Issue

4.2 Thermal Comfort

Aim

To ensure that appropriate thermal comfort levels are achieved through design, and controls are selected to maintain a thermally comfortable environment for occupants within the building.

Guidance

In order to meet the Standard for New Build and Renovation: The strategy for proposed heating/cooling system(s) demonstrates that it has addressed the following:

Zones within the building and how the building services could efficiently and appropriately heat or cool these areas (e.g., consider the different requirements for the central core of a building compared with the external perimeter adjacent to the windows).

The amount of occupant control required for these zones, based on discussions with the end user (or alternatively specific design guidance, case studies, feedback) and considers: o User knowledge of building services. o Occupancy type, patterns and room functions (and therefore appropriate level

of control required) o How the user is likely to operate/interact with the system(s) (e.g., are they

likely to open windows, adjust radiator settings, change air conditioning settings).

o The user expectations (e.g., this may differ in the summer and winter; users tend to accept warmer internal conditions in the summer) and degree of individual control (i.e., obtaining the balance between occupant preferences, for example, some occupants like fresh air and others dislike drafts)

How the proposed systems will interact with each other (where there is more than one system) and how this may affect the building occupants thermal comfort.

Evidence Required

Relevant section/clauses of the building specification or contract from the design team.

Thermal comfort strategy highlighting the points that have been considered and decisions taken accordingly.


Thermal comfort: defined in ISO 7730 as ‘that condition of mind which expresses satisfaction with the thermal environment'. The term ‘thermal comfort’ describes a person’s psychological state of mind and is usually referred to in terms of whether someone is feeling too hot or too cold. Thermal comfort is therefore difficult to define because it needs to account for a range of environmental and personal factors in order to establish what makes people feel comfortable. The purpose of this issue is to encourage appropriate and robust consideration of thermal comfort issues and specification of appropriate occupant controls to ensure both maximum flexibility of the space and thermal comfort for the majority of building occupants.

4.3 Acoustic Performance

Aim

To ensure the acoustic performance of the spaces meets appropriate standards according to those required by the character of the spaces.

Guidance

In order to meet the Standard for New Build and Renovation, as a minimum: 1. Indoor ambient noise levels, with the windows closed comply with the following:

Maximum Ambient Noise Level (dBA) LAeq - for 1 hour (night)

37 Bedroom

40 Living room or workroom

2. Pre-completion acoustic testing is carried out by a suitably qualified expert to ensure that all relevant spaces (as built) achieve the performance standards required, and any required remedial works in spaces that do not meet the standards are completed prior to handover and occupation.

Evidence Required

A copy of the design plan for each level of the building with each room/area clearly labeled.

A copy of the specification clause or acoustician’s calculations confirming: o Indoor ambient noise levels in each relevant room/area. o The standards to which calculations/measurements have complied, or are

required to comply with.

A copy of the specification clause or a formal letter from the project team confirming: o A programme of pre-completion acoustic testing by a suitably qualified

acoustician will be commissioned. Notes and References

Measurement/calculation procedures: The following procedures must be followed by the acoustician when measuring or calculating the levels required to demonstrate compliance:

o Noise from both internal sources (e.g. mechanical ventilation systems, plant noise) and external sources (e.g. traffic noise transmitted via the building façade) should be included, and, where windows are openable as part of the ventilation strategy, these should be assumed to be open for the purposes of calculations and open for measurements.

o Noise from occupants and office equipment (e.g. computers) should not be included in the measurements.

o Measurements should be made in at least four rooms in which noise levels can be expected to be greatest either because they are on the noisiest façade or because they are on a naturally ventilated façade.

o Where different ventilation strategies are used, measurements should be conducted in rooms utilising each strategy. Otherwise, measurements should be made in rooms on the noisiest façade.

o T in LAeq,T is taken as the duration of the normal working day (typically 8 hours between 09.00 and 17.00).

o Measurements need not be made over a period of 8 hours if a shorter measurement period can be used. In this case, measurements should be

Comentario [AR3]: Figures to be

reviewed against revision of Standard 4.1.6

made when external noise levels are representative of normal conditions throughout the day.

o Measurement periods less than 30 minutes may give representative values for indoor ambient noise levels and may be utilized where this is the case. However measurement periods shorter than 5 minutes should not be used.

o Measurements should be taken in a minimum of 3 locations in rooms at a height of 1.2 m above the floor level and at least 1 m away from any surfaces.
