Fortunately, like much of the private sector, the building industry is not waiting for a national political consensus to seriously address climate change, and has stepped up with a combination of clever planning, innovative products, and whole-house systems which also help make the case why buying a newly constructed home is smarter than ever.
The challenge seems overwhelming: If the world hopes to keep temperatures
rising well below 2.0 Celsius (3.6 Fahrenheit) by 2060 from pre-industrial
times, CO2 emissions from buildings will need to drop by 85 percent. Between now and then – and as outlined in a
new initiative for the City of Los Angeles -- that means new buildings must be
zero-carbon by 2030, with both new and existing buildings becoming zero-carbon
by 2050.
The buildings in which we live, work and play demand energy
in two forms: The operating energy needed to fuel their daily operations, and embodied
energy, which includes everything required to construct them. Globally, almost
40 percent of energy used is related to building construction and operation,
and both steel and concrete require enormous sums of energy to produce.
According to the Department of Energy, U.S. buildings
account for 39 percent of primary energy consumption and 72 percent of all
electricity consumed domestically. Including
embodied energy, the United Nations calculates that our buildings contribute
nearly half of total U.S. emissions.
However, since we’re not about to go back to living in caves
and hunting for our next meal, what can we do?
Prepare.
Insurance companies, institutional investors and central
banks around the world are actively planning for the consequences of more
volatile weather across the world. The EPA
recently published a report advising communities on how to plan for the debris
left behind by natural disasters, while CoreLogic’s RiskMeter service combines its
vast databases with PhD-level scientists to model future risks to property
including floods, storm surges, wildfires, earthquakes, wind, hail and more.
Last fall was also the launch of The Investor Agenda, with
the motto “Accelerating Action for a Low-Carbon World.” This group of over 400 institutional
investors around the world, which together have $32 trillion under management, provides
a framework for them to share actions and commitments for four key areas:
Investment, Corporate Engagement, Investor Disclosure, and Policy Advocacy.
Here in the U.S., investing giants BlackRock, Vanguard, State
Street Global Advisors and others are backing the Sustainability Accounting
Standards Board, a nonprofit organization which seeks to standardize and
increase corporate environmental disclosures.
Given that 85 percent of respondents to Harvard Law School’s 2019 Institutional Investor Survey viewed climate change as the most important sustainability topic, it’s likely that both multi-national construction giants and public home builders will eventually face increasing scrutiny.
Central banks around the world, including the European Central Bank and the Bank of England, are also getting involved, with the goal of maintaining financial stability with new standards for financial disclosures and classifications for green assets.

In California, the government is requiring all new homes in
buildings of up to three stories to provide solar panels by the beginning of
2020, which is expected to add $8,000 to $12,000 to the sales price. Based on a 30-year mortgage, the state’s
Energy Commission projects that while these new standards will add about $40 to
an average monthly payment, they’ll also save consumers about $80 on monthly bills
for heating, cooling and lighting.
The building industry itself has already made huge strides
tackling climate change, but there is clearly more to do. Nationally, the percentage of commercial
office space certified by LEED or Energy Star in 2017 was 38 percent, up from
less than five percent in 2005.
Similarly, the share of green single-family homes rose from just two
percent in 2005 to 33 percent by 2017.
The share is expected to increase to nearly 50 percent for both single-
and multi-family homes by 2022.
Moreover, those builders which include smart home products
which also conserve resources – such as TRI Pointe Homes’ HomeSmart™ and
LivingSmart® systems – have found that sustainable homes generally find more
demand from buyers, with one study from the Earth Advantage Institute finding a
premium of up to eight percent over conventional homes. This premium extends even more to the resale
market, with green homes selling for up to 30 percent more than traditional
existing homes, and often selling faster.
That’s a win-win solution for everyone.
