HEVAC Air Conditioning Group – Information paper
Clarification on simulation software approved for use with Part L; May 2006

There is some confusion over which simulation software can be used to demonstrate compliance with Part L (2006) of the UK Building Regulations for non-domestic buildings. HEVAC has produced this brief information paper to help clarify the situation for its members and their customers/clients.

Guidance Note on the use of E-Procurement, including reverse bid auctions for HVACR products in the construction industry (August 2004)

The HEVAC Association actively supports e-commerce activities. Within this context e-procurement, which is progressively being used more frequently by customers and member companies alike, can be viewed as a valuable tool within an organisation’s purchasing strategy. Download from here; (172Kb .pdf)

On-line procurement, from a technology viewpoint, is broadly about automating parts of the process. Where implemented correctly, on-line procurement can support the process and benefit the customer and the business.

This Guidance Note on the use of e-procurement for the purchase of HVACR equipment and services provides an explanation of aspects of:

• E-Procurement and recommendations on its use and limitations • Product manufacturers views on Best Practice • Reverse Bid Auction issues

Air Cleaner User Guide (July 2004)

The user guide covers how to select and use Air Cleaners effectively to control tobacco smoke; create a comfortable environment; and meet health and safety standards. Download from here; (126Kb .pdf)

Air Cleaners come in all shapes and sizes and from a variety of suppliers, and the places in which they are used are equally diverse. This guide aims to help you to buy and site the right equipment for you; and to get an Air Cleaner working again if you have an older system already installed.

Rating scales of Seasonal Efficiency of Chillers - Seasonal Efficiency Ratings for Non-domestic HVAC Plant.

The report brings together the thinking behind the project, the development of the rating systems and the description of the schemes. The report will be used by the project team to publicise the rating schemes to a wider audience, and thereby promote their adoption. It is intended that it can be used by each of the partners to be placed on websites and used more in technical papers such as CIBSE or the Building Services Journal. Download from here; (188Kb .pdf)

In addition to producing a method for deriving a seasonal efficiency we have proposed a 'Labelling Rating' scheme that interprets this data into bands of seasonal efficiency that can be used to rate and compare boilers and chillers as appropriate. It is intended to take this forward in the context of the Market Transformation Programme.

The seasonal efficiency will also enable a better evaluation of the energy performance of a building under the requirements of the Energy Performance of Buildings Directive and therefore within the context of Part L2 of the Building Regulations.

HEVAC General Specification and Product Directory for Air Distribution and Related Equipment (August 2004)

The Air Distribution Group of the HEVAC Association was formed by Members involved in the manufacture and supply of Air Distribution Equipment. The equipment offered by these member firms covers the whole range of grilles, diffusers, air terminal devices, louvres, terminal units, fan coil units, chilled beams and ceilings, duct dampers, smoke/fire dampers and ventilators. The equipment is manufactured to a high standard of quality and design to meet the stringent requirements of the H.V.A.C. Industry.

This publication can be downloaded here and consists of a “General Specification and Members Product Directory” covering the full range of products in some detail. The contents will be of considerable value to those involved with the selection of Air Distribution Equipment.

HEVAC Standard Response to Subcontractor/Supplier Assessment Request

The HEVAC association has produced a questionnaire for member companies on which to present their company details and capabilities to potential customers. Entitled ‘Standard Response to Subcontractor/ Supplier Assessment Request’, the seven page document provides a standard format to enter your company information that includes, insurance details, QA policy, environmental policy, health and safety and company references among other details needed by potential clients. Link to it here. (Word file 440Kb)

Safe handling of refrigerants (May 02). The downloadable file is a position paper from the HEVAC Air Conditioning Group. They are of the view that companies should embrace the existing voluntary ACRIB scheme now, so that companies are prepared when the mandatory scheme comes in. This would help to avoid bottle-necks in training and registration when the mandatory scheme starts. Link to it here.

HEVAC Installation frame for fire dampers In the early 1980's HEVAC produced a specification for the construction and installation of installation frames for fire dampers. After nearly 20 years of working with the same specification, the HEVAC Fire & Smoke Damper Committee has issued a new specification - HEVAC6/5/83 rev1. The new specification has been issued as a result of advances in materials and production processes. Changes have been kept to a minimum and HEVAC has consulted with the BRE Fire Testing Laboratory and Warrington Fire Research Centre during its drafting.

HEVAC takes the IAQ initiative Now HEVAC, the Heating, Ventilation and Air Conditioning Association has taken up the challenge of promoting good Indoor Air Quality. It will be seeking to open up the debate on the topic of IAQ in the media, and encouraging all those with an interest in IAQ - employers, architects, building owners and users, developers, facility managers, health and safety officers and letting agents to gain access to the facts quickly and easily.

Flexible Hose Assemblies for Building Services Applications

Flexible hoses provide a flexible solution to linking pre-installed or prefabricated pipework to building services components such as fan coils and chilled ceiling modules.

Flexible hoses do however have a finite life which is strongly influenced by the quality of manufacturing, the care exercised by the installer and subsequent operating conditions. Hose assemblies, with rubber and plastic hoses, complying with the forthcoming HMSA standard (Flexible Hose Assemblies for Building Services Applications) are expected to have a minimum service life of 10 years when appropriately specified and correctly installed. Metal hoses adhering to this standard should have a life of 25 years.

This code of practice has been written to help specifiers, installers and maintenance operatives achieve the benefits that flexible hoses can provide while ensuring long term reliability.

The manufacturers who contributed to this guide can offer applications guidance for specifiers, installers and maintenance companies dealing with flexible hoses.
