Since 1997 WINDTECH Consultants has been providing consulting services to assist in the design of Environmentally Sustainable Developments.

WINDTECH Consultants conducts assessments of the amount of energy required in residential dwellings for heating and cooling over the year WINDTECH Consultants use a second generation software package to analyse the thermal comfort for single and multi-unit dwellings. The accuracy of this software has been verified against field measurements, The software is capable of predicting the amount of heating and cooling energy required by the occupants to maintain thermal comfort throughout the year. This is performed by entering seasonal data relating to wind speed, temperature, humidity as well as information on the sun path. The software is capable of accounting for the effect of shading by other buildings or objects, the type of sub-floor, wall, floor, ceiling and roof construction, orientation and size and type of windows and doors, venting, level and type of insulation.

Where the design results in excessive heating and cooling loads the software enables the identification of the room(s) where the bulk of the heating gain/loss occurs and recommendations are made with regards to the most efficient and cost-effective method of reducing the heating and/ or cooling loads. This can involve one or more of the following methods:

• strategic use of insulation
• alteration of construction materials
• adjustment in the configuration of building openings.

WINDTECH Consultants’ expertise is recognised in the inaugural Urban Development Institute of Australia Awards which commenced in 2004. WINDTECH Consultants was associated with four out of the five winning entries.

The analysis using this software was performed for the 84 dwellings within this development at 157 Redfern Street, Redfern for the thermal component of BASIX. The analysis of the development indicates that a majority of the units experienced too much energy for cooling to maintain comfort for the occupants. An analysis of the design of these units indicated it had a significant amount of glazing orientated on the eastern, northern or western façade (southern hemisphere), thereby capturing a high amount of heat. Some of the various treatments implemented included improving the natural cross ventilation of the units by making several of the glazed systems operable, hence allowing the build up of heat to escape to the exterior environment. For measure involved improving the properties of the glazing systems and the inclusion of bulk insulation in the ceiling of the top floor to minimize the amount of heat transfer into the units. These measures have resulted in a significant reduction in the cooling loads for a large number of units and by as much as 79%.

WINDTECH Consultants’ expertise has been recognised in the inaugural Urban Development Institute of Australia Awards, which commenced in 2004. In fact, Windtech Consultants is proud to be associated with four out of the five winning entries.
For projects in New South Wales, Windtech Consultants also conducts BASIX assessments, including the assessment of features such as the Landscape Index, Water and Storm Water Drainage and Appliances.
