Construction

Our landscapes, cities, buildings and homes are something that all of man kind interact with on a daily basis and are incredibly important to our survival.

These structures use tremendous resources and hence are a prime focus for all humanity to ensure that they are sustainable. It is estimated that energy use in buildings is the equivalent to the energy used in industry and transportation combined.

Cement

One particular part of constructing our buildings that is ubiquitous is the use of concrete. Unfortunately producing concrete consumes vast amounts of energy, emits some of the most deadly of pollutions and approximately one ton of carbon is emitted for every ton of cement produced..

There is a tremendous amount of innovation going on in the world of cement. Some folks are working on making concrete's production more environmentally benign and its use in the process of construction more friendly to the environment.

Other innovators are working in the area of alternative bonding agents to cement. New bonding agents enable concrete to be light weight which will enable more of the construction process to be done in a factory so that building sites will become more "assembly only" oriented.  

Materials

Making a house out of wood is the equivalent of making your house out of matchsticks. Trees are a great way to sequester carbon and are renewable, but matchstick houses rot, catch fire and are easily decimated by high winds.

We will look back in 20 years and notice that all new houses are made with renewable and low carbon concrete systems and we are likely to think "what the heck were we building houses out of wood for"?

Heating and Cooling

Our buildings use a tremendous amount of the nations total power consumption and though florescent light bulbs help, LED's will help even more, the real power hungry devices are the heating and cooling systems.

Solar hot water heaters coupled with radiant floor heating offer a low energy heat solution. Water based air conditioning systems that are the modern equivalent of swap coolers offer huge efficiency gains over traditional air conditioning in water accessible areas.

Windows

Windows are the hardest part of any building to insulate. Most windows have very low R values with today’s good quality, dual-pane commercial or residential windows coming in at R-1 to R-3, dramatically lower than a typical R-13 wall.

There is considerable work going into developing vacuum sealed glass. These are hard to manufacture because of the differential temperature between outside and inside a building can be huge, so the glass must expand at different rates. Making this seal work is not easy but a number of companies are working on solutions to this problem. In addition to this temperature differential problem, spacers are needed to keep the panes of glass away from each other due to the vacuum and this reduces the windows visibility.

A window with an R-12 center-of-glass insulation level at a reasonable incremental cost is the holy grail of window construction. This insulation level would convert most windows in cold climates into energy suppliers rather than being one of the largest sources of heat loss.
