CHPA Mission statement
Our vision is for an energy system that is dictated by the consumers' needs rather than one that dictates to them, creating a more local, efficient and less costly energy system
Areas of focus:
Combined heat and power
Sustainable energy services
District heating and cooling

THE ROLE OF CHP AND DISTRICT HEATING
![Page 16: CHP, district heating and the role of decentralised energy in buildings](https://reader030.vdocument.in/reader030/viewer/2022032708/56812a83550346895d8e1993/html5/thumbnails/16.jpg)
Opportunity of energy inefficiency
Energy Flows in the Global
Electricity System
Source: IEA,CHP: Evaluating the Benefits of Greater Global Investment (2008).
2/3 of the fuel “we” use to produce power is wasted --
CHP can more than double this efficiency
![Page 17: CHP, district heating and the role of decentralised energy in buildings](https://reader030.vdocument.in/reader030/viewer/2022032708/56812a83550346895d8e1993/html5/thumbnails/17.jpg)
Why is CHP more efficient?

Voluntary scheme aims to launch by December 2014
Will set minimum standards for heat suppliers and customers
Customer service and reporting a fault or emergency
Joining and leaving procedures
Heat bill, heat charge calculations and heat charge comparator
Paying the heat bill and payment difficulties
Disconnection and re-connection process
Complaint handling and independent adjudication
Privacy policy and data protection

New small-scale CHP guidelines
CHP only provides benefits when it is installed and operated properly
Reputation risk to all parts of supply chain
Read and use CIBSE’s AM-12 Guidance
Energy audit to see if CHP right solution
Use reputable CHP supplier, with long-term O&M contract
Design properly to use CHP’s efficiency, low temperatures
Create a handover strategy with building users
