CFD Modelling for Car Park Ventilation Systems – a guide for designers and regulators - Feb 2007
This document sets out the information and parameters that the designer should incorporate into the design of the CFD model. It is intended that this document should be of use to the designer in producing and running the CFD model and in writing the CFD report. It also provides recommendations on the information to be provided to the approving authority within the designer’s package of supporting information when submitting the CFD analysis for information and/or approval of design intent.
The Smoke Control Association is primarily concerned with ventilation design for the removal of smoke and heat as discussed in the British Standard, but, recognising the dual use of systems, this document provides guidance on usage for both smoke and heat removal and vehicle emission ventilation. This document is intended to support the recommendations of BS 7346-7.
Guidance on Smoke Control to Common Escape Routes in Apartment Buildings (Flats and Maisonettes) - June 2012
The prevention of smoke spread through buildings is of critical importance, but little guidance is currently available in one publication. This document provides details and gives recommendations not previously covered in other standards or codes of practice and should make a significant contribution to improved understanding of smoke control systems. Originally published Nov 2010; updated to Revision 1 in June 2012. Revision 1 is available to download from main SCA page.
Design of Smoke Ventilation Systems for Loading Bays & Coach Parks – a guide for system designers - Nov 2010
This document sets out to give guidance to the design of ventilation systems for loading bays, service yards and coach parks and lists the options available to the design engineer. This document should also be of assistance to the regulating authorities in assessing the suitability of systems submitted for their approval.

HEVAC Cold Store Air Curtain Guide - NEW September 2009
Controlling the climate in and around cold stores is very complex because of the large temperature difference between inside and outside the cold store. Within the food sector quality control and precise temperature regulation is critical, and this guide covers benefits of air curtains, design factors, applications, case studies and controls.
HEVAC Guide to Filtration - A Training Manual - NEW October 2008
This manual has been prepared especially for use by heating, ventilation and air conditioning engineers and specifiers as a valuable source of reference. It contains in-depth information on aspects of air filtration, which we are sure will be of benefit to all who will use it.
HEVAC - Air Curtain Guide Brochure
The HEVAC Air Curtain Guide is a basic introduction to air curtains and covers these topics: what is an air curtain; how do air curtains work; where air curtains are used; benefits of air curtains heating sources; design factors to consider when selecting an air curtain; design procedure for new build; controls
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.
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
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.
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.
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.
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 issued a new specification in 2002 and again in 2012 - HEVAC6/5/83 rev2. 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.
