This allows us to reduce our Scope 2 emissions by around 2 tonnes per annum (CO2e). All the rest of our electricity is purchased from Ecotricity’s 100% renewables tariff and offset with Gold Standard credits from Hydrologic. Sustainable Furnishings During the renovations, our builders worked hard to send as little waste to landfill as possible. This ethos is echoed in the Hub’s furnishings, which include Interface’s ‘Net-Works’ carpet tiles made from discarded fishing nets purchased from coastal communities who collect them from the sea. Living Wall The Hub’s facade features one of Bristol’s largest living walls. The plants growing on its vertical surface make a contribution to cleaning the air at this busy traffic intersection. Air Conditioning & Heat Recovery Look up and you’ll see our highly efficient Mitsubishi R32 air conditioning system—the first of its kind installed in the UK. It uses R32 refrigerant gas that has a relatively low global warming potential (GWP) to heat and cool the building as required. It’s also paired with three Mitsubishi Lossnay MVHR* units. These reduce our heating bills and Scope 1 emissions by recovering up to 80% of the heat from the stale air they remove from the building and using it to warm up the fresh air they pump back in. *MVHR = Mechanical Ventilation with Heat Recovery 54
