Assessment Prediction Checklist

Transcription

1 CORE CREDITS ONLY (Building Performance) ASSESSMENT PREDICTION CHECKLIST This pre-assessment checklist allows a quick evaluation of the likely rating to be achieved under a formal BREEAM Offices 2005 assessment (effective from 1 st November, 2004). The checklist is a simplified version of the full method, for this reason the final rating may vary. Assessment Prediction Checklist CORE CREDITS ONLY IMPROVEMENTS TO THE PREDICTION CHECKLIST IN 2005 Updated in line with BREEAM Offices 2005 manual NOTE: The prediction checklists only provide an estimate of a BREEAM rating. Predicted ratings are likely to change after a formal assessment by a licensed BREEAM assessor Copyright BRE The BREEAM name and logo are registered trade marks of Building Research Establishment Ltd.

2 USING THE CORE ASSESSMENT PREDICTION CHECKLIST This checklist should be used when carrying out approximate assessments on Vacant Buildings Buildings where a review of fabric and services only is required For these cases, the checklist produces an Environmental Performance Index only the detail is insufficient to produce an approximate BREEAM Offices rating. The credits included here are based on the CORE credits only, CORE credits assess the building performance. To generate an estimated rating for a Management & Operation assessment, please complete the separate checklist, MANAGEMENT & OPERATION Assessment Prediction Checklist.. Note : It is not possible to carry out a Management and Operation Assessment unless the building has been occupied and in operation for a minimum of a 12 months. To generate an estimated rating for a Design & Procurement assessment, please complete the separate checklist, DESIGN & PROCUREMENT Assessment Prediction Checklist. COMPLETION OF THE CHECKLIST Step 1 Step 2 Step 3 Step 4 Step 5 NOTE: Complete the checklist by entering the number of points (shown in the points column) into the light grey shaded box corresponding to the credit. At the end of each section, total the columns and enter in the boxes titled, Complete for all sections. Sum the totals from each column and enter in to the box titled Sum of points achieved in each column Box A corresponds with the total score under the category. Assess the score generated in Box A with the table titled Probable Environmental Performance Index Score the score achieved should gain an estimated rating of Make a note of this score. In some cases, there are multiple performance levels, simply award the points score corresponding to the predicted level of achievement.

3 HEALTH & WELLBEING Where cooling towers/evaporative condensers are designed to allow ease of access for cleaning, maintenance and replacement of parts or no cooling towers/evaporative condensers are specified. Where hot and cold water systems have been designed or actions taken to minimise risks of Legionellosis. Where external façade windows to office areas are openable and on at least opposite sides for accommodation over 7m deep. The openable area should be the equivalent of 5% of the gross internal area of the building. This should have an even distribution across the office area so as to promote adequate cross ventilation. Where steam humidification is installed OR where no humidification is present. Where air intakes serving occupied areas avoid major sources of external pollution. Where either: In the case of mechanically ventilated and air conditioned buildings, fresh air is provided at 12l/s/person OR In the case of naturally ventilated buildings, trickle vents are provided on the majority of windows, Where the window openable area is the equivalent to 5% of the gross internal area of the building and the plan depth is no more than 15m otherwise extra ventilation is required. Where at least 80% of net lettable office floor area is adequately daylit. Where occupants have a view out e.g.(field, atrium) with a maximum distance of 7m approx (2 desks spaces) to the nearest to window. Where an occupant controlled system of glare control (e.g. internal or external blinds) is fitted. Where high frequency ballasts are installed in all general office luminaries. Where the lighting design is in compliance with the addendum to Lighting Guide 3, Building Research Establishment Ltd. Nov 2004 /02/ of 10

4 Where control of lighting in office areas relates to circulation space, daylighting and is zoned to provide separate control for groups of no more than 4 workplaces. Where local control is available for temperature adjustment in office areas, to cope with different load requirements. Building Research Establishment Ltd. Nov 2004 /02/ of 10

5 ENERGY Where electricity sub metering is provided for substantive energy uses within the building covering lighting and small power, and each of the following where present: Computer Room Humidification Plant Cooling Plant Fans (major) If a building has other major energy consuming items, they should be covered as appropriate e.g. catering facilities. 12 Where electrical sub metering of tenancy areas is installed, or where the building is single tenant only. 12 Losses minus gains in kwh/m 2, will be predicted according to the fabric and form of the building. Credits are awarded based on the scale below: Above and below kwh/m 2 /year 0 Between +/ and 70 kwh/m 2 /year 12 Between +/ and 45 kwh/m 2 /year 24 Between +/ and 25 kwh/m 2 /year 36 Between +/ and 15 kwh/m 2 /year 48 Between 5 and 5 kwh/m 2 /year 60 Building Research Establishment Ltd.

6 TRANSPORT Total Net CO 2 emissions arising from transport to and from the building will be predicted based on location. Credits given are based on the scale below: RURAL location with TYPICAL public transport connections 0 EDGE OF TOWN location with TYPICAL public transport connections 22 SMALL TOWN location with TYPICAL public transport connections 44 CITY / TOWN CENTRE location with TYPICAL public transport connections 66 CENTRAL URBAN CONURBATION location with TYPICAL public transport connections CLOSE TO MAJOR TRANSPORT NODE location with TYPICAL public transport connections Where evidence can be provided to support the implementation of a Transport Plan. (Only add this score if less than 80 is scored above) Where there is provision of cycling facilities for 10% of staff ( 500 staff) Where there is provision of cycling facilities for 7% of staff ( 1000 staff) Where there is provision of cycling facilities for 5% of staff (>1000 staff) e.g staff require (0.1 x 500)+(0.07 x 500)+(0.05 x 300) = 100 cycle spaces Facilities are to include sheds / lockable storage and showers Additional points can be achieved where there is also the provision of changing facilities including lockers and a drying space Requirements are reduced by 50% near major transport nodes or remote rural areas. Where good access is available to public transport networks within 500m and with at least a 15 minute service frequency to a local urban centre.
