THE GREATEST CO_2 SAVING IS FROM CHP FUELLED BY BIOMASS

摘要

Biomoss and CHP do not necessarily go together. Today, CHP is typically gas-fired, while a biomass boiler usually generates just heat. But there may be an overlap in multi-fuel projects and also in the future we may see biomass-fired CHP, operating at a larger scale with the heat going to district heating. So looking at them together now seems sensible. Both biomass and CHP are affected by continuing changes in Building Regulations — particularly the energy requirements in new-build and refurbishment projects. Lower energy design is no longer defined solely by insulation and airtightness standards. This is partly because going beyond current building fabric standards will significantly increase the cost of projects. Furthermore, fabric measures only impact on one part of energy demand, namely space heating. Other energy uses, such as hot water, lighting and appliances now have bigger CO_2 impact than space heating. Low and zero-carbon technologies, such as CHP, and renewable energy sources, such as biomass fuels, will increasingly be used to improve building performance beyond the current Building Regulations.
