Energy source carbon intensity
Connect to an existing local heat network
- connection to available local heat network, e.g. nearby CHP plant, other waste heat source, etc (3 - section DS3)
Integrate on site CHP
- for refurbishment projects integrate CHP in the existing systems if these are not being replaced (4 - section 5.3.1.2, 12)
- CHP as a boiler replacement option (7)
Design building systems to use the energy sources with the lowest lifetime carbon emissions
- energy source (fuel) selection for each end use based on carbon emissions (4 - table 5.2, 6 - section 5, 5 - section 6, 8 - section 6)
Study renewables options early in the design process
- renewable feasibility study covering technical feasibility and economic viability of available renewable energy technology options (4 - section 5, 10, 13 - section 4, 11)
Purchase green electricity
- green electricity (9)
Study CHP options & feasibility early in the design process
- CHP options appraisal followed by full feasibility study (4 - section 05/03/01, 1, 2, 14)
Integrate on site renewable energy generation technologies
- roof-mounted photovoltaic panels (15)
- building integrated photovoltaics (bipv, e.g. PV slates, rainscreen cladding, glazing, etc.) (15)
- solar water heating (main types: flat plate or evacuated tube collectors) (10 - section 3.6)
- ground source heat pumps (main ground pipe options: horizontal coil, vertical borehole, or energy piles) (10 - section 3.9)
- ground source cooling (main types: closed loop/reversible heat pump or open loop - ground/river/lake water cooling) (10 - section 3.1)
- small scale or micro- (including building-mounted) wind turbine(s) (10 - section 3.4)
- biomass heating boiler(s) (10 - section 3.7)
- biomass CHP (10 - section 3.8)
