The New Students' Centre will not only be a landmark building for the School, it will also be one of the 'greenest' building on the campus.
Sustainability has been a key factor in the building design and the environmental objectives for the project may be divided into key categories; targets which must be met as a part of the brief and targets to which LSE have an aspiration.
Minimum of BREEAM Excellent rating, certified through BREEAM "Higher Education".
EPC Grade A, i.e.: an Asset Rating of less than 25.
DEC Grade A, i.e.: an Operational Rating of less than 25.
NUS Sound Environmental Impact Awards.
BREEAM Outstanding rating, certified through BREEAM "Higher Education".
90% of construction waste should be diverted from land fill.
is the Building Research Establishment's Environmental Assessment Method. A minimum requirement has been set for the project to achieve a BREEAM rating of 'excellent' with an aspiration of 'outstanding'. To achieve this, significant measures must be taken and these tend to be expensive, so the School has taken the unprecedented step of making a £1million provision in the budget specifically earmarked for these measures.
In order to meet the brief of achieving BREEAM 'Excellent' rating, a total of 70% must be achieved, whilst 85% is the minimum level necessary for a BREEAM 'Outstanding' rating. We are very pleased to report that the building is currently on target to achieve an Outstanding rating.
The diagram summarises the percentage credits, within each category, achieved by 04th April 2011.
EPC Rating: The building is required to achieved an EPC rating 'A', making it the most energy efficient building on campus. This has been calculated on the basis of the stage E design information, achieving an asset rating of 24 which corresponds to an asset rating of 'A'.
In essence, the building 'as designed' achieves:
72% reduction on annual heating loads compared to the Reference Building
27% reduction on annual energy demands for Domestic Hot water compared to the Reference Building
39% reduction on annual energy demand for lighting compared to the reference building
The building produced 67% of its demand for electricity though on site generation (excluding small power).
The graphs represent a breakdown of the Consumption and Carbon Emissions of the New Student Centre Building, reflecting the design at the end of Stage E.
DEC Rating: A DEC rating is determined after the first year's operation of a building, and is based on a comparison of the building's energy consumption over that year compared to an appropriate reference building.
It is essential to note that whilst the building can be designed to be a low energy building, the actual performance of the building in reality depends heavily upon its users. So it is critically important that the building's occupants are adequately aware of how the building should operate so that it reaches its full design potential. This is particularly relevant in terms of the use of additional equipment in the building and the impact this has on the electricity demand and resulting carbon emissions.
