The main purpose of the study is to promote consideration of the issues and approaches available for costing sustainable buildings with a view to minimising cost overruns, occasioned by conservative whole-life cost estimates. The paper primarily looks at the impact of adopting continuity in whole-life cost models for zero carbon houses.

The study embraces a mathematically based risk procedure based on the binomial theorem for analysing the cost implication of the Lighthouse zero-carbon house project. A practical application of the continuous whole-life cost model is developed and results are compared with existing whole-life cost techniques using finite element methods and Monte Carlo analysis.

With standard whole-life costing, discounted present-value analysis tends to underestimate the cost of a project. Adopting continuity in whole-life cost models presents a clearer picture and profile of the economic realities and decision-choices confronting clients and policy-makers. It also expands the informative scope on the costs of zero-carbon housing projects.

A primary limitation in this work is its focus on just one property type as the unit of analysis. This research is also limited in its consideration of initial and running cost categories only. The capital cost figures for the Lighthouse are indicative rather than definitive.

The continuous whole-life cost technique is a novel and innovative approach in financial appraisal […] Benefits of an improved costing framework will be far-reaching in establishing effective policies aimed at client acceptance and optimally performing supply chain networks.

The continuous whole-life costing pioneers an experimental departure from the stereo-typical discounting mechanism in standard whole-life costing procedures.

An interview with Zeynep Ton, a professor of practice in the operations management group at MIT Sloan School of Management, about er latest book, The Case for Good Jobs: How Great Companies Bring Dignity, Pay & Meaning to Everyone’s Work.

She believes that leaders can either view their employees as a cost to be minimized, invest little in them and operate with high turnover, or they can see them as drivers of profitability and growth—investing heavily in them, designing their work for high productivity and contribution and therefore operating with low turnover.-- “the good jobs strategy.”

The secret sauce of good jobs strategy is four operational choices—focus and simplify, standardize and empower, cross-train and operate with slack—that improve productivity and contribution and make that higher investment possible.

The competitive costs of low people investment are even higher than the poor operational execution costs.

By making the work better and increasing pay, companies can better attract and keep their talent and enforce high standards, which improve execution and service, uplifting revenue. Few have examined this important topic more closely than Zeynep Ton, a professor of practice in the operations management group at MIT Sloan School of Management, best-selling author of The Good Jobs Strategy: How the Smartest Companies Invest in Employees to Lower Costs and Boost Profits.
