Digging beneath the surface of buildings energy assessment

Toby Whiting is a student on the MSc Renewable Energy and the Built Environment course at CAT. He is studying the course alongside working as a buildings energy consultant. Here he reports on the module from October, which focuses on energy use in buildings. 

Another great week at CAT has flown by. As a domestic SAP and Code for Sustainable Homes assessor, this week has covered a lot of the areas that I’m familiar with. So was it a waste of time? No certainly not! Believe it or not, as a SAP assessor, I have never taken the calculation apart and played with it in a spreadsheet – it was always one of the things that I wanted to try but never made the time for. I’m pleased to say that this course has ‘ticked’ another box and allowed me to look at where the ‘numbers’ are drawn from and made me look at the SAP process from a new perspective.

High and low points of the week: Delivering my powerpoint in a session where students give presentations based on their essay topic; and the trip to an office designed to Passivhaus standard -I’ll let you guess which was the ‘high’ and which was the ‘low’ for me (but it wasn’t the one where I had to stand up and talk).

People can confuse and transpose terms like ‘Passivhaus’ and ‘Zero Carbon’ so it really has been good to get out and visit a building designed to consume less energy, rather than offset the carbon produced. For me nothing beats the experience of walking around a building like this.

Working as a consultant can be difficult because I spend a lot of time researching and advising others on the most efficient or cost effective solution and the flow of information is often one way. This course reinvigorates me and allows me to mix with like-minded individuals (both students and lecturers) and exchange ideas.

I have been able to challenge my opinions over a wide range of building performance related areas and learned some fascinating things from other student presentations. I’m a part-time student and won’t be back now until January – and I’m pleased to say I’m looking forward to it!
