CASE STUDY | BLOOM CLERKENWELL OFFICES year, he adds. Alongside system modelling, the team undertook a comprehensive analysis of the glazing at the design stage. As a result, it has been specified with four different G-values, depending on its location and orientation, the amount of daylight it is required to admit, and the heat gains it was beneficial to allow or prevent. The glazing contributed to the faades impressive thermal performance, which, when combined with the increased volume of air supplied to the floor plates, meant there was no need for additional heating or cooling at the floors perimeter. There is no fossil fuel heating plant in the building. Instead, heating, cooling and heat for domestic hot water is supplied from the adjacent E.On Citigen energy centre (see CIBSE Journal, April 2022). Connection to the energy centre was a condition of planning, but it also had benefits for the developer. Because heating and cooling is from Citigen, you dont need fossil fuel equipment in the building; all we need is space for heat exchangers in the basement, says Hargreaves. In addition to the Category A fit-out floors, Buro Happold was responsible for the design of the services to the Category B fit-out offices on Level 1. In these ready-towork office spaces, the office community is supported by HB Reavis smart workspace technology, as part of the building app. The technology empowers occupiers to manage their indoor working environment, with access to real-time data, such as indoor air quality and space utilisation. The app also facilitates a touch-free arrival and concierge services.

Hargreaves says Buro Happold is seeing more businesses wanting digital connectivity and smart capabilities rating as part of the remit for their building, because they see it as being an optimised smart building, providing resilient, reliable connectivity. He adds that occupants will be in little doubt that this is a smart building because the air quality is displayed visually as CO2 in parts per million on each floor plate, with a traffic light warning system if it gets too high. Post-pandemic, Hargreaves believes Well is gaining significant traction as a new default assessment methodology, given the wider understanding that the buildings in which we live, work, learn and relax profoundly impact our health, wellbeing and productivity. It just so happens that, on this project, the Well standard was in the brief from the outset.
