London Plan moves to 40% carbon dioxide reduction on regulated energy

Posted on November 6th 2013

The Greater London Authority (GLA) has clarified that the move to a 40% CO2 reduction over Building Regulations Part L 2010 (London Plan Policy 5.2) came into effect from the 1 October 2013. This applies to both residential and non-residential development. The GLA is seeking this reduction on all referable schemes submitted after this date, and they encourage London Boroughs …

Masterplanning for District Heat Networks

Posted on June 19th 2013

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 The above factors are best …

CASE STUDY: CHP viability in domestic scenarios

Posted on September 3rd 2012

  In line with the London Plan, energy supply through CHP is becoming the norm in new London developments. The Mayor has introduced mandatory use of CHP in developments of 500+ dwellings through planning guidelines. Nonetheless, Richard Hodkinson Consultancy is experiencing an increasing number of London based Local Authorities demanding CHP on new residential developments, even on schemes as small …

Delivery of district heating on phased developments – things to consider

Posted on August 22nd 2012

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. 1.       Early development of a …

Should commercial units be connected to district heat networks?

Posted on August 7th 2012

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 reductions in CO2 emissions. To …

Part L and community energy averaging

Posted on January 19th 2012

Building Regulations require that all dwellings connected to a district heating network are apportioned the same CO2 reduction. This has significant consequences for phased developments where phases are subject to differing planning or Building Regulations requirements. It is important to consider this issue early in the build program to ensure that sufficient provision for Energy Centre space is designed into …

CHP design considerations

Posted on August 23rd 2010

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 not a constraint on the …

Biomass, deliveries and ash management

Posted on February 22nd 2010

How much more attention do biomass boilers really need? The comparison to the ‘stoker’ associated with coal fired steam engines may be unfair and extreme but it does go some way to painting a picture of the difference between biomass and gas fired boilers. Biomass (wood chip or pellet) is a solid fuel which requires more manual intervention than natural …

Community heating – costs to users

Posted on December 21st 2009

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 water system. On a recently …
