Low Energy Building
by John Herbert - Director
Buildings are voracious energy users, in Hong Kong one
third of the total electricity generated in the year 2000 was
expended just to power air-conditioning systems.
Properly designed LEB (Low Energy Buildings) sometimes called "green
buildings" have minimal energy usage, systems operate more efficiently,
and of course saving money.
A common barrier for LEB's is the perception that the construction
cost will be significantly higher, yet studies show that green buildings cost no
more than traditional building methodologies. So how can this be the case, when
everyone knows green buildings cost more.
Kelcroft creates low energy building solutions for your business
A closer examination of the design process reveals clues why green
building can be competitive.
Kelcroft's IED strategies create innovative cost efficient low energy
buildings that having lower first cost (capex) and importantly lowest operating
expense (opex).
It is a question of focus, the traditional driver is cost, and that is usually
communicated as the effective prime mover for a construction project. However if
the primary focus is driven by the requirement to design better, cost effective
solutions are developed.
Making a difference
Kelcroft excels providing comprehensive holistic design approach, reducing
both first cost and your on-going expenses, ensuring that energy efficiencies
and conservation strategies are 'designed in', not an afterthought.
Whether designing for HKBEAM standards, LEED, OTTV, or
energy efficiency Kelcroft's strategies ensure that operating costs are
minimised.
Comparison
Compare the engineering data, below is a link to comparison calculation. The
Kelcroft design completely surpasses the conventional cooing tower design,
saving your significant opex and capex. This example demonstrates the Kelcroft
principal for a 1000 ton heat rejection.
Kelcroft's innovative design strategies lowers your annual operating cost
by 43%, saving HK$248,000 per annum.
Capital expenditure (CAPEX) is lower too, it is revealed that CAPex is
31% lower, saving approx. HK$469,00 first cost.
And the life time energy cost is 41% lower, saving more than HK$ 5,000,000
over the economic life.

Creating Green value
Green value is a difficult to determine, energy savings can be calculated, and a
dollar value assigned, but how do you assess the value of green building? There
is an increasing demand, judging by the specification of multinational
corporations, there is added value.
In the future, we will be able to compare values between a vanilla REIT, and a
green REIT, which do you think will perform better, and offer the largest return
over the medium - long term? On balance the green REIT will use less energy,
create less waste and will on the balance of probabilities offer a better
return.
Kelcroft's unique low energy building solutions lower both opex and capex
