Addressing Corridor Overheating on Developments with Community Heating

The increased use of community heating and CHP in residential apartment schemes can lead to excessive overheating in corridors. Our dynamic modelling estimates that temperatures can reach 50oC unless mitigation measures are designed in from the outset. The heat gains are due to hot water being circulated throughout ceiling voids in the corridors and risers [...]

Glazing Implications of Part L1A 2013

Glazing is already a key focus area for environmental assessment, driving internal daylight levels, thermal comfort, and overheating risk.  Our initial assessment using Part L 2013 shows the increasing importance of early consideration of the energy and CO2 impacts of glazing design. The strategic issue is that the benchmark notional building used in SAP 2012 [...]

Energy Efficient Street Lighting as an Allowable Solution?

The emerging requirements for allowable Solutions will be an extra cost to housing developers. In addition to potentially being a cheaper alternative to Allowable Solution payments, by providing on-site Allowable Solutions, developers can realise a benefit from this cost. Allowable Solutions are expected to be necessary to achieve the ‘zero carbon home’ standard that is [...]

The Increasing Importance of Thermal Bridging

Thermal modelling of construction details is a key tool for developers seeking to comply with the new fabric standards for Part L 2013 and address the technical concern of surface condensation risk. This will become increasingly valuable when statutory fabric performance requirements are introduced in April 2014. Using 2D and 3D thermal modelling software, we [...]

The use of new simulation techniques for building design optimisation

As heightening legislative pressures demand significant improvements to building performance standards, we face growing challenges when attempting to design low energy buildings within escalating design and budget constraints. Designers are therefore faced with the task of striking a balance between competing objectives. Richard Hodkinson Consultancy is currently undertaking research to test a method for establishing [...]

Ventilating dwellings in noise exposed areas

Developers must carefully consider the technical impacts of any planning requirements which preclude the use of openable windows in residential developments.  The limited technical solutions currently available mean that any such requirements will severely constrain the ventilation strategy and have a direct impact on Part L1A CO2 compliance. Where planning requirements for developments in areas [...]

The Benefits of Dynamic Simulation Energy Modelling at Concept Design Stage

A recent dynamic simulation exercise for a client has highlighted the importance of early consideration of a “joined-up” building services and fabric strategy. This ensures an optimised heating solution delivers comfort and acceptable running costs. The use of our dynamic simulation energy modelling software greatly improved the accuracy of this process over standard SBEM compliance [...]

Improving thermal bridging for a mid-floor apartment: a case study

Undertaking Part L 2010 assessment over multiple projects has taught us that it can be difficult to take advantage of improved ‘thermal bridges’ for some building types. For most dwelling types, Accredited Construction Details (ACDs) should provide a 50% reduction in thermal bridging heat loss compared to the SAP worst case.  However, we have found [...]

Running costs of energy in a Code Level 4 home

Meeting higher sustainability standards, such as Code for Sustainable Homes Level 4, does not necessarily mean lower energy costs to residents. The strategy adopted to achieve these higher standards can have a significant impact. It is possible for energy running costs to be increased if inappropriate strategies are adopted. We have examined the estimated energy [...]

Window lintels and Part L

We have undertaken a desktop study to test the significance of lintel performance on the outcome of Part L assessment. The study was based on the 2010 version of the Building Regulations for new homes. We conclude that selecting lintels with a view to their thermal performance can be of real advantage to designers seeking [...]

Assessment of thermal mass gives Part L 2010 advantage

A review of the treatment of thermal mass under Building Regulations Part L1a suggests that, rather than relying on default assumptions, there is an advantage to be gained by undertaking an individual dwelling assessment. The results of a thermal mass parameter assessment are similar for a range of house types on the same development. This [...]

Lighting design for Part L Compliance

Addressing the energy demand and associated CO2 emissions from lighting is a key element in complying with Part L of the Building Regulations (2010). Good lighting design is fundamental to cost-effectively meeting the standards. Furthermore, there are added benefits of a good lighting design in terms of occupant comfort and potentially lower running costs. Good [...]

Energy improvements at Parkview and Sunrise Estate

  We were recently commissioned to carry out an Energy Audit for a community led refurbishment project in the London Borough of Havering. The aim of the project was to ensure that any future upgrades to the energy performance of the three 1960s tower blocks on the Parkview and Sunrise Estate are undertaken to the [...]

Thermal mass: more complex than it first seems

The effects of thermal mass on a building are not straightforward. The effects of high thermal mass can be positive or negative depending on the fabric specification of a building. The graph below illustrates the effects of thermal mass on a semi-detached dwelling, by showing the change Dwelling Emission Rate (DER, measured in kg CO2/m2/yr) [...]
