5.2 Introduction

District Heating & Cooling is obviously not prime energy.

District heating & cooling might be coming from a location some kilometres away and may be run by a utility company, a cooperation or a local community. District heating & cooling could also come from a CHP station on site.

District heating or cooling plants may be part of a large power station. Some district heating plants may only produce heat from oil, gas, geothermal wells, bio-gas, pellets, straw, etc.

Ultimately the CHP station will be run in some commercial form and from the contractual and commercial point of CM, tenants and owners of a retail mall there may be no difference whether the district heating is on site or not. The provided heating or cooling energy has to be paid for.

District heating & cooling may have some advantages in investment and even in running cost. However, CM, tenants and owners will have little influence over the cost charged and less alternatives to choose if cost go up dramatically for some reason.

Such systems also need to be scrutinised in respect of risk and supply stability.
