The Government of Vietnam ratified the "United Nations Framework Convention on Climate Change" on the 3rd December 1998, indicating its commitment to environmentally sustainable development. Vietnam has also participated in the " Asia Least-cost Greenhouse Gas Abatement Strategy" which promotes energy efficiency as a key priority. The construction and manufacturing sectors in Vietnam are currently responsible for about 30% of total CO 2 emission in the country, and are therefore a target for CO2 reductions. As the result of an economic boom in Vietnam, there is a shortage of commercial buildings in general and of office buildings in particular. This is most evident in Hanoi and Hochiminh City which are enjoying substantial economic growth. Many new buildings are therefore being constructed in these cities, making their level of sustainability of particular importance.
Although there is a growing awareness among Vietnamese architects of environmental issues and hence the recognition of the need for planning and development of low energy environmentally-friendly buildings, there is a lack of readily available information and design tools to enable the design community to achieve this. It has been perceived that a simple and user-friendly calculation tool which can be used at the early stages of design would be very useful to enable architects to formulate the most appropriate design strategies and solutions. This paper describes the development of such a tool and sets out some results of its use.

Following introductory sections setting the issues in context, the paper presents the results of a parametric study of the effect of a number of building design variables on the overall energy performance of office buildings in Vietnam using the computer simulation tool TAS (Thermal Analysis System, developed by Environmental Design Solutions Limited UK). The paper then documents the procedure used for the development of the design tool, which is based on the results of the parametric study together with further computer analysis using TAS. An explanation follows of how the tool which is capable of optimizing critical design decisions such as the distribution of glazing and the effect of orientation on energy loads should be used. The overall aim of the paper is to provide the design community with a simple tool, for use at the early stages of design, for improving the overall environmental performance of office buildings in Vietnam.

Viet Tuan Do is currently working for Sustainable Energy Action Ltd (SEA/RENUE), a leading independent company and an environmental charity working in London in alliance with architects and construction professionals to promote the sustainable use of energy in housing, businesses and transport in Greater London and nationwide. He is also a KTP Associate at London South Bank University and a Research Associate at Lincoln School of Architecture, United Kingdom. Before going to England, he had some years of experience in the field of energy efficiency and sustainable architecture in Vietnam, working with The Deringer Group Inc (USA), OVE (Denmark), and Vietnam Ministry of Construction. Being the first Vietnamese awarded an E7 Sustainable Energy Development Scholarship from leading electricity companies of the G7 nations, he came to London in 2003 for a postgraduate degree. He received a Masters degree in Environmental Design in 2004 from University of London (The Bartlett School of Architecture, Building, Environmental Design and Planning at University College London) with a dissertation analysing energy efficient design features and presenting the development of a design tool to assist sustainable architecture design in commercial buildings in Vietnam.

Alan N. Young is currently responsible for the MSc Built Environment: Environmental Design and Engineering course at The Bartlett School of Graduate Studies (University College London), which deals with the design and operation of environmentally-friendly and healthy buildings. After completing a BSc in physics (at Queen's, Belfast) and a PhD in physical chemistry (at Cambridge), he switched to the building industry and worked in the building services sector as an air conditioning design engineer, before taking up an academic job at the Bartlett. Recent research has included work on design guidelines for healthy environments in air conditioned and naturally ventilated commercial buildings and on carbon monoxide levels and ventilation strategy in housing. Current research work, funded by the EPSRC, is reviewing the current and expected future role of residential air conditioning in the UK's carbon reduction targets.
