Masterplanning for District Heat Networks

The location and timing of the provision of Energy Centres on large multi-phase development sites with district heat networks is complex as there are a number of often competing factors: – Overall capital cost Cash flow Operational efficiency & costs (which influences resident energy costs) Phasing flexibility Matching Energy Centre output to development heat demand [...]

Delivery of district heating on phased developments – things to consider

District heat networks (generally with CHP) are increasingly common for medium and large scale developments in order to provide the CO2 reductions necessary for planning policy and Building Regulations compliance. Delivery of these networks on phased developments is complex. For effective delivery, it is important to consider a number of issues at an early stage. [...]

Should commercial units be connected to district heat networks?

Many predominantly residential developments also contain small ground floor commercial units. Where district heating (including CHP) is proposed for the dwellings, planning authorities generally seek for the commercial units to also be connected. We have concluded that this is not necessarily technically appropriate or viable. The aim of district heating with CHP is to facilitate [...]

CHP versus biomass: air quality

On many of our projects we are faced with a choice between Combined Heat and Power (CHP) and biomass boilers as the best way to achieve reductions in CO2. There is a widely held view that biomass is bad and CHP is good in terms of air quality. Oxides of nitrogen (NOx) and particulate matter [...]

CHP design considerations

The following issues should be considered at an early stage of design as part of an evaluation of the viability of CHP. Organising a connection to the grid Unless a CHP engine can be connected to the grid, its size may be significantly reduced. This is so that demand for electricity across a development is [...]

Community heating – costs to users

Evidence is emerging about the high running costs for community heating schemes that are required to meet planning   requirements. Often these include Combined Heat and Power facilities and biomass boilers in addition to the more  conventional gas boilers. Heat meters are used within each dwelling to measure the heat energy provided through the  circulating hot [...]

Masterplan strategies and the Code

For most schemes, the mandatory energy elements of the Code can be achieved through the incorporation of solar thermal and/or solar PV panels on individual houses. Once Code Level 4 (a 44% improvement on 2006 Building Regulations) is sought, serious consideration must be given to a community heating network with either biomass or CHP facilities. [...]
