normalize data

• common location
• common time

establish comparison baseline

• the project’s original budget
• the project itself, without the green elements

findings

comparison of component costs

• High Performance buildings are happening
• There are two distinct families
• Demonstration projects
• ‘Mainstream’ projects – (a growing cohort)
• HPB are getting there by reducing consumption
• Costs are approaching ‘conventional’ buildings

• Passive night cooling
• Upgraded exterior insulation with thermal mass walls
• Ceiling fans extend comfort temperature range
• Custom operable skylights use prevailing breezes to induce internal airflow
• High performance glazing – no need for external shades
• Daylighting to all occupied spaces
• Skylights designed to provide equal light levels in summer and winter, and 15% higher

levels at equinox

• High efficiency LED lighting (.5W/sf)
• Integral daylight, occupancy, and temperature sensors at every light fixture
• Individually controlled desk fans and task lights
• Metering by load type (lighting, plug loads, mechanical)
• Building energy use dashboard
• Occupancy sensor controlled plug strips

• Performance based lease provides carrot (and stick) for good occupant behavior
• Added construction cost = $44/sf including 32,000 sf PV array
• Drastically reduced reserve requirements for maintenance and HVAC
• Reduced operating expenses – utilities, landscape, etc
• Demisability to reduce churn costs
• Unanticipated cost reductions (e.g. no mechanical screen)
• IF actual energy use meets predicted, than the financial model is more profitable than

standard practice (build to code)

• Future projects – higher rents and lease rates

concepts: financial

• High Performance Buildings are

coming

• Generally they are approaching

market costs.

• It is possible with the right team to

building them at market costs

• Generally the buildings are performing
• Of the high performance buildings

there is not a correlation between performance and cost.

What does this mean?
