction is avoided.
  • Delay in repairs can cause further moisture and mold fungus damage.
  • Failure to determine the condition of the building.
  • Even new homes have to be renovated for years.
  • Good quality water.
  • Well uranium and other harmful substances.
  • Sewage problems.
  • Water Effects.
  • Wastewater treatment methods.
  • Purified waste water is not hygienic.
  • Preservation of bacteria, viruses and protozoa in the environment.
  • Wastewater is a threat to the well and the beach.
  • Clogging of sewers.
  • Soil problems: Thick mildews, pressurized groundwater, backfill, sulphide clay areas, rocky cliffs, shoreline deposits, flood and collapse sensitive areas, boulders, hard moreine.
  • Poor soil research, lack of local knowledge, wrong grate thickness, height errors, well size and location errors, water supply line mismatches, pipe collisions, lack of pipe insulation and plan repairs, soil and construction site challenges, varying weather conditions, groundwater use.
  • Energy
