Tulloch Homes Case Study

How Greenwood Airvac made a difference.

With a proud Scottish heritage stretching back 80 years, Tulloch Homes works across the private and social housing sector and is one of Scotland’s most distinctive and forward-thinking house builders.

In a recent project for Highland Council, which involved the construction of a total of 40 new social housing units in Inverness, the brief was to design and build properties which would be awarded the Scottish Building Regulations’ Silver Standard Statement of Sustainability.

Whole home solutions

The properties, which comprise a mix of one to three bedroom houses and apartments on the outskirts of this historic Scottish city, are of close panel construction, and, being new build, are very well insulated. In order to ventilate the properties, Tulloch Homes opted for  Continuous Mechanical Supply and Extract with Heat Recovery (MVHR), a whole dwelling ventilation system that supplies and extracts air continuously at a low rate, with the facility to be boosted as required. The unit is normally installed in the loft space or cupboard and rigid ducting supplies fresh, filtered air to the habitable rooms while extracting stale polluted air from ‘wet’ rooms. So, a high performance option, but also one that is cost-effective and meets the requirements of the Silver Standard.

Tulloch Homes had limited experience of heat recovery systems, so it approached Greenwood Airvac for both product and technical advice. “We already had an excellent relationship with Greenwood and they were very helpful in both the design stage and then with progressing the project every step of the way,” explains the Director of Tulloch Homes, Andrew MacMaster.

Greenwood recommended the new Vireo range of heat recovery ventilation units which were launched in January 2013 and offer the most cost effective solution for specifiers and installers.   Vireo is a Guaranteed Installed Product (GIP), a core Greenwood principle, which allows the installer 100% adjustability for on-site set-up and commissioning, and so complies with Building Regulations easily and simply. Plus the units are designed with Greenwood SMART technology to ensure performance continues to be achieved once in the installed environment.

For the larger properties, Greenwood advised using the Vireo 185WM heat recovery system. With specific fan powers as low as 0.60 w/l/s and heat exchanger efficiencies as high as 92%, Vireo is an excellent choice for reducing  in dwelling emission rates in SAP. It also offers outstanding airflow performance that ensures very low operational noise.

In the smaller houses and apartments, Tulloch selected the Vireo HR155WM. Ideal for properties with limited space, the Vireo HR155WM is a compact heat recovery system which can easily be sited in a 600mm wide kitchen cupboard. With increasing space restrictions and on-going focus to remove serviceable products from loft spaces, Vireo is one of only a handful of small heat recovery systems which still deliver excellent airflow performance in line with Building Regulation requirements.

Correct installation of the MVHR systems is essential to comply with Building Regulations too, and as an approved BPEC trainer, Greenwood was able to offer staff at Tulloch Homes the necessary accredited BPEC training in Domestic Ventilation, from installation and commissioning through to handover onsite, thanks to its mobile BPEC2U training rig. 

“We are extremely grateful to Greenwood for all their support from the start to the finish of this project, including providing the necessary BPEC training to our staff,” comments Andrew MacMaster. “The whole house solution that a heat recovery system provides is a great option for new build social housing and one that we will definitely be using again.”
