	In 1998 and 1999, the self-contained water heater used as little as 3 kWh/sq m of gas, even less than in 1997. Consumption then rose to 4.4 kWh/sq m in 2000 and 5.5 in 2001, perhaps owing to temperature adjustments. In 2003-08, consumption nearly tripled to 12-14 kWh/sq m, owing to a change to 24/7 operation at 55C (65C on Sundays), resulting from concerns about legionella. In 2009 a new condensing water heater was fitted and its gas use fell to 11 kWh/sq m. Although the building is more heavily used, most of the extra consumption in relation to the PROBE survey data is thought to be from standing losses from lightly-insulated and uninsulated pipework.

	Too many new public and commercial buildings fail to live up to their expectations for energy savings and user comfort, but can the good ones maintain their performance? With support from CIBSE, a team of experts returns to a university building that was found to perform exceptionally well in the late 1990s.

	The Elizabeth Fry Building benefited from a client representative, Peter Yorke, who was seeking good-quality, robust, lowenergy buildings at normal cost levels and had gained considerable experience from previous UEA projects. The design team was keen to oblige and had worked together before on the adjacent Queen’s Building. The result was a ‘keep-it-simple-and-do-itwell’ design. During construction, critical details affecting insulation and airtightness were followed through by the team with Elizabeth Fry’s builder Willmott Dixon and the university’s clerk of works, who visited the site daily.

	The 2011 survey shows that occupant satisfaction has fallen back a little, both absolutely and relatively, because the reference dataset now includes more buildings with good performance levels. However, average comfort levels are still good (see figure 2) and are typically within the second decile of the dataset. Occupants also rate the quality of cleaning very highly.

	In hindsight, with changes of kitchen, stores, and so on, to offices, the question arises as to whether the building should have had a more uniform pattern of windows to facilitate changes. On the other hand, does management really need to alter buildings so much? Several occupants expressed regret at losing prime teaching and meeting space to administration facilities.

−	Now that UEA has many more buildings to look after, it is a credit to the robustness of Elizabeth Fry’s design and fine-tuning and to UEA’s maintenance and cleaning that its performance remains good. Twenty years after it was designed, why have so few newer buildings caught up? We hope to explore the broader issues in a future article.	+	Now that UEA has many more buildings to look after, it is a credit to the robustness of Elizabeth Fry’s design and fine-tuning and to UEA’s maintenance and cleaning that its performance remains good.
