Installation of Air to Air Heat Exchangers to Multi Building Office Complex
Our client, a private national fuel and lubricants supplier, approached us to help improve their office environment and energy usage within their prestigious multi building office complex further to an energy survey being completed.
Their current system, multiple VRF systems, provided cooling and heating for the buildings however there was no facility to recover any heat or provision for the required air change rate, and as a result the heating and cooling of the office space was not effective.
One of the key elements to this project was the lack of space available for a new system. The ceiling voids were very congested , leaving very limited space available.
In addition, the buildings were operating from 8.00am until 5.00pm Monday to Friday so any works had to be undertaken out of normal working hours.
OUR SOLUTION
Having studied the design requirements, our solution was to propose the installation of eleven heat recovery systems that would not only provide heat recover for the office space and provide the fresh air requirements for this type of application. The design also had to take into consideration the ceiling void restrictions.
CHALLENGES
Throughout the duration of this project, we were faced with a number of issues, which we needed to overcome in order to bring it to a successful completion.
To solve the problem of the existing building primary steel structure, each ductwork run had to be designed to ensure system performance but also allow the ductwork to be distributed to the require areas.
As we were working on the multiple floors of the head office, we wanted to ensure that the project caused the minimum disruption possible the client’s business. We therefore arranged for all the work to be completed either at night or during the weekends which was incorporated into the full project programme.
The client had specified that they did not want any ‘noisy works’ being undertaken outside due to the neighbouring residential properties. Therefore, a full risk assessment was completed to allow all ductwork modification works to be competed inside the buildings.
An additional problem we were faced with was the issue of access, as we had to get all eleven units distributed to several floors. We therefore, after careful consideration and completion of a risk assessment, decided upon transferring the units from ground floor to upper levels via the staircases using powered stair climbers to provide a safe and effective solution.
SUCCESS
The technical expertise and problem-solving skills of our team were paramount in bringing this project to a successful completion within the time frame specified by our client. We were also delighted to be able to offer a 7 year Toshiba warranty on the equipment installed.
Client statement
“We went out to tender for these improvement works but, and as soon as Inergy got involved with the project they spent time developing a design solution that would specifically meet our requirements. Our main requirement of the HRV was to contribute in reducing our carbon footprint and at the same time, provide a solution that improves the working environment in two key buildings within our organisation. We awarded Inergy the project based on cost, expertise and technical know-how and I am pleased to confirm that the project was delivered to the highest standards for safety, management, and quality, on time and within budget”
