Energy Savings Opportunity Scheme (ESOS) Regulations 2014
The UK Government has introduced a new mandatory energy assessment and energy saving identification scheme for large organisations in the UK. The scheme is applicable to organisations that have more than 250 employees or an annual turnover of ≥ £40m.
Organisations first energy assessment must be completed by the 5th of December 2015 and should include; measurement of total energy use from buildings, transport and industrial processes, identification of cost effective energy efficiency recommendations and notifying compliance to the Environment Agency through formal reporting.
TÜV SÜD Wallace Whittle have a team of experienced accredited Energy Assessors who are able to deliver a number of the routes to ESOS compliance including the provision of full energy audits.
BREEAM 2014 & Refurbishment
The BREEAM scheme was revised in May 2014 and all new assessments in England & Wales will now be assessed under the new criteria. The BREEAM criteria has become more onerous making it tougher still to achieve each rating with the intent of subsequently improving environmental standards across the industry. The approach to energy reduction has been adapted to follow an energy hierarchy providing more accessible reward for passive design and energy efficiency measures.
BREEAM 2014 shall be rolled out in Scotland in line with the changes to the building regulations in late 2015. Teams can opt to use the criteria in the meantime.
The new BREEAM UK Non-Domestic Refurbishment and Fit-Out scheme is also now live and is able to assess and improve the sustainability of refurbishment and fit-out projects. It is tailored to take account of the challenges of improving existing buildings ensuring projects are assessed against the issues that can reasonably be expected to influence.
TÜV SÜD Wallace Whittle have a team of experienced accredited BREEAM Assessors and are happy to provide informal seminars within your office if you would like a more detailed update on the changes within these BREEAM Schemes. If you would like to arrange a seminar please contact email@example.com.
Building Regulations Part L2 2013
The updated Part L2 Building Regulations for England became live in March 2014 and we have now had opportunity to apply the new Building Regulations and associated software to assess a number of projects.
Overall the revision requires an aggregate 9% carbon emission reduction from the 2010 version which varies depending on building type. A typical office requires a 12% further reduction and an industrial or retail unit 4% and 8% respectively.
Our typical route to compliance follows an energy hierarchy focusing on passive and then active strategies which have included the following measures which are now incorporated into the notional building which we are benchmarking against; reduced lighting power densities, automatic lighting control in all areas, improved equipment efficiencies and demand based control.
The next update to the English Building Regulations is proposed for 2016 and includes a further 20 to 30% carbon reduction.
Scottish regulations are programmed to be amended in October 2015 after CO2 reduction changes were deferred in 2013. A 43% reduction on current standards is predicted.
TÜV SÜD Wallace Whittle have a team of experienced accredited Energy Assessors who are able to deliver a number of routes to Building Regulations compliance via comprehensive feasibility studies and energy strategies.
Climate Based Daylight Modelling (CBDM)
CBDM takes account of the quality and quantity of daylight available using sun and sky conditions derived from actual weather data for a site simulated over an annual time series. This is an improvement on the traditional daylight factor analysis which is a simplified process based on a static overcast sky condition. The CBDM calculation is a key requirement in the design of the new Priority Schools programme in England and Wales.
CBDM allows the natural light distribution and intensity to be assessed in greater detail to maximise the use of daylight in occupied spaces. Predictions of absolute illuminance can be made based on location, orientation, fenestration configuration, space geometry and surface properties.
The key output criteria measure the following:
Useful Daylight Index (UDI) which is defined as the annual occurrence of illuminances across the working plane that is in a lux range considered useful by the occupants.
Daylight Autonomy (DA) which indicates the amount of time a space can expect to achieve a target illuminance level on the working plane. This criterion is aimed at delivering an energy efficient space.
The sustainability team at TÜV SÜD Wallace Whittle can provide key advice on how to achieve the CBDM standards and carry out simulation analysis. For further information please contact us at firstname.lastname@example.org
Our first Code Level 5 Residential Scheme
We have completed our first Code for Sustainable Homes Level 5 scheme. The Level 5 Townhouses located at Surrey Lane London are being constructed by Lend Lease.
Dynamic thermal modelling was used to develop the energy strategy for the dwellings which require a 100% CO2 reduction from Part L1A Building Regulations in order to meet the Level 5 mandatory requirements.
The thermal modelling concluded the following recommended design approach for each Townhouse:
Building fabric U Values from 0.12 to 0.1 W/m2K Air Permeability level equal to 1m3/h/m2@50Pa Combined Heat and Power system (CHP) Solar Photovoltaic Panels (PV) TÜV SÜD Wallace Whittle were employed on this project as M&E Consultant, Sustainability Consultant and Code Assessors.

Edinburgh St James
TÜV SÜD Wallace Whittle are engaged as consultants on this major redevelopment of the St James Centre in the centre of Edinburgh.
The exciting proposals will provide a new city quarter with a 3 storey galleria with mixed use residential, hotel, cinema and retail accommodation approximately tripling the space and modernising this key part of the city.
Our Sustainability Team have prepared an energy strategy to meet the strict local authority energy policies. Highlights of this strategy include:
Central tri- generation providing district heating and cooling on site BREEAM ‘Very Good’ targeted If you would like to any further information regarding this project please contact us.
Heygate Estate, Elephant & Castle, London
TÜV SÜD Wallace Whittle have been appointed as Mechanical, Electrical and Sustainability Consultants for the Masterplan, Trafalgar Place, One the Elephant and Phase 2 of the Heygate Estate re-development.
Totalling 2,469 homes, 16,750m2 of retail, 5,000m2 of business space and 10,000m2 of community, culture & leisure floor space over a 13 year construction period.
Elephant & Castle Masterplan Phase 2 (MP2) is a residential development across two plots providing circa 500 homes and is the largest of the phases. The scheme includes a 30 storey and 20 storey tower. The development also includes retail, gym and underground car park.
All heating and hot water requirements shall be provided by the nearby proposed Heygate Energy Centre.
The development is designed to achieve a high level of energy performance through a combination of passive and energy efficient measures. The Lean, Clean, Green energy
strategy dictates that certain performance criteria are achieved from the building itself in response to solar gain and heat loss.
TÜV SÜD sustainability consultants have worked closely with the design team in order to assist in U-value calculations and thermal bridging calculations, particularly onerous when building at height. All dwellings will achieve Code 4 and over a 40 % Carbon Dioxide reduction from Part L 2010 calculations.

Water Source Heat Pump Scheme(s)
The Department of Energy & Climate Change (DECC) have asked the TÜV SÜD Sustainability Team to input into the consultation of the expansion of Water Source Heat Pumps (WSHPs) in the built environment.
Given the current predicted future impact of the ‘greening’ of the national grid for electricity, DECC are keen on integrating more heat pump technology into the UK marketplace.
TÜV SÜD MEP and Sustainability consultants have recent experience of a refurbished office block opposite the ExCeL arena, which is proposing to utilise dock water for heating and cooling purposes and thus contributing to an overall 20 % Carbon Dioxide reduction from Part L 2013 calculations.
