Profile - April 2004
existing buildings our typical activities involve analysis and reporting as
follows (where appropriate):
energy data and energy bill data and compare with Normalised Performance
Indicators (NPI’s) to determine areas of efficiency and inefficiency
for further detailed work.
water use data and water bill data and compare with benchmarks for the
thermal performance of the building envelope in terms of its thermal conduction
or heat loss as represented by U-values for each element. Assess the ability
of the building envelope to absorb heat; its thermal admittance as represented
by Y-values for each element.
potential upgrades to the building envelope.
actual and predicted annual energy costs, making adjustments for weather
conditions to state figures for 'the average year' based on 10-year average
actual and predicted carbon dioxide emissions.
Make a range
of proposals of no cost / negligible cost, low cost, and higher cost.
Hence, assist the client in budgeting and prioritizing energy & water
system modifications, improvements and replacements.
and / or life-cycle costs and savings for existing systems and for proposed
systems / solutions.
annual and / or life cycle carbon dioxide emissions stated in kilograms
or metric tonnes to put into perspective the increased or decreased Ozone
Depletion Potential / global warming aspects of proposals.
the ‘simple payback’ period for each recommendation, or alternatively
the 'compound payback’ period taking into account inflation and
Our typical activities for new
buildings are similar to those for existing buildings. However,
there is usually greater scope for more fundamental
proposals with new buildings because the process is starting from inception,
rather than modifying or replacing what is already in place.
