There is a prevailing assumption that new buildings perform exactly as they were designed. It is taken for granted that from the day the occupants move in, everything will be working as intended when the details were drawn up months, if not years, before. But as most designers know, theory and practice rarely coincide.

Built environment consultancy BSRIA and the Usable 好色先生TVs Trust have decided to tackle this problem. The tool they have invented for the purpose is the Soft Landings framework, which aims to make moving into a building hitch-free and ultimately to improve the long-term performance of buildings, from the comfort of the occupants to the amount of energy used.

Practical completion always used to be the stage when the professional team disbanded, with its members racing each other to get off site first. Soft Landings, conceived by Mark Way when he was chairman of architect RMJM and trialled when constructing the centre for mathematical sciences at the University of Cambridge, offers a different approach. The initiative provides a framework to keep the professional team together after practical completion, providing a period of 鈥渉and holding鈥� during which the client and occupants can become accustomed to their new building.

How does it work?

The Soft Landings framework is a set of procedures and exemplary checklists that the design team can follow 鈥� it鈥檚 not licensed, so users are free to use and adapt it as they like. The attraction for clients is that by going through this process they get a building that is ready to go operational straight away. For the design team it means fewer recalls and the opportunity to learn lessons that they can incorporate into future projects.

According to Roderic Bunn, project manager at BSRIA: 鈥淲e know that few buildings are truly operationally ready at handover, and we also know that energy consumption is often far higher than anticipated. The Soft Landings framework provides a simple mechanism by which project teams can remain involved after practical completion in order to identify emerging problems, resolve causes of energy wastage and help occupants gain full control over the building鈥檚 environmental systems鈥�.

Handover is the crucial stage of Soft Landings, as it offers the opportunity to fine-tune and debug the building鈥檚 systems and explain to facilities managers and occupants how to get the best out of their new environment. It can be especially valuable in buildings where, for example, low-energy passive or mixed-mode ventilation systems are used as these can involve greater occupant interaction and fine-tuning than a fully air-conditioned office. In practice it means having members of the original team on site for a period 鈥� typically up to two days a week for the first two months 鈥� as the occupants move in.

However, along with the initial period of aftercare, the framework allows for a programme of post-occupancy evaluation that can run for up to three years. The project team can use this to benchmark and improve the building鈥檚 performance and sustainability over the long term.

According to Rab Bennetts, director of architect Bennetts Associates, closing the loop from design, construction, operation and feedback and into design again is essential to provide better buildings and a more effective service to clients.

The big question, of course, is cost. Bunn suggests initially setting aside about 0.1% of the contract value. 鈥淚t depends on what you鈥檙e aiming to achieve. If you鈥檙e planning to do an energy audit of an existing building to benchmark against and full post-occupancy surveys, then the costs will be higher but a lot of it just involves a different approach rather than additional meetings and time.鈥�

Bunn also argues there is a strong case for architects and consultants not to charge full rates for additional time. 鈥淭hey will benefit from the work, particularly when it comes to the lessons learned and this should be taken into account鈥�.

These days, developers and project teams are looking ever harder for a competitive edge. Soft Landings might be just what they need.
