Delivering a Sustainable Future
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 [...]

The changing skyline of London – green roofs playing their part
More and more green roofs are being used in schemes, predominately driven through the planning process, especially in London. In this article we look at the benefits green roofs can bring to not only the development to which it belongs, but also the local area in which it is located. Green roofs have been around [...]

November 2010 Code guidance in practice
Our experience in using the most recent Code guidance issued in November 2010 has highlighted the following issues. ENE 8 The latest Code guidance requires communal cycle stores to meet various aspects of Section 2 of Secured by Design (SBD) New Homes 2010. These security requirements are mostly defined within the ENE 8 [...]

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 [...]
Why we should insulate corridor walls next to dwellings
Under Building Regulations 2010, corridor walls adjacent to dwellings can be classed as: a) A sheltered wall, if the adjacent corridor is unheated OR b) A party wall, if the adjacent corridor is heated Sheltered walls The u-value of a wall separating a dwelling with an unheated corridor must be considered as a ‘heat loss wall’ [...]
Building Regulations Part L1b: Improvements to existing dwellings
Building Regulations Part L1b: Conservation of Fuel and Power, applies to Existing Dwellings. The regulation is broad in reach and is intended to make notifiable any significant building modifications that are undertaken. The Approved Document for Part L1b gives guidance on the way in which compliance with the regulation may be demonstrated. The document is [...]
Implications of the new Code guidance
The latest revision to the Code for Sustainable Homes (CSH) was launched last month (Nov 2010). Schemes can be assessed under the former May 2009 version up until the 9th of December but after this date must use the new version, unless the scheme is being developed under the 2006 Building Regulations (Part L). It [...]
