SOLUTIONS TO REDUCE EMISSIONS

Deploying a sustainable system

Heating and air conditioning are significant items on your energy bill. Traditional heating and cooling systems often rely on non-renewable energy sources, resulting in significant greenhouse gas emissions and increased energy costs. District heating systems offer efficient, scalable and flexible solutions for reducing carbon footprints compared to gas or oil heating systems by integrating renewable energy sources, using combined heat and power plants, and optimising heat production and distribution, resulting in reduced emissions and environmental impact.

  • Replace gas and/or fuel for heating with district heating (e.g. GeniLac and/or Geniterre)
  • Replacing gas and/or fuel for heating with heat pumps
  • Replace electric heating with district heating and/or heat pumps

Resources

Thanks to improvements in photovoltaic performance and rising costs, it is possible to produce clean, renewable energy on site. Our buildings have significant potential for solar energy production to meet their daily energy consumption. It is possible to make your building more ‘green’. Start by measuring and assessing the solar potential of your building.

  • Measure the solar potential of your building with the Geneva online solar cadastre (SITG)
  • Conduct an in-depth study of your building’s solar potential
  • Install photovoltaic solar panels on the roof and/or facades of your building.
  • Install solar thermal panels on the roof and/or facades of your building.

Recycled materials, such as reclaimed wood or recycled steel, help divert waste from landfills and reduce the need for resource-intensive extraction and manufacturing processes. In addition, bio-based materials, such as bamboo or cork, come from renewable sources that absorb carbon dioxide during their growth. By choosing these sustainable alternatives, we can reduce the carbon footprint associated with traditional building materials and contribute to a more circular and environmentally friendly construction industry.

  • When renovating or constructing new premises, prioritise the use of recycled or bio-based materials.
  • When insulating premises, prioritise the use of bio-based materials.

Improving efficiency

The building envelope is vital for energy savings because it acts as a barrier to minimise heat transfer and air leakage between the interior and exterior. Thanks to good insulation and high-performance windows, it reduces excessive heating and cooling requirements, resulting in lower energy consumption, cost savings and a reduced carbon footprint. A well-designed envelope improves indoor thermal comfort while effectively reducing potential energy waste.

  • Replace broken windows
  • Place weatherstripping on old windows, either by keeping some joints open or by arranging for parallel ventilation.
  • Fit automatic closing systems on doors, install airlocks
  • If the building is air-conditioned or if the building is not air-conditioned but overheats in summer: install external sun protection.

We use many electrical appliances in our daily lives. This equipment is essential, but it can consume much more energy than necessary. Excessive unused capacity, idling and low energy efficiency are all factors that lead to energy waste. By selecting energy-efficient products, rationally programming the operating system, upgrading old software, and changing behaviours and methods of equipment use, it is possible to effectively reduce the energy consumption of various electrical equipment in the building.

  • Commercial kitchen equipment
    • Cooking station: replace direct electric hobs with induction hobs; implement a cooking schedule to avoid using hot cabinets for storage after cooking; size cooking equipment according to actual needs.
    • Washing station: delay the start of washing until off-peak hours (if possible)
    • Refrigeration: heat recovery (compressor) and/or optimisation of operating mode; reduction in capacity/use
  • Lifts
    • Check the ventilation rate of the lift shaft
    • Install an energy recovery system during braking
  • Computer equipment
    • Replace mechanical hard drives (HDD type) with solid-state drives (SSD type)
    • Increase the cooling temperature of server rooms
    • Regulate the amount of air distributed by variable control systems (frequency variation)
  • Laundry room (washing/drying)
    • Choose appliances with an A or A+ energy rating.
    • Choose equipment with an A or A+ energy label.
    • Preferably connect laundry equipment to a heat pump.

Reducing demand for services

Buildings are currently responsible for 39% of global energy-related carbon emissions: 28% of operational emissions, due to the energy required to heat, cool and power them. In Geneva, buildings occupied by businesses and residents are responsible for half of local CO₂ emissions.

A comfortable indoor environment is essential for people’s physical and mental wellbeing, as well as for their work and daily lives. Heating accounts for two-thirds of a household’s energy needs. Unfortunately, in current heating and cooling systems, a significant amount of energy is wasted, for example during periods of non-occupancy or in unoccupied spaces. It is entirely possible to reduce this excessive energy consumption through practical technological design or behavioural changes.

Good pipe insulation minimises heat transfer, preventing heat from escaping in winter and pipes from overheating in summer. Programmable thermostats allow users to set specific temperature schedules, thereby reducing energy consumption when spaces are unoccupied or adjusting settings based on occupancy patterns.

  • Reduce heating during the night and at weekends, holidays, days off, etc. (if necessary, a programmer or optimiser can be installed)
  • Insulate pipes in unheated areas.
  • Correct the heating curve settings
  • Reduce the power of burners when they are oversized.
  • Install thermostatic control valves in all rooms.

Resources

In the office, the main sources of electricity consumption are lighting and electronic office equipment such as computers and printers. By replacing these devices with more energy-efficient and environmentally friendly products, and switching off the electricity when no one is using it to reduce unnecessary waste, we can effectively reduce electricity consumption in the office. Small everyday actions can also make a big difference.

  • Replace fluorescent tubes with LED tubes
  • Install timers in rooms that are used intermittently (bathrooms, corridors, car parks, etc.).
  • Break down the network into uniform lighting zones: in a room, independent management of lights near a window.
  • Switch off all computers at night
  • Reduce the number of printers (e.g. by concentrating them in one area/floor rather than in each office)

Resources

Buildings are currently responsible for 39% of global energy-related carbon emissions: 11% come from materials and construction. The construction sector is still often not very climate-friendly. Carbon emissions released before the use of the constructed asset, known as ‘upfront carbon’, will account for half of the total carbon footprint of new buildings by 2050, threatening to consume a large portion of our remaining carbon budget. The built environment sector therefore has a vital role to play in responding to the climate emergency, and it is essential and urgent to tackle the issue of initial carbon.

  • New buildings
    • Extending the lifespan of buildings
    • Reducing the surface area of building elements by adopting a compact building design
    • Choose the lightest insulation materials possible
    • For interior walls, choose cement bricks or sand-lime bricks rather than clay bricks. For lightweight walls, choose wooden studs rather than metal profiles.
  • Conversions and refurbishments
    • Take into account the different lifespans of the various building components when planning long-term works.
    • When renovating, it is important to bear in mind that adding new elements and materials will increase the building’s intrinsic energy.
    • Prioritise simple, locally sourced materials that have not consumed a large amount of energy during their production.
