New dwellings (approved document L1A)<br> <br> These are the main ways in which compliance is calculated:<br> 1. Calculate the TER (Target CO2 Emissions Rate) for the dwelling, by substituting in the designed dwelling standard U-values (Table 2 on page 19 of the Approved Document) , glazed area, air infiltration, Air permeability, heating and fuel , and apply an improvement factor (currently 20%)<br> 2. Calculate the DER (Dwelling CO2 Emissions Rate) with the parameters as required by the actual design, subject to some limiting conditions.<br> If the DER is better, i.e less than, the TER, the dwelling complies with this part of Part L.<br> 3. Calculate the SAP rating.<br> 4. Check internal and external lighting meets requirements.<br> 5. Calculate summer condition to demonstrate that there is no tendency to high summer temeratures.<br> <br> The assessment should be made for the design and again for the completed building.<br> <br> B. Work in existing buildings (approved document L1B)<br> <br> 1. EXTENSIONS TO DWELLINGS:<br> a) Approach 1 - very simple<br> If the openings in the extension are less than 25% of floor area of the extension, ensure than U-values in extension meet standard values (Table 4 on page 22).<br> <br> b) Approach 2 - quite flexible<br> Show that the average U-value of the extension is better than the extension would be with standard U-values and openings area.<br> <br> c) Approach 3 - most flexible<br> Show that the CO2 emissions from the whole extended dwelling are no more than they would be for the dwelling with a notional extension built to standard U-values and openings. (Any improvement in the main dwelling cannot be included in this calculation, but is dealt with separately as below).<br> <br> 2. MATERIAL CHANGE OF USE:<br> If a dwelling is made in an existing building:<br> a) Simple method<br> New and replacement elements must meet thermal standards (Table 4 on page 22).<br> Retained elements must be upgraded if they are outside U-value threshold values (Table 5 on page 23).<br> b) More flexible method<br> Show that the total CO2 emissions are no worse than if the rule above had been followed. This allows for renewable energy sources, etc, to offset U-values.<br> <br> 3. MATERIAL ALTERATIONS:<br> When a dwelling is altered:<br> a) Show that retained and new thermal elements meet U-value criteria of Table 4 on page 22.<br> b) Ensure that retained thermal elements are upgraded if outside threshold limits of Table 5 on page 23, if economically feasible.<br> <br> NOTES:<br> <br> <br> 1. U-Value criteria:<br> <br> The regulations look separately at:<br> a) Individual parts of the roof, walls and floors (i.e roof type 1,2 etc)where these differ in U-value.<br> b)The area-weighted average U-value of the whole roof, wall and floor.<br> There are different limits for each type and for the average.<br> <br> 2. Air infiltration:<br> <br> For existing buildings a method of compliance is for work to be to Robust Details.<br> For dwellings in new buildings:<br> Either show by testing that air infiltration is less than 10 m3/hm2 at 50Pa<br> Or show by testing it is no worse than the infiltration used in the compliant DER calculation<br> Or (if no more than 2 dwellings of the type on a site) use a design value of 15 m3/hm2 in the DER. Compared with figure of 10 m3/hm2 this will necessitate improvements elsewhere to compensate.</font></b> <div> <hr size="2" width="100%" align="center"></div> <br /> <br> <a name="Building_Regulations_2006_L2" id= "Building_Regulations_2006_L2"></a> <h3>OUTLINE OF PART L2, for NON-DOMESTIC BUILDINGS</h3> <br /> <br> L2A NEW BUILDINGS<br> For new buildings calculations are required using BRE's SBEM program, or an approved equivalent. SBEM calculates all the L2 requirements for new buildings except for solar gain under Clause 64. I provide SBEM calculations and include further calculations for solar gain, to CIBSE publication TM37 as approved in Part L2 . I provide the stipulated Compliance Checklist.<br> L2A permits re-submission of calculations 'as built' on completion, showing that the building still complies, if air permeability is poorer than designed.<br> <br> PART L2B EXISTING BUILDINGS<br> 1) MATERIAL CHANGE OF USE<br> For a change of use, the approved document allows a means of compliance under L2b Clause 36. This sets standards for U-values of thermal elements and for heating, hot water , and lighting services.<br> If it is not possible to achieve compliance under Clause 36, greater flexibilty is allowed under Clause 37. For this calculations have to show that the CO2 emissions are no greater than if Clause 36 had been followed. This requires two sets of SBEM calculations, one as proposed and the other notional to Clause 36.<br> <br> 2) MATERIAL ALTERATION<br> For alterations, the approved document allows compliance under L2b Clause 39. This sets standards for U-values of altered thermal elements and for altered heating, hot water , and lighting services.<br> An SBEM calculation is not required. In difficult cases it is possible to provide an economic feasibility assessment to support a proposal.<br> <br> 3) EXTENSIONS<br> In accordance with L2b clause 25, for an extension of over 100m2 and more than 25% of floor area of the existing building an L2a calculation should be provided. Additionally, if the existing building has more than 1000m2 of floor area, consequential improvement in the existing building is necessary per Section 1 of L2b.<br> My calculations will include 1) SBEM output and 2) calculations for solar gain to TM37, required under L2a Clause 64, plus the Compliance Checklist <div> <hr size="2" width="100%" align="center"></div> <br /> <br> <div align="center"> <hr size="2" width="100%" align="center"></div> <p>Kce associate with architects, building designers, building owners and operators</p> <div align="center"> <hr size="2" width="100%" align="center"></div> <p><b>KCE energy and environment</b></p> <p>Ecohomes </p> <p>Housing designed to a suitable Ecohomes rating displays a recognised energy and environmental standard. Ecohomes is the homes version of BREEAM (Building Research Establishment Environmental Assessment Method). This scheme was launched in 2000, and Stephen Kinsella is a BRE licensed assessor and advises on designing to achieve Ecohomes ratings.</p> <p>The Ecohomes assessment method demonstrates the sustainable credentials of the development, ensures that the environmental criteria are followed through the finished development, and demonstrates superior environmental design to architects new homeowners and other stakeholders. Ecohomes provides an Ecohomes rating certificate for every home. </p> <p>Ecohomes is quality managed by Building Research Establishment. Ecohomes takes into account broad environmental concerns of climate change, resources use and impact on ecology and biodiversity, alongside the need for a high quality of life and a safe and healthy environment. Ecohomes guarantees an independent and authoritative standard. The approach is realistic and straightforward, based on Bre's experience of what practically can be achieved.</p> <p>The sustainability and energy features of the development, such as transport, ecological benefit, and water use, as well as these features which are inherent in the construction, are assessed within the Ecohomes rating. Some other features that are taken into account are minimising pollution through selection of building materials, use of locally sourced materials, and embodied energy (the energy used in manufacture of building materials), re-cycling of waste, and absence of light pollution.</p> <p>Kce gives a full service in achieving Ecohomes standards and advising on the environmental principles of the scheme.</p> <p><b> Energy surveys </b></p> <p><b>The Climate Change Levy</b> (CCL) has added between 11% and 13% to the average fuel bill since April 2001 <b>Energy used,</b> not cost, forms the basis of the Climate Change Levy - the only way to reduce the effect is to reduce fuel consumption. <b>Some trade sectors have signed to Sector Agreements,</b> whereby they agree to reduce energy consumption and pay up to 80% reduced CCL.
